Possible Causes
Tripped circuit breaker or blown fuse, Faulty power cord or terminal block, Defective main control board, Loose wiring at the junction box under the dishwasher
How to Fix / Troubleshooting
Safety first: Before touching any wiring, ensure the circuit breaker is off.
- 1. Check household power: Verify that the kitchen circuit breaker is not tripped. Reset if necessary.
- 2. Inspect junction box: Remove the toe-kick and open the electrical junction box where the house wiring connects to the dishwasher. Confirm that wire nuts are tight and no wires are burned.
- 3. Test outlet/line: If the dishwasher uses a plug, test the outlet with another appliance. If hard-wired, use a multimeter (if qualified) to confirm the voltage at the junction box.
- 4. Control board: If power is present at the dishwasher but the control panel is dead, the main control board or user interface may be faulty and typically requires replacement.
If you are not experienced with electrical work, contact a licensed electrician or appliance technician.
