Multicooker shows E3 during heating or shortly after starting a program; heating stops.

Safety first: Disconnect power and let the cooker cool fully. Do not touch the heating plate while hot.

Steps to resolve:

• Check for boil-over residue: Remove the inner pot and inspect the heating plate and center sensor area for burnt food, sugar, or thick sauces that may trap heat. Clean gently with a damp cloth and non-abrasive cleaner, then dry completely.
• Inspect for moisture: Look for condensation or liquid around the sensor boss and wiring. Moisture can cause a temporary short. Dry thoroughly and leave the unit open for at least 1 hour.
• Access the NTC wiring (advanced): Remove the bottom cover with the unit unplugged. Inspect the NTC cable for melted insulation or pinched sections where it passes through the chassis.
• Measure resistance: Use a multimeter to check the NTC resistance at room temperature. A reading near 0 Ω indicates a shorted sensor that must be replaced.
• Check PCB for damage: Examine the main control board around the NTC connector for burn marks or cracked solder joints. If present, the board may need replacement.

When to call a technician: If replacing the NTC does not clear E3, or if the PCB shows visible damage, professional repair or board replacement is recommended.
