Connecting the dishwasher to hot water. Is it possible to connect the dishwasher to hot water? How to connect a dishwasher to hot water Is it possible to connect a dishwasher to hot water

A useful appliance in the kitchen is a dishwasher. It helps to save water, valuable time that can be spent on proper rest, communication with family, and doing household chores. If the family is large and everyone loves delicious home-cooked food, by the end of the day a lot of dishes accumulate, left over from preparing and eating food.

This wonderful device will easily cope with the task of washing dishes; the quality of the wash will surprise the demanding housewife. When the machine is purchased, it needs to be installed and connected. Below is a step-by-step instruction that will tell you how to connect a dishwasher with your own hands to the water supply, cold and hot water, sewerage, electricity, how to choose the right place, how to install the equipment.

Dishwasher in the kitchen

Dishwashers are gaining great popularity and are often found in apartments and houses. Washing dishes in a machine is convenient and comfortable. The device allows you to save water consumption and electricity required to heat water. It is not surprising that a dishwasher is present in many homes or is planned for the nearest purchase. The best time to decide to purchase this device is when renovating a kitchen.

If the place is determined and prepared, you can install the machine at any time. Installation work is not complicated, you can successfully complete it yourself. What is needed to connect a dishwasher?

The dishwasher does not require any special installation. After installing the machine, you will need to connect to the main networks:

• electricity,
• water supply,
• sewerage.

In some cases, you can connect the device to hot water, but not all models allow this method; this should be indicated in the instructions.

Preparing the installation site

First you need to decide on the location of the equipment. It is advisable to foresee the placement location in advance in the kitchen design, but you can easily install it at any time if the necessary networks are nearby: water supply, sewerage, electricity.

The optimal location is near the sink. Before purchasing, it is necessary to evaluate the amount of space available, because the equipment is offered in different sizes. To gain additional space, it is worth giving up one kitchen cabinet.

Freestanding models have standard widths:

• 60 cm,
• 45 cm.

The standard depth is 60 cm, height is 85 cm. In most cases, the machines are equipped with legs that allow minor adjustments (raise, lower by 2-4 cm). Some free-standing models allow installation under the kitchen countertop; their top cover can be removed. Built-in machines have similar dimensions.

Installing and connecting a built-in machine will require great accuracy in measuring the installation location. The built-in option must be provided at the stage of ordering kitchen furniture. When the machine is built-in, any intervention is difficult or impossible.

An interesting solution is a compact dishwasher installed on the kitchen table. The compact model resembles a home microwave oven in appearance and does not require much space. Compact appliances will complement a small kitchen where it is impossible to install standard-sized appliances. Compact models are purchased by residents of rented apartments, childless couples, and bachelors.

What kind of water can I connect to?

The machine must be connected to a water supply, usually cold water. Some models can use hot water at 60°C. However, the profitability of this option is noticeable in the following situations:

1. water is heated through the use of alternative energy sources (solar collectors, heat pumps);
2. hot water is supplied by a boiler or gas heater, you can save a little, because the energy from burning gas is cheaper than electricity;
3. The water is heated by a solid fuel boiler or a fireplace with a water jacket.

Using hot water is useful if the heating element burns out; replacing this component is expensive. Unfortunately, in modern technology, spare parts do not last very long; they are sold assembled, as a unit, so replacement is expensive. As the experience of the author of the article shows, this rule applies to little-known and popular brands present on the household appliances market.

Before connecting to the water supply, you need to make sure that the water:

1. not too hard
2. does not contain large amounts of iron, manganese.

What hardness is acceptable?

• if the total hardness is less than 7 on the hardness scale, there is no need to use conditioner - the water is considered soft;
• If the total hardness exceeds 7, water softening should be used.

When heated, compounds contained in water decompose into insoluble carbonates, forming scale (a phenomenon well known to people who use electric kettles).

Increased water hardness can:

1. damage the device,
2. significantly reduce the quality of washing.

To reduce hardness, it is necessary to install appropriate main filters at the entrance of the water supply to the apartment or directly in front of the equipment.

Connection to water supply

You can connect the water to the dishwasher yourself. Each machine is equipped with a water supply hose. Depending on the manufacturer, the lengths of the hoses are:

If the hose in the purchased model is too short, you need to purchase an extended version. It is not recommended to extend water hoses by connecting them to each other, as this may cause water leakage at the joints.

An easy way is to connect the dishwasher to the water - under the sink. Flexible high-pressure hoses that need to be hidden in the sink cabinet are suitable for these connections (the hose is included with the machine).

To connect you need

1. Turn off the main water supply valve in the apartment.
2. Unscrew the pipe.
3. Water is supplied to the sink through 2 pipes (cold and hot). A tee with a faucet for the machine is installed on the cold water pipe. If the dishwasher is connected to hot water, a similar tee is installed on the hot water pipe.
4. We screw the high pressure hose to the faucet and to the machine.

Checking the tightness of the system

After installing the pipes, it is necessary to check the tightness of the system. The tightness is checked by opening the main tap in the apartment, and then after the first start of the machine.

It is important to check the pressure in the water supply system. To operate the device, it is sufficient to provide a water supply of at least 10-15 l/min; the water pressure must have the value specified by the manufacturer (range: 0.1-1 MPa).

