How to connect a dishwasher to communications

The dishwasher installed in the kitchen makes the life of the owners much easier. With the help of it, dirty dishes are cleaned. Its correct operation largely depends on how competently the connection to communications was performed. In order to answer the question of how to connect a dishwasher, you need to familiarize yourself with the step-by-step algorithm of work, as well as focus on some important points.

What tools and materials are used to connect the dishwasher

There is an unchanging list of inventory required for the competent integration of the device and its connection to all communications. Without the appropriate tools and materials, the connection will not work correctly. Therefore, we will consider this list in more detail:

• adjustable wrench;

• pipe wrench;
• screwdrivers (flat and cross);
• pipe cutting tool;
• countersink;
• building level;
• electric drill;
• copper pipe;
• fitting.

Countersink is used to remove burrs that form when cutting pipes. The level must be prepared short (40 cm). It is worth purchasing the appropriate attachments for the drill. To connect the dishwasher, feather drills of different diameters (15, 22, 50 mm) are used. A copper pipe is required to supply water to the unit. Fittings are used to join pipes together. The dishwasher is connected using collet nuts.

Note! The dishwasher kit includes a flexible hose. With the help of it, a connection to the water supply is made. If you use this element, then there is no need to purchase pipes and fittings.

Some PMM models are connected to communications in a completely different way. These devices include a tabletop dishwasher. The connection of such a device is performed using an external method.

Also, the connection to the water can be made using metal-plastic pipes. Of the additional tools, it is worth highlighting a water supply corner equipped with a ball valve that performs a shut-off function. Its installation allows you to instantly disconnect the PMM from the water supply system.

Installing and connecting the dishwasher: stages

To connect the dishwasher, you will need to bring it to the cold plumbing system and sewer system. You will also need to connect the device to the mains. Such work requires certain knowledge and skills, so it is necessary to study the entire algorithm of actions.

If you wish, you can use the services of an experienced master. The price of connecting a dishwasher is quite reasonable. The most expedient solution is to install the unit in the lower cabinet of the kitchen unit (under the countertop). Let's consider the sequence of work in more detail.

The first stage in the installation of the PMM is to connect to the water supply system. Most often, there is a special branch on the pipe, which belongs to cold water supply. It must be connected to the hose that comes with the dishwasher.

When purchasing a PMM, it is strongly recommended to check the length of the hose, since the baseline may not be enough. This is especially true in cases where the unit location is not standard. Choosing the length of the dishwasher hose is a very important point that should not be ignored.

The second stage of connection is the supply of the device to the sewer system. You will need to connect a special drain hose to this communication. It is worth remembering that the connection must be made in such a way that no leakage occurs during operation. To do this, you need to seal the junction with special materials (linen thread or FUM tape). This will allow the dishwasher to be connected correctly.

At the third stage, the most important work is done. For comfortable operation of the device, you will need to install a separate outlet, since the power of the PMM is quite large. In addition to an independent power line, you will also need to equip the dishwasher with grounding, which is necessary to eliminate the threat of electric shock.

Useful information! Experienced craftsmen recommend installing a special switch in the dishwasher outlet. This element is responsible for the emergency disconnection of the device from the power supply. This is most often caused by power surges in the network.

The last step in the connection is to check the work that was done earlier. You will need to perform a test run of the dishwasher. The first test is carried out without dishes, however, detergent should still be added to rinse the inside of the device.

The importance of grounding electrical wiring

The dishwasher is considered one of the most dangerous devices in terms of electrical safety. This requires the wizard making the connection to take all necessary security measures. The unit is grounded first of all when connected to the mains.

The grounding must be serviceable, so you should be serious about installing it, which will make the dishwasher safe. It is quite easy to connect the ground. The work is carried out according to standard technology.

Quite often, inexperienced people make one mistake, namely, they make a zeroing during the installation of the PMM. The essence of this false step is that in the absence of electrical protection, the grounding contact of the socket is connected to the working zero. Such an error can lead to a dangerous potential that will pass through the housing of the unit. This can happen if the neutral wire breaks.

