DIY dishwasher repair

Many housewives have long acquired special devices for washing dishes, they greatly simplify life and save time. But they break down as often as all other household appliances. Repair dishwasher Bosch SRS (Bosch), Ariston (Ariston), Electrolux ESF (Electrolux) and others can be done at home with your own hands, without contacting a service center.

Design and Diagnostics

A dishwasher is a device designed to wash and rinse a variety of dishes (from table plates to pots, pans, etc.). The external simplicity of the design is very misleading, because this device has a number of modules, regulators and other control mechanisms.

It can be built-in and free-standing. The built-in technique is considered more convenient to use, because it does not require additional space. But at the same time, its repair is somewhat complicated by the lack of quick access to structurally important parts. The scheme has the following form:

In the drawing you see a standard device device. On the control panel (1), various operating modes are selected and configured, here you determine the temperature, flow rate and water pressure. Time is controlled by a timer (14). When the settings are made, you need to load the dishes into the washing chamber. After the door latch (15) slams shut, the contacts close and as in

a washing machine, water will start to flow. Depending on the design, the machine can connect to a boiler or boiler, then warm water comes from the hose hot water (7), at the outlet of which there is an inlet valve (9), or heat the liquid yourself using a heating element (12).

When the water is ready, it begins to be sprayed onto the dishes from above and below using sprayers (2,3). Their operation is controlled by a valve (4), he is also responsible for ensuring that there is not a lot of water in the chamber. When the dishes are washed, the soapy liquid is removed by the drainage hose (5), the camera rinses. The latch opens and dishes can be unloaded. In addition, the diagram indicates:

• 6 is a power cable that connects to the power supply network;
• 8 - filter, with the help of which control and the necessary purification of running water are carried out;
• 10 - motor;
• 11 - pump;
• 13 - a lining.

This device is very similar to all modern dishwashers: Ardo (Ardo), Elenberg (Elenberg), Beko (Veko), NEFF, Hansa (Hansa), Candy (Kandy) and others. The system can be complicated by the presence of various control functions, for example, additional cleaning or blowing dishes. Before starting repairs, be sure to review the user manual and operating tips from the manufacturer - it may be non-separable.

Typical malfunctions of cars:

1. No water is supplied. This can be either a pump problem or a blockage on the filter;
2. The device turns on but does not work. Sometimes it happens that the Samsung machine (Samsung), Hotpoint, Silanos SER or Indesit (Indesit) as it turns on, but can not start. It could close the engine or pump;
3. It does not turn on at all. The motor windings burned out, the power cord is damaged, there is no voltage in the outlet;
4. Water does not drain. The sewer, drain pipe, or drain pump are probably blocked;
5. Water flows from the door during operation. This, of course, broke the door lock, which should jam and ensure the tightness of the container;
6. There is no reverse. Reverse is a very important function of a domed and ordinary dishwasher, in the absence of which you need to repair a timer or replace the motor windings;
7. Water is not heated. A very common malfunction, which indicates a failure of the heater or a malfunction of the time sensor, timer. If the machine is connected to the boiler, then it makes sense to check it for performance;
8. The dishes do not dry. The fan and engine are responsible for this function.

DIY repair

Most of the above problems can be fixed on their own. The easiest way to clean the filters. Depending on the design, you may not even need to disassemble the device. To clean it, you need to remove all the gratings from the chamber, at the bottom there is a filter under them. It can be mounted on a threaded connection or simply inserted into a drain hole. It must be removed and rinsed under running water. In order to eliminate odor, it is also recommended to rinse with detergents.

Step-by-step instructionwhat to do if the pump of the Zanussi ZDTS (Zanussi), Siemens (Siemens) or Krona BDE (Krona) machine is blocked:

1. It is necessary to turn off the water supply and unplug the power cord;
2. Unscrew the filter cylinder and pull the cleaner out. The pump blades must be carefully unscrewed and cleaned. In particular, pay attention to openings that are often contaminated with residues of fat or food;
3. Under the filter is the pump cover. It must be pressed down until it clicks and removed from the container;
4. The pump must be cleaned with a sponge or soft brush;
5. Carefully look at its walls, sometimes broken dishes get in here, which can violate the tightness of the part. If cracks or holes are found, the pump will have to be changed.

If the fault is in the engine or other internal part, you will have to disassemble the dishwasher for repair. This process is pretty fast. You just need to unscrew all the screws that hold the case. Note that instead of removing all the mounts, try to pay attention only to those that are located near the place of failure - this will speed up the process.

Instructions on how to disassemble a Whirlpool (Virpul), Siemens, Miele, Kaiser (Kaiser), AEG (AEG) dishwasher for engine repair:

1. You need to remove the lower front panel. Under it is the connection of the motor and pump, they are also removed;
2. Water may remain in the pump and pipes, so prepare a container in advance to drain it;
3. First, the pump cover is removed as described above. After the pump itself is turned out of the base and removed. Underneath is an engine. Gaskets are often installed between parts, so proceed carefully so as not to damage the seals;
4. Check the performance of the parts. Reinstallation is the same.

If you are not confident in your abilities, then it is better to immediately contact specialists. A quality foreman will not undertake to carry out urgent warranty repairs after preliminary intervention in the design of the dishwasher.
