LG Washer Error Code tE — Water Temperature Sensor Error
What this means
The tE error code indicates the LG washer's thermistor (water temperature sensor) is sending an abnormal reading to the control board. The washer cannot properly regulate water temperature for the selected cycle. This is usually caused by a faulty thermistor, a loose wiring connection, or in rare cases a control board failure.
Step-by-step fix
4 stepsReset the washer
Unplug the washer for 10 minutes and plug it back in. Run a cycle to see if the error clears. A temporary sensor glitch can cause a false tE code.
Locate the thermistor
The thermistor is typically located in the rear of the tub, near the heating element (on front-load models). Remove the rear access panel to reach it. It is a small sensor with two wires attached.
On top-load LG washers, the thermistor may be attached to the water inlet area instead.
Test the thermistor with a multimeter
Disconnect the thermistor's wire connector. Set your multimeter to resistance (ohms) and test across the two terminals. At room temperature (approximately 77°F / 25°C), a properly functioning thermistor should read approximately 10,000 ohms (10kΩ). A reading of 0 (shorted) or infinity (open) means it is faulty.
The resistance will decrease as temperature increases — this is normal NTC thermistor behavior.
Replace the thermistor if necessary
Remove the single screw or clip holding the thermistor in place. Pull the sensor out of its housing. Install the new thermistor, reconnect the wiring, and run a test cycle.
When to call a professional
If the thermistor tests normal but the tE error persists, the issue may be with the wiring harness or the main control board. A technician can diagnose control board faults with specialized equipment.
