Unit trips the household circuit breaker or GFCI when heating starts.

Safety first: Unplug the cooker immediately. Do not repeatedly reset the breaker without finding the cause.

Steps:

• Inspect the power cord for visible damage. Replace if any cuts or burns are present.
• Remove the bottom cover and check for signs of water ingress, especially if the cooker was recently washed or used near a sink. Dry thoroughly before further testing.
• Inspect the heating element and wiring for burn marks or contact with the metal chassis.
• If you are qualified, test the heater for continuity to ground. Any continuity indicates a ground fault and the heater plate assembly must be replaced.
• If the heater tests good, the main control board’s power device may be faulty and should be replaced.
