Dishwasher shows d0; door-related error, may not start cycle.

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

• Check door closure: Ensure the door closes firmly and evenly. Look for obstructions around the gasket.
• Inspect latch and strike: Examine the latch mechanism and metal strike for wear or bending. Tighten any loose screws.
• Test door switch: With power disconnected, test continuity of the door switch when the latch is engaged. Replace the door lock assembly if it does not close the circuit.
• Re-test: After adjustment or replacement, restore power and start a cycle to confirm the error is cleared.
