The process of installing a 45 cm built-in dishwasher into the kitchen begins with an accurate check of the dimensions of the prepared niche and the state of the supplied communications before the start of installation work. The narrow format of the equipment with a width of 45 centimeters requires special attention to the side walls of the cabinet, since tolerances are minimal here, and any deviation from the perpendicular can lead to jamming of the case. Before moving the unit, you must make sure that the water liner and the drain hose have a sufficient length for free maneuver, but do not form loops that prevent a tight landing.
Installation of narrow format equipment is often complicated by the fact that in standard kitchen sets the space is limited not only by the width, but also by the depth of the basement. If you plan to install yourself, it is critical to remove the dimensions of the inner part of the pencil case in advance, including the thickness of the shelves and the presence of horizontal screeds. Incorrectly calculated space will lead to the fact that the car simply does not stand in place, or its door will rest against the elements of furniture when opened.
The first stage of the work is the dismantling of all removable elements of the kitchen set, which can interfere with access to the niche. You will need to remove the doors of adjacent cabinets, drawers and possibly dismantle the countertop if the kitchen design does not allow you to install the machine from below. Complete liberation of the working space Ensures that you do not damage the furniture or the machinery itself in the process of moving heavy equipment.
Next, you should check the horizontality of the floor at the installation site, since the built-in 45 cm equipment is extremely sensitive to distortions. Use the building level to assess the surface; if the floor has a significant slope, adjustment of the machine support legs or lining of the aligning materials will be required. Perfect horizontal necessary for the correct operation of the water drain system and prevent leakage through seals.
⚠️ Attention: It is strictly forbidden to install the dishwasher on the side wall or put it upside down without a special protective gasket, as this can damage the internal nodes and thermal insulation.
Preparation of communications includes the organization of a connection point to the water supply and sewerage directly in the adjacent cabinet or under the sink. For narrow 45 cm models, a combined siphon with a diversion for the dishwasher is often used, which saves space in the basement area. Make sure that the shut-off valve is installed in an easily accessible place for prompt water closure in case of an emergency.
Requirements for the dimensions of the niche and furniture preparation
The standard width of a 45 cm built-in dishwasher is exactly 450 millimeters, however, the actual tolerances can vary depending on the furniture manufacturer. The interior volume should be free of unnecessary partitions, and the back wall of the cabinet often requires complete or partial removal for the passage of hoses. Niche depth It should take into account not only the body of the machine, but also the space for placing communications from the rear.
- 📏 The width of the opening should be strictly 450 mm with a tolerance of not more than + 2 mm, so that the side walls of the machine fit tightly to the furniture.
- 📏 The height of the niche is usually 815-820 mm, which allows you to adjust the supporting legs of the machine to align with the neighboring tubes.
- 📏 The depth of the cabinet should be at least 550-600 mm so that the body does not protrude beyond the facades and there is a gap for hoses.
When preparing furniture, pay special attention to the strength of the side walls of neighboring cabinets, since it is to them that the dishwasher facade will be attached. Thin walls of chipboard may not support the weight of a heavy door with ceramic utensils, so sometimes you need to install additional reinforcing slats. Strength of construction - a key factor in the durability of the operation of built-in equipment.
If the kitchen set has a basement, you need to make sure that it does not interfere with the opening of the car door in the lower position. Often it is required to make a cut in the basement bar or install it with a indentation so that the dishwasher legs and the lower edge of the door have a free run. The absence of contact between the moving parts of the machine and the elements of the kitchen is a prerequisite for safe operation.
Before the final installation, be sure to remove the transport wedges and foam inserts that fix the peg and pump inside the case.
Connection scheme to water supply and sewerage
Connection to the water supply system is carried out through a special shut-off valve, which is recommended to be installed on a tee coming from the mixer or a separate insert into the pipe. For embedded models 45 cm is often used flexible liner length up to 1.5 meters, but it is better to choose options with a metal braid, which have a high margin of safety. The pressure in the system must meet the requirements specified in the technical passport of the device, usually this range from 0.04 to 1.0 MPa.
The organization of the draining of dirty water requires the installation of a siphon with a return valve or the use of an Aquastop valve built into the machine to prevent sewage from getting back into the machinery. The drain hose must be fixed at a height of 40-60 cm from the floor, creating a water shutter that blocks unpleasant odors. Leakability of compounds is checked by visual inspection and probing of docking sites after the first test run.
| Parameter | Value/Requirement | Note |
|---|---|---|
| Diameter of the drain hose | 19-22 mm | Standard for most models |
| Length of feed hose | 1.5 - 2.0 m | No tension and no overbending. |
| Water temperature | Cold (up to 25°C) | Hot connection only if specified |
| Maximum pressure | 10 bar (1 MPa) | Requires a high pressure reducer |
It is important to correctly place the hoses inside the cabinet so that they do not twist and are not transmitted by the body of the machine when it is installed in place. It is recommended to use plastic clamps or clips to fix hoses to the side walls of the cabinet or back wall. Free current of water ensures the quiet operation of the pump and the effective removal of contaminants.
