If your Siemens dishwasher has stopped and issued a malfunction code on the display, do not panic. So the self-diagnosis system reports a possible breakdown. The value of the code will help you determine exactly the reason for stopping the PMM.
Below in the table we presented all the errors of Siemens dishwashers. You will learn their decryption, and you can also fix the problem yourself.
Error codes may appear due to serious breakdowns of the dishwasher, or may be due to a malfunction in the system. To fix it is simple, just restart the equipment.
If the code is reset, then nothing serious has happened, you can continue to work in the usual mode. But if the error is highlighted again, then you will have to understand its causes.
Sometimes even minor troubles can cause the dishwasher to stop. Therefore, before calling the wizard, figure out the reasons: perhaps you will do the repair yourself.
1. The heating element does not function.
2. The control triac on the electronic board burned out.
3. The thermostat is defective.
4. Incorrect operation of the pressure switch.
1. Check heater. For this, the TEN contacts are called with a multimeter.
2. Diagnose the control board. Repair or replace an item.
3. Inspect the temperature sensor. Install a new part in the event of a malfunction.
5. Replacing the pressure switch.
Why the breakdown happened:
1. Clogged filling system: hose, filter, valve.
2. The inlet valve is broken.
3. The drain pump does not pump water. It may be blocked.
4. Damage to the pressure switch.
How to do it yourself:
1. Check and remove blockage in the inlet hose. Disconnect it from the housing and pull out the filter mesh. Clean the filter from debris.
2. Inlet valve diagnostics.
3. Inspection of the impeller of the pump. Elimination of extraneous elements.
4. Change of pressure switch.
What caused the breakdown:
1. The switch is clogged, so it cannot direct the flow.
2. The motor controlling the switch does not work.
How to fix the situation:
1. Inspect the switch, and remove the blockage.
2. Repair or replacement of the Siemens dishwasher motor.
What happened:
1. Incorrect data from the pressostat.
2. The pressure switch tube is clogged.
3. Problems with the intake valve.
1-2. Inspection of the pressure switch, cleaning the tube or installing a new tube.
3. Inlet valve diagnostics. Its coils are checked with a multimeter. If you have problems, you need to install a new item.
Why does the heater fail:
1. As a result of a short circuit, the contacts of the heating element broke.
2. The heater itself burned out.
What can be done:
1. Inspect the wiring of the heater. Change burnt items.
2. Ring the contacts of the heater to check the performance.
What happened:
1. The thermostat is defective.
2. Broken sensor wiring.
3. There were problems in the operation of the control module.
Self repair:
1. Install a working thermostat.
2. Repair wiring.
3. Diagnostics of the electronic module.
How to proceed:
1. Check the connection.
2. Install serviceable parts.
It is necessary to detect the leak and block the leak. What to inspect:
1. Tank PMM.
2. The tightness of the inlet and drain hoses, as well as their connections.
4. Hopper door seals.
1. Mechanical failure of the inlet valve causes the diaphragm to not close.
Therefore, the flow does not stop.
2. The level sensor gives incorrect readings.
3. Exceeded foam level.
1. Put a serviceable filling valve.
2. Change the level sensor.
3. Remove excess foam. Use another detergent or use less.
1. The sensor requires replacement.
2. Check pressure, wait until normal flow resumes.
1. Blockage in the impeller of the pump.
2. Damage to the drain pump.
How to proceed:
1. To eliminate blockage in the dishwasher, empty the hopper from the trays and remove the filter. Open the pump cover and remove anything that interferes with normal operation.
2. Ring the pump contacts with a multimeter. Replace if there is a problem.
What became the reason:
1. Failure in the electronic module of the dishwasher.
2. Wiring or contacts between the board and pump are broken.
3. The pump itself does not work.
1. Diagnostics of the control board.
2. Inspection of contacts for damage. Repairs.
3. Check the pump.
These are the main causes of malfunctions in Siemens dishwashers. So that they serve for a long time, carry out prophylaxis from blockages, clean dishes thoroughly from food debris. Equally important is the proper installation of the dishwasher, the protection of its electronic part from voltage surges.
