How to Fix / Troubleshooting

Safety first: Disconnect power. If the door is locked with clothes inside, do not force it open; damage may result.

Wait for cool-down: Some models keep the door locked until the drum temperature is safe. Wait 5–10 minutes after cycle end.
Emergency release: Check the user manual for an emergency door release (often a pull cord behind the lower front panel).
Inspect door lock: Remove the front panel trim to access the door lock assembly. Check for broken plastic parts or signs of overheating.
Test lock coil: Disconnect the lock and measure resistance across the solenoid coil. An open circuit indicates a failed lock.
Check wiring: Verify continuity from the lock connector to the main control board. Repair any damaged wires.
Replace lock assembly: If the lock is defective, install a new Liebherr door lock assembly and test operation.

Dryer shows F17; door may not unlock at end of cycle or may not lock at start.
