Display shows E3 during preheat or cooking and the unit stops heating.

Safety first: Unplug the multicooker and allow it to cool fully. Do not touch the heating plate while hot.

• Clean the heating plate: Remove the inner pot. If there is burnt food, sugar, or oil on the aluminum heating plate or around the center sensor, clean thoroughly with a non-abrasive sponge and mild detergent. Dry completely.
• Check for warping or debris: Ensure no foreign objects (rice grains, beans, foil) are trapped between the inner pot and heating plate. These can cause hot spots and trigger E3.
• Inspect the underside (if accessible): With the unit unplugged, remove the bottom cover and look for melted insulation or wires touching the metal chassis near the sensor leads. Separate and re-insulate any damaged wires with high-temperature tape.
• Ventilation: Make sure the cooker is used on a hard, flat surface with adequate space around it. Blocked vents can contribute to overheating.

If E3 appears immediately on every cycle even when clean and cool, the NTC sensor is likely shorted or the control PCB is defective and should be replaced by a professional.
