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

Safety first: Allow the cooker to cool before inspecting internal parts.

• Check inner pot: Remove the pot and inspect the bottom for warping or dents. Replace if significantly deformed.
• Inspect heater plate: With the pot removed, gently press on the heater plate. It should be firmly mounted without excessive movement or rattling.
• Tighten mounting screws (advanced): Remove the bottom cover and locate the heater plate mounting screws. Tighten them evenly, avoiding over-tightening which can warp the plate.
• Check pot clearance: Ensure the pot does not rub against the side walls when inserted. If the outer shell is deformed, gently realign it.
• Accept minor clicks: Some mild clicking from thermal expansion is normal. Focus on loud, repetitive banging as a sign of mechanical issues.
