Understanding the Problem
The safety latch (door latch/lock assembly) on a front- or top-load washing machine ensures the door stays closed during fill, wash and spin cycles and prevents the machine from running when the door is open. When the latch fails the washer may refuse to start, stop mid-cycle, show door-error codes, or leave the door locked after the cycle ends. Latch problems are commonly electrical (faulty lock switch or wiring) or mechanical (broken striker, worn catch, or damaged latch gears/springs). Proper diagnosis requires checking for error codes, inspecting the latch and strike for visible damage, and testing the lock switch for continuity or correct voltage before replacing parts.
Common Symptoms
Washer won't start and shows a door/lock error; door stays locked after cycle; machine pauses mid-cycle; no audible lock engagement; intermittent starts or stops tied to door position.
Common Causes
- Failed door lock assembly (mechanical wear or broken internal switch)
- Faulty door striker/catch or damaged door hinge preventing proper engagement
- Wiring harness problem or control board not supplying power to the lock

Helpful Repair Tip
Check the washer's error code or listen for the lock engagement sound at cycle start. If you hear nothing, test the latch with a multimeter for continuity when the door is closed; no continuity often indicates a bad lock assembly.
Frequently Asked Questions
How do I know if the latch or the control board is bad?
Start by observing whether the lock attempts to engage (you should hear a click at cycle start). If there's no sound, test the lock assembly with a multimeter for continuity when the door is closed. If the latch shows no continuity or is visibly damaged, replace it. If the latch tests good but the washer does not send voltage to the lock or shows electrical faults, investigate the wiring and the control board; having a technician measure control voltage can confirm a board failure.
Can I force the door open if it stays locked after a cycle?
Most washers have a manual release accessible through the detergent drawer, a lower access panel, or behind a small service flap — consult your manual. If no manual release is available or you don't know the procedure, disconnect power and wait 5–10 minutes (some machines automatically release after power removal). Forcing the door can damage the latch or door seal — if you're unsure, consult a service tech.