Connecting a dishwasher to the sewer - options

Most dishwashers have their own hoses and tubes for draining used water. They have different lengths, but the outflow pipe, if necessary, must be lengthened while maintaining the necessary tightness.

Attention! To prevent unpleasant odors from appearing in the dishwasher, it is important to ensure that wastewater is removed at the proper slope.

If the sewer system is being built from scratch, it should be remembered that near the location of the device there must be an outlet to the sewer with a diameter of at least 4 cm, preferably with an inlet opening directed upwards, possibly extending horizontally from the wall. The bent end of the flexible drainage hose, which is usually equipped with the machine, must be placed in the drain pipe and secured to the wall with a special handle so that it does not fall out.

Connection to the sewer, photo

You can use a special rubber plug with a hole for the hose or a plastic sewer connection with a 1/2-inch connection to attach the drain hose.

If there is no drain to which the dishwasher can be connected directly, you can use a sink trap. You will need to replace the top fitting of the siphon with a tee for connection with a side connection. The design of some siphons includes a tee fitting for installing a drain pipe, then you do not have to install anything additional. This connection is used to install the drain hose. To increase the tightness of the connections, you must additionally use clamps.

The minimum height of the drain hose is 40 centimeters. The height of the drain hole is usually specified by the manufacturer in the instructions. Compliance with this slope will protect against unwanted odors from sewer pipes.

Electrical connection

All devices available on the market operate at a nominal voltage of 220 V and have an electrical cable with a plug.

Important! The outlet must be grounded.

It is worth noting that for safety reasons this should not be done when connecting to the mains. Dishwashers are equipped with a system that interrupts the water supply when malfunctions or internal leaks occur.

What not to do!

• An extension cord must not be used. According to safety regulations, the machine should be connected directly to a grounded outlet.
• Location of sockets. If the appliance is installed next to a sink, there is an electrical outlet nearby and there is a risk of contact with water. You should ensure safety - consider installing a moisture-resistant outlet. This issue is especially important if children live in the house.

Using the above rules, you can easily connect the dishwasher to the networks with your own hands. You will need a little skill, basic tools, a tee, a faucet. Installing a dishwasher is not difficult, it is important to follow the recommendations exactly. If the task is to do the installation professionally, to prevent sudden flooding of the apartment, it is better to entrust the work to a plumber.

Dishwashers, even with A+++ efficiency, spend a certain amount of electricity heating water. This raises a legitimate question for the buyer: is it possible to connect a dishwasher to hot water and not spend money on electricity? Let's try to figure it out.

Specifications

According to the technical specifications, dishwashing equipment generally operates with water not hot at 60°C, and units from Bosch do not exceed 20°C. This means that exceeding the specified temperature will definitely lead to rapid breakdown and loss of warranty repairs.

Causes of malfunctions:

• High water temperature leads to failure of the filtration system.
• Tap hot water is more contaminated than cold water.
• Rinsing and soaking dishes is done with cold or warm water, otherwise food particles will stick to the dishes.
• High temperatures quickly wear out hoses and gaskets, bend pipes, and weaken connections.
• Frequent shutdowns of hot water will prevent you from using the dishwasher regularly.

Hot water connection

Many manufacturers, focusing on consumer demand, produce machines with the ability to draw hot water from a water supply.

The benefits of a dishwasher with a connection to hot water are obvious, as reviews say - the cost of electricity when heating water is eliminated. In addition, the process of washing dishes is noticeably accelerated, because... No time is wasted heating water. However, due to debris in tap hot water, you will have to install filters.

You can also consider another option for economical use of a dishwasher - connecting to a gas water heater. Here you can independently regulate the water temperature. A dishwasher with hot water and water heater connections is possible. In this case, the advantage lies in the purity of the water, because... its quality is the same as that of cold, i.e. no need to install additional filters. Therefore, some buyers consider the column as an opportunity to save money when using a dishwasher.

Other hot water connection options

Some manufacturers produce dishwashers with hot and cold water connections. In this option, the device itself mixes the water to the required temperature. The instructions included with the equipment, which contains a wiring diagram for the dishwasher, will help you make the connection correctly. Reviews speak of the undeniable benefits of this method.

If connecting to hot tap water is at the forefront when choosing a dishwasher, then you should first familiarize yourself with the technical characteristics of the device. The manufacturer must indicate this possibility in the instructions.

Installation and connection of the dishwasher can be divided into 3 stages:

• preparation and securing of built-in equipment in a special niche

• connection to the electrical network

• connection to water supply and sewerage

Let us consider in detail, indicating common errors, precisely the stages of installation to utility networks and communications.

Electrical connection

To connect the dishwasher to a 220V network, you will not need many materials:

A dishwasher (DMM) is not a particularly powerful consumer of electricity, such as a hob (from 7 kW and above). Its power usually does not exceed 2.0-2.5 kW.

Modern energy consumption models correspond to class “A” or “A+”. That is, in a year, approximately 220 kW will run on your meter.

Despite this, it is still advisable to connect the PMM at the repair stage to lay an independent cable line in a separate groove.

If your renovation has been completed a long time ago, and after purchasing the equipment you don’t feel like scratching the walls again and ruining the wallpaper, then you can make do with the existing outlet. Just be sure to make sure that it is protected by an RCD.

