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

Safety first: Unplug and cool the cooker before internal inspection.

• Check for debris: Remove the inner pot and inspect the heating plate for grains, utensils, or other objects. Clean thoroughly.
• Inspect inner pot: Place the pot on a flat surface and check for rocking. Replace if significantly warped.
• Tighten hardware (advanced): Remove the bottom cover and tighten screws securing the heating plate and internal frame. Also check lid hinge screws and handle fasteners.
• Normal sounds: Some mild clicking from metal expansion is normal. Focus on unusually loud or new noises.
• Test run: After tightening and cleaning, run a short cycle with water to confirm noise reduction.

Warning: Do not overtighten screws on ceramic or thin metal parts; they can crack or strip.
