Installing a built-in dishwasher: step-by-step installation instructions

Modern built-in kitchen appliances are designed for do-it-yourself installation, so washing machines, dishwashers, refrigerators and ovens are equipped with detailed instructions, diagrams, templates, and sets of fasteners.

But first you need to prepare the place, pay attention to the issue of supplying communications, and think through every single nuance of connection.

To make it easier for you to understand the rules for installing a dishwasher, in this article we have provided step-by-step instructions, where each stage of work is discussed in detail. With this guide, installing a built-in dishwasher will be quick and easy.

Preliminary work before installation of PMM

There are two options for installing a dishwasher: yourself and with the help of specialists. In the first case, you risk connecting the car incorrectly; in the second, you will have to part with part of the family budget.

Sometimes the skills of one craftsman are not enough; you have to call a team of specialists: a furniture assembler, a plumber and an electrician.

Installation services for built-in equipment are offered by companies that sell them. For a certain fee, a universal master comes at the appointed time, carries out all the connection work and checks the serviceability of the machine.

However, if you carefully study the installation instructions, think about connecting hoses, find or install an additional outlet, you can save money and acquire new skills by doing everything yourself.

Choosing a location based on size

An important step is choosing a location for installation. For the built-in model, furniture modules of the first level are suitable, that is, cabinets standing on the floor.

But if you liked compact mini dishwasher, then its installation is a little easier - such equipment can be inserted at waist or chest level (for ease of maintenance).

There are several conditions for choosing a good location. If they are not followed, you may later encounter problems with water supply/discharge or PMM maintenance.

Many installation difficulties arise when a dishwasher is integrated into an already installed kitchen set. You have to adjust cabinets to fit, and sometimes dismantle and remodel some of the furniture.

We recommend that you take care of the installation location before purchasing furniture. This also applies to other household appliances that require integration. Usually, the models you like are first selected, and when drawing up a sketch of the headset, their location and exact dimensions are taken into account. We have provided recommendations for choosing a built-in dishwasher in this material.

Preparation of tools and materials

Manufacturers of built-in PMMs sometimes list in the instructions what tools may be useful during the installation process. However, they expect that preliminary work has already been done.

If measures are required to lay a power line or tap into a pipe, the list of necessary items will increase.

To be on the safe side and save time, you should stock up on the following tools:

• hammer drill or powerful drill;
• adjustable wrench;
• hammer;
• a set of screwdrivers, including flat and Phillips;
• chisel;
• pliers;
• laser level;
• tape measure, square, pencil;
• screwdriver

In addition to tools, you will need connection parts. It is not recommended to use used elements - this will reduce their service life.

To install a socket, you need to buy the electrical installation product itself, a socket box for it, a three-core copper cable, and an additional automatic protective device.

There are special requirements for the socket: it must be of a “European” type, with grounding, preferably protected from moisture, fully operational, without damage

To connect water you will need a metal tee for inserting into the water supply system, fum tape, water shut-off valve, rubber gaskets, clamps or ties for fastenings.

If the siphon is not provided for connecting another drain hose, then it will also have to be changed.

If the mains voltage frequently fails, we recommend purchasing stabilizer. It can be installed on several devices at once.

Stages of connecting communications

When connecting the dishwasher, it is necessary to prepare an electrical line suitable for the power characteristics.

And also provide a connection point for the hose with the cold water pipe (or mixer outlet), and a hole for the drain hose - it is better not directly into the pipe, but into the siphon, which is located under the sink.

Stage #1 - electrical wiring

To ensure that a dishwasher or other household appliance does not experience interruptions or emergency problems with the power supply, it is necessary to take care of the stability and safety of the entire line, which begins in the electrical panel and ends with the outlet.

The following construction and installation activities may be required:

1. Wall chipping for internal electrical wiring. “Rough” work of this type is carried out using a wall chaser or hammer drill even before installing the kitchen unit.
2. Installation circuit breaker in an electrical panel rated 16A, class “C”.For each powerful unit - boiler, washing machine, dishwasher - it is better to install a separate protective device.
3. Laying copper three-core wire from the electrical panel to the location where the outlet is installed. One of the options is VVGng 3*2.5. This is a non-flammable wire that can withstand loads of up to 3.5 kW.
4. Wall mounting socket box and wire output.
5. Installation sockets, cable connection.

After connecting, be sure to test - turn on the machine, and then use any household appliance to test.

You can do the work of cutting and laying the cable, as well as installing the socket yourself, but to install the machine in the panel you will have to invite an electrician from the management company or another service organization

Instead of one socket, it is allowed to install a block of 2-4 sockets, but so that the total load of all electrical appliances connected to the line corresponds to two important indicators: the cross-section of the VVGng copper cable and the rating of the machine.

