Appliance Washer
Quick answer

F103 on a Miele washer or washer-dryer points to a fault with the M-Bus module, which the owner cannot remedy.

Model compatibility

Miele reuses codes across series and model years, so F103 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
