Unusual loud clicking, buzzing, or humming noises from the base during operation.

Safety first: Unplug and allow the cooker to cool before inspection.

• Check pot and surface: Ensure the cooker is on a stable, level surface and the inner pot is seated correctly.
• Inspect for foreign objects: Remove the inner pot and look for utensils, rice grains, or other objects on the heating plate. Remove any debris.
• Tighten mounting screws: From the bottom, tighten the screws that secure the heating plate to the chassis.
• Relay noise: Some clicking from the relay is normal, but very loud or rapid clicking may indicate a failing relay on the PCB, which should be replaced by a technician.
