tE1 — LG tE1 — Dryer Thermistor Fault (Not a Washer Code)

LG's official washer error-code lists (front-load and top-load) only include plain tE, for a wash-water temperature sensor fault — tE1 is not documented as a washer code. tE1, along with tE2 through tE6, is LG's dryer thermistor (heat sensor) fault, including the dryer module on WashTower and washer-dryer combo units. If tE1 is showing on your machine, it's referring to the dryer side, not the washer.

How to fix it

  1. Confirm which module is actually faulting — tE1 is LG's dryer thermistor code, not a washer code. On a WashTower or combo unit, the fault is in the dryer half.
  2. Unplug the unit.
  3. Locate the dryer thermistor near the blower/heater and test its resistance.
  4. Inspect the wiring and connector at the thermistor.
  5. Replace the thermistor if it's out of spec.
  6. If your unit is a standalone washer showing a temperature error, the applicable code is plain tE (wash-water thermistor), not tE1 — check the wash tub thermistor instead.

Why it happens

Typical signs: tE1 shown on the display of an LG WashTower or washer-dryer combo unit — dryer side · No heat or inconsistent heat during drying · Dry cycle stops early · If you have a standalone washer, this exact code isn't documented for it — double check whether the display actually reads plain tE instead

  • Faulty dryer thermistor The dryer's heat sensor has failed or drifted out of spec — the same underlying fault as tE2 on LG dryers.
  • Wiring fault at the dryer thermistor A loose or damaged connector near the dryer's blower/heater.
