Multicooker makes loud clicking, popping, or buzzing noises during operation beyond normal relay clicks.

Safety first: Unplug the cooker before inspecting internal components. Do not touch internal parts while powered.

• Check pot seating: Ensure the inner pot is fully seated and making flat contact with the heater plate. A warped pot can cause popping sounds.
• Inspect bottom surface: Make sure the cooker is on a stable, level surface. Uneven surfaces can amplify vibration.
• Internal inspection (advanced): Remove the bottom cover and check for loose screws, brackets, or components that may rattle. Tighten as needed.
• Look for arcing: In a darkened room (unit unplugged first, then briefly powered for observation if safe), look for small sparks at connections. If seen, unplug immediately and seek professional repair.
