The main malfunctions of dishwashers

In most cases, the causes of dishwasher breakdowns and how to fix them do not depend on the brand of equipment. It’s Bosch or Electrolux, or maybe Beko – it doesn’t matter. The repair will be almost the same. Only some processes differ – disassembly, mounting method, etc. Otherwise, the repair is universal. Let’s take a look at common causes of malfunctions, preventive measures, and the benefits of professional dishwasher troubleshooting.

The following are the most common breakdowns that many people try to fix on their own:

Doesn’t turn on

The first thing to do is to check the wiring, plugs, and sockets. Damage to these elements can lead to a shutdown of equipment or a short circuit. If defects are found in the socket or plug, you must replace them yourself or use professional help.

The cause can also be a network filter malfunction. It is located inside the case. Damage and burnout of the contacts in this element can lead to a shutdown of the equipment or cause the machine to operate in the shield. In addition, the technique can be shocked. The filter can only be replaced – it cannot be repaired.

The reason that the dishwasher does not turn on may be the chafing of the wires inside the case. It is difficult to fix the malfunction on your own, because you need to disassemble the equipment.

Not heating or overheating

In this case, the most common reason is the heating element burned out. To check if this is the case, you should remove the back wall and inspect the heating element. It is also recommended to call him. If the element is burned out, it needs to be replaced.

Another reason that the equipment does not heat up lies in the failure of the contacts on the control board. In this case, the on-board computer does not transmit a command for heating. Sometimes it is possible to restore working capacity by mechanically cleaning the contacts.

There are other causes of the malfunction – a malfunction of the thermostat or temperature sensor. To detect a problem, you first need to disassemble the machine, and then test the elements.

Doesn’t drain or take in water

These problems are among the most common. The reasons that the equipment does not drain water can be:

  • clogging of the garbage filter – you can clean the element yourself;
  • failure of the drain pump or failure of the element – only the replacement of the part can fix the trouble;
  • clogging of the “snail” pipe with large debris – cleaning is required.

If the equipment does not fill with water, then the cause of the malfunction may be hidden in the operation of the overflow protection. If the problem recurs frequently, then a call to the wizard is necessary. It is possible that the water is not draining due to a burnt out valve, which also requires professional help.

Prevention of PMM breakdowns

In order to avoid damage as much as possible, you should:

  • clean plates and cups of food residues before loading;
  • do not overload the equipment;
  • do not forget to regularly clean the elements of the machine;
  • degrease dishes with professional products;
  • load the lower basket with the dirtiest dishes and start unloading after drying from it.

Professional dishwasher repair

No matter how simple the repair may seem, do not neglect the help of a wizard for diagnosing and troubleshooting. And in some cases, independent attempts to fix the problem in the operation of the equipment can lead to its final breakdown.

Only a professional can accurately determine the cause of a malfunction and take the correct actions to eliminate it.
