LG Styler Code tE4: Steam Thermistor

Medium · inspection needed

Code: tE4
Appliance: Styler
Brand: LG
Warranty: 30-day workmanship

What tE4 means

tE4 on an LG Styler steam closet is a Steam Thermistor Error, a temperature sensor message about the steam system. The closet uses that reading to control steam production, so with tE4 showing, steam cycles may not run or may end early. Unlike tE1 and tE3, which concern the ducts, this one belongs to the steam side. It appears on models such as the S3WFBN, and repair service is the next step.

Common causes of tE4

The steam thermistor reading
The wiring and plug for that sensor
The steam sensor's input on the control board
Scale or residue in the steam system

✓ One safe check you can try

1. Check that the dispenser holds only clean water. 2. Make sure the drain tray is in place and has not been refilled into the dispenser. 3. Skip steam cycles until the closet has been checked. 4. Call us to book a visit, since tE4 needs repair service.

! Why to stop there

We read the steam thermistor directly, since the display alone cannot show whether the sensor, wire or board is behind it.
If scale is present, we check the steam heater at the same time because it can affect the readings.
The price is written before we start, and the repair has a 30-day workmanship warranty.

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

tE4tE4 questions

What does tE4 mean on an LG Styler?

Steam Thermistor Error is the listed name. The temperature sensor in the steam system is not reading normally, so the closet cannot control steam production and may end the cycle.

Can I use the Styler without steam?

Stopping all cycles until it is checked is safer. tE4 can interrupt a cycle, and repeated tries will not change the reading, so a visit is the quickest way to find the cause.

Could dirty water cause tE4?

Only clean water belongs in the dispenser, and other liquids can harm the steam system. We check for buildup and for the water you have been using when we test the sensor.
