Siemens washing machine informs the owner about breakdowns, displaying error codes on the display. If you know what this or that code means, then in half the cases you can fix the problem yourself without calling the wizard.
If you have lost the user manual, or it does not provide a decryption of codes, or a book in English, our table will come in handy. We have collected in one place all the possible fault codes that the Siemens washing machine displays on our display.
Legend:
Short circuit - short circuit.
THAT - maintenance.
Software - software.
To remove the error, you need to check how tightly the door is closed.
Try packing the laundry differently, making sure that they do not interfere with the normal closing of the door.
- Is the tap for supplying water from the water supply system to the AGR open?
- Make sure that there is water in the water supply and whether it has sufficient pressure.
- Is the water intake hose blocked?
- Is the filter screen at the water inlet of the MCA blocked?
- Inspect the filter for clogging, make sure that there are no clogs in other elements of the drain system.
- Check if the pump (drain pump) is working properly.
- Check if the impeller of the pump rotates freely. In both directions, it should rotate equally freely. Measure the resistance of the pump coil, if it is working, then the indicator should be 200 Ohms. If the pump is broken, it must be replaced.
- Make sure the electronic module is working.
- If the mode does not start, restart the wash.
- Close the door tight.
- Replace UBL.
- Water tap shut off.
- The filter mesh of the water inlet valve clogged.
- The water pressure was less than 1 bar.
- Unscrew the valve if it is closed.
- After that, the cycle will stop. Water will merge within 5 minutes.
- A restart of the program is possible.
- The drain pump is broken or clogged.
- Not reached level N1.
- The pressure sensor switch is locked.
- Broken electronic unit.
- Clean the drain pump (pump).
- If the drain is not one and a half minutes, the cycle is canceled, and the machine will go into critical error mode.
- Call the wizard.
- The water heating system has failed.
- The thermostop was not reached (heating did not stop at the right time).
- The voltage on the network is not high enough.
- Scale on the heater, or the heater has broken.
To fix the breakdown yourself, check the heater and its connection circuit. Call him a tester.
If the heater is broken, it needs to be replaced.
In all cases, the program ends with cold water.
Error F20 indicates a sudden heating of water. You select the program at low temperature, and the heater still heats the water.
The reasons:
- The temperature sensor is broken.
- Thermal heater relay failed.
F21 talks about the breakdown of the CM control system. It is accompanied by uneven operation of the electric motor, or the motor does not rotate the drum at all.
This could mean:
- KZ triacs.
- Damage to the tachogenerator.
- Damage to the reverse relay.
F22 is a breakdown of the temperature sensor.
- Check the integrity of the contacts, replace the damaged areas.
- Check the health of Aquastop.
- Scale collected on the sensor.
- The pressure sensor has broken.
- The drainage system is clogged.
With an F25 error, the wash will end without rinsing.
First, clean the drain system. If the sensors are broken, replace with new ones.
The error is critical, therefore, it is accompanied by such behavior of the washer:
- The cycle stops.
- The pump pumps out the remaining water.
- The hatch is locked.
- The buttons that control the processes and indicators of the control panel are locked.
To reset errors, do the following:
- Turn off the CM.
- Check sensor.
- Perform maintenance wiring.
If the pressure switch is operating at the old values due to the fact that it was not configured, it is necessary to check the sensor itself and its wiring.
Replace damaged wire sections or the sensor itself.
The flow sensor does not record the flow of water, which is why F29 appears.
This may occur because:
- Water tap shut off.
- Pressure below 1 bar.
- Clogged filter installed on the water intake valve.
- Damage to the valve.
- Aquastop breakdown.
- The pressure sensor is broken.
The failure is accompanied by a stop of the washing process, draining after 5 minutes, restarting the cycle.
To resolve the error, first try opening the water supply valve.
In more serious cases, you need to check the components indicated on the right and the wiring to them, replace with serviceable parts, or conduct maintenance on the wires.
- Blocked pump.
- The drain hose is clogged or bent.
- The solenoid valve has broken.
- The pressure switch is not configured.
- The level sensor has broken.
- The drainage system is clogged.
- Bay valve.
- Drainage pump.
- Pressure meter.
- The drain system is a fact of clogging.
- The integrity of the wires.
- Damage to the blocker.
- The locking tongue is biased.
- The door itself is stuck.
- The elasticity of the sealing gum was broken.
This is a critical mistake!
Accompanied by the abolition of the wash cycle, blocking the hatch, blocking the control panel.
To fix the failure:
- Turn off the machine with the button on the panel.
- Check for UBL.
- Check the mechanical component.
- Perform wire maintenance.
F36 is a critical mistake! The machine does not respond to commands.
Reset the error by disabling the AGR from the button. Check the control module for serviceability.
Maintenance wiring is required.
F37
F38
- The temperature sensor has broken.
- Short circuit sensor.
- Sensor breakage.
- Wires for integrity.
F42 is an important mistake. The machine does not respond to user commands.
To reset the error, a test program and an electronic unit check are required.
The motor does not spin.
In the simplest case, things are stuck in the space between the drum and the tank.
In more severe cases, there is a risk of such breakdowns:
- The tachogenerator broke.
- Engine or drum blocked.
- The control unit has broken.
F43 - also a critical mistake! It is accompanied by the fact that the machine does not respond to manipulations with the control panel.
Run a service test and check
- the drum is not overloaded;
- Is the tachogenerator broken?
- whether the electronic unit is out of order;
- whether the integrity of the wires is broken.
With F44, the machine is locked. Requires the launch of a test program and verification of the electronic unit.
- Problems with the control board.
- Engine malfunction.
- Diagnostics of the control board. Repair, firmware or replacement.
- Inspection, repair or replacement of the engine.
- The integrity of the wiring.
- 3D sensor.
- The location of the magnet.
- Electronic module.
- Sensor.
- Filter mesh on the water intake valve.
- Electrical wiring.
- The door is open or closed.
- Security lock activated.
This is a critical error code, followed by a blocking of the CMA control panel.
To reset the code:
- Reboot the washer.
- Check the condition of the blocker, the mechanical part, the wiring.
Another critical error with blocking the CM control panel.
Reboot the machine, check the power unit.
F67 means an error in the encoding of the card.
- Reboot the machine.
- Recode the card.
- In case of unsuccessful encoding, the card must be reinstalled.
The problem of the electric motor.
- Engine resistance.
- Contact Integrity.
- Module health.
Failure in control board encoding.
E67 code may indicate a firmware failure. You need to contact a specialist to reprogram the unit.
In severe cases, module replacement will be required.
Now you know what each of the possible mistakes of Siemens washing machines means. The main thing is to recognize the malfunction in time in order to fix it yourself.
In difficult cases when repair or reprogramming of the control board is required, we advise you not to save money and consult a specialist.
