LG TE Error Code: Heating System Problem
Updated: February 2026
The LG TE error code appears when your washing machine 's heating system isn't working properly. This error indicates the washer cannot heat water to the selected temperature, which affects wash performance, especially for cycles that require hot water for effective cleaning.
Understanding the Heating System
LG washers heat water internally using an electric heating element, similar to a water heater. A thermistor (temperature sensor) monitors water temperature, and the control board manages the heater to reach the desired temperature. The TE error triggers when the thermistor doesn't detect proper heating or reads out-of-range values.
Troubleshooting Steps
- Verify hot water is actually supplied to the washer by running a hot sink faucet
- Run a cold water cycle to see if the washer operates normally without heating
- Unplug the washer for 10 minutes to reset the control board
- Plug back in and try a warm or hot cycle again
- If TE returns, the heating element or thermistor likely needs attention
Testing Hot Water Supply
Before assuming internal heating problems, confirm hot water reaches the washer. Disconnect the hot water inlet hose and turn on the hot valve - water should flow out hot within 30 seconds. If it's cold, you have a household hot water problem, not a washer problem.
Component Diagnosis
If hot water supply is confirmed good but the TE error persists, either the heating element has burned out or the thermistor is providing incorrect readings. Testing requires a multimeter to check element resistance (typically 50-80 ohms when good) and thermistor resistance (should change with temperature).
Replacing the heating element or thermistor requires accessing the underside or rear of the washer, disconnecting electrical connections, and properly installing new components. Professional service is recommended because proper diagnosis prevents replacing the wrong part, the repair involves working with electrical components, and improper installation can cause water leaks or electrical hazards.
