The door swings shut but won’t click, or it latches and then pops back open before the cycle starts. Before assuming the latch mechanism itself has failed, rule out the far more common culprit: something in the way.
Part of the dishwasher troubleshooting guide. If the door latches fine but the dishwasher still won’t start, see dishwasher not starting.

Repair or Replace?
Every part on this list is under $50, and most fixes are free. A door won’t-latch issue is one of the cheapest dishwasher repairs there is, rarely a reason to think about replacement unless the whole door panel is warped.
Latch and strike plate designs differ across Whirlpool, GE, Samsung, LG, Bosch, KitchenAid, Frigidaire, and Maytag, some use a simple hook latch, others a spring-loaded catch. Brand-specific part guides are coming.
Frequently Asked Questions
The door latches but pops open a few seconds later, what does that mean?
That usually points to worn latch spring tension or a strike plate that's no longer catching fully, rather than an obstruction, since obstructions prevent the initial latch entirely.
Can overloading the racks really prevent the door from closing?
Yes, a tall pot or utensil in the top rack pushing against the door is the single most common cause on this page, check that first every time.
Is it safe to keep using the dishwasher if the latch feels loose?
Run it cautiously for now, but don't ignore it. A door that can pop open mid-cycle risks water leaking onto the floor and, rarely, minor injury from a swinging door.
Should I replace the whole latch assembly or just the strike plate?
Check which part shows visible wear first. Many models sell the hook, spring, and strike plate as separate low-cost parts rather than one assembly.
