Dishwasher will not power on at all; no lights or display, completely dead.

Safety First: Turn off the breaker before opening any electrical compartments.

• Verify power at outlet/circuit: Confirm the breaker is ON and not tripped. Test the outlet or circuit with another appliance if accessible.
• Inspect junction box: Remove the toe-kick and open the dishwasher’s junction box. Tighten any loose wire nuts and look for burnt wires. Repair or replace damaged wiring.
• Check door latch: If the unit has interior lights or a faint click but no response, the door latch switch may not be closing. Inspect and adjust or replace the latch assembly.
• Control board diagnosis: If power is present at the control board but there is no display or response, the main control board is likely failed and should be replaced.
• When to call a technician: If you are not comfortable working with 120 VAC wiring, contact a professional.
