Understanding the Problem
Brief explanation: The door latch (door lock assembly) secures the dishwasher door and tells the control board the door is closed. When it fails the dishwasher will refuse to start, stop mid‑cycle, show door error codes, or the door may remain loose or physically broken. Below are step‑by‑step diagnostics and repair steps you can follow to confirm and replace the latch. 1) Tools & prep - Tools: #2 Phillips, nut driver set (5/16" or 1/4" depending on screws), small flat screwdriver, needle‑nose pliers, multimeter (for continuity), towel to protect door. Optional: trim panel removal tool. - Safety first: Disconnect power to the dishwasher at the breaker or unplug it. Confirm power is off with a non‑contact tester. Lay a towel under the door to protect flooring and catch small parts. 2) Quick diagnostics (1–5 minutes) - Visual: Open the door and inspect the latch area for obvious cracks, broken plastic, or a loose metal strike. Check the actuator (the part that the latch catches on the cabinet) for damage. - Mechanical test: Close the door slowly and listen for the latch to engage. If it feels loose, sticky, or doesn’t click, the latch is suspect. - Electrical test: Remove the inner door panel (steps below) and backprobe the latch connector. With the latch removed from power, use a multimeter set to continuity/ohms and operate the latch manually (press plunger or actuate solenoid) — you should see continuity change when the latch is engaged/disengaged. No change = failed switch/lock. 3) Remove inner door panel to access latch - Support the door: Fully open the dishwasher door and support it on a towel. Remove the screws around the inner door panel perimeter (usually Phillips screws behind the top trim and along the edge). Keep screws organized—some are different lengths. - Separate panels: Carefully lift the inner panel away a few inches to access the wiring harness to the latch. Don’t fully detach until you disconnect the harness. 4) Disconnect & remove the old latch - Unplug the wiring harness to the latch (press the release tab and pull). Note connector orientation or take a photo. - Remove the latch mounting screws/clips (commonly 2 screws) holding the latch assembly to the inner door. Pull latch out from the front. If your model has a separate strike on the cabinet, inspect and remove/replace it if damaged. 5) Install new latch - Insert the replacement latch assembly into the opening, secure with the mounting screws, and reconnect the wiring harness. Confirm the connector snaps fully. - Reassemble the inner door panel: align the inner and outer door skins, reinstall all screws in their original positions. 6) Test before full reassembly - Restore power at the breaker briefly and try to start a short cycle to confirm the door latches and the unit will run. If it starts and no door error codes appear, power off and fully tighten screws. - Final check: Run a rinse or short wash to ensure latch stays engaged throughout the cycle and no water leaks from door edges. 7) Additional notes - If the latch is physically OK but the door still won’t latch, check the strike/strike bracket on the cabinet and the door hinges alignment. - If the multimeter shows continuity but the control still reports a door error, the wiring harness or control board input may be faulty. Test continuity back to the control or consult a technician. Safety note: Always disconnect electrical power before working on appliances. The edges of the door inner panel are sharp—wear gloves or use a towel. If you’re unsure about electrical tests, stop and call a professional.
Common Symptoms
Dishwasher won’t start or pauses mid‑cycle, door won’t lock or feels loose, audible clicking when trying to start but cycle won’t begin, door lock error codes on display, broken or cracked plastic latch/strike.
Common Causes
- Broken or worn door latch assembly (mechanical failure of plunger or housing)
- Failed latch microswitch or solenoid — no electrical signal to the control
- Misaligned door strike, broken strike bracket, or door hinge/spring issue causing poor engagement

Helpful Repair Tip
To confirm the latch is faulty without full disassembly: press the door closed with steady pressure while trying to start a cycle. If the dishwasher still won’t start or reports a door error, the latch switch is likely not signaling the control. For definitive proof, remove the inner door trim and test the latch's microswitch for continuity as you manually activate the latch.
Frequently Asked Questions
How do I know if the door latch or the strike/hinge is the problem?
Start with a visual and mechanical check: if the latch housing is cracked or the plunger doesn’t move smoothly, replace the latch. If the latch looks OK but the door doesn’t engage or sits off‑center, inspect the strike on the cabinet and the door hinges/springs for alignment or broken parts. You can also test electrically: remove the inner door panel and check the latch microswitch with a multimeter — no state change when actuated means the latch assembly is bad.
Can I tape the door shut and run the dishwasher if the latch is broken?
No — not recommended. The dishwasher’s control typically requires a confirmed door‑closed signal to run; bypassing the latch can be unsafe, may allow water to spray out, and could prevent the cycle from running or energize components when the door is open. If you must temporarily run a short test, only do it with the door partially supported and a professional assessment planned immediately afterward.
