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

Safety first: Unplug and cool the cooker before tightening any screws.

Step-by-step checks:

• 1. Differentiate normal vs abnormal: Occasional soft clicks from the thermostat or relay are normal. Loud metallic pops or rattles are not.
• 2. Check inner pot fit: Ensure the pot sits firmly without rocking. Replace if warped.
• 3. Tighten mounting screws: Remove the bottom cover and gently tighten the screws securing the heating plate and chassis. Do not overtighten to avoid warping.
• 4. Inspect lid hinge: Tighten any loose hinge screws that may cause clunking when the lid moves.

Recommendation: If noises are accompanied by burning smells or error codes, stop using the cooker and have it inspected professionally.
