Good day!
I want to say thanks to the previous authors and share my experience of my first renovation.

1.The E3 error (temperature sensor malfunction) jumped out, the machine started up, took water and drained it - the heating element and the temperature sensor rang, and also checked the operation of the condenser.
2. Confused the isolation of the presosstat contact darkened, removed the contact, cleaned it.
3. Didn't find anything Sobral, started to run the dishwasher in different modes and, lo and behold, it started working, but not completely.
Another error E1 (insufficient pressure) popped up; the engine is noisy - water is not collected, suspicion fell on the presosstat.
4. I barely removed the clamp, I had to grind off the zagigulin with a file. When blowing in, there were no clicks, I disassembled the micrik (elementary). It works when disassembled, you put the lid on it hangs.
The reason is that there was an overgrowth on the lid, so the contact got stuck.
The fix - I scratched it with a screwdriver, the nodules worked and that's it. There were obvious clicks.
The price of the issue is zero rubles.

Accidentally came across a spare part with a pressosstat, according to the picture it looks like it is an article number 674000300068 Manufacturer Kaiser.

There is a dishwasher in almost every home - this small unit greatly facilitates the work in the kitchen, saving our time and effort on washing and drying dishes. But, like any household appliance, even the highest quality dishwasher begins to malfunction over time. Fortunately, most of the malfunctions that may arise during its operation can be eliminated independently without calling the wizard. In most cases, they are associated with wear of the main units and parts, as well as the consequences of improper operation. In any case, it is very worthwhile to understand the device and the principle of operation of a home dishwasher. This will save you from unnecessary costs for the services of a service center and washing dishes by hand due to a long downtime of a failed unit.

The design of household dishwashers is in many ways similar to the layout of washing machines. The main difference lies in the absence of a rotating drum in the dishwasher and in the presence of a number of specific functions that ensure the process of washing dishes.

The interior of the dishwasher can be viewed by opening its front wall. The list of the main units and components of the unit includes:

1. Control Panel.
2. A board with a processor.
3. Electric motor.
4. Dispenser.
5. Dryer air path.
6. Turbofan.
7. Upper and lower baskets.
8. Cutlery basket.
9. Upper and lower rocker arms.
10. Discharge pump.
11. Filter system and softener.
12. Pallet and drainage.
13. Heating element.
14. Counterweight.
15. Capacitor.
16. Water supply valve.
17. Top and bottom (side) nozzles.
18. Detergent container.
19. Float regulator.
20. Ion exchanger.
21. Salt container.

Dishwasher interior

The basis of the dishwasher is a sealed metal case, covered from the inside with a stainless composition, insensitive to temperature fluctuations and the aggressive effects of detergents and equipped with sound and thermal insulation. The control panel is located on the front of the machine. It consists of a timer (microcontroller), control buttons and an indicator display.

Dishwasher control panel

Spray blocks (impeller) consist of a system of pipes and nozzles.Through them, heated water with detergent is supplied to the interior of the machine under pressure, which ensures high quality cleaning and washing of dishes.

Dishwasher impeller sprayer

The dishwasher float switch is the primary protection against leaks. The drain unit has a design similar to the drain in washing machines.

And one of the main components of the dishwasher is the water pump, which is installed in conjunction with the electric motor. The filtration system is no less important - it serves to catch food debris and other debris.

The dishwasher is hidden from view. You simply put the dirty dishes and cutlery in the baskets, add the detergent, close the front wall and turn on the start button. But knowing what is happening inside the unit when it washes the dishes does not hurt at all - this will allow you to determine the cause of the failures much faster and correctly eliminate them.

The dishwasher works according to the following algorithm:

1. Starting water drain.
2. Water filling.
3. Start washing.
4. Adding detergents.
5. Heating water.
6. Washing dishes.
7. Draining.
8. Filling in rinsing water.
9. Rinsing. Rinsing dishes
10. Final drainage of water.
11. Drying dishes.

Condensing dishwasher

Washing programs - sequences of instructions executed by the microprocessor - differ in such parameters as:

• the presence or absence of the pre-soaking function;
• the degree of water heating (50-75 o C, sometimes higher);
• program execution time.

