Independent installation and connection of the dishwasher to communications

Proper operation of the dishwasher depends not only on the quality of spare parts and assembly. Proper connection of the dishwasher also affects the performance of the main functions - thorough washing, rinsing, drying dishes.

In order not to encounter an accident, leakage or a quick repair, you need to prepare for the installation of the machine, and then carefully and carefully perform all the steps of the connection - independently or with the help of specialists.

Site selection based on installation method

The sooner you think about purchasing equipment, the less trouble there will be with the further improvement of the kitchen.

Ideal option - the complex repair including:

  • drafting the project;
  • laying of water and sewage pipes;
  • carrying out separate power lines for powerful units;
  • finishing of the room;
  • installation of furniture and equipment.

In this case, the risk that there will not be enough niche for the dishwasher or its size will not fit, is reduced to zero. Walls with removed connectors look neat, safety requirements are met.

The layout of the outlets in the kitchen

Modern kitchen is a room filled with a large number of large and small appliances. Drawing up a project helps to locate both the devices themselves and the connection points - sockets.

The installation location depends on the type of machine, respectively, on the method of installation. All devices can be divided into two categories:

  • freestanding, portable, representing a mobile unit;
  • recessed, stationary, for the installation of which a cabinet is required.

The size of the dishwasher is also important for proper installation. Allocate a subcategory of compact machines, with reduced dimensions.

Among them are both freestanding appliances, designed for installation on a tabletop or in a niche cabinet, and embedded.

Dishwasher layout options:

Built-in type dishwasher installed next to the sink

The proximity of communications facilitates the process of water supply and removal of economic waste. Cleaning dishes before loading into trays near the sink is also much more convenient.

The machine is integrated into the “island” in the center of the room.

If the work area is partially transferred to the "island", which is an autonomous unit of modules in the center of the kitchen, then the dishwasher can be embedded in it

The dishwasher is set in a free-standing kitchen cabinet

The complexity of the installation lies in the location of furniture that is far from communications. The machine will require an extension of pipes or hoses of more than 1.5 m.

Free location of a free-standing model

A model not intended for embedding can be put on any free space, but with one condition - water supply, sewage and electricity as close as possible.

Compact PMM are called desktop. Most often they are installed directly on the tabletop, near the sink or work surface - cutting table

Among the small-sized models there are also built-in dishwashers that can be placed either under the table top or higher, in a “canister” or a cabinet at a height of 90-120 cm

In order not to occupy a useful surface on the working kitchen table, the dishwasher can be placed in one of the free niches in the cupboard, like a microwave

If the dimensions of the compact machine allow, it can be placed in a cabinet that hides the washing communications. This method makes it easier to connect the device, but it is not very convenient to use.

You need to think in advance how and where to install the dishwasher. The main thing is to correctly position the unit with respect to communications - to bring it as close as possible to the pipes.

We also recommend in the accessibility zone to install cabinets for dishes and other utensils, which is intended for washing in the dishwasher.

The cleaning process will be much faster if the plates are cleaned from large pieces, the dishes are placed in the dishwasher's trays, and clean dishes are laid out on the shelves from the same place.

The importance of using instructions

Manufacturers are responsible for the quality of their products, so new dishwashers have a warranty - from 12 months to 5 years. To hand over to service a defective Chinese unit more often is possible within 1 year, European - 2 years.

However, improper installation of the machine, contrary to the requirements of the manufacturer, deprives the buyer of the right to free repair or replacement of equipment.

Consequently, the instruction and the main document and the installation manual for the dishwasher. This is a booklet with a detailed description of the installation process and the connection of a new dishwasher to the water supply and sewage system.

Also, the instruction contains technical requirements that relate to the parameters of the connected electrical network, pressure in pipes, etc. Machine specifications also need to be considered.

Dishwasher installation diagrams

In the instructions, the description of all actions is accompanied by clear diagrams, which show how to properly attach the hoses, fix the machine in the cabinet, and position it relative to the pipes

So, full-built PMM with a large mass is placed on the floor, additionally fixing on the walls of the cabinet or countertop.

But compact models can be integrated into the cabinet, which is able to withstand their weight, even taking into account the loaded containers and water.

