Unusual loud clicking, popping, or metallic noises from the base during heating.

Safety first: Turn off and unplug the cooker if noises are very loud or accompanied by burning smell.

Steps:

• Inspect contact surfaces: Remove the pot and check for grains, utensils, or debris on the heating plate. Clean thoroughly.
• Check pot bottom: Place the pot on a flat surface to see if it rocks. Replace if warped.
• Light clicking: Occasional soft clicks from relays or metal expansion can be normal. Continuous loud metallic sounds are not.

If noise persists with a clean, flat pot, internal components may be loose and should be inspected by a technician.
