Do-it-yourself Elenberg dishwasher repair

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.

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.

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 malfunctions 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 for a long time - in this case, you should do a little work with your hands before loading into the machine.

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, the closest attention should be paid 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.

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 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 household members how to use it correctly.

At one time, a British magazine conducted a survey of readers about the quality of household appliances. There was only one unequivocal conclusion - there is no problem-free household appliances. Moreover, the models of the elite - class, after 5 - 6 years, begin to malfunction. Noteworthy is their conclusion about the degree of reliability of dishwashers of leading brands. This is how the British named Ariston, Bosch and Electrolux the leaders in durability among the brands.

But, as mentioned, even the most reliable home assistant starts to malfunction.And when this happens there are two ways out: roll up your sleeves and take on repairs yourself, or call for help from a specialist from the service center. Statistics speaks in favor of the first option, namely, most dishwasher malfunctions are eliminated at home. And in the statistics of service centers the leading place is occupied by “no drain”.

Therefore, minor and not very complex malfunctions can be completely eliminated by yourself, but for this you need to get acquainted with the device of the dishwasher and consider possible options for repairing dishwashers. Which is the purpose of this article.

The body, as in any household appliances, serves as a base on the basis of which all the main components and assemblies of the machine are located. The main elements of a dishwasher include the following:

• Control panel, which is always located on the front side of the machine. It consists of a digital microcontroller (timer), control buttons and an indicator display (which can be used as an indicator beam, which is projected onto the floor surface).

• Spray blocks or impeller. This is a dishwashing water supply system. Consists of a system of pipes and nozzles (there are two of them: upper and lower). Due to the special design, water and detergent are supplied under high pressure, which ensures high quality dishwashing.

• A float switch is a means of protection against water leakage. A hollow plastic cylinder floats up at a certain volume of water and thereby closes the contacts. Depending on the design, these contacts close the pump activation circuit for pumping out water or perform emergency closing of the water supply valve to the machine.
• The drainage unit consists of a drainage pipe, which is connected to a common sewage network and a sump pump. The principle of operation is identical with the drain in washing machines, who knows.
• Water inlet with built-in inlet valve controlled by a digital microcontroller.
• The water pump is used to supply water to the spray guns and, on some models, to drain the water. As a rule, it is located together with an electric motor, which starts the pump.
• Filters are designed to "catch" food debris and other objects.

These are actually all the most important and most common elements of dishwashers in case of malfunctions. Of course, different manufacturers can add other blocks that expand the functionality of the unit. But all of the above is the base, having dealt with it, you can easily deal with the individual structural elements of your car.