Connecting a dishwasher through a simple modular machine is extremely dangerous.

The socket should be placed at a convenient height - up to 90cm from the floor level.

At the same time, place it on the right or left side of the washing machine, but not behind it.

Please also take into account the fact that the total length of the cord with plug for this equipment rarely exceeds 1.0-1.5 m. Based on this, choose a place for the outlet so that you don’t have to use an extension cord later.

The outlet itself must, of course, be grounded. But not everyone has this same grounding. Especially in apartments in old high-rise buildings.
Therefore, many people use regular ones, and everything seems to work fine. However, the level of protection will no longer be sufficient.

Roughly speaking, if there is a grounding contact and there is a current leak, then you will not even be able to turn on the RCD. The consequences of these leaks, even small ones, can be quite lethal.

With a simple socket, the shutdown will occur only at the moment when you touch the body, which is already energized.

And you will still feel this electric shock, at least at the initial moment.

Connection to water supply and sewerage

Connecting the dishwasher to the water supply can be done in two ways.

The first is when you are at the stage of construction or major renovation, and you can afford to lay separate pipes, trench walls, etc.

The second is when your entire kitchen has already been installed and all finishing work has been completed. At the same time, you bought a dishwasher and you need to connect it all somewhere, to the existing water supply and sewerage system with minimal alterations and hassle.

Installation of new pipes

For major installation you will need a varied range of materials:

When installing pipes, the socket method is used. To do this, you will need a special apparatus for soldering polypropylene pipes.

The total length of the pipe and the number of fittings are selected individually. This depends on how far the dishwasher is from the cold water collector.

To begin with, mark the route where the pipes will be laid from the distribution manifold to the installation site of the PMM.

Then, use a wall chaser to cut to the required depth.

Next, connect the PPR connectors with a union nut to one of the manifold outputs.

Cut a piece of pipe so that it will last until the first turn or corner. At the same time, do not forget to leave a margin of 15mm for connections on each side.

Connect the pipe and fittings using the soldering method, controlling the position of the elbow.

After connecting all the pipes along the marked area, install a water socket at the very end. Be sure to fix it on the wall.

Next, screw a ¾-inch male threaded elbow into the water socket.

Mount the water supply hose onto the angle.

The AquaControl or AquaStop system with which it may be equipped should protect against leaks in the event of a breakdown and automatically stop the water supply.

Turn on the water and check the entire system. If everything is fine, you can finally seal the groove.

Drain connection and installation in the kitchen opening

All that remains is to connect the drain hose from the PMM to the sewer outlet through an adapter collar of the appropriate diameter.

Do not forget that the drain pipe must be mounted at an angle, allowing for a 1cm height difference per 1m of length.

And the drain hose itself has a bend at 70cm from the floor. That is why it is attached to the top of the dishwasher, and not at all so that it does not dangle.

All that remains is to connect the washing machine to a power outlet and check the functionality of the entire system. Then secure it in a specially prepared opening.

By the way, some models, for example from Siemens, have non-standard sizes. Therefore, think about your kitchen furniture in advance.

When installing in an opening, do not forget about the metal plate that must be nailed to the bottom of the tabletop (for the Bosch model).

This thing is mounted at the very edge and is a vapor barrier, like a screen. With it, the countertop will not swell from steam.

For some reason, many people throw it out and replace it with aluminum tape, securing it both to the table top and to the side walls of the car.

Electrolux, instead, comes with something like a piece of rubber that sticks on the sticky side.

After installation and connection, the first wash should be done without dishes, using powder or special cleaning tablets.

This procedure should destroy all bacteria and deposits formed after long-term storage in the store.

Connection via sink siphon and faucet.

There is a simpler option for connecting a dishwasher, in which there is no need to install separate pipes for draining and supplying water.

You only need to change two things:

It differs in that its design already has a place for connecting the drain hose - a fitting, and sometimes two.

You can, of course, redo the sewer drain by installing an additional pipe and seal there.

The whole thing is inserted by hand, without using any special tools.

However, do not forget that connecting dishwashers and washing machines directly to the sewer pipe may be accompanied by the appearance of unpleasant odors.

Experts advise making this connection through a check valve.

Kinking or bending the hose at a height, which should act as an alternative to the valve, only helps with constant use of the equipment. Of course, your water will not return.

However, if the system stands for a couple of weeks without work and water (for example, in a country house or in a country house), everything will dry out and the stench in the kitchen will be very sensitive.

Through it, the water itself will flow into the machine. It is installed instead of the standard connector that goes from cold water to the mixer.

Screw this tee to the cold water supply hose or pipe.

Next, change the siphon. Unscrew the screw from above, holding the siphon itself from below so that it does not fall.

Disconnect the drain from the sewer. To do this, simply pull it towards you with force. It should come out of the rubber retainer.

Assemble a new siphon from the components, not forgetting the gaskets, and install it in place of the old one.

Connect the flexible drain pipe to the sewer pipe. All that remains is to connect the dishwasher drain hose to the siphon tube through a special adapter.

Included with this adapter, be sure to look for a valve, it blocks the reverse flow of water.

Fill the sink with water and check that there are no leaks anywhere.

