How to Fix / Troubleshooting

Safety first: Do not work on live circuits. Turn off the breaker before opening any panels.

  • Check household supply: Verify the circuit breaker or fuse for the Sharp dishwasher circuit is not tripped. Reset if necessary.
  • Test outlet: Plug another appliance into the same outlet to confirm it has power.
  • Inspect power cord: Check the dishwasher power cord for cuts or burn marks. Replace if damaged.
  • Internal fuse: If accessible, check the internal fuse on the control board. Replace only with the same rating. If it blows again, the board or another component may be shorted and requires professional diagnosis.
