What Does Error Code F34 Mean on a Miele Washing Machine?

Door lock fault — door will not lock.

F34 fires when the control board cannot confirm the door interlock has electrically latched during the pre-start check. Because the drum must stay sealed before filling or spinning, the machine blocks the cycle rather than risk an open door. The most frequent cause is a door not pushed fully home; beyond that, a worn or failed interlock solenoid, or damaged wiring between the board and lock. It differs from F35, which points to the lock circuit not releasing or a control-side fault rather than a failed engagement.

Models affected: Miele W1 Series front-load washers, and broadly Miele front-loaders that use an electronic door interlock
What owners report: Owners commonly report F34 appearing right at cycle start, often after laundry or a bit of the rubber seal is pinched in the door. A firm push until it clicks, plus a brief power-off reset, resolves it in many cases; if the code persists with the door clearly shut, the interlock has usually failed.