Errors and rules

1 Connection of the dishwasher in the 220V panel from the machine.

Remember that all equipment and devices in your house and apartment that are interconnected with water and electricity - a boiler, instantaneous water heater, washing machine, including a dishwasher - must be connected through:

There shouldn’t be any simple modular machines, much less traffic jams, here. Reliability of protection and your safety in the event of an electrical breakdown of the wiring should come first.

2 Installation of the dishwasher very close to the wall.

As a result, the supply or drain hoses may become pinched, impairing water circulation. An error will constantly appear on the display.

And you won’t even guess why. Therefore, the minimum distance from the wall should be at least 5cm.

3 The machine must be on a level surface.

If the installation is uneven, you will have problems with the quality of washing dishes. There may even be a water leak.

For example, Electrolux models allow a deviation from the horizontal of no more than 2 degrees. This whole thing is checked at the building level.

And it is regulated by twisting and twisting the legs.

The back leg of most models is adjustable from the front. Using a special screw in the lower central part.

When adjusting the legs, according to the instructions, the machine must be raised to the maximum so that there are no gaps left between it and the table top.

4 Installation of a 220V socket under the sink.

Although this may seem like the closest and most convenient place to connect the power plug, try to avoid this type of connection.

The slightest blockage and subsequent leakage guarantees a short circuit and fire. For the same reason, it is not recommended to place the extension cord directly behind the dishwasher.

If the factory cord is not enough to reach a stationary outlet, then connect the carrier away from the hoses, at the greatest possible distance.

5 Connection to hot water.

Remember that not every PMM can be connected to a hot water supply system. Be sure to read the instructions, otherwise the device will fail much earlier than its warranty period.

In addition, the water temperature in this system may be higher than that for which the sink is designed (usually no more than 60 degrees). Even if it supports such a connection.

Also keep in mind that the hot water in our pipes is dirtier than cold water. Therefore, experts recommend connecting to cold water.

It makes sense to connect to a hot one only if you have your own heating and a gas boiler. Otherwise, it will be a penny saving on electricity, which will ruin an expensive dishwasher. 6 Extending the water supply hose.

It may well happen that the factory hose, which has a standard length of no more than 1.5 meters, is not enough for you. Therefore, you will have to buy more footage.

The most important thing is not to bite off, unscrew or throw away the main one. It can come with leak protection.

Wires are hidden inside it and when a break occurs, a short circuit occurs and the valve installed at the end automatically shuts off the supply.

Therefore, when lengthening, simply extend the existing one.

7 Flax for thread sealing

If you are not a plumber and do not know how to properly and in what quantity flax is wound to seal threaded connections, then it is better for you not to use it.

You may encounter this when reworking the connection of the dishwasher to the siphon and installing a tee for the cold water supply.

If used in excess, the flax will eventually swell and the flimsy union nut may burst, ultimately leading to a flood.

In such places it is better to use a factory rubber gasket or fum tape.

In the last decade, dishwashers have become extremely popular. They can significantly save time and make the work of the kitchen housewife easier. However, all these devices have one serious drawback: to heat water you have to spend a large amount of electricity.

Electricity today is not cheap, so you can increasingly hear the question: is it possible to connect a dishwasher to hot water? To understand how such a connection will affect the operation of the unit, it is necessary to study the hot water supply technology and the operating principle of the entire system.

Traditional way to connect water to the dishwasher

Almost all modern dishwashers are designed to be connected to cold water. This method is traditional. The device comes with special instructions describing the detailed connection technology.

Hot water supply to the dishwasher

It all depends on the product model. Not every device manufacturer provides this feature. To supply hot water, you must have a special hose. It is usually marked with a red stripe. Moreover, all hoses are made of different materials. Each has its own properties and is designed to fulfill specific requirements.

Features of connecting hot water to a dishwasher

To connect the dishwasher, you must first make sure that such an operation is possible in principle. The permissibility of the connection is indicated in the instructions for the correct use of the device. In some models, the manufacturer has provided the possibility of such a connection. Moreover, you can immediately use a combination of two hoses.

What is needed for work

To organize the supply of hot water, you need to prepare several tools in advance, as well as special material.

• Water hose that can withstand high temperatures.
• Brass tee equipped with valve. Silumin equipment is not suitable for hot water supply.
• Filter for water purification.
• Pliers.
• Adjustable wrench.
• Teflon tape.

Technological process of connection

To connect the pipeline, you must perform several operations in a certain sequence:

• turn off the water supply;
• prepare the pipe outlet;
• install a tee;
• connect a water intake hose to it;
• install a filter on the free end that performs rough cleaning;
• connect the dishwasher.

Safety precautions

You must always remember that hot water only works at high pressure. Saving on a hose can lead to rapid breakdown of the entire system. The connection is carried out strictly according to the instructions. All connections must be sealed with special Teflon tape. Before you start using the dishwasher, you must perform a test run. The presence of minimal leaks is strictly prohibited.

Note! The dishwasher must be grounded. Failure to do so may result in severe electric shock.

Saving

This question is quite complicated. It is impossible to answer it unequivocally. This is due to several reasons:

1. The dishwasher can only operate at temperatures not exceeding 70 degrees. If it rises higher, the filtration system will break down.
2. It is impossible to work without installing a coarse filter. The hot water supply system carries with it a large amount of debris and dirt.
3. High temperatures cause hoses to break and gaskets to crack.

A positive aspect is the reduction in energy consumption required to heat water.

