Multicooker displays E3 and stops heating, often during high-temperature modes like Fry or Sauté.

Safety first: Unplug the cooker and allow it to cool for at least 30 minutes before further inspection.

• Check cooking conditions: Ensure you are not running high-heat modes with an empty pot or with very little oil/food. Always follow Xiaomi’s minimum content guidelines.
• Inspect inner pot: Remove the pot and check for warping, dents, or carbon buildup on the bottom. A deformed pot can cause hot spots and poor contact with the heater plate.
• Clean heater plate: Wipe the heater plate and central sensor area with a soft, dry cloth. Remove any burnt food or residue that could insulate the sensor.
• Check for blocked ventilation: Ensure the cooker is used on a hard, flat surface with adequate space around it. Do not block side or bottom vents.
• Reset and test: After cooling, plug the unit back in and test with a low-temperature program (e.g., Rice or Porridge). If E3 appears immediately, there may be a sensor or control fault.
• Internal inspection (advanced): With the unit unplugged, remove the bottom cover. Inspect the thermal cutoff and NTC sensor on the heater plate for discoloration or damage. Check wiring for signs of overheating.
• Replace damaged parts: If the thermal cutoff is open or the NTC sensor reads out of range, replace the faulty component with an original Xiaomi-compatible part.
• Seek service: If E3 persists after verifying pot, cleaning, and sensor condition, the main control board may be misreading temperature and should be checked by a technician.