☑️ Checking before water start
Electrical connection and wiring requirements
A dishwasher is an energy-intensive device that consumes significant current in the water heating mode, so a separate socket with grounding is required to connect it. The use of extension cords or tees is not recommended, as this creates a risk of overheating of contacts and fire. Copper wire cross-section for connection should be at least 1.5 mm2, and preferably 2.5 mm2 for power reserve.
⚠️ Attention: The dishwasher plug should be located in the adjacent closet or on the side wall, but never directly behind the machine body to avoid overheating and provide access for emergency shutdown.
If your house is old wiring without grounding, you need to take care of the installation of a protective shutdown device (RCD) or a differential machine. This device will instantly shut down power when current leaks, which is critical for safety given the proximity of water and electricity. Landing of the hull prevents electric shock during breakdown of the insulation of the heating element.
When laying a cable, avoid places where it may come into contact with hot surfaces or sharp furniture edges. The cable should lie free, without tension, so that when the machine vibrates during operation, there is no damage to the insulation. Check the reliability of the contact plug in the socket: it should not warm or spark during operation.
Facade fastening and door adjustment
Installation of a decorative facade is the most important step that determines the appearance of your kitchen. The facade is attached to the dishwasher door using a special fastening set that comes with a set, or through a system of guides depending on the type of fastening (slider or rigid). Precise positioning The facade relative to the adjacent doors, the headset requires patience and level use.
- 🔨 For rigid fastening, use screws, screwing them through holes in the car door into the prepared holes of the facade.
- 🔨 With the slider method, the facade is suspended on hooks, which allows you to compensate for small size errors.
- 🔨 Be sure to use the drilling templates (masks) going into the instructions so as not to damage the facade with the wrong holes.
After hanging the facade, it is necessary to adjust the tension of the springs of the door mechanism so that the door does not slam spontaneously and does not open too easily. Adjustment is carried out by special screws located in the lower front of the machine, access to which is opened after removing the base bar. Balancing the door Ensures comfortable use and prevents water from leaking when opened during the wash cycle.
Secrets of facade adjustment
If the facade is skewed, use adjusting screws at the corners of the car door to align its position relative to the countertop.
Final installation and test launch
After all connections and adjustments are completed, gently push the dishwasher into the niche, ensuring that the hoses and cable do not get hushed up. Lock the body in the furniture frame with fasteners through the upper part or side walls so that the machine does not move forward under the weight of the loaded dishes. Hard fixation The body also reduces noise and vibration when operating.
The first start is made without dishes, but with the addition of special salt for dishwashers and rinse in the appropriate compartments. Select the maximum temperature program or the Quick Wash mode to check the tightness of all joints and remove the residues of the factory lubricant. Carefully monitor the place of connection of drain and water supply in the first minutes of work.
If you find a leak during the test cycle, immediately stop the program, shut off the water and eliminate the cause of the malfunction. Check the clamping density, the integrity of the gaskets and the correct installation of filters. Successful completion of the test This means that your dishwasher is ready for daily use.
⚠️ Attention: Never leave the first run unattended, as in the event of a factory defect or installation error, this can lead to a kitchen flood.
The main secret of success is not to rush the car into a niche until all connections are fully checked with water under pressure.
Frequently Asked Questions (FAQ)
Can I connect a 45 cm dishwasher to hot water?
Technically, this is possible if the model supports such a mode (as indicated in the instructions), but experts recommend connecting only to cold water. This is because the quality of hot water from the central water pipe is often low, it contains more impurities and chlorine, which more quickly disables the heat exchanger and filters of the machine.
What if the car does not get into a niche because of the protruding siphon?
In such cases, it is necessary either to replace the standard siphon with a flat (bottom) option, or to make a neat cutout in the back wall of the cabinet or shelf under the sink. Sometimes it helps to shift the machine a little to the side, if the design of the kitchen module allows.
Do I need to level the car if the floor is perfectly flat?
Yes, adjustment of the supporting legs is mandatory even on a flat floor. This is necessary in order that the upper cover of the machine fits tightly to the underside countertop, which provides additional noise insulation and fixation of the body in the furniture.
How often should I change the filter in the dishwasher?
The rough filter should be washed with running water after each wash cycle or as it is contaminated to ensure a quality water drain. Deep cleaning with detergents is recommended every 1-2 months depending on the intensity of use.