Increasing the service life of the device

In order for the dishwasher to work normally throughout the warranty period, it must be used only in normal mode. If, after connecting hot water, the device fails, the warranty may be void. In other words, using one and a half kilowatts during heating can be much cheaper.

When cold water is connected, special salt is added to increase its softness. If the temperature regime is not observed, the existing control system very quickly becomes unusable.

Effect on dishwashing quality

In principle, the quality of dishwashing remains unchanged. The dishwasher is equipped with a special thermostat, which is responsible for heating the water. It allows you to heat the liquid only to a certain temperature. Of course, the speed of the process will become much faster, since there will be no need to heat the water. Therefore, whether such a connection is worth creating remains a controversial issue.

Most people still have a rather wary attitude towards dishwashers - is it worth purchasing expensive equipment if washing dishes, in principle, is easy and done by hand. However, if we recall the very recent past, then approximately the same thing was said about automatic “washing machines”, about food processors, even about televisions at the dawn of the appearance of remote controls, and now it is difficult to imagine normal life without it. You get used to something good and convenient quickly, so many owners who have already installed a dishwasher in their kitchen will never want to lose such “convenience.”

Others follow their example, and dishwashers are increasingly becoming an attribute of the modern kitchen. However, this is not at all the type of household appliance that you can simply unpack, plug in and start using right away. In addition to the rather complex electromechanical “filling” and automation, such a device, to a certain extent, of course, is also a plumbing fixture. Therefore, it is extremely important to correctly connect the dishwasher to the water supply and sewerage system. “Amateur activity” in this matter is not welcome - you will have to comply with a number of certain requirements. Let's try to understand this in more detail.

It must be assumed that if the owners decide to buy a dishwasher, then they have already thought out in advance where it will be installed. In general terms, it depends on which model is more to your liking – compact tabletop or built into kitchen furniture. Accordingly, there may be serious differences in the installation and connection of the device to communications.

In both cases, they try to place the machine as close as possible to the kitchen sink area. This can be explained simply - it becomes possible to connect the device to utilities without resorting to the complex procedure of cutting into pipes - those connections and assemblies that ensure the supply of water to the mixer and its drainage from the sink to the sewer will be quite sufficient. Lengthening the standard hoses of the dishwasher, especially the drain hose, is not recommended, since the capabilities of the sump pump are limited, and you should not overload it so as not to cause rapid wear.

However, such placement is not a dogma at all - you can place the dishwasher in a more convenient place, from the point of view of the owners, but in such a way that within the radius of the length of the standard hoses there is the possibility of inserting into the corresponding sewers (this example will also be discussed in the publication ), or you will have to think about laying an additional section of such pipes specifically for the purpose of connecting the device.

Of course, a power supply line of the appropriate cross-section must be connected in advance to the future installation location of the dishwasher, and a separate outlet must be installed, always with a grounding circuit. The use of extension cords should be completely avoided. Water, high humidity and electricity are already quite a dangerous “neighborhood”, so no connivance like: “Petya has it connected like that - and it’s no big deal” is absolutely unacceptable.

Kitchen power supply is a matter of great importance!

The distinctive features of any kitchen are not only the high level of humidity and constant use of water, but also, perhaps, the highest power consumption of the electrical appliances installed in it. Refrigerator, microwave, washing machine and dishwasher, extractor hood, electric stove and oven, and that’s not even counting the lighting and small household appliances! How to properly organize the power supply to the kitchen is described in detail in the article on our portal dedicated to.

The installation site must be prepared - there must be an appropriate niche for inserting the required dimensions or free space on the countertop for desktop installation. The base must ensure a reliable position of the device, in a strictly horizontal position, supported by all stands to avoid play or increased vibration. Each model of dishwasher has its own requirements for site preparation; the technical documentation provides a description of the installation; the kit usually includes all the necessary fasteners.

There is one more nuance in preparing to install the machine - it must be taken into account in advance. Many models on the back of the case have power cable and hose outlets offset to one side. Thus, the permissible distance to the connection points may be different on the left and right of the dishwasher. Usually this feature is also indicated by the manufacturer in the technical documentation.

Before undertaking the independent installation of a dishwasher, the owner must carefully assess his capabilities and skills. If you have any doubts about your own abilities, it is better to invite an experienced master plumber who has positive recommendations (a considerable number of outspoken “schemers” work in this field). The fact is that violation of installation rules may well lead to termination of the manufacturer’s warranty. Often, large showrooms practice branded installation at a low price, and sometimes even completely free, as one of the ways to stimulate consumer activity. This question should be clarified immediately upon purchase.

In the case when such a service is not provided, and calling a specialist seems to be a significant extra cost, then there is nothing impossible in installing it yourself. And if we “take out of the brackets” the already mentioned power supply line and the features of installing the device in a niche, then the main stage of the process becomes the correct connection of the dishwasher to the water supply and sewerage system.

Sequence of stages, and is there always a need for a fixed connection

These steps can be carried out in any order. By and large, more difficulties will come from preparing for connection - installing all the elements necessary for this. And, in fact, connecting the hoses coming out of the dishwasher with the water supply and sewerage will be the final step, which is performed almost simultaneously, along with the final installation of the device in place.

