Troubleshoot error code “TE” in LG dishwasher

Error: “TE”
Description: Drying system error
Cause: Issue with the thermistor or water temperature too high
Solution: Disconnect and reconnect the appliance, check the thermistor, adjust water temperature

When your LG dishwasher displays an error code “TE,” it can be a moment of concern. But don’t panic; we’ll explain what this error means and how you can resolve it.

What Does the “TE” Error Code Mean?

The “TE” error code on LG dishwashers refers to a problem with the appliance’s drying system. This error can be caused by a failure in the thermistor, which is a temperature sensor, or because the water entering the dishwasher is too hot.

Steps to Solve the “TE” Error

Disconnect and Reconnect the Dishwasher

  1. Unplug the dishwasher: Before taking any action, make sure to disconnect the dishwasher from the power source.
  2. Wait for 60 seconds: Once unplugged, wait at least a minute before plugging it back in. This can help reset the system and clear the “TE” error code.
  3. Reconnect the dishwasher: After waiting, plug the dishwasher back in and check if the “TE” error code has disappeared.

Check the Thermistor

If the problem persists after restarting the dishwasher, the thermistor may be defective or experiencing issues. The thermistor is a component that measures the water temperature, and if it’s not functioning correctly, it can cause the dishwasher to display the “TE” error code.

  • Access the thermistor: You may need to consult your LG dishwasher manual to locate and access the thermistor.
  • Visual inspection: Check for signs of damage or wear on the thermistor.
  • Continuity test: Using a multimeter, verify the continuity of the thermistor. If it doesn’t show continuity, it may need to be replaced.

Adjust the Water Temperature

If the thermistor appears to be working correctly, the issue could be the water temperature entering the dishwasher. If it’s too high, it can trigger the “TE” error code.

  • Check the water heater temperature: Ensure that the temperature of your home’s water heater is not set above 120°F (49°C), which is the recommended temperature for most appliances.
  • Adjust the temperature: If necessary, lower the water heater temperature, and check if this resolves the issue.

Request Repair If after following these steps, the “TE” error code continues to appear, it may be necessary to seek the assistance of a professional technician. A technician can diagnose and repair any underlying issues that may be causing the error.

The “TE” error code on your LG dishwasher doesn’t have to be the end of the world. By following these steps, you can attempt to resolve the issue on your own. Remember that if you’re not comfortable performing any of these actions or if the problem persists, it’s always advisable to contact a professional for safe and effective repair.