It is recommended to avoid such mistakes. Bosch and Electrolux dishwashers are very sensitive to electrical surges and other problems associated with installation and connection. To avoid problems, it is recommended to study the diagrams that depict the nuances of putting the PMM into operation.

In order to avoid the occurrence of phase voltage in the mains (dangerous potential), the work must be done correctly. But the most dangerous situation, of course, is the complete absence of grounding. Before starting work, it is recommended that you study a video that clearly explains how to connect a dishwasher at home.

The machine must be well insulated so that the hazardous potential resulting from an emergency is not transferred to the water. Thus, connecting the PMM to the electrical network is a very important point, which determines how safe the operation of the device will be.

Electrical connection: wiring requirements

To make sure that the electrical wiring is suitable for connecting the PMM, it is necessary to perform a correct assessment of its condition. The main thing to find out is whether there is enough load capacity to feed such a powerful technique. In the event of a shortage of it, an emergency may occur.

How do I connect my Bosch dishwasher to the mains? Experts advise using sockets that are powered by an individual wiring line. Such a line must be directly connected to the electrical panel. It is recommended to connect a circuit breaker to it, as well as a device responsible for turning off the power in case of an emergency.

If there is a free outlet in the kitchen related to the group wiring, it is necessary to check whether it can withstand the load when the dishwasher is connected. The total capacity must not be exceeded, otherwise an emergency will occur. For such work, it is best to use the services of a qualified master. The cost of connecting a dishwasher can range from 500 to 1500 rubles.

Note!The power of dishwashers belonging to the household group usually does not exceed 2500 watts. This means that a standard socket is suitable for connecting such a device, which is suitable for electrical appliances up to 3500 W.

You will also need to analyze all electrical appliances in the kitchen. If necessary, you can reconnect devices that create an excessive load to other lines. The electrical wiring must be in good technical condition.

Of course, it is much better to work with new lines, however, this is not always possible. Answering the question of how the dishwasher is connected allows the video, which explains all the subtleties of work.

If the wiring is old, then it may not withstand the connection of new household appliances with similar power. Thus, it is necessary to ensure complete protection of the wiring and adhere to the permissible load values.

Before plugging in the dishwasher, you need to check its technical condition. The plug connectors, as well as the contact clamps, must be in full working order. If a problem is found, it is worth replacing the outlet.

How to connect a dishwasher: choice of wiring

To connect the PMM, it is worth using suitable wiring that will be compatible with the technical characteristics of the device. Most often, a copper wire is used for this purpose, which is marked with PVA 3. Its main advantages are that it has good rigidity, which allows it to keep its shape. Also, such a cord is easy to cut and peel off the insulation.

This wire includes 3 cores. Two of them are phases (0 and 230 V), and one more is used for grounding. Each of the veins has an individual color, which allows the technician to navigate while connecting the dishwasher. It is possible to perform such an operation with your own hands, but you should correctly assess your own capabilities.

The power of such a cable entirely depends on the cross-section of the conductors. The operating voltage of PVA 3, as a rule, is fixed at around 380 V. If a desktop unit is connected (in parallel with the refrigerator), then it is worth choosing a thicker cord, since thin options may not withstand such operating conditions.

If it is not possible to connect the dishwasher to a separate power line, then it is recommended not to use devices powered from the same outlet at the same time.

Connecting the dishwasher to the mains: installing the socket

Let's consider how to carry out the correct installation of the socket under the PMM. In no case is it recommended to use an extension cord to connect a dishwasher, as this type of appliance may not withstand high loads and fail. In extreme situations, the extension cord may melt.

To connect a Bosch dishwasher, in any case, you must purchase a separate device with good electrical resistance. It is recommended that you purchase a grounded outlet. It is desirable that it has good moisture resistance. When installing electrical devices in the kitchen, the last point is very important, since there is an increased level of humidity in this room.

Features of installation. Preparing for installation. Dishwasher sizes. Mounting options. Installation technology for built-in PMM.

In order to carry out the prompt installation of the socket for the PMM, it is necessary to prepare a three-core wire and the device itself. Next, you need to remove the insulating material from the ends of the cores and connect them to the terminals. It is very important that the wires are firmly clamped in the terminals. For secure fixation, bolts are used, which must be tightened.

