LG Dishwasher Error Code tE — Temperature Sensor Error
What this means
The tE error code indicates the dishwasher's thermistor is not sending a proper temperature reading to the control board. Without accurate temperature data, the dishwasher cannot regulate water heating. This is typically caused by a faulty thermistor, a loose wiring connection, or a control board issue.
Step-by-step fix
4 stepsReset the dishwasher
Unplug the dishwasher for 10 minutes, then plug it back in and run a cycle. A temporary sensor glitch can cause a false tE error.
Locate and test the thermistor
The thermistor is typically located in the sump area at the bottom of the dishwasher tub. Access it by removing the lower spray arm and filter. Disconnect the sensor wiring and test with a multimeter — it should read approximately 10,000 ohms (10kΩ) at room temperature.
Check wiring connections
If the thermistor tests normally, check the wiring connector for corrosion or looseness. Trace the wire back toward the control board and look for any damage or breaks.
Moisture and heat in the dishwasher can accelerate corrosion on wire terminals over time.
Replace the thermistor
If the thermistor reads abnormally, remove it from its housing and install the replacement. Reconnect the wiring and run a test cycle.
When to call a professional
If the thermistor and wiring are fine but the tE error continues, the main control board may be at fault. Professional diagnosis is recommended.
