LG Washer Error Code tE

The tE code on an LG washer indicates a temperature sensor error related to the washing heater inside the tub. It can be caused by a disconnected or incorrectly seated sensor connector, a faulty temperature sensor, or a condition where the machine detects frozen water while the sensor reads an abnormally high temperature between 100 and 105 degrees Celsius. The washer shuts down automatically to protect itself from potential damage.

No, you should not continue running the washer while the tE code is active. The machine has shut down because it cannot reliably monitor the temperature of the washing heater, which is a safety-critical function. Running a cycle without a functioning temperature sensor creates a risk of overheating. Resolve the fault before resuming normal use.

If only the connector needs to be reseated or cleaned, the repair can cost nothing beyond your time. If the temperature sensor itself has failed, replacement parts typically range from around 15 to 50 dollars depending on the model, with professional labor adding anywhere from 80 to 200 dollars or more depending on your location and the technician. Diagnosing the fault yourself before calling a technician can help keep costs lower.

Start by unplugging the washer and locating the temperature sensor connector for the washing heater. Check that the connector is fully seated and free of corrosion or damaged pins, then reseat it firmly. If the connection looks good, test the sensor itself with a multimeter for proper resistance. If the sensor has failed, it will need to be replaced to clear the error.

A reset may temporarily clear the display, but the tE code will return if the underlying fault has not been corrected. The error is triggered by an actual hardware condition, either a connection problem or a sensor failure, so resetting the machine without addressing the root cause will not produce a lasting fix. Diagnose and repair the sensor or connector first.
