A door that opens can be caused by a rack or utensil preventing closure, cabinet misalignment, an unlevel installation or a damaged latch. Empty the machine and run a short cycle; if the door stays shut, load items so nothing touches the door from inside.

Likely causes of “Dishwasher door pops open during the cycle”, and how to tell them apart
- 1
A rack, pan or handle presses against the door
What separates it The door pops open at the same point in the cycle, often when the wash pressure rises, and the load is tall or the rack is not pushed fully in.
How to confirm Empty the machine and run a short cycle; if the door stays shut, load items so nothing touches the door from inside.
- 2
The dishwasher is not level or fixed to the cabinet
What separates it The door hangs crooked and does not sit flush, and the machine rocks slightly when pushed.
How to confirm Check the level in both directions and confirm the mounting brackets are secure, using the installation instructions.
- 3
The door gasket is out of its groove
What separates it Water leaks at a corner and the door is harder to close on one side.
How to confirm Look around the gasket and press it back into its channel; a torn or flattened section needs replacing.
- 4
The latch or strike is worn or bent
What separates it The door will not stay shut even when empty and the latch does not click firmly.
How to confirm Close the door slowly and listen for a clear click; a soft or absent click points at the latch.
Before you touch a setting
Record this first — changing settings destroys the evidence
- The stage of the cycle at which the door opens, for example at the first fill or the main wash.
- Whether the latch clicks when the machine is empty.
- Whether anything on the racks reaches the door, including tall items on the upper rack.

0 of 4 completedObserve before changing anything
ReversibleInspect for rack, pan and handle interference and note whether the latch clicks with the machine empty.
Isolate the failing boundary
ReversibleLevel and secure the dishwasher only using installation instructions and confirm the gasket is seated.
Apply the narrow correction
ReversibleRun a short empty cycle and observe whether pressure or vibration releases the latch.
Verify the result and stop at the boundary
ReversibleStop using the unit if hot water escapes or the latch cannot remain secured.
Stop boundary
When this stops being a self-service repair
- !Stop using the unit if hot water escapes or the latch cannot stay secured, because hot water on the floor and cabinet is a safety and damage risk.

Exact questions
Common questions
Can I fix a loose latch myself?+
Only with the exact part and instructions for your model; the latch is part of the door assembly and a wrong repair can leave the door unsecured.
What can cause the door to open?+
A dish or rack blocking the door, an unlevel installation or a worn latch.
Should I check leveling?+
Yes. Adjust the feet so the dishwasher sits level and squarely in the opening.
Can a spring be worn?+
Yes. Door springs and latches can wear and may need replacement.
