Miele Washer Error Code F4124

F4124 means the washer detected a drive fault because the drum did not rotate within 3 minutes of the activation signal being sent to the drive motor. The control board monitors drum movement through a tachogenerator on the motor, and if no rotation is confirmed in that window, the machine stops and displays the code. A shorted tachogenerator is specifically identified as a likely cause, along with motor failure, wiring faults, or a physically blocked drum.

A reset may temporarily clear the code, but if the underlying fault is still present, F4124 will return as soon as the machine attempts to run the drum again. The code is triggered by an active hardware failure in the drive or motor circuit, so a reset alone is not a fix. The root cause must be diagnosed and repaired for the washer to operate normally.

Repair costs depend on the component at fault. A tachogenerator replacement is generally the least expensive repair, typically ranging from roughly $80 to $180 including parts and labor. A drive motor replacement is more involved and can range from approximately $250 to $500 or more depending on the model and labor rates in your area. A control board replacement tends to be the most costly option and should only be pursued after other components have been ruled out.

Some causes of F4124 are accessible to a knowledgeable DIYer, such as checking for a drum obstruction, inspecting wiring connectors, or manually testing the tachogenerator coil with a multimeter. However, replacing the tachogenerator, drive motor, or control board involves disassembling the machine and working near electrical components, which is best handled by a qualified technician if you are not comfortable with appliance repair.

No, you should not attempt to run the washer when F4124 is active. The machine has detected that the drum is not rotating, which means laundry will not be washed and the motor may be at risk of overheating if it is attempting to run without movement. Leave the washer powered off until the fault is diagnosed and repaired.
