Washer shows E12 and stops; often related to overheating or temperature sensing

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

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Open or shorted NTC sensor, Loose NTC connector, Damaged wiring between NTC and PCB, Control board analog circuit fault

Safety: Unplug the washer.

Locate NTC sensor: It is usually inserted into the heater bracket at the bottom of the tub.
Test sensor: Disconnect the NTC and measure resistance at room temperature. Compare with Fagor specifications (commonly 20–30 kΩ). Infinite or near-zero resistance indicates failure.
Inspect wiring: Check the harness from NTC to PCB for damage or loose pins.
Replace NTC: If readings are out of range, fit a new NTC sensor.

If a new sensor does not clear E12, the PCB may be misreading the signal and require replacement.
