Dishwasher powers on but will not start a cycle; start button does nothing and no error code is shown.

Safety first: Disconnect power before adjusting switches or panels.

Enabling cycle start:

• Verify door closure: Ensure the Champion door or hood is fully closed and latched. Listen for the click of the interlock switch.
• Check door switch: Test the door interlock switch for continuity when closed. Replace if it does not change state.
• Reset the machine: Turn the power off for 30 seconds, then back on. Some models require pressing a reset or cancel button before starting a new cycle.
• Test start button: If using a membrane keypad, test for response of other buttons. If only the start button fails, the keypad may need replacement.

When to call a technician: If all safety switches test good and the control still will not start a cycle, the control board may be faulty.
