LG Washer tE/tE1/tE2 Error Code: What It Means & What to Check

Q: My LG washer is showing tE, tE1, or tE2. What does it mean, and what should I check?

A: On many LG washers, tE / tE1 / tE2 indicates a water temperature sensing problem. In plain terms, the washer’s control isn’t getting a normal signal from the thermistor (temperature sensor) in the tub/heating circuit. Start with the safe checks below. If the code returns, we’ll see how Beacon can help.

What usually causes tE/tE1/tE2?

Most commonly, this error is caused by:

A loose, wet, or oxidized thermistor connector
A failed thermistor
Wiring damage between the sensor and the main control

Less often, inconsistent fill temperature can contribute—for example, selecting very hot water while the hot valve is partially closed or flow is restricted.

Fast, safe steps to try at home

Power reset: Turn the washer off, then switch the breaker OFF for 5 minutes (or unplug for 5 minutes). Restore power and try again.
Test with a normal temperature: Run a Normal cycle using Warm (avoid the hottest and coldest extremes during testing).
Confirm water supply: Make sure both wall valves are fully open and hoses aren’t kinked.
Cool-down if it was just run hot: If you recently ran a high-temp cycle (like Sanitary/Allergen), let the washer sit for about 30 minutes and retry.

Can detergent, oversuds, or the load trigger tE?

Sometimes. Heavy oversuds can trap heat and disrupt normal sensing, especially if the washer struggles to drain or rinse cleanly.

Use HE detergent only
For many loads, start with about ½ cap (adjust based on soil level and water hardness)
Avoid stacking extra additives that increase foaming

If you see foam in the door boot (front-load) or excessive suds during agitation, reduce detergent on the next cycle.

When should you stop DIY and call Beacon?

Schedule service if tE/tE1/tE2 returns after the reset and a Warm/Normal test, or if the washer will not finish a cycle.

Our friendly technicians in yellow will:

Check thermistor readings (resistance vs. temperature) and confirm the sensor is responding correctly
Inspect the harness and connectors for corrosion, loose pins, pinched wiring, or water intrusion
Verify fill valve operation and confirm the control is interpreting inputs correctly

We’ll replace only what testing confirms is actually faulty.

Why choose Beacon for LG washer repairs?

LG-savvy diagnostics for sensors, valves, wiring, and controls
Clear guidance when repair vs. replacement doesn’t make sense
Local, tidy service from our friendly technicians in yellow

Frequently Asked Questions

What do LG washer tE/tE1/tE2 errors mean?

They indicate a temperature sensing problem. The thermistor (temperature sensor) or its wiring is not providing a normal reading to the control.

What should I try first before calling for service?

Do a 5-minute power reset, confirm both hot and cold valves are fully open, then run a Normal cycle with Warm water. If the code returns during the test, stop and schedule service.

Can oversuds cause a tE temperature error?

Yes, sometimes. Excess suds can trap heat and interfere with normal sensing. Use HE detergent only and reduce the dose if you notice foam or poor rinsing.

Could my water supply cause the washer to throw tE/tE1/tE2?

It can contribute. If a valve is partially closed or flow is restricted, the washer may see unexpected temperatures during fill and flag a sensing issue.

What will a technician test for this error code?

A technician will compare thermistor readings to temperature, inspect connectors and wiring for damage or corrosion, verify valve operation, and confirm the control is processing inputs correctly. Parts are replaced only as needed.
