Washer-dryer combo shows tE1 during drying; drying function stops or does not heat.

Safety first: Unplug the unit and allow it to cool completely before servicing the dryer section.

• 1. Clean lint paths:
  • Remove the lint filter and clean thoroughly.
  • Inspect the internal lint duct (if accessible) for heavy buildup and clean carefully.
• 2. Access dryer thermistor:
  • Remove the top cover and, if necessary, the rear panel.
  • Locate the dryer exhaust duct inside the unit; the thermistor is usually mounted on or near this duct.
• 3. Inspect and test thermistor:
  • Check the connector and wiring for damage.
  • Use a multimeter to measure resistance and compare to LG specs.
  • Replace the LG dryer thermistor if readings are out of range or open/shorted.
• 4. Check airflow:
  • Ensure the combo's venting (if vented model) is not blocked or crushed.
  • For ventless models, ensure condenser and internal ducts are clean.
• 5. Professional help: If tE1 persists after thermistor replacement and cleaning, the main PCB dryer circuit may be defective and should be serviced by a technician.