Note! The socket box must be mounted at a certain distance from the floor. The minimum allowable distance to the coating in this case is 15 cm. Otherwise, it will not be possible to ensure the proper operational safety of the device. Dishwashers Bosch20 (or any other) belonging to the free-standing class are usually connected to sockets located at a height of 40 to 90 cm.

The main thing is to position the device correctly in height. The dishwasher needs to be grounded. It is quite easy to identify the wire that is responsible for this protective function, since all the wires are color-coded. In this case, the insulating surface will have a yellow-green tint. This wire is connected to a separate terminal. Installing an outlet is a fairly simple event, but if there is no self-confidence, then it is better not to risk it. A specialist will carry out this work quickly and reliably.

The wire that supplies electrical current to the outlet runs to the junction box. It must be equipped with a separate circuit breaker. Separate line wiring eliminates the possibility of overloading the device due to high power. The dishwasher is not the only household appliance for which a separate line is recommended. Experts advise you to perform this procedure for all powerful devices located in the kitchen.

After installing the socket, it is recommended to check it for operability. To do this, it is enough to turn on the circuit breaker and plug any electrical appliance into the outlet.

Saving electricity when installing PMM

Most of the electricity consumed by the dishwasher goes to heating the water. There is a way to avoid excessive costs. This method is quite popular and involves connecting the PMM directly to the water supply system transporting hot water.

Many people wonder if this connection option will help save money. In such a situation, it all depends on the method of obtaining hot water. If a boiler is installed in the house, then its use can increase financial costs. You will need to compare how much electricity both devices consume and choose the most economical option.

Useful information! Built-in dishwashers and free-standing units can be connected directly to the hot water supply. This takes into account the consumption of cubic meters of liquid. If the cost of paying for water consumption is lower than the price of electricity, then you can use this method.

It is also possible to heat water by means of a gas column. This technology, as a rule, is less expensive, so it suits perfectly for economy. Before starting work, it is recommended to study the corresponding video. Do-it-yourself dishwasher connection is carried out taking into account safety rules. The outlet should not be too close to water and gas sources, and it is also worth monitoring the absence of voltage in the network when installing such an electrical appliance.

Connecting the dishwasher to the water supply and sewerage system

The correct connection of the PMM to the water supply system and the sewerage system is carried out step by step and requires certain knowledge and skills from the master. The dishwasher hose is most often connected to the cold water supply. In this case, the heating of the water is carried out by the device itself. Docking is done using the dishwasher inlet hose.

Experienced craftsmen recommend installing a filter device, which is necessary to reduce the hardness of the water. This will increase the operational life of the PMM. If you neglect this condition, then the unit will quickly fail. Water with an increased hardness index leads to breakage of the check valve. As a result, dishes that have passed the washing procedure acquire an unpleasant odor.

Connecting built-in dishwashers and freestanding devices is carried out in several stages. Of course, the correct installation of the appliance is very important. Efficiency will depend on its location, therefore the masters recommend equipping a niche for PMM in the immediate vicinity of the sink. Consider the main stages of connecting the PMM to a cold water supply system.

The first thing to do is turn off the water. To do this, you need to turn the shut-off valve, which is most often located in the kitchen. Do not forget that you will need to turn on the tap later. A variety of fittings can be used for the dishwasher. Next, it is necessary to dismantle the hose docked with the mixer. The next step is to install the tee on the pipe.

Then the tee is docked with the mixer. Thus, an additional branch is obtained, which is necessary for the installation of the PMM. A locking device must be installed on the middle pipe. In this case, it is best to use a ball valve. The PMM hose is connected to the outlet of the shut-off element. At the end, all that remains is to install the filter device. It is mounted to the second free branch of the tee.

Note! What is needed to connect a dishwasher is not an easy question, as the tools and materials may differ depending on the specific situation. Features of the location of the PMM and its model affect the installation technology.

The dishwasher package may include a hose that is not long enough for connection. In such a situation, you will need to purchase a longer hose. The use of special transition elements can also help, however, this option is not always appropriate.

