Possible Causes
Shorted heating element to chassis, Pinched or bare wire touching metal frame, Moisture inside base or control board, Shorted component on main control PCB
How to Fix / Troubleshooting
Safety first: Do not repeatedly reset the breaker. Unplug the cooker and keep it unplugged until the fault is found. Risk of shock or fire.
- Check for moisture: Inspect the base and control board for signs of water ingress. Dry thoroughly if moisture is present.
- Inspect wiring: Remove the bottom cover and look for pinched, melted, or bare wires touching the metal chassis. Repair or replace as needed.
- Test heater to ground: With a multimeter, check resistance between each heater terminal and the metal chassis. A low resistance indicates a ground fault; replace the heating plate assembly.
- Control board inspection: Look for burnt or cracked components on the main PCB. Replace the main control PCB if damaged.
