How to Fix / Troubleshooting
Safety: Ensure the oven is cool. Disconnect power before working on the lock mechanism. Do not force the door open during a hot self‑clean cycle.
- Check for obstructions: Inspect the door latch area for bent metal, foreign objects, or misaligned strike plates.
- Manual release: Some Miele models have a manual door lock release accessible behind the front panel or through the top. Consult the service documentation to safely release the lock.
- Test lock motor: Access the door lock assembly from the top or rear. Check the motor connector and microswitches. With power applied and extreme caution, start a lock cycle and listen for motor operation.
- Continuity checks: Test the lock position switch for proper open/closed states when the latch is moved by hand.
- Replace assembly: If the motor is inoperative or the switch is defective, replace the complete door lock assembly.