Connecting the dishwasher to the water supply (via siphon)

Self-connection of the dishwasher can be done according to a method that takes into account the use of a siphon. This method is quite simple, so it is suitable for beginners. However, this operation should be carried out carefully, adhering to the installation rules. Consider how this kind of work is done in stages.

The dishwasher hose is fixed on the wall or on the wall of the cabinet, which was selected for the installation of the PMM. During fastening, it is worth considering the fact that the hose must be located higher than the drain inlet of the sewer system. The recommended distance is 60 cm.

Further, the hose, fixed in the previous step, must be tilted in such a way as to create a gravity flow of liquid from the dishwasher. This manipulation will prevent the sleeve from getting water from the sink. Further, the drain must be connected to a siphon.

The principle of operation of such a drain is similar to that of washing machines. How to install the drain hose correctly? If there is already a siphon under the sink that does not have taps, which is not intended to be replaced, then you can choose another option for connecting the dishwasher. For example, you can connect the drain hose to a sewer pipe. The connection point must be equipped with a sealing material, the function of which is to prevent leakage.

The dishwasher hose connected to the sewer system will also need to be bent to eliminate the possibility of waste water flowing in the opposite direction.

Before proceeding with the connection of the drain, it is recommended to once again make sure that the length of the hose allows this operation. It is also worth saying that a hose that is too long can also act as a negative circumstance, so this characteristic should clearly fit the specific installation conditions.

How to connect a dishwasher with your own hands: advice from experienced craftsmen

There are several recommendations that allow you to properly install the dishwasher. In no case should you ignore them, as this can lead to errors during this event. For a reliable connection, you will first of all need to take care of installing a filtration device that will prevent the penetration of various foreign particles from the water supply into the PMM.

Useful information! In order for the machine to serve as long as possible, it is not recommended to hot-connect the water to the dishwasher. This is due to the fact that with such a connection, the risk of blocking the unit increases. Hot water most often has a lower quality, which affects the operation of the PMM.

Also, do not bring the dishwasher to a water heater (boiler). In this case, you will not be able to save money, but, on the contrary. In addition, this connection option will affect the water temperature at other points of the water intake. During the operation of the dishwasher, residents will have to use cold water, since hot water will go to the needs of the PMM.

When connecting a dishwasher to a sewer system, it is required to provide for a safety valve that will control the direction of the flow of drains. For this purpose, it is best to purchase a reverse type device.

When connecting the dishwasher drain, you must carefully check the reliability of the joint, since inattentive installation can lead to leakage. During operation, the use of various extension elements must be avoided, as they may not withstand the high power of the device.

The taps used to connect the PMM are recommended to be selected from bronze material. This is due to the fact that polymer analogs have weaker technical characteristics and a short service life. The tap for connecting the dishwasher to the water supply can also be made of brass. Such material will provide high reliability.

These simple guidelines will help you get the job done right. Before starting this operation, it is recommended to study the instructions supplied with the unit. Some device models have design-related features, so the instructions should include tips for installing a specific device.

How to draw up a diagram for connecting a dishwasher to a sewer system

The scheme according to which the dishwasher is connected can be of two types. In the first case, the docking is carried out by means of a special tee. The second option involves the use of a separate siphon, docked with the sewer communication.

Using a tee to connect the dishwasher to the water supply is the most appropriate solution, especially if you are installing without the appropriate experience in this area. To implement this method requires a minimum of labor.

Useful information!The installation of a dishwasher for a summer residence has its own characteristics, for example, to implement this option, you need to provide the device with access to water. Some sites are deprived of this opportunity. But this problem can be solved by connecting the dishwasher to a tank filled with water. Its volume should be sufficient to cover the needs of the dishwasher.

When using a siphon with outlets, there is a protection against the ingress of water back into the dishwasher. Sometimes it happens that there is no possibility of connecting the PMM in the places where the pipes are laid. In such a situation, it is best to take measurements that will determine the shortest route for laying.

