ApplianceWasher
Quick answer
F34 (Door lock, call Customer Service) means a Miele washer door could not be locked, or the drum on a top loader could not be locked.
Model compatibility
Miele reuses codes across series and model years, so F34 / Door lock 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
Door (or drum on top loaders) cannot lock; the drum is overloaded or there is a technical fault.
Miele washing machines can show F34 with the text Door lock, call Customer Service, or The door will not lock. In plain terms, the door could not be locked, or on a top loader the drum could not.
Overloaded drum
Keep the load within the maximum size in the operating instructions, then turn the machine off and on once.
Technical fault
Isolate the washer from the electricity supply: pull the plug at the wall, or disconnect the fuse.
Wait no less than 2 minutes.
Reconnect and switch on.
If the fault stays, Miele Customer Service or an online repair appointment is the way forward.

F35 is the reverse, a door that will not unlock. A washer standing out of level is F37.
