The washer stops heating or displays a tE error; water may remain cold during hot cycles.

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

Failed NTC thermistor, Loose thermistor wiring, Faulty heater assembly, Control board temperature circuit fault

Safety first: Unplug the washer and allow any hot water to cool before working near the heater.

Access thermistor: On many LG front-loaders, the thermistor is mounted near the heater at the bottom front of the tub. Remove the rear or front lower panel for access.
Check connections: Ensure the thermistor connector is fully seated and the wires are not damaged.
Visual inspection: Look for signs of burning or cracking on the thermistor or heater terminals.
Replace thermistor: If the tE error persists, replace the NTC thermistor with an LG-compatible sensor. It usually pulls out from a rubber grommet.
Heater check: If the heater is open or shorted, replace the heater assembly as well.
