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

CauseHow likelyDIY-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

  1. Unplug the washer for five minutes, then retry the cycle that failed.
  2. Test with a cold cycle: completing normally on cold supports a thermistor diagnosis and gives you a usable machine while you arrange the repair.
  3. Note which cycles trip the code — hot-only failures are practically a confirmed diagnosis for the technician.
  4. 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

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.
