Dishwasher powers on but will not start when Start is pressed; sometimes beeps and the door icon flashes.

Safety first: Disconnect power before adjusting hinges or latch.

• Check for obstructions: Ensure racks are fully pushed in and no large items are protruding and preventing the door from closing fully.
• Inspect latch engagement: Close the door slowly and observe whether it aligns evenly with the cabinet. Adjust the strike plate if necessary.
• Test with gentle pressure: Hold the door firmly closed and press Start. If the cycle begins, the latch or hinges may need adjustment or replacement.

If the problem persists, replacing the door lock assembly is often required. A technician can also check for cabinet misalignment.
