LG Washer Error Code TE: Quick Summary
Error code: TE
Full form: Temperature Error
Main issue: Washer cannot heat water properly or detect correct water temperature
Common in: LG front-load washers
The TE error appears when the washer’s temperature sensor (thermistor) or heating system does not work as expected.
Symptom-Based Diagnosis
🧺 If your washer shows TE and stops mid-cycle
Likely cause:
Heating element not warming water
Thermistor not sensing temperature change
💧 If washer fills with water but does not heat
Likely cause:
Faulty heater
Loose wiring to heating element
⚡ If TE appears after a power cut
Likely cause:
Control board glitch
Temperature reading interruption
Component-by-Component Causes
🔥 Heating Element Issue
The heater warms water during wash cycles.
If it burns out or fails, the washer throws a TE error.
🌡️ Thermistor Failure
The thermistor measures water temperature.
A defective thermistor sends wrong data to the control board.
🔌 Wiring or Connector Problem
Loose, corroded, or damaged wires between the heater, thermistor, and control board can trigger the TE error.
🧠 Control Board Malfunction
In rare cases, the main control board fails to process temperature signals correctly.
Step-by-Step Fix Checklist
✅ Step 1: Power Reset
Unplug washer
Wait 15 minutes
Plug back in and restart
This fixes temporary electronic glitches.
✅ Step 2: Try a Cold Wash Cycle
Select a cold-water cycle
Start the washer
If it runs normally, the issue is almost certainly heating-related.
✅ Step 3: Check Power Supply
Ensure stable voltage
Avoid extension cords
Low voltage can affect heater performance.
✅ Step 4: Inspect Heating Circuit (Advanced)
If you have technical experience:
Check heater resistance with a multimeter
Inspect thermistor and wiring
If not, stop here and call a technician.
What NOT to Do
❌ Do not ignore the TE error
❌ Do not keep restarting repeatedly
❌ Do not run hot cycles forcefully
This can damage the heater and control board.
When Professional Repair Is Required
Call service if:
TE error appears every wash
Cold cycles work but hot cycles fail
Reset does not clear the error
You smell burning or hear clicking sounds
Contact authorized LG service for safe repair and genuine parts.
Prevention Tips
Avoid frequent hot-water cycles
Use recommended detergent
Ensure proper electrical grounding
Do not overload the washer
The LG washer error code TE is a temperature-related safety error. While resets and cold cycles may help temporarily, recurring TE errors usually indicate a faulty heating element or thermistor. Early repair prevents higher costs later.
