Loud popping, clicking, or metallic banging noises from inside the multicooker during heating.

Safety first: Unplug and allow to cool before inspecting the base.

• Check inner pot: Place the pot on a flat surface and press on the bottom. If it rocks or flexes, it may be warped and should be replaced.
• Inspect heating plate: Remove the inner pot and gently press the central heating plate. A small amount of movement is normal, but rattling or clunking suggests loose screws underneath.
• Tighten mounting hardware: Remove the bottom cover and tighten the screws securing the heating plate and inner pot detection mechanism. Do not overtighten to avoid warping.
• Test with water: Reassemble and run a short cycle with water to confirm noise reduction.

Some clicking from metal expansion is normal, but persistent loud banging after tightening may indicate a defective heating plate assembly.