Stage #2 - insertion into the water supply system

Connecting the cold water supply is a little more complicated than connecting the drain hose.

A tee should be installed at the outlet of the pipe or at the connection point of the mixer so that water flows simultaneously in two directions - to the dishwasher and the sink faucet.

There is no point in installing two separate parts - a tee and a tap, when there are tees specially designed for dishwashers or washing machines with the ability to cut off water.

If you only need to connect the dishwasher inlet hose, the procedure is as follows:

1. We turn off the water and relieve excess pressure by opening any water-folding mixer.
2. Unscrew the flexible faucet connection from the water pipe or adapter.
3. To make the connection tight, screw fum tape or flax with Unipak paste onto the thread.
4. We mount the tee so that the tap is in a comfortable position.
5. Attach the flexible mixer hose. If the old gasket is worn out, replace it immediately.
6. We check the operation of the tap: turn it off and open the water supply to the kitchen. If a leak appears, tighten the threaded connections or replace the defective product.
7. Attach the drain hose by tightening the union nuts. Before doing this, check that the o-rings are in place.

It is important that the water supply hose is not twisted or kinked, otherwise the dishwashing process will be difficult.

Dishwasher hoses are equipped with Aquastop devices with solenoid valves that prevent leaks. These are large devices, so before connecting you must ensure there is free space to accommodate them

If preparations for connection are made in advance, and you plan to install several household appliances that require water, then it is better to use a collector rather than a tee.

The distributing device (collector) has from 3 to 5 outputs. This is enough to ensure water intake for the PMM, washing machine, water heating boiler and filters.

Stage #3 - drain device

There are several options for integrating a drain hose into a sewer system.

The most successful is to connect the outlet end to the siphon pipe, which is installed under the sink.

An economical and easy way to drain. The hose is connected to the outlet pipe of the sink siphon using a plastic corner adapter and a metal clamp

Not all siphon models are suitable for additional PMM connection. If the water seal is not intended for this, it may be possible to expand it with a separate element with a pipe.

However, the cost of the products is low, so it is better to buy a new device, initially designed for the additional connection of a washing machine or dishwasher.

Plastic siphons have a simple collapsible design and are equipped with clear instructions, so installing the product and connecting the hose from the PMM will not be difficult

Due to the fact that the water first flows into the siphon, sewer odors from biological waste drains will not spread throughout the entire apartment.

For this reason, it is not recommended to discharge the drain directly, without a water seal or at least a loop, into a sewer pipe.

Subtleties of installing a dishwasher in a cabinet

If the cabinet was ordered to fit the dimensions of a specific model, then there should be no problems with installation.

The dishwasher body fits freely into the niche, leaving small gaps on both sides. To reduce vibration, seals are glued to the walls.

When installing some dishwashers, for example, Bosch, there is a mandatory part - a metal protective plate fixed to the bottom surface of the countertop. Cars of other brands may not have it.

To take into account all the connection nuances, the machine must be installed in this order:

• do a fitting first – push the unit into a cabinet or niche, check the dimensions and connectivity;
• put forward and carry out preparatory activities – fix the mounting panels, fasteners and vapor barrier;
• connect the hoses, push the housing into place;
• install decorative panels.

The difficulty is that models from different manufacturers differ, and therefore some installation points also have discrepancies. To avoid mistakes, you must carefully study the instructions and follow all the recommendations step by step.

A few tips that may come in handy during the dishwasher installation process:

Before “planting” the decorative facade on the car door, first degrease its surface, then glue double tape and the panel onto it. This is necessary to be able to adjust the position of the overlay.

When it becomes clear that the holes on the door and the panel match, you can take a screwdriver and tighten the screws. We recommend that you read the detailed instructions for façade installation to the dishwasher.

Lastly, the side fastening is done. Insert self-tapping screws from the inside of the case into the holes opposite the bushings and also tighten them with a screwdriver. It is prohibited to use nails, otherwise machine parts may be deformed during dismantling.

Connecting hoses and testing

We connect the hoses to the machine at the very end, but before the side fastening is made.

The housing moves forward to provide access to all components. Both hoses are usually attached to the body on one side, at the top or bottom.

They protrude a few centimeters, and to provide space in the closet, the back wall is usually simply removed.

The connection is made as described above: the hoses are inserted into the holes and secured with union nuts or clamps. No special tool is needed for fixing; everything is done manually, with a screwdriver or pliers

Once connected, the machine is placed in place for testing. We turn on the machine on the panel, then plug it into the socket, ensure the water supply and press the “Test" or "Start" How to perform testing correctly is explained in the instructions.

If there are no leaks, the machine does not hit the countertop or walls, and the test wash cycle went through without incident, then you succeeded in installing the dishwasher yourself.

But before you start using it, it is advisable to familiarize yourself with rules of operation and maintenance cars.
