Washer-dryer combo door will not open at the end of the cycle, even though the drum has stopped.

Safety first: Do not force the door open. Unplug the unit before attempting manual release.

Steps to release:

• Wait a few minutes: Some models delay unlocking until the drum cools or water level is confirmed low.
• Check for water: If water is visible through the door, run a drain/spin cycle. If the machine will not start, manually drain via the emergency hose.
• Use emergency release: Open the lower access panel and pull the emergency door release cable (if equipped) to unlock the door.
• Inspect lock (advanced): If the problem recurs, access the door lock assembly and check for mechanical damage or loose wiring.

When to stop: Repeated lock failures indicate a faulty door lock or PCB; replacement should be done with correct Samsung parts.
