Dishwasher powers on but will not start a cycle; Start button beeps or flashes and nothing happens.

Safety first: Turn off power before adjusting the latch or removing the door panel.

• Check door alignment: Ensure the dishwasher is level and not twisted in the cabinet. Adjust leveling legs so the door closes evenly on both sides.
• Inspect latch and strike: Look for wear or bending on the latch hook and tub strike. Adjust or replace as needed.
• Test door switch: With the inner door panel removed, test the door switch for continuity when the latch is engaged. Replace the door lock assembly if it fails.
• Control reset: After mechanical fixes, restore power and attempt to start a cycle. Some models require holding Start for several seconds to begin.
