How to Fix / Troubleshooting

Safety first: Do not repeatedly reset the breaker and reattempt use; this can be dangerous.

  • Inspect cord and plug: With the cooker unplugged, check for visible damage, cuts, or burn marks.
  • Dry thoroughly: If there was any spill or condensation, allow the cooker to dry for at least 48 hours in a warm, dry place.
  • Test on another circuit: If safe and permitted, try a different outlet on a different circuit to confirm the issue follows the cooker.

Persistent tripping indicates a serious electrical fault. Do not use the appliance until it has been inspected and repaired by a qualified technician.
