Multicooker shows E2 and stops heating or will not start any cooking program.

Safety first: Unplug the unit and let it cool fully. Do not touch the heater plate if it is hot.

• Check for overheating signs: Remove the inner bowl and inspect the heater plate and surrounding plastic. Look for discoloration, melting, or burnt smell which indicates severe overheating.
• Dry the sensor area: If liquid has boiled over, gently dry the heater plate and center sensor area with a soft cloth. Allow at least 1 hour of air drying before retrying.
• Power reset: After cooling and drying, plug the unit back in and test a low-temperature program. If E2 appears immediately, the sensor or wiring is likely shorted.
• Internal check (advanced): Remove the bottom cover to inspect the NTC sensor wiring. Look for pinched or melted wires touching the metal chassis. Separate and insulate any damaged wires with high-temperature electrical tape as a temporary measure.
• Permanent repair: Replace the bottom NTC temperature sensor and any damaged wiring harness. If the heater plate is also damaged, replace the complete heater plate assembly.
