Understanding the Problem
Front-load and some top-load washers use a door latch/lock mechanism (mechanical strike or electromechanical interlock) to keep the door closed while a cycle runs. When the latch or lock fails the washer may refuse to start, stop mid-cycle, or leave the door locked after a cycle ends. Problems can be electrical (failed lock motor, burned contacts, or bad wiring) or mechanical (broken plastic latch, worn strike, or misaligned door). Diagnosing the root cause requires checking both the mechanical strike/catch and the lock assembly (for front-load machines, the door lock / interlock). A failed latch assembly can show obvious physical damage, but many electrical lock failures only show as error codes or by using a multimeter to test continuity. Replacing the defective part is usually straightforward and the most reliable fix—especially if you confirm the lock does not show continuity when activated or the strike is visibly cracked or misaligned.
Common Symptoms
Washer refuses to start and displays a door/dl error, door stays locked after cycle, door will not latch or closes but does not engage, intermittent starts or stops during cycle.
Common Causes
- Broken or cracked plastic latch or strike (mechanical failure)
- Failed electromechanical door lock / interlock (worn contacts, motor/solenoid failure)
- Faulty wiring or connector (corrosion, pinched wires) or control board not sending lock signal

Helpful Repair Tip
With power disconnected, try to close the door and manually operate the latch to see if it catches; then unplug and use a multimeter to check the lock assembly for continuity when the washer is asked to lock (or check for the proper voltage at the connector while a cycle tries to start).
Frequently Asked Questions
Can I use a temporary fix if the washer door won't lock?
Temporary fixes are limited. If the latch is simply misaligned you may be able to realign the strike or door hinge to allow proper engagement. For electrical lock failures, bypassing the lock is unsafe and can cause water spills or injury; do not bypass on machines that will spin with the door open. Best practice is to replace the damaged latch/lock assembly.
Is replacing the door lock/latch something I can do myself and how much will it cost?
Yes—many homeowners can replace a latch or lock assembly with basic tools in 20–60 minutes. Costs vary by model: mechanical strikes are usually inexpensive ($10–30), electromechanical door locks typically range $40–120. If the control board or wiring is the problem, costs will be higher. Always unplug the washer and follow the service manual or a reliable step-by-step guide for your model.
