What could be the cause of the malfunction?

If the dishwasher has served you for more than 5-6 years, then it is likely that the malfunction is caused by the natural physical wear of the components. If the dishwashing technique is relatively new, then the breakdown and the resulting errors of dishwashers can provoke the following situations:

• Poor-quality assembly, defective components. Especially often this is found in products from little-known manufacturers and inexpensive models of Chinese production. The technique of the Bosch trademark in this respect practically does not fail.
• Loading of heavily soiled dishes into the chamber. Remains of food contribute to the rapid clogging of the filter. In addition, if the plates are very dirty, the machine does not wash them well and it is necessary to rinse the dishes by hand.
• Defective outlet.
• Errors in connection with the connection of dishwashing equipment, for example, an excessively long drain hose or poor attachment of a hose with cold water.
• Use of a low-quality detergent that does not wash dishes properly.
• Loose door closing. The machine switches on only after the latches are activated. If the door does not hold by itself, it can not be considered a failure. This factory marriage.
• Incorrect loading of dishes, as a result of which it is washed unevenly. Before loading the dishes, you must carefully read the instructions. The upper part is loaded with cups and plates, in the lower part - more dimensional kitchen utensils, for example, pots.

Important! When loading the dishwashing equipment, make sure that the glasses and cups are placed only upside down.

Dishwasher malfunctions: basic troubleshooting algorithm

You have set the dishwashing mode, the indicators are on, the process of feeding and heating the water is on, but its main function is washing dishes and the machine is refused. The reasons for this dishwasher malfunction are as follows:

• Filter clogging. It is located at the bottom of the chamber loading chamber. Eliminate this problem simply: remove the filter, rinse it and put it back on its original place.
• Clogging of injectors. The dishwasher does not spray water. Clean the nozzle holes with an ordinary toothpick. A clogged nozzle may become a cause of low pressure, as a result of which the dishes are not washed properly. Sometimes, if the rocker does not rotate, the problem may be the malfunction of the circulation pump.
• A breakdown of the circulation pump that supplies water to the nozzles is a serious enough failure, which is manifested in the fact that the machine stops collecting water. The only way out is to replace the faulty circulation pump with a working one.

Important! Determine the breakdown of the pump can be by the characteristic sound. If there is no noise after dialing water, then most likely there is a problem in it.

The cause of malfunction of dishwashers in this case may be damage to the winding of the electric motor. Check the integrity of the windings by checking the interturn closure using a multimeter.

Water overflows

Most likely, you are a failure of the water level sensor. Remedy the problem by replacing the sensor with a new one. If the machine is turned off and the water is supplied to the chamber, there is a problem in the solenoid valve, which prevents water from entering. The replacement of the valve with a worker does not cause any difficulties.

Underheating( overheating) of water

It often happens that the machine heats the water too much or vice versa - it does not warm it up. The cause of overheating is the failure of the temperature sensor, which leads to increased vaporization and breakage of the equipment.

Causes of underheating may be as follows:

• Temperature sensor failure.
• Low water pressure - if there is a problem with the injectors or the pump.
• Faulty electric heater - can be checked by measuring the resistance with a multimeter).

No discharge of water

If the water does not drain into the sewage system, the cause of the error in the Bosch dishwashers may be in the pump failure or in the clogging of the drainage system. Sometimes the dishwasher does not completely drain the water. Most likely, the reason is that the drain hose is excessively high and after the pump is turned off some of the water comes back to the chamber.

Case with current

With a probability of 99%, it can be said that a breakdown of the heating element occurred. To verify this, you need to open the heater and carefully inspect it. If there is damage, the heating element is replaced with a new one.

Important! Too often the cause of the heating element failure is too hard water.

No detergent drawer

If the dishwasher does not pick up the washing tablet or powder, the most common cause of the problem is a small water pressure or clogged nozzles. As a result, no water enters the dispenser.

