Understanding the Problem
The washer safety latch (also called the lid latch, door lock assembly, or interlock) prevents the machine from starting or spinning when the door or lid is open. When the latch fails the washer may refuse to start, stop mid-cycle, fail to spin or drain, or display a door-related error code. The latch can fail electrically (lock motor or switch), mechanically (broken strike or catch), or due to wiring/connection faults. Diagnosing the latch problem requires observing symptoms (noise, error codes, or no click when closing the door), checking for visible damage to the latch or strike, and testing electrical continuity of the lock/switch. Replacing the faulty latch assembly or connector usually restores normal operation, but sometimes the cabinet strike or wiring harness must be replaced too.
Common Symptoms
Washer won't start or complete cycles; won't spin or drain; door-locked/error code displayed; no audible click when closing the door; intermittent operation where the latch sometimes works then fails.
Common Causes
- Failed door lock motor or internal switch (electrical failure)
- Broken or misaligned latch/strike (mechanical damage or wear)
- Damaged wiring or connector to the latch (open circuit or short)

Helpful Repair Tip
Close the door/lid and listen for a distinct 'click' from the lock area. If there's no click and the machine shows a door-locked error or won't start, remove power and test the latch assembly for continuity with a multimeter or inspect the connector and wiring for burns or loose pins.
Frequently Asked Questions
My washer shows a 'door locked' error but the latch looks fine. Is the latch still the problem?
Yes — the latch may be electrically failed even if it appears intact. Start by cycling power to the washer, check for any child lock or control lock feature, and watch for a click when closing the door. If there's no click, test the latch assembly for continuity with a multimeter or inspect the harness for damage. A control board or sensor fault can also trigger the error, but the latch is a common cause and a fairly inexpensive part to test/replace.
Can I replace the safety latch myself, and what safety steps should I follow?
Yes — many latch replacements are user-serviceable if you have basic tools. Always unplug the washer (or switch off the breaker) before starting. Remove the top or front panel per your model's service instructions to access the latch, disconnect the wiring harness, and swap the old assembly for the new one. Keep track of screws and take photos of connections if needed. If you're uncomfortable working near electrical components or the repair requires extensive disassembly, consider a professional technician.
