Modern Siemens washing machines have a built-in self-diagnosis system that allows them to detect a malfunction and notify the user about it. To do this, the equipment displays a numerical-alphabetic error code on the screen or reports the type of failure by flashing indicators in a certain order. To decipher the error codes of Siemens washing machines, you need to use the instruction manual. Having found out what kind of malfunction happened to the equipment, the owner of the device will be able to understand whether it is possible to fix the breakdown on his own or whether it is better to turn to professionals.
Error codes for Siemens washing machines
When a Siemens washing machine breaks down, it can display the following codes on the screen:
F01
This error indicates that the hatch of the Siemens washing machine is not closed or is not closed tightly. It is necessary to close the door again and make sure that the laundry does not interfere with the closing of the hatch.
F02
Error code F02 means that water is not being drawn. You need to make sure that the tap in front of the Siemens washing machine is open, water is supplied at the required pressure, and then disconnect the inlet hose and inspect it and the incoming filter for debris.
F03
This error code indicates that the drain is not working or the water is slowly leaving the tank.You need to inspect the drain filter, clean it of dirt and small objects - buttons, coins, etc. Next, you should disassemble the pump, remove the impeller and remove threads, hair and other debris from it. After this, you need to take a multimeter and run diagnostics of the pump in resistance mode. A working node will show a value of 200 Ohms. Otherwise, the element must be replaced. If the fault cannot be detected, you will need to diagnose the control board of the Siemens washing machine.
F04
This error code indicates a water leak. It is necessary to find the location of the fluid leak. To do this, hoses and pipes are checked, and the tank is inspected for holes.
F16
This code indicates that the sunroof is not closed. You need to turn off the Siemens washing machine, wait a little, then turn it on, close the door and turn on the program again. If the error repeats, you need to diagnose the UBL and replace the faulty unit.
F17
This error code indicates that water is not being drawn or that the liquid is being filled very slowly. The reasons may be low pressure, a closed water tap, or a clogged filter mesh installed on the liquid intake valve.
F18
Draining takes longer than it should. It is necessary to inspect the pump for serviceability and blockages, diagnose the pressure switch and pressure sensor, as well as the system board.
F19
Error F19 reports that the water in the Siemens washing machine does not heat up within the allotted time period. The reason may be a low voltage, a broken or scale-covered heating element, its contacts or wires. It is necessary to install the stabilizer, check the heating element, clean it from lime deposits or replace it.
F20
The water heats up more than required.The heating element relay or the temperature sensor may be faulty. It is necessary to ring and replace the faulty module.
F21
Error in the Siemens washing machine control system. The motor may not be working properly or is not rotating the drum. It is necessary to inspect and ring the tachometer, reverse relay, control triacs, and also to diagnose the motor.
F22
This error indicates that washing is taking place without heating. The temperature sensor may be broken or the wiring is torn. It is necessary to carry out diagnostics and replace the unit or restore the circuits.
F23
This error appears because water has entered the tray and the Aquastop system has been triggered. This indicates leaks or a break in the circuits of the protective system. It is necessary to check the chain links, make sure that the leak protection is functioning properly, and inspect the Siemens washing machine for water leaks.
F25
Rinsing is not performed. This is a signal that the Aqua Sensor (turbidity sensor) is broken or covered with limescale. The second reason for the malfunction is debris in the drainage system.
F26
A problem with the pressure switch or with the sensor that protects against voltage errors. It is necessary to diagnose the sensors and wiring, if necessary, replace the faulty unit.
F27
Error F27 means that the pressure switch is broken. You need to check the part and replace it with a working one.
F28
Error code F28 notifies that the water flow sensor provides incorrect data. You will need to check the wires and diagnose the device.
F29
The flow sensor does not detect liquid entering the tank. The reason lies in low pressure or a blocked water supply, a clogged filter mesh, a broken intake valve, a water level sensor or the Aquastop system. It is also necessary to inspect the wires leading to the listed units.
F31
Error code F31 tells you that there is more water in the tank than there should be. This indicates a possible pump malfunction, broken wires, clogged drain system, broken water level sensor or liquid intake valve.
F34
After closing, the door of the Siemens washing machine does not lock. The mechanical elements of the lock may be faulty, the hatch locking device may be broken, or the wires may be broken.
F36
The lock system is broken. The triac or relay is faulty. You also need to check the wires.
F37 and F38
These two codes indicate problems with the temperature sensor (NTC). There may be a short circuit. The Siemens washing machine finishes the wash in cold water. It is necessary to diagnose the sensor and subsequently replace the unit.
F40
Synchronization error. The electrical network has unacceptable parameters for powering the Siemens washing machine. You need to check the wiring.
F42
The engine runs uncontrolled and at high speeds. The control triac may be damaged or the system board may fail.
F43
Error F43 indicates that the Siemens washing machine motor does not rotate. The reason may be a broken tachogenerator, laundry stuck between the water tank and the drum, a blocked motor or drum, a faulty control triac or system board. It is also necessary to inspect the wiring for breaks.
F44
The drum rotates only unilaterally. It is necessary to diagnose the central board, control triac, and reverse sensor.
F59
Error F59 indicates problems with the 3D sensor or power module. You should check the wiring, 3D module, power sensor.In some cases, a SoftWare error appears; in such a situation, you need to diagnose the system board and make sure that the magnet is positioned correctly.
F60
The water flow sensor is damaged: it displays an underestimated or, conversely, an overestimated value. Turbulence may have occurred in the nozzle or in the module itself. It is necessary to inspect and test the sensor, check the filter in the water intake valve and the wiring.
F61
The code indicates a door error. Perhaps the hatch is not closed completely or is completely open, or the safety lock has worked. It is necessary to check the lock, its mechanical elements and wiring. If everything is in order, you need to restart the Siemens washing machine and close the door more tightly.
F63
This error indicates that a functional security failure has occurred and has locked the control panel. The malfunction could have occurred due to a software error or due to a processor failure. You need to unplug your Siemens washing machine, wait 15 to 20 minutes, then start it again. If the code remains illuminated, you need to check the central control unit.
F67
Notification about errors in card encoding. The issue may be incorrect coding between the power and central modules, or inappropriate software between these same nodes. It is necessary to perform the encoding correctly or install a new card.
E02
This code indicates a malfunction in the Siemens washing machine motor. It is necessary to inspect the assembly: contacts, brushes, windings, as well as the central board. If a malfunction is detected, the part must be repaired or replaced.
E67
The control board is incorrectly coded. You need to reprogram the unit and update the firmware. Sometimes a unit needs to be replaced.
Conclusion
If a Siemens washing machine breaks down, it notifies you of the malfunction using a numerical-alphabetic code on the display. For equipment without a screen, the error code is transmitted by blinking indicators. Siemens washing machines without a display are equipped with several different types of control panels, each of which displays a message differently. To determine how to read the code correctly, you need to refer to the user manual. To decipher Siemens error codes, you must use the instructions. The owner of the equipment can fix most faults on his own; only in a few cases does he need to turn to professionals.
