Possible Causes
How to Fix / Troubleshooting
Safety first: Unplug the unit before attempting to free a stuck door lock. Avoid forcing the door open.
Steps to troubleshoot:
- Attempt gentle release: After unplugging, wait a few minutes and then gently pull the door. Sometimes the lock releases after power is removed.
- Access emergency release: Many Samsung combos have an emergency door release cable near the drain filter access. Pull it gently to unlock the door.
- Inspect lock assembly: Remove the door boot clamp and peel back the gasket to access the lock. Check for broken plastic parts or obstructions.
- Reseat connector: Ensure the lock's wiring connector is fully seated.
When to stop: If dF persists or the lock is physically damaged, replace the door lock assembly. If a new lock does not resolve the issue, the PCB may be defective.