If within six months some parts of the dishwasher fail due to improper location of the hoses or strong vibration of the body, they will have to be changed at their own expense - the warranty is removed.

Connecting PMM to communications

In order for the machine to work, it is necessary to ensure the supply of electricity and cold water, as well as to equip the discharge of the used liquid into the sewage system.

If a separate socket for the PMM is installed during the repair, the first stage can be skipped, but the next two ones are performed during the connection process in any case.

Stage # 1 - Installation of a separate outlet

We do not recommend using an extension cord that is inserted into a common outlet, filter or tee.

Such "intermediaries" can not withstand the load, fail or even melt. Be sure to require a separate wiring product "Euro" standard, with grounding and moisture protection.

Socket block on the wall

Blocks built into the wall or overhead sockets are installed in convenient places for use: above or below the worktop, but with easy access

It is not recommended to fasten the socket block too close to the floor - during a leak, water can get inside the product. The minimum distance from the floor covering is 15-20 cm.

This is true for embedded models, when the outlet is placed on the wall behind the dishwasher case. For detached units, the usual location - at a distance of 40-90 cm from the floor.

In addition to the outlet, you will need a wire, preferably in non-combustible insulation and with a cross section designed for increased load. A suitable option is a 3-core copper wire VVGNG 3 * 2.5.

Wire to connect the outlet

The stripped ends of the wires are inserted into the terminals, twisted with screws or secured with snaps. For the ground wire, which can be recognized by the yellow-green insulating film, is a separate terminal

Installing an outlet in a sub-outlet is an elementary household skill, so many cope with its installation on their own. but if there is not enough skills, it is better to entrust all works on electrical equipment to a specialist.

From the outlet, the wire is pulled to the electrical panel, where a separate circuit breaker is installed.

Similar machines are recommended to be installed on each powerful household appliance - if necessary, you will not have to turn off the entire “kitchen” line.

A sample of a suitable circuit breaker for the line to the dishwasher. Rated current - 16A, BP / Har-ka current - C, current limiting class - 3

Even if you theoretically know how to install a switch on a din-rail, a representative of the Management Company or another service organization must perform all electrical work in the panel.

After installation, you must check how the outlet works. To do this, turn on the machine and insert the plug of the simplest device, for example, a desk lamp, into the socket.

Stage # 2 - Water Supply

To use the machine at any convenient time, you should attach the water supply hose to the pipe or flexible connection to the threaded connection using a tee or adapter.

Hose connected using tee

The easiest way to make a tie in the network, if the dishwasher is located next to the sink with a mixer. Flexible eyeliner okruchivayut, instead set the tee

The length of the water supply hose is 1-1.5 m. It is at such a distance from the highway that manufacturers recommend installing a dishwasher so that it functions correctly.

Procedure:

  • unscrew the flexible hose of the mixer from the pipe;
  • we attach a ½ inch tee “mom” and “dad” in a straight line, with a ¾-inch tap on the side and a water tap;
  • For tightness of the connection, we use a fum-tape or another seal;
  • ¾ inch pipe in a convenient direction for connecting the hose;
  • fasten the flexible ½-inch branch pipe and the dishwasher hose to the side branch;
  • we test water supply, if necessary we tighten connections.

Depending on how far the machine is from the car wash, this or that connection method is selected.

Multiple connections collector used

If instead of a single dishwasher you need to connect several devices that require cold main water supply, use a collector and a set of adapters

The correct insert in a plastic pipe

It happens that the car is installed far from the sink, but near the pipe with cold water. Then a tee with a shut-off tap is cut into the main, and water flows directly into the dishwasher

The tee is installed on a steel pipe

In order not to cut a length of pipe, use a repair clip. It is bolted to the tie-in area, then a hole is drilled from the side, the valve is mounted and the hose is screwed

The use of flexible hoses is not always advisable, therefore, if the machine is installed far from the main line, water supply is increased by pipes

All methods are functional and are good in their own way, so it’s up to the owners of the unit to decide how to connect a new dishwasher with their own hands, based on specific conditions.

Connection parts are sold in plumbing stores, so there should be no problems with the purchase of tees, collectors, and seals. Try not to save on details and choose even more expensive, but high-quality components and gaskets.

