LG Washer tE — What It Means & How to Fix It
Also shown as tE1, tE2 on some models.
The washer's temperature sensing is returning impossible readings, so heated cycles stop — worth one reset, after which the thermistor is the likely repair.
What this code means
tE (with tE1/tE2 variants narrowing the sensor location on some models) is LG's heating error, and the thermistor — the sensor reporting water temperature — is the usual cause. The board refuses to run the heater on faulty data, so warm and hot cycles halt while cold ones often still work.
tE concerns the washer's internal heater circuit. If your machine is a washer-dryer combo, the dryer side has separate temperature codes — check which mode threw the error.
Most likely causes
| Cause | How likely | DIY-fixable? |
|---|---|---|
| Failed or drifting thermistor | Common | No — technician job |
| Corroded sensor connector | Occasional | No — technician job |
| One-off glitch after a power event | Occasional | Yes — power reset |
| Heater element failure affecting the sensing circuit | Less common | No — technician job |
What you can try yourself
- Unplug the washer for five minutes, then retry the cycle that failed.
- Test with a cold cycle: completing normally on cold supports a thermistor diagnosis and gives you a usable machine while you arrange the repair.
- Note which cycles trip the code — hot-only failures are practically a confirmed diagnosis for the technician.
- Stop there. The thermistor sits with the heating assembly inside the cabinet, in the territory this site always hands to a professional.
When to call a technician
- tE returns on every heated cycle after a reset.
- Warm cycles run cold (or scalding) even when the code doesn't appear — a drifting sensor on its way out.
- The code arrives with burning smells or a tripped breaker: unplug and don't retry.
Typical professional repair cost: Thermistor replacement typically runs $100–$200 with labor; pairing it with a heater element pushes toward $250–$350.
Frequently asked questions
Can I keep using cold washes with a tE error?
Often yes, and it's a reasonable bridge until the repair — the fault usually only blocks cycles that need the heater. Just don't treat it as permanent: some models eventually refuse all cycles once the sensor reads fully open or shorted.
What's the difference between tE1 and tE2?
They distinguish which thermistor circuit complained on models with more than one sensing point. From the owner's side the response is identical; the variant mainly saves the technician diagnostic time.
Why do thermistors fail?
Heat cycling and scale. The sensor lives against the heating element through thousands of temperature swings, and its resistance curve drifts until the board sees values it can't trust. It's a wear part with a long but finite life.

- LG Washer OE Your LG washer couldn't pump the water out within its time limit — start with the drain pump filter behind the lower front panel, which fixes most OE errors.
- LG Washer IE Water isn't reaching the drum fast enough — usually a tap, hose, or inlet-screen issue you can sort out in a few minutes rather than a failed component.
- LG Washer UE The drum's load is too unbalanced to spin safely — small uE means the washer is fixing it by itself, capital UE means it gave up and needs your help.
- LG Washer LE The motor couldn't turn properly — often a one-off from an overloaded drum that clears after a rest, but a repeating LE usually means the motor's hall sensor has failed.
