tE3 error on some LG models, indicating heater-related temperature sensing fault.

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

Incorrect thermistor resistance, Shorted thermistor, Faulty main PCB temperature circuit, Heater stuck on

Safety first: Unplug the washer and ensure no standing water is present near electrical components.

Check thermistor resistance: Using a multimeter (if qualified), measure the thermistor at room temperature and compare to LG specs.
Inspect wiring: Look for pinched or shorted wires between thermistor and PCB.
Replace thermistor: If readings are out of range, install a new LG thermistor.
PCB diagnosis: If a new sensor does not resolve tE3, the main PCB may require replacement by a professional.
