Samsung Washer Door Won't Open: Locked After Cycle, Mid-Cycle, or Power Outage

Quick Answer

Samsung front-load washer doors lock during the cycle and should unlock 1-3 minutes after the cycle completes. If the door stays locked: after a normal cycle, wait 3 minutes (the PTC lock element needs time to cool). If still locked after 5 minutes, the door lock assembly PTC has failed ($30-60).

Samsung front-load washer doors lock during the cycle and should unlock 1-3 minutes after the cycle completes. If the door stays locked: after a normal cycle, wait 3 minutes (the PTC lock element needs time to cool). If still locked after 5 minutes, the door lock assembly PTC has failed ($30-60). After a power outage mid-cycle, water may still be in the drum - the door won't unlock until water is drained (safety feature). Drain through the pump filter emergency hose to release the water and unlock the door. Samsung also has a manual door release: pull the orange tab inside the pump filter access door on some models, or pull the emergency release cable at the bottom of the door through the gap.
