LG Washing Machine Error Code tE — How to Fix (Thermistor / water heating sensor error)

If you’re seeing the LG Washing Machine error code tE on your appliance’s display panel, it can be frustrating and confusing. This error code indicates a problem with the thermistor or water heating sensor, which is crucial for regulating water temperature during wash cycles. In this comprehensive guide, we’ll walk you through what the tE error code means, how to diagnose the issue, and steps to fix it.

What LG Washing Machine Error tE Actually Means

The tE error code on your LG Washing Machine signifies a thermistor or water heating sensor error. The thermistor is a temperature-sensing device that monitors the water temperature in the washing machine. When the thermistor or water heating sensor detects an abnormal water temperature reading, it triggers the tE error code. This error can cause the washing machine to malfunction, leading to issues like failure to heat water, abnormal wash cycle times, or a complete halt of the wash cycle.

The thermistor or water heating sensor is usually located near the heating element or inside the tub of the washing machine. Its primary function is to ensure that the water temperature is within a safe and optimal range for washing clothes. If the thermistor or sensor fails or provides incorrect readings, the washing machine’s control board will display the tE error code.

Diagnose This in 5 Minutes (Before Calling Anyone)

Before calling a professional or spending money on repairs, perform these quick diagnostic checks:

• Power Cycle: Unplug the washing machine from the power outlet, wait for 5-10 minutes, and then plug it back in. This simple reset can sometimes resolve the issue.
• Check the Thermistor or Water Heating Sensor: Locate the thermistor or water heating sensor and verify that it’s properly connected and not damaged.
• Inspect the Water Inlet: Ensure that the water inlet is not clogged and that the water supply is turned on.
• Check for Blockages: Verify that there are no blockages in the drain hose or pump filter.

• Wear protective gloves and safety glasses.

Step-by-Step Instructions:

1. Locate the thermistor or water heating sensor, usually found near the heating element or inside the tub.
2. Disconnect the electrical connector from the thermistor or sensor.
3. Use a multimeter to test the resistance of the thermistor or sensor. Compare the readings to the manufacturer’s specifications.
4. Remove the screws holding the thermistor or sensor in place.
5. Gently pull out the thermistor or sensor from its mounting bracket.
6. Install the new thermistor or sensor, ensuring it’s properly seated and secured.
7. Reconnect the electrical connector to the thermistor or sensor.

What “fixed” looks like vs “still broken”:

• If the tE error code disappears after replacing the thermistor or sensor, the repair is successful.
• If the error code persists, you may need to investigate other causes, such as loose connections or a faulty control board.
