This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

Possible Causes

Shorted NTC sensor, Moisture bridging sensor terminals, Damaged sensor harness insulation

Safety first: Unplug the cooker and allow it to cool fully.

Dry interior: If there was a boil-over, ensure no liquid has entered the base. Let the unit dry for several hours.
Inspect sensor wiring: Access the bottom and check the sensor harness for melted insulation or pinched wires causing a short.
Clean connectors: Disconnect and reconnect the sensor plug to clear minor corrosion.

If F3 persists, replace the NTC sensor and inspect the control board for damage.
