Error code F55
Appliance Wall Oven
Quick answer

F55 appears when a Miele oven shuts itself off after running unusually long. Turning it off and on restores use.

Model compatibility

Miele reuses codes across series and model years, so F55 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 this code means

Oven switched itself off after unusually long operation (6 hours in grill modes, 12 hours in others).

Why F55 appears

Miele ovens have a safety cut-out for very long operation. Grill modes allow up to 6 hours, every other mode 12 hours. After that the oven turns itself off and shows F55.
