E2 error appears shortly after starting a program; unit may heat briefly then shut off with beeping.

Safety: Unplug the multicooker and let it cool fully before inspection.

• Dry the sensor area: Remove the inner pot and carefully wipe the central heating plate and sensor area with a dry cloth. If there has been a spill or boil-over, moisture may be causing a short.
• Open the base: Place the cooker upside down on a towel and remove the bottom cover. Locate the NTC sensor on the heating plate and its wiring.
• Inspect for moisture and corrosion: Look for signs of liquid ingress, corrosion on the sensor terminals, or green/white deposits on the connector. Dry gently with a hair dryer on low heat at a safe distance, or leave open to air-dry for several hours.
• Check resistance: With a multimeter, measure the sensor resistance at room temperature. If it reads near 0 Ω (short) or extremely low compared to specifications, the sensor is defective and must be replaced.
• Reconnect and secure wiring: Ensure the sensor wires are not pinched or rubbing against sharp metal edges. Reconnect firmly to the main PCB.

If E2 remains after replacing the sensor, the control board's sensor input circuit is likely damaged and the main PCB should be replaced by a technician.