We can immediately make a reservation about one point. Tabletop dishwashers, in principle, can sometimes do without a permanent connection to communications. In this case, the water supply hose is connected directly to the spout (there are special adapters for this), and the drain hose is lowered and fixed in the sink bowl.

Dishwasher

Sometimes such a scheme is presented almost as an outstanding advantage - they say, the owners have the opportunity to economically use the space of the countertop, taking the dishwasher out of storage and installing it only as needed.

Let me disagree with these “advantages”:

• First, it is unlikely that owners will be found who will carry massive equipment back and forth. It’s just inconvenient, and it won’t do any good for an expensive device. But to use a dishwasher from time to time, “on holidays” - so why buy it at all? It should become a faithful assistant in the kitchen, and not at all a source of “secret pride” for its owners.
• Secondly, from frequent connections and disconnections of the water supply hose, not a single connection will last long - neither threaded nor socket. This is not very good for either - extra loads on the spout loosen it.
• Third, a dishwasher drain hose lowered into the sink bowl poses a certain danger. Careless movement, sudden pressure, childish prank - all this can lead to the hose jumping out of the sink with all the ensuing (literally) consequences.
• And fourth, it’s just inconvenient. By simplifying their work during the initial installation of the device, the owners significantly complicate its further operation. The operation of the dishwasher will require constant monitoring, and in addition, while the washing process is in progress, the kitchen sink, which may be needed at this time for other needs, is practically “paralyzed.”

So, the best solution would still be a permanent connection to the water supply and sewerage system, regardless of the type of model. Moreover, there is no noticeable difference in the order in which the work is performed.

Connecting the dishwasher to the water supply

Let's start by connecting the water supply.

To begin with, a small remark. There is an opinion that, in order to save money, it is more profitable to connect the dishwasher to a hot water supply pipe, they say, expensive electricity will not be consumed to heat the water to the temperature required by the washing program.

Indeed, some dishwasher models support this option. Moreover, there are even machines that provide for connection to two mains simultaneously - cold and hot water supply.

All this must be indicated in the product passport. It is prohibited to connect the machine to hot water unless this option is specified by the manufacturer. The electronics of the device may not understand this, and such amateur activity often ends in the “crash” of the programmed dishwashing algorithms.

But even if such an opportunity to choose between hot and cold water supply is given, almost all the experts unanimously recommend not to experiment, and limit yourself to a regular connection to cold water. There are a number of logical explanations for this.

— Firstly, the quality of hot water is often far from ideal.

- Secondly, it happens that the temperature of the water in the hot water supply exceeds the required heating level set for the dishwasher. It seems to be no big deal, but this again can “mislead” the software control unit of the device.

— Thirdly, it’s no secret that problems with the supply of hot water occur many times more often than with cold water, and in the summer, during the period of repair and maintenance work in boiler houses, there may generally be long outages. It turns out that in such situations you will have to switch to hand washing dishes or urgently switch to cold supply. Isn't it too much trouble?

— And fourthly, in matters of economy, everything is also not so obvious. Modern dishwashers of class A and higher are distinguished by very rational consumption of both water and electricity, and should not “break a hole” in the budget due to electricity bills. On the other hand, if the apartment is equipped with water meters, then the water consumption for washing dishes will have to be paid at the “hot” tariff, which is also quite high.

It’s up to the owner to decide, of course, but good advice is to connect to cold water.

Now, actually, about the connection itself. There may be several options here.

A. The simplest solution is when the installation location of the dishwasher and the length of its hoses provide the possibility of connecting to a pipe to which a flexible hose is connected to the kitchen

To do this, the only tools you will need are an adjustable wrench, a sealing winder, and you will need to purchase a special through-tee with a tap designed specifically for such purposes.

Such a tee has a ½-inch “female” thread for packing onto the water supply pipe (item 1), and on the opposite edge has a ½-inch “male” thread (item 2) for reconnecting the flexible connection of the mixer, that is, it provides a through passage of water. The side outlet is equipped with a ¾-inch threaded part (item 3), ideal for connecting dishwasher or washing machine hoses. The tap (item 4) makes it possible to open and close the water supply in this direction as needed.

Connecting will not be difficult.

• The valve for the general cold water supply to the apartment is closed. Next, you can open any water tap (preferably located closest to the floor level) to relieve excess pressure in the cut-off section of the home water supply.
• Next, using a wrench, unscrew the nut of the flexible mixer connection and release the threaded part of the pipe. If necessary, the remnants of the old winding are removed from it.
• The next step is to wind the sealing winding in the direction of tightening the nut. For these purposes, FUM tape can be used, but a connection sealed with ordinary flax tow and coated with a special “Unipak” paste is more reliable.

• The tee is tightly screwed onto the wound thread. When tightening, make sure that the side outlet with the tap is in a convenient position for connecting the dishwasher hose.

Here we can immediately note one important point. Many modern dishwashers are equipped with an “aqua-stop” system, which has a solenoid valve that will instantly shut off the water supply to the hose if there are signs of a leak (pressure drop). The body of this valve is quite large in size, and is located exactly on the side of the hose that connects to the water pipe.

This means that both when preparing for work, and specifically when installing the tee, it is necessary to take into account how this “aqua-stop” block will fit and whether there will be enough space for it.

