Siemens washing machines are distinguished by their reliability and high build quality. The manufacturer has taken care of a high-quality self-diagnosis system.

If household appliances break down, then finding out the reason is pretty easy. An error code will appear on the display, which will indicate a problem.

Decoding error codes and their causes

The Siemens washing machine may stop running the program or not start washing at all. In this case, the display shows a code, for example, E21. This is how the technique communicates the results of the self-test. It is enough to decipher the message and take action.

Here are the options for error codes and their reasons.

Error code	Reason and decryption
F01	The washing machine door is not fully closed.
F02	The device cannot draw water to continue the program.
F03	Waste water drainage problem.
F04	A fluid leak has been detected in the system.
F16	The hatch door is not closed.
F17 (E17)	The system noted that it took too long to collect water. This may be due to too low pressure, filter clogging. Sometimes the cause of the error is the lack of water in the plumbing.
F18 (E18)	Draining fluid took longer than planned. This could be due to a blockage in the drain pump or a blocked pressure sensor. Less commonly, an error occurs due to a broken electronic module.
F19	The water takes too long to warm up. The reason for the appearance of the code may be a breakdown of the heating system, scale or breakdown of the heating element. A thermostat can also be achieved so that heating does not stop at the right time. Less often, the water does not heat up due to the low voltage in the mains.
F20	The liquid is warming up, although this should not be so. The system displays an error if a program with a low water temperature is installed, and the heating element continues to work. The reason may be a breakdown of the temperature sensor or heater relay.
F21 (E21)	The appearance of the code signals a breakdown in the control system of the washing machine. Together with the error, you can notice the uneven operation of the motor or its complete absence. The reason may be a breakdown of the tachogenerator or a short circuit in the triacs. The error is critical.
F22	The thermal sensor is out of order.
F23 (E23)	The error signals the activation of Aquastop. The reason is water in the sump. Less often, the code is displayed because the contacts on the connection circuit are burned out.
F25	Broken turbidity sensor - Aqua-Sensor. This happens if the part is covered with scale. Also, a breakdown may appear due to a blockage in the drain or a breakdown of the pressure sensor.
F26	The system noticed a malfunction of the pressure sensor, the pressure switch is broken. This error is critical, therefore the washing machine is completely blocked.
F27	There was a failure in the pressure switch settings.
F28	Broken flow sensor.
F29	The system does not register the flow of water into the tank. This may be due to low head, blockage, valve or pressure sensor breakage. Less often, the reasons lie in the failure of Aquastop.
F31	The system has detected that the water level has been exceeded. The problem can be caused by a problem with the hose, solenoid valve, or water level sensor. It happens that the pressure switch is not tuned. Also, a malfunction occurs due to blocking of the pump, blockage of the drain system.
F34	The hatch is not locked, the locking system is not activated. The reason may be a breakdown of the locking system or the lock tongue. Sometimes the door itself hangs crookedly or the error occurs due to wear of the sealing gum.
F36	The locking system is out of order.The reason is the breakdown of the control module.
F37 F38	The thermal sensor is broken or has a short circuit.
F40	An error occurred while syncing.
F42	The motor is running too fast. The reason is a triac breakdown or a failure in the system board. The error is considered critical.
F43	The motor does not work, does not turn. There may be something stuck between the tub and drum. In more serious situations, the error is associated with a breakdown of the tachogenerator or control unit, engine blocking.
F44	The drum rotates in one direction only. The reason is the breakdown of the triac, relay or control module. The error is critical, the washing machine is blocked by the system.
F59	The 3D sensor is out of order. Sometimes it happens due to a failure in the system. Also, the reason may be a break in the wiring, breakdown of the drain module or the sensor itself.
F60	Broken flow sensor. Also, the code is displayed if there is turbulence in the branch pipes of the part or in it itself.
F61	The system fixes erroneous commands from the hatch door. The problem is critical, the washing machine is blocked.
F63	There is a problem with functional protection. The reason is processor failure or software failure. Critical error, the technique is blocked.
F67	There is a problem with the encoding of the card. The error is critical. Accompanied by a blocking of the washing machine.
E02	The problem lies in the motor. The reason for the occurrence of the code is in a violation of the resistance of the motor or in the malfunction of modules, contacts.
E67	A failure has occurred in the coding of the control system. This could be due to a firmware failure. The error is critical.

Elimination

You need to take action based on the malfunction. For example, if a breakdown F04 is displayed, then you need to find and eliminate the leak. If you need to unlock the control panel to solve a problem, you can restart the washing machine.

It is important to first turn off the power using the button, then unplug the power cord from the outlet.

Eliminating common mistakes:

If there is a problem with the hatch door, then first you should make sure that the clothes do not interfere with the closure. Then the blocker system is inspected for damage. Also, the door may not close due to wear on the hinges or the elastic of the seal. It is worth checking these parts and replacing them if necessary.
To eliminate error F02, check if there is water in the pipes, if the supply valve is not closed. If everything is in order, then it is worth inspecting the hose and filters. There is probably a blockage somewhere - you just have to remove it for the code to disappear.
The F03 code must be corrected sequentially. Filters are inspected first and cleaned if necessary. Then you should check the drain pump for defects. If the pump is broken, you should contact the service center. You will also have to call the wizard if the breakdown lies in the control module.
If Aquastop breaks down (error F23), the contacts should be checked and replaced if necessary. If there is no breakage in the wires, then the sensor itself should be examined. The part will have to be changed if it is out of order.
If any sensor is out of order, then first you need to check its contacts. If everything is normal with them, then you should inspect the part itself for defects. If any, the sensor should be replaced with a new one.
To eliminate error F31, you need to check the inlet valve and drain pump, pressure sensor. If all parts are normal, then you should find and remove the blockage in the drain system. It happens that such simple actions do not help. So the reason for the error is in the wiring. We'll have to change the wires.
If synchronization fails (F40), it is enough to restart the washing machine. If this does not help, then you will have to call the master.
To eliminate F67, it is necessary to restart the technique and re-encode the card. If this does not help, then you will have to replace the part.

It is highly discouraged to eliminate critical errors on your own. Incompetent repairs can lead to the fact that the equipment will become completely inoperative.

You should immediately contact the service center and call the wizard. You can only deal with typical, minor breakdowns on your own.

Advice

Siemens washing machines are distinguished by their reliability and long service life. Appliances will work flawlessly with proper care.

Here are some basic tips.

Tap water should be softened for washing. For this, special filters or powders are suitable. In this way, it will be possible to avoid the formation of scale on the heating element.
Before starting washing, check all pockets of items so that small items do not get into the washing machine. They can cause serious damage to sensors, drum and even motor.
The hoses and filters should be inspected every six months. EIf there is a blockage, then the parts should be removed and rinsed with running water.
It is recommended to clean the detergent drawer and drum once a month.
Do not overload the equipment. Operating under maximum load will lead to rapid wear on the motor and other parts.
Do not leave the door of the washing machine open for a long time. Moreover, you cannot put things on it. This will lead to rapid wear of the hinges, the hatch will stop closing.
