What the error code means

The TE error code on an LG front load washer typically indicates a problem with the thermistor or the associated heating system. The thermistor is a temperature-sensing device that monitors the temperature inside the washing machine. It is used to ensure that the water is heated to the correct temperature during the wash cycle.

Safety precautions

When working on any appliance, remember to keep safety first. Here are some tips to keep in mind: 

• Always power off and unplug your appliance or switch off the circuit breaker before attempting any maintenance or replacement work. This keeps you safe by preventing any risk of injury from electric shock.
• Wear insulated work gloves to protect your hands from sharp metal parts, pinching hazards and debris.
• Take your time and don’t rush while working to prevent accidents and personal injuries.
• Work in a well-lit area so you can clearly see and access the interior parts.
• Clear your workspace of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with bare wet hands. Make sure the work area is completely dry.
• Check your user manual to see if there are specific installation or safety instructions for your part or appliance. 
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause injury.
• Wear safety glasses when working with chemicals, dust or cleaning large debris to prevent injury. 
• If the appliance has recently been used, give it plenty of time for any heating parts to cool down before working on it. 
• Take pictures or make a note of wiring terminals or other connections before disconnecting to prevent any problems with reassembly.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.
• Turn off the water supply at the outlet before beginning repairs to any appliance parts that hold water. Have towels ready for any residual water in the system when removing parts. 

Troubleshooting steps

Test the thermistor resistance

1. Unplug the washer and access the control board.
2. Measure the resistance between the 1-2 and 1-3 connections on the control board.
3. The resistance should be between 2.5k-180k ohms.
4. If the resistance is not within this range, proceed to the next step.
5. Unplug the thermistor connector from the control board.
6. Measure the resistance of the thermistor itself.
7. The resistance should be around 11.7k ohms at room temperature.
8. If the thermistor resistance is not around 11.7k ohms, replace the thermistor.

Check wiring connections

1. Inspect the wiring between the thermistor and the control board for any damage or loose connections.
2. Check the thermistor connector and the control board connector for any signs of damage or corrosion.
3. If any issues are found, repair or replace the affected wiring or connectors.
4. If the thermistor and wiring checks out, the issue may be with the control board.
5. Use a multimeter to test the control board’s thermistor input for proper voltage and resistance.
6. Refer to the service manual for the specific testing procedures.
7. If the control board is not functioning correctly, replace the control board.