Dishwasher programmer with microprocessor

The operation of the dishwasher with the implementation of the functions of the selected washing program is carried out in the following order:

1. The microprocessor checks that the door is closed and issues a flush command to the drain pump.
2. After stopping the pump, fresh water is collected, the level of which is monitored by a special sensor.
3. A circulation pump is turned on, which creates pressure inside the housing, water enters the impeller, which begins to rotate under pressure. In the meantime, the dispenser opens and the detergent enters the interior of the machine. Dishwasher circulation pump
4. The heating element is heating the water.
5. The water is drained off using a drain pump. Dishwasher drain pump
6. A new portion of rinse water is added.
7. After rinsing, the used water is emptied out and the drying function is activated.
8. Upon completion of the drying of the dishes, a sensor is triggered, the signal of which forces the microprocessor to open the lock of the front wall.

Using kitchen equipment every day, you will inevitably learn to distinguish between how it works - properly or with some kind of malfunction. And not all of the latter are associated with obvious malfunctions in the technology itself.

If your dishwasher does its job poorly, it is quite possible that you are simply breaking the operating mode.

1. White streaks and streaks on dishes

Streaks appear when the user has loaded too much rinse aid or salt. Dirty drips indicate the opposite - in this case, it is worth increasing the dosage of the detergent.

Too much detergent

1. Poor drainage of used water

Food residues on the bottom of the dishwasher and on the dishes themselves are a sign of clogged filters. Manufacturers recommend cleaning them almost after every wash, after draining the remaining water from the system.

1. Poor cleaning of dishes from food debris.

Any, even the best dishwasher is unlikely to cope with thoroughly burnt or not washed dishes - in this case, you should do a little work with your hands before loading into the machine.

Before loading: manual cleaning of a burnt pot

1. Excess foam

If there is too much foam, then the rinse aid is far overloaded. Just adjust the machine's dispenser or add a little more powder, an excellent defoamer.

The reasons for the unsatisfactory cleanliness of the dishes after washing can also be:

• improper placement of dishes in the interior of the dishwasher - water does not get on all surfaces; Positioning the dishes correctly in the dishwasher
• the impeller does not spin - the sprayer is blocked by excessive loading or improper installation of the dishes;
• no detergent is being supplied - it is simply over, or its supply is blocked by dishes or food residues;
• no water is supplied from the impeller - you need to check the nozzles of the sprayer and, if necessary, clean them with a stream of water, after removing them from the machine;
• wrong choice of washing mode.

If you are sure that you have strictly adhered to the operating mode and even after checking and performing all the necessary service procedures, the machine still works very badly or refuses to wash the dishes altogether, this most likely means that there are technical malfunctions.

Diagnostics and elimination of malfunctions due to which the operation of the machine is impossible:

1. The machine does not turn on or has an electric shock

• in more than a third of cases, this means a break in the electrical circuit - the current simply does not reach the engine and, most likely, due to a blown fuse. It is also worth checking the integrity of the plug and power cord; Wiring diagram for a simple dishwasher
• a frequent reason for the absence of signs of the life of a dishwasher is a loosely closed door;
• lack of water in the working chamber: you need to check the serviceability of the tap, the permeability of the inlet filter and the integrity of the supply hose; Dishwasher filter
• if there is voltage on the outer metal parts of the machine, check the health of the heating element and the presence of water softening salt in the dispenser. Heating element of a dishwasher of a flow-through type

1. Defective programmer

If the dishwasher board burns out, it will be possible to repair it only in the workshop - this will require special knowledge, tools and practical skills.

In most cases, the programmer must be replaced, but this can seriously hit your pocket. Therefore, it is worth asking about the successful experience of repairing household dishwasher boards from familiar craftsmen.

If you nevertheless managed to start the unit, however, it is obvious that it is not working correctly or does not perform its functions, you should pay close attention to the following points:

1. Knocks and other extraneous sounds during the operation of equipment

Check the integrity of the gun bearings. The bearings of the main or drain pump unit may also knock. The first works periodically, pumping water into the system, the second - at the end of each cycle.

1. Water does not flow into the cooking chamber

If the filter and water supply hose have nothing to do with it, most likely the culprit is a broken inlet valve that needs to be replaced.

1. Pressure switch does not work

It is necessary to remove the terminals from this part and clean the branch pipe to which the plastic pressure tube fits - a working switch, when triggered, emits a soft click.

1. Machine stops in the middle of a cycle

The reason for this is most often a faulty pump. But first, you should check the recirculation filters, the water intake path, the water heater or the thermostat.

