The dishwasher door will not latch normally

With the machine off, check whether an obvious item extends beyond a rack or a rack has not returned to its normal position. Do not force the door against a dish, utensil or handle. Note whether the door moves freely until the final latch point or begins rubbing against something earlier in its travel.

On a panel-ready dishwasher, report any recent work on the furniture panel, nearby cabinetry or flooring. A decorative panel can affect the available space around an installation, but a rubbing door does not automatically mean the panel is the cause. Leave panel screws, hinges and mounting brackets untouched until the appliance and installation can be assessed.

Describe whether the controls acknowledge a start command and then wait for the door, or whether the entire display is unresponsive. Follow the exact model manual for normal operation. Never hold down or bypass a latch switch to run the dishwasher with an uncertain door closure; that removes a protection instead of solving the problem.

Useful observations before you call

• Photograph the rack position and any visible contact point while the appliance is off.
• Record whether the problem began suddenly or became gradually harder to close.
• Mention a recent installation, custom-panel adjustment or object caught in the door.
