Multicooker shows E14 and aborts cooking, often accompanied by a strong smell of overheating plastic or electronics.

Safety first: Immediately unplug the cooker if you smell burning. Do not continue using it until inspected.

• Check placement: Ensure the cooker is used on a hard, heat-resistant surface with at least several centimeters of clearance on all sides. Do not place it in enclosed cabinets while operating.
• Inspect vents: Look for dust buildup or obstructions in side and bottom vents. Clean gently with a soft brush or vacuum.
• Fan check (if present): Some Xiaomi models have a small internal fan. Listen for fan operation during cooking. If the fan is silent or noisy, it may be failing.
• Open housing (advanced): With the unit unplugged, remove the cover to inspect the PCB. Look for darkened areas, burnt components, or melted plastic near power resistors or regulators.
• Replace failing fan: If the fan is seized or noisy, replace it with a compatible 12 V or 24 V fan as specified for your model.
• PCB replacement: If components on the board are visibly burnt or E14 recurs after cleaning and fan replacement, replace the main control PCB.
• Do not bypass sensors: Never bypass thermal sensors or fuses to stop E14; this can lead to fire hazards.
