What does the LG tE error code mean?
tE (Thermistor Error) means the temperature sensor is not giving readings within expected parameters. Either the sensor itself is faulty, the wiring connection is loose, or (less commonly) the heating element is causing an out-of-range temperature reading.
How to fix the LG tE error code
- Run a cold wash — if it completes without error, the fault is confirmed as thermistor-related.
- Unplug and access the heating element assembly (inside the drum at the rear, accessed from the front after removing the door seal on most LG models).
- The NTC thermistor is a small two-wire probe attached to the element. Check its connector is seated firmly.
- Test with a multimeter — approximately 10,000–20,000 ohms at room temperature is normal.
- Replacements cost £8–15 and the repair is straightforward.
