Multicooker beeps and shows E2; it will not heat or start cooking.

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

• Power reset: Disconnect the appliance from the mains for 5–10 minutes, then plug it back in and try a simple program. Sometimes, transient faults clear after a reset.
• Check inner pot seating: Remove the inner pot and wipe its underside dry. Clean the central heating plate and the small temperature sensor button in the middle with a soft, dry cloth. Reinstall the pot, ensuring it sits flat and rotates freely.
• Inspect for damage: Examine the central sensor button or disc on the base. If it is loose, cracked, or pushed in, the NTC sensor assembly may be damaged and require replacement.
• Advanced wiring check: With the unit unplugged and the bottom cover removed, locate the two-wire NTC sensor harness from the center of the heater plate to the control PCB. Check for burnt, cut, or disconnected wires. Reseat the connector on the PCB.
• Next steps: If E2 persists, the NTC sensor or the control PCB is likely faulty. Replace the bottom temperature sensor (NTC probe) first, as it is typically less expensive, then the control board if needed.
