LG dishwasher Error Code tE
Thermal / thermistor error
Common Causes
- 1Thermistor failure
Step-by-Step Troubleshooting
- 1
Access the thermistor sensor — on LG dishwashers it is mounted in the tub sump area near the heating element
- 2
Disconnect the sensor and measure resistance — at room temperature (77F/25C) it should read approximately 10k ohms (NTC type)
- 3
Check the sensor wiring for corrosion or damage from exposure to moisture and detergent chemicals in the sump area
- 4
Verify the heating element is not shorted to ground — a leaking element can send false temperature signals through the chassis
- 5
If the sensor tests within spec, the main board analog input may be failed — this requires board replacement
Pro Diagnostic Tip
Hard water scale can coat the thermistor probe and insulate it from the actual water temperature, causing a delayed or inaccurate reading. If tE appears intermittently and your area has hard water (Sacramento averages 16 grains), descale the sensor probe with white vinegar before replacing it.
