If you own an LG washer, you expect it to make laundry day easier, not more stressful. But seeing an unexpected “tE” code pop up on your machine can be confusing and frustrating. What does it mean? Is your washer broken? How can you fix it without calling a technician? This guide explains everything you need to know about the LG washer code tE, why it happens, and how to deal with it. You’ll learn simple steps, common mistakes, and practical advice so you can get your washer running again quickly.
What Does Lg Washer Code Te Mean?
The tE code on an LG washer stands for “thermistor error.” The thermistor is a temperature sensor inside your washing machine. It tells the control board how hot or cold the water is. When the thermistor does not send a correct signal, your LG washer cannot continue the wash cycle safely, so it shows the tE code and stops.
Most LG washers display this error as tE, tE1, tE2, or tE3. Each version points to a problem with the washer’s ability to sense water temperature. If the thermistor fails, the washer might use water that is too hot or too cold, possibly damaging clothes or the machine.
How The Thermistor Works In Your Lg Washer
The thermistor is a small but important electronic part. It changes resistance depending on the water temperature. The washer’s control board reads this change and adjusts the heating element or water mix to reach the right temperature for the wash cycle.
A working thermistor means:
- Accurate water temperature for each program
- Safe operation during hot cycles
- Energy efficiency by heating water only when needed
If the thermistor is faulty or disconnected, the washer cannot “know” the water temperature. This is why the tE error is so important to fix quickly.
Common Causes Of The Lg Washer Te Code
Several factors can trigger the tE error code. Knowing the most common causes helps you troubleshoot faster and avoid wasting time or money.
- Faulty Thermistor: The most frequent reason. Thermistors can fail with age, water damage, or electrical problems.
- Loose or Damaged Wiring: Wires connecting the thermistor to the control board can become loose, corroded, or broken.
- Control Board Issues: Rarely, the washer’s main control board develops a fault and cannot read signals correctly.
- Water Heating Element Malfunction: If the heating element is faulty, it can affect the thermistor readings.
- Moisture or Soap Build-Up: Sometimes water leaks or leftover detergent build up around the sensor, causing false readings.
How To Fix Lg Washer Code Te: Step-by-step
Most tE errors can be fixed at home with simple tools and patience. Here is a practical, step-by-step guide.
1. Reset Your Washer
Sometimes, the tE code appears due to a temporary glitch. Try these steps first:
- Turn off your washer and unplug it from the power outlet.
- Wait 5-10 minutes to let the electronics reset.
- Plug the washer back in and power it on.
- Run a short cycle to check if the error is gone.
If the tE code returns, continue troubleshooting.
2. Check The Thermistor And Its Wiring
The thermistor is usually located near the bottom of the tub or attached to the heater assembly. You’ll need a screwdriver and a multimeter (for testing).
- Unplug the washer for safety.
- Find the thermistor location in your model’s manual or look for a small round sensor with wires near the heating element.
- Inspect the wires for damage, corrosion, or loose connections. Reconnect any loose wires.
- If you have a multimeter, disconnect the thermistor and measure its resistance. Most LG thermistors should show 10 kΩ (10,000 ohms) at room temperature.
If the reading is much higher or lower, the thermistor is likely faulty and needs replacement.
3. Examine The Heating Element
A faulty heater can also confuse the thermistor. Check for:
- Visible signs of burning, cracks, or mineral buildup
- Blown fuses or tripped circuit breakers
- Use a multimeter to check for continuity in the heating element
If you find damage, replace the faulty part.
4. Clean Moisture Or Soap Build-up
Remove the thermistor and clean the area with a dry cloth. Remove any soap residue, lint, or moisture. This step is often missed by beginners but can solve the problem if the sensor was just dirty.
5. Replace The Thermistor If Needed
If all else fails and the thermistor shows the wrong resistance, buy a replacement that matches your LG washer model. Install it carefully, reconnect all wires, and test the washer.
When To Call A Professional
While many tE errors are easy to fix, sometimes the problem goes deeper. Call a service technician if:
- You see signs of water leaks inside the washer body.
- The control board shows burn marks or smells burnt.
- You replaced the thermistor, but the tE code still shows.
- You are not comfortable opening the washer or handling electronics.
Attempting repairs beyond your skill can damage your washer or void the warranty.

How To Prevent The Lg Washer Te Error In The Future
Prevention is always better than repair. Here’s how to reduce your chances of seeing the tE code again:
- Regularly clean your washer: Run a tub clean cycle monthly to remove soap residue.
- Use the right detergent: Too much soap can cause buildup and sensor errors.
- Check for leaks: Fix small leaks before they reach the sensor.
- Avoid overloading: Too much laundry can stress the heater and thermistor.
- Inspect wiring yearly: Look for loose or corroded wires, especially if your washer is in a humid area.
A non-obvious tip: Always check your home’s power supply. Power surges can damage sensitive parts like the thermistor. Using a surge protector for your washer adds extra safety.

Lg Washer Models Most Likely To Show The Te Code
Not all LG washers have the same risk of a tE error. Older models (made before 2015) and some high-efficiency models show this error more often. Models with steam or extra-hot cycles also use the thermistor more, increasing wear.
Some examples:
- LG WM2101HW
- LG WM3470HVA
- LG WM3997HWA
- LG WT4801CW
If your washer is over 7 years old, consider replacing the thermistor as part of regular maintenance.
Signs The Thermistor Is Failing (before Te Code Appears)
One insight many owners miss: your washer often gives warning signs before the tE code appears.
Watch for:
- Wash cycles that take much longer than normal
- Clothes coming out too hot or cold
- Error codes that appear briefly and disappear
- Water that does not heat up in hot cycles
If you notice these, it’s wise to check the thermistor before the washer stops working.
How To Find The Right Replacement Parts
Not all thermistors and heating elements are the same. To avoid wasting money, always check:
- The washer’s model number (found on the back or inside the door)
- The part number (in your user manual or LG’s website)
- If buying online, use only trusted sources. Avoid very cheap parts, as they often fail quickly.
For official LG parts, you can use the LG Support page to search by model.
What If The Te Code Appears Mid-cycle?
A tE error sometimes happens in the middle of a wash, not at the start. This often means the thermistor is failing only when it gets hot. If you can run cold cycles but not hot or steam, the thermistor is likely the problem.
Testing with different cycles can help narrow down the issue.
