Door or hood cannot be closed or cycle will not start; E8 or door symbol appears.

Safety first: Disconnect power before adjusting mechanical parts.

• Inspect door alignment: Check that the door or hood closes evenly and that hinges are not bent. Adjust hinges or leveling feet so the door lines up with the cabinet.
• Check latch and striker: Examine the metal or plastic door hook and the striker plate on the cabinet. Tighten loose screws and replace worn or broken parts.
• Test door switch: Access the door interlock assembly behind the front panel. Manually operate the switch and listen for a clear click. Use a multimeter to verify continuity when the door is closed.
• Inspect wiring: Ensure the harness to the door switch is intact and firmly connected to the control board.
• Reset and test: After adjustments, restore power and attempt to start a cycle with the door firmly closed.
