Siemens Washing Machine Error Codes — E18, F21, F23, E57 Explained

Siemens represents the finest German engineering in Azerbaijan's premium appliance segment. Part of the BSH group alongside Bosch, Siemens washing machines display error codes with E or F prefixes. Guven Service explains all Siemens error codes.

Motor Errors

Code	Issue
E02	Motor error — the motor is not functioning correctly.
E21 / F21	Motor control error — unstable rotation, tachogenerator signal failure.
E57	Inverter motor error — high current detected in the inverter module.

Siemens inverter motors are managed by sophisticated electronics. Unqualified intervention can destroy the entire motor module. Only a Siemens-trained technician should handle these repairs.

Door Errors

When Aquastop triggers, immediately turn off the machine and close the water tap. System reactivation must be done by a technician.