Important! Sometimes, if the valve is broken( water intake does not open), the tablet does not dissolve completely, and the dishes turn out to be poorly washed.

No power

Errors of dishwashers Bosch are manifested in the fact that the technology does not turn on, does not respond at all to the pressing of the button. The causes of the malfunction may be as follows:

• The socket has failed.
• The locking device is burnt.
• The door is not closed.
• The network button is broken.
• Defective mains filter.

Important! To correctly "diagnose", it is necessary to check with the help of a multimeter all the links of the electrical circuit - this will allow to find the breakdown by the method of elimination.

Extraneous noise

The presence of extraneous noise indicates damage to the motor bearings or pump. Most often, bearings fail from wetting with water. Water seeps into the bearings due to damage to the stuffing box. As a result, the technique begins to make a lot of noise during the work.

To completely eliminate malfunctions of dishwashers, you will need to replace not only the bearing but also the stuffing box.

Important! Too loud operation of the dishwasher can also be caused by damage to the pump impeller, from debris entering the impeller.

Drying of dishes

does not work. Some models of dishwashers are equipped with the function of drying washed dishes. Drying is done using a fan that is installed inside the chamber. If the drying does not work, at the same time, all other functions of the technician perform normally, then the problem is in the fan.

To verify this, it is necessary to check the incoming contacts and windings using a multimeter. If necessary, a broken fan is replaced with a working fan.

Water flows to the floor

This is one of the most common breakdowns of dishwashers. The reasons for the flow of water under the hull can be several:

• Bad condition of door seals. Perhaps they need to be replaced or cleaned of plaque.
• The pump seal is damaged. The way out is to replace it with a new one.
• The clamps on the water supply and drain hoses are not tightened sufficiently, there are no seals on the connections of the nozzles.
• The water tank is damaged. Most often, it can not be repaired, the tank is replaced with a new one.

Important! To correctly determine the location of water leakage, the machine cover is removed and the floor is covered with newspapers. The breakdown is on the side where the paper gets wet.

Error codes for dishwashers Bosch, Siemens, Neff, Gaggenau

Bosch dishwashers are equipped with self-diagnosis systems. The owner does not collide with them until mysterious letters with numbers appear on the display. What do they indicate? Here is a brief description, based on which error codes Bosch dishwashers or other brands show your technique:

1. E1.There were problems with heating. There is a high probability that the heating element or the electronic module responsible for its operation is defective.
2. E2.Failure in the operation of the temperature sensor, located in the same unit with the heating element.
3. E3.Problems with water intake. The cause must be sought in the malfunction of the pump, hose or intake filter.
4. E4.Clogged flow switch or blown engine.
5. E5.Exceeding the level of filling with water in comparison with the permissible. The problem may arise due to malfunction of the pressure switch or the intake valve.
6. E6.Defective aquasensor - a device that tracks the stiffness and degree of contamination of water.
7. E8.Inadequate water level in the pan, water self-supply. Often the cause of this phenomenon is not enough strong water pressure in the water pipe, and dishwashing equipment can not be used.
8. E9.Defective heating element. You may need to change it.
9. E11.Problems with NTC module and sensor, power wires.
10. E14.The flow sensor does not receive control pulses.
11. E15.Operation of akvastop due to water leakage. The specific reason for the leak will be determined by a specialist.
12. E16.This error of Bosch dishwashers indicates an unintended set of water. There may be problems with the level sensor, intake valve. Sometimes an error is given in connection with increased foaming.
13. E17.Problems with draining the water.
14. E21.Malfunction of the drain pump due to natural wear or foreign objects entering it.
15. E24.Water does not drain, which can be caused by hose clamping.
16. E27.Undervoltage in the network. The problem can be solved by installing a stabilizer.

Knowing the codes of basic problems will allow you to either promptly eliminate them yourself, or call a specialist in a timely manner. So - the likelihood of further healthy work of such valuable household appliances is much higher.
