What the F104 Fault Code Means
The F104 fault code indicates that the voltage reaching the motor drive circuit is lower than required for safe operation. Modern Miele washing machines are sensitive to voltage fluctuations and will stop the cycle if the drive voltage falls below an acceptable threshold, to protect the motor and electronics from damage.
Common Reasons This Fault Appears
Low mains voltage
A drop in household mains voltage — which can occur during periods of high demand on the local electrical network — can cause this fault to appear.
Faulty extension lead or socket
If the machine is connected via an extension lead or a faulty wall socket, the voltage reaching the appliance may be insufficient.
Overloaded household circuit
Running multiple high-demand appliances on the same circuit simultaneously can cause voltage to drop enough to trigger this fault.
Internal power supply fault
A fault within the machine’s own power supply or drive electronics can cause low voltage to be reported at the drive circuit.
Safe Checks You Can Try
Check the power supply
Ensure the washing machine is plugged directly into a dedicated wall socket rather than an extension lead or multi-socket adapter.
Check other appliances on the circuit
If other high-demand appliances are running on the same circuit, try running the washing machine alone.
Restart the washing machine
Switch the machine off at the mains and leave it unplugged for at least 2 minutes. Reconnect the power, switch back on and restart the programme. If the voltage issue was temporary, the error should clear.
Miele advises that if the fault persists after a reset, the appliance cannot be repaired without professional assistance.

When To Contact A Professional
If the F104 fault persists and is not related to a temporary mains voltage issue, an electrician should check the household wiring and socket. If the fault lies within the appliance’s drive electronics, a qualified engineer will need to inspect and repair the internal power supply components.
Internal components should only be inspected or repaired by trained professionals.