• After the tee is installed, you can immediately install the flexible connection of the kitchen faucet in a new place, changing the rubber ring gasket if necessary.
• The tap on the tee is moved to the “closed” position, and after that you can open the general water supply - you will immediately be able to check the assembly for leaks, and, if necessary, carry out a tightening.

• The last step is to screw on the plastic nut of the dishwasher hose. It has its own O-ring and no winding is required. Twisting is done without the use of any tool - just a well-applied hand force.

At this point, in fact, the option of connecting to the water supply directly under the kitchen sink can be considered completed. But it is worth paying attention to one more nuance.

Using a tee circuit will be convenient if one additional water collection point is connected. However, in practice, the space under the sink is often much more crowded. For example, hoses from a washing machine and dishwasher can be connected here, drinking water can be installed, and a flow-through water heater (column) or boiler is often connected.

Under such conditions, the tee system does not justify itself - a complex and heavy structure of tees and adapters is formed under the sink, surrounded by a “web” of hoses and flexible connections, which creates considerable difficulties both for control and for carrying out any preventive or repair work. It will be much more convenient to install a small collector from below, with 4-5 outlets, connect it to a water pipe, and from there make switching to all water collection points.

Such a collector can be purchased ready-made - metal or polypropylene. For those who have at their disposal a machine for welding PP pipes, it will not be difficult to very quickly make a manifold of the desired configuration from polypropylene tees - this is often even more profitable.

Dishwasher

In this case, to connect the dishwasher, you no longer purchase a pass-through tee, but an adapter with a tap.

The collector can be easily secured securely to the wall surface (with clamps or dowels), and all branched switching in the space under the sink will take on an organized appearance. In addition, the interdependence of connected devices operating simultaneously will be reduced to a minimum - with a tee circuit, the opening of water at one water collection point usually entails a drop in pressure at others.

B. The second option is that the length of the hoses to the sink is not enough, extending them is impractical or impossible due to the peculiarities of the arrangement of kitchen furniture, but a cold water supply pipe runs near the installation site of the dishwasher.

The principle is simple - after shutting off the water, you need to cut out a small section of the pipe and install a tee in its place. The tap already mentioned above is sealed to the perpendicular outlet of the tee, and the dishwasher hose is connected to it.

The execution of such alterations depends on the material of the pipe.

• If it is a metal-plastic pipe, then there is no difficulty. A fragment is cut out, and in its place a tee with press fittings is installed, for packing which a set of wrenches is enough. Next, install the tap with conventional winding - and the unit is ready to connect the device.

• It is not much more difficult to cut into a polypropylene pipe, although this will require a special welding machine. Of course, purchasing it because of three or four joints is unprofitable, but usually such a device is easy to rent for a day or two, it is not so expensive.

A welding machine for polypropylene pipes is a reliable home assistant.

To be honest, it never hurts to have your own inexpensive equipment for welding polypropylene pipes - it can bulge in various situations and will allow you to easily and cheaply upgrade home communications. How to do it right - in a special publication on our portal. And another article will help you learn easily and quickly.

When welding polypropylene on a section that has already been installed previously, a certain amount of play in the pipe is necessary so that it is possible to insert mating parts into the soldering iron from both sides. This is not always possible, so it is easier to resort to welding two American union nuts, and between them already mark a regular brass tee with a tap sealed on it for connecting the dishwasher hose.

fum tape

• The hardest part will be if you need to cut into a steel pipe.

— You can cut out a section, cut threads on the remaining ends, and then mount a tee from it, either according to the driving principle, or also using “American” ones. The disadvantage is that it is difficult to cut threads, since a special tool is required.

— Another option is to install a so-called repair clip (bandage tee).

This product allows you to cut into a steel pipe in almost any convenient place on a straight section. The clip with rubber seals is installed on the pipe in the desired position and tightened tightly with bolts. Then the pipe wall is carefully drilled through the tee hole. Next, everything is simple - packing the faucet and connecting the hose as usual.

The method is quite simple, but, to be honest, it is not particularly praised. First, the pipe body is weakened. Secondly, there are known cases of leaks starting in this particular place, and eliminating them will be very difficult. And thirdly, the hole drilled in the pipe often becomes a vulnerable point from the point of view of the formation of blockages.

IN. Finally, the third option is when the dishwasher is located far from the cold water supply pipe.

Increasing the length of hoses means increasing the vulnerability of communications to possible leaks - any flexible line is still less reliable than a stationary high-quality pipe. This means that it is necessary to lead the water to the machine.

Laying an additional section of water supply to the installation site of the device is usually not difficult, and it will require little money. Another thing is how convenient it will be, and how beautiful it will be. If the pipe is completely hidden behind pieces of kitchen furniture, there are no questions.

But it is best, of course, to think through all the issues of future installation in advance, that is, when installing a home water supply and sewer system, immediately provide connection points for household appliances. The ideal option is hidden pipe laying with installation of water outlets on the walls in the right places.

Connecting the dishwasher to the sewer

You can find a lot of articles that claim that connecting a dishwasher to a sewer is generally a simple operation that does not require compliance with any rules. They say that the drainage hose of the device is installed through a sealing rubber coupling into a 50 mm socket of a sewer pipe specially prepared for it - and this issue is resolved. Alas, not everything is so simple, and followers of this technique may well encounter very unpleasant moments.

