Dishwasher door is hard to close or pops open slightly during operation.

Safety first: Ensure the dishwasher is empty before adjusting its position.

Step-by-step checks:

• Check for obstructions: Make sure racks are fully pushed in and no large items are protruding.
• Inspect gasket: Look for folds or bulges in the door gasket that could prevent full closure.
• Level and square: Adjust leveling legs so the tub is square in the opening and the door aligns evenly with the cabinet front.
• Strike adjustment: Slightly loosen the door strike screws and adjust its position so the latch engages smoothly, then retighten.

Warning: Do not force the door closed; this can damage the latch and hinges.
