Dishwasher displays E10 and will not start the wash cycle; door appears closed but machine thinks it is open.

Safety first: Disconnect power before removing any door panels.

• Check door closure: Ensure the dishwasher is properly leveled and not twisted in the cabinet. Close the door firmly and listen for a positive latch click.
• Inspect latch strike: Examine the metal strike on the tub frame for bending or misalignment. Adjust slightly so the latch engages fully when the door closes.
• Access door lock: Remove the outer door panel to expose the door lock assembly. Inspect for cracks, broken plastic, or loose mounting screws.
• Test door switch: With a multimeter, test continuity of the door switch when the latch is engaged. If the switch does not close electrically, replace the door lock assembly.
• Check harness: Inspect the wiring harness running through the door for pinched or broken wires, especially near the hinge area. Repair as needed.

Do not bypass the door safety switch; always replace faulty components with genuine Fulgor Milano parts.
