What Does Error tE Mean?
The tE error on your LG Dishwasher indicates a malfunction with the temperature sensor, also known as the thermistor. This error can cause the appliance to display incorrect water temperatures or fail to heat water altogether. If you're experiencing the tE error, your dishwasher may stop mid-cycle or show abnormal temperature readings. It's essential to address this issue promptly to ensure proper functioning.
Common Symptoms:
