Multicooker displays E2 and will not heat or start a program.

Safety first: Unplug the cooker and allow it to cool completely before any inspection.

• Power reset: Unplug the unit for 5–10 minutes to clear any transient error, then plug it back in and try a simple mode like Sauté with an empty, dry pot.
• Check for moisture: Remove the inner pot and inspect the heating plate area. If you observe moisture, spills, or condensation around the center sensor area, gently dry with a soft cloth and allow the unit to air-dry for several hours before retrying.
• Inspect underside vents: Look through the bottom vents for signs of liquid intrusion or corrosion near the sensor wiring. If heavy corrosion is observed, do not use the cooker until it has been inspected by a technician.
• Avoid using with a warped pot: A severely warped inner pot can stress the sensor and heater. If the pot bottom is not flat, replace the pot before further use.

If E2 reappears consistently, the bottom NTC sensor or its harness is likely defective and should be replaced. This requires opening the base and should be performed by a qualified service provider.