Firstly, a water seal must be a prerequisite, otherwise unpleasant odors from the sewer will penetrate through the hose into the dishwasher.

Secondly, you should be careful about the backflow of water from the sewer into the machine. To do this, the upper loop of the drainage hose must be located no less than 400÷500 mm from the floor level. Where did these values ​​come from? Apparently, the level of the filled bathtub is taken into account - with a sudden release of water and some temporary problems with the permeability of the sewer pipe, the water in it, according to the physical law of communicating vessels, will tend to rise to the general current level. A looped bend at the right height will prevent it from entering the dishwasher.

Third, directly inserting the drain hose into the sewer pipe using a seal makes this connection virtually airtight. Oddly enough, in this case this is not at all an advantage. Ideally, the pressure in sewer pipes should be equalized with atmospheric pressure so that areas of vacuum are not created. Otherwise, this may result in the so-called “siphon effect” - a massive discharge of water in one of the areas causes a spontaneous flow of water in others connected to it. This leads to the fact that the pipe itself begins to “suck” water from the dishwasher. This phenomenon can cause unbalance of automation, the appearance of software errors and even equipment failure. By the way, the opposite option cannot be completely ruled out - throwing dirty waste into the car, the consequences of which you don’t even want to think about.

But on the other hand, a leaky connection between the hose and pipe means the possibility of leakage and the spread of unpleasant odors. How to do the right thing.

There are several acceptable options:

• One of the simplest, most inexpensive and effective is to install a drain siphon on the kitchen sink with a special pipe for connecting the drainage hoses of household appliances.

As can be seen from the illustration, the siphon can have two pipes - if there is a need to connect both the washing machine and

The pipe usually ends in a conical fitting, the raised, stepped surface of which ensures reliable fixation of the hose after tightening the clamp.

adapter with tap

This connection of the drainage hose, in principle, meets all of the above requirements:

— The water seal against the spread of odors from the sewer is ensured by the design of the kitchen siphon itself.

— The connection point is located at the top; the upper bend of the drainage channel itself is formed.

— At the same time, the drainage hose is not tightly connected to the sewer pipe - it communicates with the atmosphere through the drain hole of the sink. That is, the siphon effect is completely eliminated.

• The above method is very good, but, alas, not always possible. For example, the sink is located out of reach of the dishwasher drain hose, and a section of the sewer pipe has to be pulled through. Another example is that the design of the sink itself and its “branded” drain do not require any changes, and such a connection becomes impossible.

There is nothing to do, you will have to connect to the sewer pipe. If its outlet is already occupied by a corrugated pipe from the sink, it’s okay, you can install an “oblique” tee, reconnect the siphon, and use the second outlet for the dishwasher. And the connection here, whatever one may say, will still have to be made airtight, using a sealing rubber coupling, otherwise an unpleasant odor cannot be avoided.

But what then about the rest of the connection requirements?

The easiest way to solve the issue is to provide a water seal and ensure the required loop height. You can purchase a special polymer insert (they are often even included in the equipment supply), fix it in the intended place on the wall, and fix the hose in it at the desired height. In this case, it is necessary to ensure that the hose is positioned in such a way that a lower bend is created (like the letter S) - it will serve as a water seal.

But what about the potential threat of the “siphon effect”? There are also ready-made solutions for this.

— Installation of a simple “anti-siphon” valve on the hose.

This product is inexpensive and very easy to install. The hose is cut and then connected through this valve, covered with clamps. The disadvantage of the simplest device is its short service life, usually not exceeding six months. After this, you will have to purchase a new valve, since it is practically impossible to maintain.

— A more reasonable option is to purchase an “anti-siphon” valve, made in the form of a loop. Not only does this immediately solve all the problems of proper hose placement, but such devices are completely subject to regular cleaning, which means they will last much longer.

A slightly more expensive and complex solution, but extremely convenient to use and meeting absolutely all requirements, is the installation of a special wall siphon for a dishwasher (washing machine). They come in wall-mounted or hidden versions, with varying degrees of decorativeness, but they are united by the presence of all the necessary valve devices that ensure comprehensive safety of connecting the device to the sewer.

The rear wide pipe is hermetically connected to a vertical branch of a 50 mm sewer pipe, and the dishwasher drain hose is connected to the front pipe. In fact, it turns out to be a kind of analogue of a water outlet, only for the exact opposite purpose. They are usually replaced side by side, creating a special switching zone for the device.

Moreover, if you want to give such a connection unit an external “impressiveness,” you can purchase an entire console structure, which includes a drain siphon with all the valves, a water outlet with a tap, and even a power outlet. Such devices are usually equipped with decorative facade plates - both beautiful and with everything needed for connection at a glance.

And finally, we can mention another very interesting technological solution. Some manufacturers equip their models with a special valve that provides the necessary air gap to eliminate negative impacts from the sewer system. The design approach itself is interesting - the valve cuts into the surface of the countertop or the back horizontal panel of the kitchen sink.

Such a valve is placed in a place where it will not interfere, and covered with a decorative cap on top. From time to time it will require preventive maintenance, but removing the cap and cleaning will not be difficult.

So, various options for connecting the dishwasher to the water supply and sewerage system were considered. Some of them are completely simple, others will require certain knowledge and skills. However, none of them can be said to be completely inaccessible for independent execution.