Dishwasher circulation pump

1. The dishes are washed with cold water

Most likely, your car does not have a thermal sensor, so its programmer did not notice that the heating element or the heating automatics were out of order. In this case, you will have to replace the broken electronics, which is recommended to be done at the service center.

Dishwasher removal and disassembly must be carried out in accordance with the manufacturer's instructions.

Removing the front panel of the built-in dishwasher

Well-known brands provide more detailed data on the manufactured equipment, incl. in Russian.In other cases, you will have to look for a sensible algorithm of actions on the Internet, or trust your technical instinct - after all, the dishwasher device is not super-complicated and anyone can figure it out using ingenuity and the tool necessary for work.

Strict adherence to the operating mode reduces the likelihood of damage to the dishwasher at least fourfold. Therefore, immediately after installation, thoroughly study the operating programs of the unit and explain to your household in an accessible way how to use it correctly.

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

A dishwasher is a device designed for washing and rinsing various dishes (from dinner plates to pots, pans, etc.). The external simplicity of the design is very deceiving, since this device has a number of modules, regulators and other control mechanisms.

It can be built-in and free-standing. The built-in view technique is considered more convenient to use, since 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 diagram looks like this:

Photo - dishwasher design

In the drawing you can see the standard design of the device. On the control panel (1), you can select and configure various operating modes, here you define 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, like in a washing machine, water begins to flow. Depending on the design, the machine can be connected to a boiler or boiler, then warm water comes from a hot water hose (7), at the outlet of which there is an inlet valve (9), or to heat the liquid independently using a heating element (12).

When the water is ready, it starts to spray onto the dishes from the top and bottom using the spray nozzles (2,3). Their operation is controlled by a valve (4), which 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 drain hose (5), the chamber is rinsed. The latch opens and the dishes can be unloaded. In addition, the diagram indicates:

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

This device is very similar in 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 the dishes. Before starting repairs, be sure to check the manufacturer's user manual and operating tips - it may not be removable.

Typical machine malfunctions:

1. No water is supplied. This could be either a pump problem or a blockage in the filter;
2. The device turns on but does not work. Sometimes it happens that a Samsung (Samsung), Hotpoint, Silanos SER or Indesit (Indesit) machine turns on, but cannot start. It could close the motor or pump;
3. Does not turn on at all. The motor windings are burnt out, the power wire is damaged, there is no voltage in the outlet;
4. The water is not drained. Probably, the sewage system, drain pipe or drain pump is faulty;
5. Water flows from the door during operation. This, unambiguously, 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 it is necessary to repair the timer or replace the motor windings;
7. The water is not heated. A very common malfunction, which indicates a breakdown of the heating element or a malfunction of the time sensor, timer. If the machine is connected to a boiler, then it makes sense to check it for performance;
8. Dishes do not dry. The fan and motor are responsible for this function.

Most of the faults mentioned above can be fixed on your own. The easiest way is to clean the filters. Depending on the design, it may not even be necessary to disassemble the device. To clean it, you need to remove all the grates from the chamber; there is a filter at the bottom under them. It can be installed on a threaded connection or simply inserted into a drain hole. Take it out and rinse it under running water. In order to eliminate odor, it is also recommended to wash with detergents.

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

1. You need to turn off the water supply and remove the power cord;
2. Unscrew the filter cylinder and pull the cleaner out. The pump blades must be carefully unscrewed and cleaned. Pay particular attention to openings that are often contaminated with grease or food debris;
3. The pump cover is located under the filter. Press on it until it clicks and remove it from the container;
4. The pump must be cleaned with a sponge or soft brush;
5. Look carefully at its walls; broken dishes sometimes get here, which can break the tightness of the part. If cracks or holes are found, then the pump will have to be changed.

If the problem is in the engine or other internal part, the dishwasher will have to be disassembled for repair. This process is quite fast. You just need to unscrew all the screws that hold the case. Note that instead of removing all fasteners, try to pay attention only to those located near the breakdown site - this will speed up the process.

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

1. You need to remove the lower front panel. Under it is the connection of the engine and pump, you also remove them;
2. Water may remain in the pump and pipes, so prepare a container in advance to drain it;
3. First remove the pump cover as described above. After that, the pump itself is turned out of the base and removed. The engine is located under it. Gaskets are often installed between the parts, therefore, proceed carefully so as not to damage the seals;
4. Check the functionality of the parts. Reinstallation is similar.

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