LG Washer tE Error Code — What It Means and How to Fix It
The LG washer tE error code indicates a temperature sensor problem detected by the machine’s control board. On many LG washers and washer-dryer combos, tE commonly means the thermistor or temperature-sensing circuit is open, shorted, or returning a value outside the expected range. This can occur when the sensor itself fails, wiring or connectors are damaged, or the main control board is misreading the signal. When a tE error appears, the washer may pause mid-cycle, fail to heat water (in models with a heater), or stop certain cycles entirely. User impacts include longer or incomplete wash cycles, clothes not being cleaned effectively, reduced energy efficiency, and in rare cases additional stress on components if cycles continue with incorrect temperature data.
Common Causes
- Failed thermistor or temperature sensor (NTC sensor) on the tub or heater assembly
- Loose, corroded, or disconnected wiring or connector between the sensor and control board
- Damaged or pinched wiring harness due to routing or mechanical wear
- Faulty main control board (PCB) that misinterprets the sensor signal
- Malfunctioning heater element or heater assembly on washer-dryer combos that affects the circuit
- Moisture intrusion or water damage to connectors or the sensor assembly
- Intermittent contact from vibration or an unbalanced load causing false readings
Troubleshooting Steps
- Power cycle the washer: unplug the machine or switch off its breaker for 1 minute, then restore power. Sometimes transient faults clear and the error will reset.
- Run a diagnostic or test mode if your model supports it. Many LG washers offer a diagnostic cycle that can display additional error details and help confirm tE repeats consistently.
- Inspect visible wiring and connectors. Unplug the washer and check sensor wiring for burns, breaks, pinched sections, or water damage. Reseat any quick-connect plugs to ensure firm contact.
- Check for moisture or corrosion around connectors and the sensor. Dry and clean with electrical contact cleaner if needed, and allow components to fully dry before testing.
- Measure the sensor with a multimeter if you are comfortable doing so. With the washer powered off and the sensor disconnected, check continuity or resistance and compare with manufacturer specs in the service manual. If the sensor is open or out of spec it should be replaced.
- Inspect the heater assembly on washer-dryer combos. A failed heater or short in that circuit can trigger temperature faults. Only qualified technicians should disassemble heater components.
- Swap or reseat the harness between the sensor and main board if possible. Intermittent wiring faults often show up after moving harnesses during inspection.
- If wiring and sensor test normal, consider the control board. A failing PCB or damaged input circuit may misread a healthy sensor; replacing the control board may resolve persistent, unexpl