Features connect compact devices. In the instruction of mini-dishwashers the installation method is noted without being permanently connected to communications.

Before washing, the water supply hose is put on the mixer spout, and the drain hose is lowered into the sink.

Compact Dishwasher at the Sink

The lack of a permanent connection is relevant only in one case - if the dishwasher often has to be moved to another place or transported to another house, for example, to a cottage

Some use this method, but it harbors uncomfortable moments:

  • you have to do extra things every time;
  • hoses lie in a conspicuous place and spoil the overall look;
  • due to the frequent connection / disconnection of the connections, they quickly become loose and wear out;
  • a strong pressure of water can "knock out" the hose from the sink, eventually a flood will occur;
  • the sink remains busy while the washing and rinsing process is going on.

Therefore, for reliability, it is better to choose a specific place for installation and ensure a permanent hermetic connection.

About connecting to hot water. The ability to connect to both pipelines - with hot and cold water - is considered by buyers as a useful option and even ready to overpay for a “useful” addition.

However, there are many reasons why you should not “save” on heating the machine and use hot water:

  • hot water is worse than cold in composition;
  • the electronic unit will “fly out” if the water temperature in the network is higher than the programmed one;
  • with centralized hot water often turn off.

The savings themselves are also in doubt. Modern models and so are considered quite economical, given the small power consumption.

And with the use of hot water, some nodes may fail prematurely, and a significant amount will have to be spent on repairs.

Hot and Cold Water Hose Connection Diagram

Whether your dishwasher assumes double connection, it is possible to find out, having studied the instruction and schemes of connection. On the back of the machine there are two water supply hoses instead of one

A gross error is the connection of the hot line to a device designed exclusively for the supply of cold water. Parts of the machine will not withstand the heat and quickly break.

Stage # 3 - drainage device

Drainage - a prerequisite for the proper operation of the dishwasher, for this is provided a drain hose. There are two ways to connect it to the sewer line:

  • directly into the pipe by means of a rubber coupling;
  • through the siphon located under the sink.

The second option is the most successful, since it immediately solves all problems: eliminates odors, protects against the reverse flow of fluid, creates the necessary pressure in the pipe, protects from leakages.

You will have to purchase a new siphon if the old one is not designed to connect household appliances, and consider the location of the drain hose.

Siphon with an additional branch pipe

Hose connections for connecting dishwasher or washer hoses are attached to the side (or two sides) of the siphon, have a conical shape for convenient winding and tightening the clamps

Plastic insert for lifting

To prevent the backflow of fluid, the hose must be raised 40-50 cm above the floor. When connected via a tee, this can be done using a plastic stop

Hose loop

If there is no special plastic device at hand, and the hose is rigid enough, you can temporarily make an arbitrary loop, lifting it up. But this is not a reliable option.

Increased the length of the drain hose

If the machine is located far from the sewer pipe or siphon, it will be necessary to extend the hose. To do this, take another hose of the same diameter and attach it to the socket, securing the clamps

In order to simultaneously observe the tightness of the connections and normal, without vacuum, the pressure in the line, with a direct connection (without a hydraulic seal), an "anti-siphon" valve is used.

This is an inexpensive plastic product that is inserted directly into the slot in the hose.

This connection communications can be considered complete. After the test run, it will become clear how correctly the hose connections are made and whether additional sealing is needed.

The nuances of the installation of embedded technology

Freestanding units simply install on the place provided for them, then make the connection.

Embedded models need to be integrated into the furniture set. Here are some helpful tips that may come in handy during the installation process:

  • the dimensions of the embedment cabinet must correspond to the dimensions of the dishwasher's case; for comparison, you need to check with the schemes provided by the manufacturer;
  • Be sure to use the protective devices that are included - a metal bar to strengthen the tabletop, a vapor-protective film;
  • Twist the legs to level the body, usually there are three - two are in front and one in the back;
  • do not forget to insert the side sleeves and fix the housing with screws;
  • fix decorative panels strictly according to the templates or stencils that are also included in the package.

Dishwashers from different manufacturers may have structural differences, therefore should be based only on the specific model instructions.

The document clearly states how to install the dishwasher correctly, in what order it is necessary to take steps for installation and connection of communications.
