Error codeF3
ApplianceWasher
Quick answer
F3 is shown on the display of Miele washing machines and washer-dryers. There is a short circuit in the heater bank temperature sensor circuit.
Model compatibility
Miele reuses codes across series and model years, so F3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What thiscode means
Short circuit in the heater bank temperature sensor circuit.
Seeing F3 on a Miele washing machine or washer-dryer? The heater bank temperature sensor circuit has a short circuit, which Miele lists as a technical fault.
Next step
Owners have no remedy here, so arrange a repair appointment through Miele online booking.
Do not mix it up
F3 is a different code from F34 (door lock) and F35 (door release). An electronic module fault has its own code, F39.
