Multicooker beeps and displays E2; cooking does not start or stops shortly after starting.

Safety: Disconnect power and let the cooker cool fully before disassembly.

• Remove inner pot: Take out the removable cooking pot and visually inspect the metal base plate. Ensure there is no burnt food or liquid residue around the central sensor area.
• Clean sensor area: Wipe the base with a soft cloth. Do not scratch the sensor head. Dried spills can cause incorrect readings.
• Access bottom sensor: Turn the unit upside down on a soft cloth. Remove the bottom cover screws. Locate the NTC sensor clipped or screwed to the underside of the heating plate.
• Check wiring: Inspect the two‑wire harness from the sensor to the PCB for cuts, melted insulation, or loose plugs. Reseat the connector on the control board.
• Measure resistance: With the sensor disconnected, measure its resistance at room temperature. Compare to typical NTC values (often 50–150 kΩ at 25°C). If open or shorted, replace the bottom temperature sensor.
• Reassemble and test: Refit the bottom cover, plug in, and run a short program with a small amount of water in the pot. If E2 reappears and the sensor is known good, the PCB sensor circuit is likely defective and the control board should be replaced.
