How to properly connect a dishwasher with your own hands

 The dishwasher is an amazing invention that makes the work of every housewife in the kitchen easier. Designed for washing and rinsing spoons and plates in automatic mode - the dishwasher removes the eternal dispute: - "Who should wash the dishes today?" But after purchasing a kitchen assistant, the question of connecting it immediately arises. Today we will talk about how to connect a dishwasher with your own hands.

Types of dishwashers

Among the variety of dishwashers, there are two main types:

  • portable;
  • stationary.

Portable dishwashers are installed on any flat surface near the sink, plugged into a socket with a protective ground, the water supply hose is connected to the tap, and the drain hose is placed in the sink. After finishing work, such a machine, as a rule, is removed to a specially designated storage space.

Stationary dishwashers are installed in the immediate vicinity of the water supply and drainage points for their permanent location. This is the most common type of dishwasher , which requires a more careful approach to the issue of their connection. The inclusion of this type of dishwasher in the electrical network is carried out with a protective ground.

Choosing a location

Even before purchasing a dishwasher, you need to choose a place to install it. A socket with protective grounding, points for water supply and drainage should be nearby (the distance from them should not exceed one and a half meters). If there is no socket with protective grounding in the place of the proposed installation, then it must be installed.

Important! Installation of electrical wiring and sockets must be carried out in accordance with the "Electrical Installation Rules" and other norms and rules. For strict compliance with them and to prevent the possibility of electric shock, it is better to entrust this stage of connecting the dishwasher to qualified specialists.

When the place is selected, all the connection points are available - you can proceed directly to connecting a stationary dishwasher with your own hands.

Preparing the installation site

Many kitchen sets have a niche for installing a dishwasher . The passport for furniture usually indicates the models of dishwashers that can be installed in this set. The fact is that not all dishwasher manufacturers adhere to standard sizes and mounting options.

Before buying a dishwasher, carefully measure the width, height and depth at the installation site and check them with the dimensions indicated in the passport of the purchased product (there should be a small margin for installation). Reposition the mounting plates if necessary.

When installing Bosch dishwashers, this type of problem usually does not arise. This company manufactures its products in accordance with the specifications of many furniture manufacturers.

Important! Do not place the dishwasher under the hob. This neighborhood can lead to failure of one or another product.

What is required to install a dishwasher

The durability of its service, the safety of others and the safety of property depend on the quality of the work carried out on the installation of the dishwasher. To carry out an independent installation of the dishwasher, we need:

  1. electric drill;
  2. stationery knife;
  3. pliers and adjustable wrench;
  4. small building level;
  5. ball valve;
  6. water tee;
  7. waterproofing tape (fumka);
  8. siphon.

Dishwasher connection steps

In terms of their functionality, dishwashers resemble washing machines . For their smooth functioning, you need: electricity, water supply and connection to the sewage system. The presence or installation by professionals of a new euro socket with grounding solves the issue of power supply.

The plumbing part of the work remains, which must be started by connecting the drain hose to the sewage system. This sequence is necessary to facilitate self-connecting the machine.

We connect to the sewer

The drain hose of the dishwasher should be connected to the drainage system via a siphon to avoid unpleasant odors. The length of the drain hose should not exceed one and a half meters, otherwise the pump responsible for draining the waste water will overload and quickly fail. For the same reason, the connection of the drain hose must be made at an angle to the drain, so that the dirty water flows by gravity for most of the way. Directly at the junction of the hose with the siphon, on the contrary, it is necessary to create an upper bend to prevent waste water from entering the sink into the drain system of the dishwasher. It is advisable to fix the junction with a clamp.

We connect to the water

Depending on the model, dishwashers are connected to both cold and hot water supply systems. The connection process in both cases is identical.

Important! When choosing a dishwasher, you should take into account that the quality of hot water in most settlements is very far from ideal. The water is usually not very clean, with unpleasant odors . This can subsequently adversely affect the quality of dishwashing and the durability of the kitchen appliance itself.

To independently connect to the water supply network, it is necessary to shut off the water supply to the apartment, open the taps and drain its residues from the system. Then, using an adjustable wrench, unscrew the union nut and disconnect the flexible mixer hose at the point of its connection to the pipe.

Thoroughly clean the thread from dirt and old waterproofing, wind a new fumka on it clockwise (the number of turns depends on the thickness of the FUM tape, usually 5-6 is enough). Screw on the tee for branching the water flow, carefully stretch it with an adjustable wrench . Attach the previously removed flexible mixer hose to one of the ends of the tee, and screw the ball valve onto the other. Connect the dishwasher inlet hose directly to the tap. We do not forget to stretch all threaded connections well and wind up with a fum.


The presence of a shut-off valve in the water supply system allows you to stop the water supply to the installation in the event of a long absence of the owners or the threat of flooding. This option is recommended even on dishwashers with leakage protection installed.

It is also recommended to supply the water poured into the machine through the flow filter, which is installed between the tee and the ball valve . Dishwashers from leading manufacturers, such as Bosch, famous for the quality of their products, are very demanding on the purity of the supplied water. Therefore, it is recommended to install the filter even if the water source is an artesian well.

When all the necessary equipment is installed, the last hose is screwed on - the dishwasher is considered connected to the communications. It remains only to check it and install it correctly at its permanent location. If you still have any questions about the connection, then watch the video on installing the Bosch dishwasher:

Checking before installation

We turn on the dishwasher in the electrical network, open the shut-off valve on the water supply. We check the car for leaks in threaded connections. We start the dishwashing cycle, control the water supply to the chamber. It is advisable to wait until the end of the dishwashing cycle for a more complete picture . During the work process, we continue to monitor the water supply, its discharge, and identify possible leaks. At the end of the work, we de-energize the dishwasher, eliminate any faults found.

The question of checking the dishwasher before installing it must be taken with full responsibility. This will allow in the future to avoid emergencies with her participation, unnecessary material costs and nerves.

Installing the dishwasher

The installation process must be carried out very carefully. It is advisable to temporarily free the space at the installation site from furniture, to provide free passage and access to the washing machine. When installing in a niche, do not bend the drain and inlet hoses or violate their integrity. Excess hose lengths formed during the movement of the device must be pulled out in time to the connection point so that they do not interfere with the installation.

After installing the device at its permanent location, we adjust the position of its body at the building level. To do this, we put it on the dishwasher lid and by adjusting the legs we achieve the level in the horizontal plane.

After setting the dishwasher to a level, carefully fix it to the mounting plates, hang the decorative facade - the kitchen assistant is ready to go! We recommend that you watch the video on installing the Bosch dishwasher to consolidate the information received:
