Multicooker trips the household breaker or GFCI outlet when starting to heat.

Safety first: Unplug the cooker immediately. Do not repeatedly reset a breaker that trips when the cooker is used.

• Test other appliances: Confirm the circuit is otherwise healthy by plugging in a different appliance.
• Inspect for moisture: If the cooker was recently washed or a large spill occurred, allow it to dry for at least 24–48 hours in a warm, dry area before retrying.
• Check cord and plug: Look for visible damage or burn marks. If present, do not use the cooker.

If the breaker still trips as soon as the cooker begins heating, there is likely an internal short in the heater or wiring. This requires professional diagnosis and repair.
