Understanding the Problem
Front-load washing machines use a door latch (also called a door lock or interlock) to tell the control board the door is closed and to physically keep the door locked during a cycle. When the latching mechanism fails it can either prevent the washer from starting (control reads a door-locked error) or leave the door stuck after the cycle finishes. Failures can be electrical (solenoid/micro switch inside the lock), mechanical (broken plastic catch or strike), or caused by wiring or control issues. A failed latch often shows up as an error code, an audible click with no locking action, or inconsistent behavior — the door may lock sometimes and not others. Because the latch is a safety device, many machines will refuse to start if the lock circuit is open or unsafe. Replacing the door lock assembly or the strike is the usual fix, but checking wiring, connector pins, and the control board signals first can save unnecessary parts replacement.
Common Symptoms
Washer won't start and displays a door-locked or door error; door remains locked after cycle; intermittent locking/unlocking; clicking noise with no lock action; visible broken latch or strike.
Common Causes
- Faulty door lock assembly (internal solenoid/microswitch failed)
- Broken, bent, or misaligned door strike or plastic latch hook
- Damaged wiring, loose connector pins, or a control board output failure

Helpful Repair Tip
Listen for a click when the cycle starts and use a multimeter to check for continuity across the lock's switch during the lock phase. If you hear the actuator click but the switch shows open, replace the lock assembly; if there's no click, check wiring and the control board output first.
Frequently Asked Questions
Can I replace the washer door latch myself?
Yes — replacing a door latch is a common DIY repair on front-load machines. Unplug the washer first to avoid electric shock. Most models require opening the top or front panel and removing the door boot or trim to access the latch assembly; unplug the connector, remove the retaining screws, swap in the new assembly, reconnect, and test. Keep track of fasteners and take a photo of wiring before disconnecting. If you aren’t comfortable working near electrical components or dismantling panels, hire a technician.
How much does it cost and how long does the repair take?
Parts typically range from about $20 for a basic strike to $60–$150 for a full OEM door lock assembly, depending on brand and model. Labor (if you use a pro) can add $80–$150. A DIY replacement usually takes 20–60 minutes for someone with basic tools and a little experience; diagnosing wiring or control board issues can add time.
