Quick answer

F120 on a Miele refrigerator display means the mains voltage is occasionally too low or fluctuates a lot.

Model compatibility

Miele reuses codes across series and model years, so F120 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
