Multicooker makes loud clicking, popping, or metallic noises during heating.

Safety first: Do not touch the cooker while it is hot. Unplug before internal inspection.

• Identify noise type: Occasional soft clicks are normal relay and expansion sounds. Loud, repeated metallic bangs may indicate a warped pot.
• Check inner pot: Replace the pot if it rocks on a flat surface or if the bottom is visibly deformed.
• Reduce heat intensity: Use lower-temperature programs or reduce sauté time to minimize violent boiling.
• Internal check (advanced): Remove the bottom cover and tighten any loose screws securing the heater plate and chassis.
• If abnormal noises persist with a good pot and tight hardware, have the heater assembly and mounting inspected professionally.
