What tE means
LG identifies tE as a heating error, commonly associated with the washer thermistor or its circuit.
What you may notice
- The cycle stops
- Water temperature may be incorrect
- The display shows tE
- The code returns after a restart
Most likely causes
- 01A thermistor fault
- 02A loose sensor connection
- 03A heating-circuit problem
- 04Damaged wiring
- 05A control fault
Safe checks, in order
Start with the simplest non-invasive check. Stop as soon as the error clears; repeated resets can hide a condition without correcting it.
Stop the cycle
Let the water and drum cool.
Disconnect power
Unplug the washer for about 10 seconds as LG directs.
Restart once
Restore power and try a short empty cycle.
Record the timing
Note whether tE appears during fill, wash, or a heated cycle.
Know where to stop
Do not open panels or test the heater or sensor circuit. Internal line voltage requires trained service.
When to call a technician or support
Schedule service if tE returns after the single reset or water becomes abnormally hot.
When you call, have the exact product or vehicle model, model year where relevant, the complete code or symbol, and when it appeared.
