Possible Causes

Open-circuit NTC sensor on heating plate, Shorted NTC sensor, Loose sensor connector on control board, Damaged sensor wiring harness

How to Fix / Troubleshooting

Safety first: Unplug the multicooker before opening any panels. Internal components can retain heat.

  • Power reset: Leave the unit unplugged for 5–10 minutes, then plug back in and try again. Transient faults can sometimes clear.
  • Inspect external factors: Ensure the cooker is in a dry environment and has not been exposed to liquid spills into the control panel.
  • Check internal connections (advanced): With the unit unplugged, remove the bottom cover. Locate the two-wire NTC sensor harness from the heating plate to the main PCB. Confirm the connector is fully seated and not corroded.
  • Look for damage: Inspect the sensor wires for cuts, burn marks, or pinched sections near the hinge or base. If damaged, the harness must be replaced.

If E4 persists, the NTC sensor or main control board is likely defective and should be tested and replaced using a multimeter and service documentation.
