If you encounter problems with your Siemens washing machine, it is not necessary to immediately call the wizard. A modern self-diagnosis system allows you to quickly determine the cause of the malfunction.
Having found out it, you can try to repair or replace the element in the Siemens washing machine yourself.
Fault codes CMA Siemens
Before proceeding with the repair, we will analyze the error codes of the Siemens washer. Their values will tell you where to look for a breakdown.
| Error Codes | Value |
| F01, F16 | The door is not tightly closed. |
| F02 | No water is drawn. |
| F03 | No water drain. |
| F04 | A leak has occurred. |
| F17 | The water has not reached the minimum level in a certain time. |
| F18 | A timeout has elapsed, no water is being drained. |
| F19 | During the allotted timeout, the water did not heat up. |
| F20 | There was an unexpected heating of the water. |
| F21 | The engine is not working correctly. The main module has failed. |
| F22 | Damage to the thermostat. |
| F23 | The Aquastop system worked. |
| F25 | The turbidity control sensor has failed. |
| F26 | There is a problem with the pressure switch or with the additional pressure sensor. |
| F27 | Incorrect setting of the pressure switch or pressure sensor. |
| F28 | The flow sensor is not working. |
| F29 | The flow sensor is clogged. |
| F31 | The water is too high in the tank.. |
| F34 | Door lock defective. |
| F36 | There is a problem with the door locking system. Malfunction of the electronic module. |

Typical faults
Consider the breakdowns that most often occur, as well as the possibility of repairing Siemens washing machines with your own hands.
Clogged drain tract, pump malfunction in a Siemens machine
Poor drainage of water after washing or its complete absence indicate a blockage in the drain pipe or filter, a pump failure – in 30% of cases.
The pump in the Siemens washing machine is located behind the front panel. Therefore, to get to it, you have to work hard:
Check the nozzle and pump for clogging. To clean, just remove the nozzle and rinse under running water.
To remove the pump, disconnect the connectors and unscrew the fixing bolts.
Problems with the inlet valve CM Siemens
If you notice that the washer does not fill or pour water, the intake valve is probably broken. Do-it-yourself repair and replacement of the valve in a Siemens washing machine:
- Disconnect the intake hose from the SMA.
- Remove the rear screws and remove the top panel.
- Disconnect the valve coil connector wires.
- Remove the hoses leading to the valve.
- At the back of the housing, unscrew the two bolts that secure the valve. Get it out of the car.
You can install a new element in the reverse order.
No water heating, failure of the heating element in the Siemens car
Heating element malfunctions – 15% of all breakdowns of Siemens machines. The reason for this is scale or a short circuit. Scale prevents the heat from being transferred to the heater, so it overheats and burns out.
Having reached the heating element in the Siemens washing machine, check it with a multimeter before replacing it.
To get the heating element, remove the front panel of the SM, as described above. Attach the multimeter probes to its contacts and check the readings with the photo.
In the event of a malfunction, replace it yourself:
- Disconnect all wires.
- Loosen the central nut, push the bolt inward.
- Prying off the edges, remove the element.
- Install the correct heater in reverse order.
Water leak in a Siemens washing machine
Water leakage problems account for 10% of all breakdowns.
Leakage occurs due to depressurization of the seams or damage to parts and connections. The hatch cuff may also be broken or worn.
Let’s tell you how to replace the cuff on a Siemens washing machine with your own hands:
- Open the hatch door.
- Having unbent a rubber cuff, pry off a metal collar with a screwdriver.
- Carefully remove the clamp, then remove the front body of the machine.
- Disconnect the tube leading to the cuff.
- Record the cuff.
Inspect the cuff at the time of damage: is it possible to repair it, patch up the gaps. If not, then a new part is installed.
Worn brushes, motor failure
Another 10% of breakdowns are problems with the washing machine motor. At the moment of a short circuit, the motor winding could burn out, and the commutator brushes could also wear out.
How to make self-repair and replace electric brushes:
- Remove the top and back covers of the CM by unscrewing the bolts.
- Remove the belt from the motor pulley.
- Disconnect the wiring.
- Unscrew fixing bolts.
- After removing the motor, slide the terminal plate and pull out the brush.
After dismantling, inspect the brushes: if they are too worn, it is better to install new elements. Then reinstall the motor on the Siemens washing machine.
It happens that electronic components fail: the electronic board and its components. This is a complex repair, which is not always possible for a beginner. To understand the issue, you will need the wiring diagram of the Siemens washing machine.
We recommend contacting a service center if the board breaks down – do-it-yourself repair in this case is not justified and can only do harm.
