Washer shows E70 and may not heat or may behave erratically with temperature.

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, Broken sensor wiring, Loose connector at heater housing, Faulty PCB analog input

Safety: Unplug the washer and ensure no hot water remains.

Locate NTC: The sensor is usually mounted in the heater bracket on the tub. Disconnect its plug.
Measure resistance: Check the NTC with a multimeter. Infinite or near-zero resistance indicates failure; replace the sensor.
Inspect wiring: Repair any damaged wires between the NTC and PCB.

If a new NTC and good wiring do not clear E70, the control board is likely defective.
