Dishwasher shows E06 and will not start or complete a cycle; door may appear closed.

Safety first: Disconnect power before working on the door assembly.

Steps:

• Check door closure: Ensure the door closes firmly and evenly. Look for obstructions around the door seal or racks preventing full closure.
• Inspect latch: Open the door and examine the metal or plastic latch on the tub and the catch on the door. If bent or loose, adjust or tighten mounting screws.
• Test operation: Gently press on the door while starting a cycle. If the machine starts only when pressed, the latch or switch is likely worn.
• Replace latch assembly: Remove the inner door panel screws, carefully separate the panel, and locate the door lock/switch module. Disconnect wiring, remove the old latch, and install the new one in reverse order.

When to call a technician: If the error persists after latch replacement or if wiring in the door harness is damaged, professional service is recommended.
