You load up the dishwasher, add detergent, press start, and expect the door to latch closed automatically. But instead of hearing the anticipated click, the dishwasher door remains slightly ajar, leaving your dishes exposed instead of cleaning. It’s incredibly frustrating when a dishwasher door won’t latch properly.
The automatic door latching function is essential to keep the door tightly closed throughout wash cycles. When it fails, the dishwasher can’t operate correctly. In this article, we’ll cover how to diagnose and repair latching problems with your dishwasher door.
Common Reasons Why a Dishwasher Door Won’t Latch
Here are the most common culprits behind a door that won’t close and latch fully:

Broken or Loose Latch Assembly
The latch assembly includes the latch, catch, and various moving parts. If any become cracked or detached, the door can’t latch securely.
Obstructed or Stretched Latch Spring
The latch spring provides tension to retract the latch into the catch/strike. Obstructions and stretching can prevent the spring from pulling the latch into place.
Worn Rubber Door Seal
The tub rubber seal creates a tight closure between the tub edge and door. If it becomes warped or torn, the door seal will be compromised.
Alignment Issues
If the door hangs unevenly, the latch won’t align correctly with the strike. Bent or loose hinges could cause misalignment.
Faulty Door Switch and Wiring
The magnetic door switch communicates when the door is closed. If it malfunctions, the dishwasher won’t start wash cycles.
Clogged Latch Assembly
Food debris and hard water buildup can obstruct the latch parts from moving smoothly to engage the strike/catch.
Control Board Failure
Electrical issues with the control board can prevent the catch from releasing to let the latch close the door.
Troubleshooting Dishwasher Door Latching Problems
Follow these tips to troubleshoot a door that won’t latch closed:
1. Check for Obstructions
Look for large debris, food particles, utensils blocking the door. Remove anything obstructing closure.
2. Inspect Seal and Alignment
Check that the seal is intact with no holes or tears. Make sure the unit is level and door hangs straight.
3. Clean the Door Edges
Wipe away any food, grease, or grime buildup where the door seals meet the tub.
4. Test Door Strike and Latch
Manually engage the strike with the latch. Replace any damaged or worn parts.
5. Adjust Hinges
If door is misaligned, loosen hinge screws and readjust to straighten the door.
6. Check Door Switch and Wiring
Inspect switch and connections for damage. Use multimeter to check for continuity.
If the latch still won’t click into place securely, contact a technician to examine the latch mechanisms and dishwasher wiring further.
