What tE means

tE on an LG dishwasher means there is an issue with the temperature sensor. That can be a contact problem or a sensor that has failed. The sensor tells the control how warm the water is so it can heat to the right level and protect the dishes and the machine. Without a reliable reading, the cycle stops and tE shows. Codes can differ by model. Because the sensor sits inside the machine, it needs a technician rather than a home adjustment.

Common causes of tE

  • Temperature sensor
  • Poor contact at the sensor connector
  • Control input that reads the sensor
✓ One safe check you can try

1. Cancel the cycle and let the water drain. 2. Open the door and let the tub cool. 3. Do not open panels or touch wiring. 4. Wash dishes by hand until the repair. 5. Call us and mention the code tE.

! Why to stop there
  • A loose contact and a failed sensor give the same code, so we test the connection before we replace the sensor.
  • We check the reading against the actual water temperature.
  • We run a full cycle and confirm normal heating before we finish.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

tEtE questions
Is tE the same as HE?

No. HE is about the heater. tE is about the temperature sensor. They can show up together, but the code tells us which part to test first.

Can a loose connection cause tE?

Yes, a contact problem is one of the reasons. We test the connector before we replace a sensor, so you do not pay for a part you may not need.

Can I keep using the dishwasher?

We would not. Without a temperature reading the control cannot heat the water correctly. Wait for the repair. Wait for the repair, and wash dishes by hand until we have tested the sensor and its connection.