The use of a siphon for a dishwasher when installing it requires more care and attention from the master. The installation of such a device should be carried out taking into account the diagram drawn up earlier. It indicates all the components of the structure, as well as their overall characteristics.

When drawing up a diagram, it is worth remembering that the diameter of the pipe that will be supplied to the sewer system must be no less than the size of the pipe. Also, you cannot use pipes to connect PMM, the cross-section of which is higher than that of the sewage itself. It is recommended to select this parameter in such a way as to obtain the optimal drainage speed.

In the diagram, it is also necessary to mark the fixation points for the dishwasher drain. The tube must be secured to the wall. In this case, an internal gasket is not possible. When fixing the pipe, do not make a large number of connections. The optimal spacing for fasteners is 1 m.

Dishwasher: connection to the sewer

It is possible to supply the pipe from the PMM to the sewer communication in different ways. The complexity of the connection is influenced by the amount of free space between the wall and the unit itself. It is recommended to determine this indicator in advance, which will allow you to correctly plan the pipe supply.

Most of the time, there is enough free space. In such a situation, you only need to drill holes for the outlets in the kitchen furniture. But such a possibility does not always exist. If there is a lack of space, then the gasket is carried out inside the cabinet. It is worth choosing a niche with a reserve of space for a dishwasher. When laying the pipe, it is recommended to remove unnecessary boxes that will interfere with the work. For convenience, you can dismantle the front doors.

The field of preparation of the workspace must be marked. It is made with a pencil along the outer ends of the walls of the headset. In this case, it is recommended to focus on the sewer bell. Be sure to take into account the slope of the pipe when performing this operation.

After that, you will need to transfer the markings to the back wall of the kitchen set. This will provide precise contours to match the location of the pipe. Next, you need to use a crown and make holes. When choosing a PMM for a specific cabinet, it is important how correctly the depth of the dishwasher was selected. The complexity of the further laying of pipes and their connection will depend on this.

When docking the dishwasher to the sewer system, it may be necessary to trim the rear of the shelves and drawers. It is not difficult to perform such an operation on your own, but the cuts must be protected with waterproofing, otherwise the humid environment will quickly destroy the wood base.

If you wish, you can refuse this connection option and attach the pipe to the siphon located under the sink. This option is less complicated, but also requires the creation of the correct position of the pipe, which allows you to organize a protective water seal. If, after connecting, there is water in the dishwasher, then the water seal should be redone.

The correct formation of such an air sleeve is especially necessary when connecting high-tech devices from well-known brands (for example, Bosch or Electrolux). Connecting dishwashers of this type requires special care. The nuances of arranging a water seal for a particular model can be found in the instructions attached to it.

Note!It will not work to implement a connection using a solid pipe, since the walls of the sections will interfere with this. It follows from this that before purchasing materials, it is necessary to calculate in advance the length of the constituent elements.

Individual pipes can be joined together by means of special connecting elements - fittings. When connecting, it is not recommended to make sharp turns of the pipeline. Elbows and tees with an angle of 45 degrees are best suited for this work. The use of such connecting elements allows for a rapid drainage of water.

How to connect a dishwasher small size

The instructions that come with the small dishwasher include a description of the installation method, which does not imply a stationary connection to communications. The principle of operation of such small-sized devices is quite simple. Before turning on such a unit, it is necessary to connect the water supply hose to the mixer spout. In turn, the drain hose is lowered into the sink.

This allows dirty dishes to be cleaned without being connected to the water supply. A mini dishwasher is indispensable when you need to wash in the country. Such a device is easy to transport and use, which is why it is quite popular.

Such a small unit also has some negative aspects, which are recommended to be considered. For example, in order to wash dirty dishes, it is necessary to perform unnecessary actions every time. Another disadvantage is the unpresentable appearance, which is spoiled by the external hoses.

It is also worth knowing that with frequent use of such a device, quick wear of the docking places occurs. Using a dishwasher without connecting to a water supply is primarily due to the need, but this option can also be purchased for permanent use in an apartment.

The use of such a unit requires care, since the hose connected to the mixer spout can be disconnected under the influence of a strong liquid pressure. As a result, water will leak. Therefore, it is worth carefully checking how well the temporary connection of the device was performed.

During operation, the dishwasher occupies the sink, which prevents other manipulations from being carried out in it. For the convenience of using such a device, experts recommend choosing a suitable place in which the device will be located on a permanent basis.

Connecting the dishwasher to hot water: peculiarities

When installing PMM, it is recommended to take into account the possibility of implementing a connection to a hot water supply system. Most of these units need to be connected to a cold plumbing system. But the functionality of some models takes into account the use of hot water from communication. To begin with, it is worth reading the instructions, which indicate the various installation nuances.

Useful information! The temperature of hot water transported through the plumbing system should not exceed 60 degrees. Otherwise, an emergency situation may arise. The temperature will damage not only the hoses, but also the internal components of the PMM.

It should be borne in mind that the hot water supply system in apartment buildings is not stable. Therefore, temperature jumps are possible, which negatively affect the condition of the dishwasher. What do you need to properly connect to a hot water system? The set of tools in this case is the same, but there are some differences. For example, you will need to purchase heat-resistant sealing elements.

Connection to hot water supply is most appropriate in a private house, which has autonomous heating, realized by a gas boiler. Such a PMM installation is most often performed in order to save money, since the cost of gas is lower than that of electricity.

Another advantage of this method of connecting the PMM is the ability to regulate the temperature of the water. Some PMM models are equipped with a heat exchanger, which is necessary for drying dishes that have passed the washing procedure. This technology is most often found in Bosch dishwashers. Connecting such devices only to hot water is unacceptable, since they need cold liquid. Before purchasing a device, it is recommended to study the principle of operation of a particular model.

Completing the dishwasher installation

When the supply of communications is completed, you can begin the final stage of integrating the dishwasher into the kitchen set. To begin with, it is worth protecting the countertop from the steam that PMM releases. On the underside of the countertop, you will need to attach a plate made of any suitable material (plastic or metal). It is worth saying that desktop units are not sold with ready-made plates, so if necessary, you will have to do it yourself.

The next stage is the final connection of the PMM to all communications. When connecting the dishwasher to the drain, you need to be especially careful. At the end of the work, it is worth pushing the unit back into place. Next, you need to adjust the vertical position of the machine. For this, its design provides for special legs, which are unscrewed with a thread. This is a very important point, since its operational life depends on how exactly the device stands.

The final steps include the installation of the front part (facade), which performs a protective and decorative function. When installing the front door, you should use a special template that comes with the PMM. In order to avoid mistakes at the final stage, it is recommended to study the video of connecting the dishwasher. It describes in detail all the necessary manipulations, as well as provides valuable recommendations to simplify the work.

This completes the installation of the PMM. In the end, it remains only to carry out a test run of the unit, which will allow you to check how correctly the connection was made. It is quite possible to perform such an operation on your own, because this requires only simple tools and accuracy.

How to turn on the dishwasher

First, it is worth checking whether the device is connected to the mains and open the water supply tap, which was turned off before starting work. Next, you need to inspect the inside of the dishwasher. To do this, rotate the impeller and make sure the filters are in place.

How to use a Bosch dishwasher (or any other)? For a trial run, it is recommended to use a special starter kit, which is not difficult to obtain on the market. First, salt is added to a special tank. It needs to be slightly diluted with water. Then we extract the powder intended for the first launch from the kit and pour it into the appropriate compartment.

Note! Some starter kits do not have the powder used for the test run of the dishwasher. If you purchased an incomplete set, then do not worry, as ordinary powder for PMM will do.

Next, you need to start the unit from a particular company (for example, Bosch). How do I turn on the dishwasher? To activate it, select one of the programs presented in the list on the touch panel. It is recommended to check the device's functionality by running the longest running program. PMM must be empty. Thus, a functional check of the unit is carried out.

The dishwasher has long become a must-have household appliance, which is customarily installed in a kitchen set. Of course, various models have their own design features, however, for this there is an instruction in which such points should be indicated. Everyone can carry out the installation of the PMM, but you should be very careful, especially when it comes to electrical engineering.
