LG Dishwasher tE / TE Error Code

tE is a service-oriented temperature sensing condition. The official guidance says the error requires technician inspection if it persists.

Applies to LG dishwasher

What the appliance detected

Detected condition

LG identifies tE as a thermal or temperature-sensor error.

What may contribute

Possible causes

  • A temperature sensor contact or sensor issue may be involved.
  • LG documentation also describes tE as occurring when water temperature is above a documented threshold or when there is a thermistor problem.
  • An internal sensor, wiring, or control condition may require service.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the code and model

    • Photograph or write down tE or TE before clearing the display.
    • Confirm the full model number and owner manual for service context.

  2. Stop for temperature or electrical hazards

    • Stop use for burning odor, smoke, steam that seems abnormal, sparking, unusual heat, visible damage, or water near electrical parts.
    • Let hot surfaces and water cool before touching any accessible racks or dishes.

  3. Request service if the code remains

    • Because LG says tE requires technician inspection, do not pursue internal checks.
    • Preserve the code and request service if it persists or returns.

Actions not recommended

  • Do not remove panels, access sensors, test wiring, or replace a thermistor based on tE alone.
  • Do not test live voltage or operate the dishwasher while overheating or electrical symptoms are present.
  • Do not treat tE as a user-clearable maintenance reminder.

When to stop and request service

  • Request service if tE persists or returns.
  • Request service immediately for abnormal heat, steam, smoke, burning odor, sparking, or visible damage.
  • Stop whenever troubleshooting would require internal sensor, wiring, or control access.
