Multicooker trips household circuit breaker or RCD when plugged in or when heating starts

Safety first: Do not repeatedly reset the breaker. Unplug the cooker and keep it disconnected until inspected.

• Check for moisture: If the cooker was recently washed or exposed to spills, allow it to dry for 24–48 hours in a warm, dry place.
• Inspect wiring: Remove the bottom cover and look for pinched or bare wires touching the metal chassis.
• Test heater to earth: With a multimeter, check resistance between each heater terminal and the metal body; low resistance indicates a shorted element that must be replaced.
• Inspect filter board: Look for cracked or burned capacitors on the mains filter; replace the filter board if damaged.

Warning: Earth leakage faults are serious safety issues; if you are not experienced with electrical repairs, consult a professional.
