Machine stops mid-cycle and displays E5; door or hood appears closed but cycle will not continue.

Safety first: Disconnect power before adjusting or replacing any switches. Avoid bypassing safety interlocks.

Inspection and adjustment:

• Check door or hood alignment: Ensure the Champion dishwasher door or hood closes fully and evenly. Adjust hinges or hood springs if the door does not seat properly against the frame.
• Inspect door latch and actuator: Examine the latch hook and the actuator tab that engages the interlock switch. Look for bent metal, wear, or broken plastic. Straighten minor bends; replace damaged latch components.
• Test door interlock switch: Locate the door/hood safety switch. With power off, disconnect the wires and test continuity with a multimeter while operating the switch manually. Replace the switch if it does not change state reliably.
• Check wiring harness: Follow the harness from the switch to the control board. Look for pinched, broken, or burned wires, especially near hinge points. Repair or replace damaged wiring.
• Reset and test: After adjustments, restore power and run a test cycle. Confirm that E5 does not reappear when the door is closed firmly.

When to call a technician: If the control board does not recognize a good switch signal or if multiple safety circuits are involved, professional diagnosis is recommended.
