Multicooker displays E2 and refuses to start or aborts cooking shortly after heating begins.

Safety first: Unplug the cooker and let it cool completely. Do not attempt to operate with an active E2 error.

Inspection and correction:

• Remove the inner pot and check for any liquid spills or food residue around the center sensor area on the heater plate. Wipe thoroughly with a dry cloth and allow to air dry.
• Turn the unit over and remove the bottom cover screws to access the wiring.
• Locate the bottom NTC sensor harness and inspect for signs of moisture, corrosion, or melted insulation. Dry any moisture with a lint-free cloth.
• If you have a multimeter and are qualified, measure the resistance of the NTC sensor at room temperature. A reading near 0 Ω indicates a shorted sensor and it must be replaced.
• Inspect the harness for crushed or pinched sections where the two conductors may be touching. Repair or replace the harness if damaged.
• If the sensor measures within normal range but E2 persists, the main control board’s sensor input circuit may be faulty and require replacement.

Note: Do not bypass or short the sensor to clear the error; this is unsafe and can cause overheating.
