How to Fix / Troubleshooting
Safety first: Disconnect power before attempting to free a jammed lock. Beware of sharp metal edges.
- Check door position: Ensure the door is fully closed. Gently press on the door while starting a cycle to see if the error changes.
- Listen for lock movement: If the motor hums but the lock does not move, the mechanism may be jammed.
- Manual release (technician): Remove the top panel and locate the lock assembly. Use the manual release lever (if fitted) to open the door.
- Test switches: With a multimeter, check continuity of the lock position switches while operating the lock. Replace the lock assembly if switches are faulty.
