LG washing machines are designed for convenience and efficiency, providing precise control over water temperature and washing cycles. However, sometimes the appliance can display the tE error code, leaving users unsure about what went wrong. This guide will explain what tE means, why it happens, and how you can troubleshoot or fix it yourself.
Understanding the tE Error
The tE error code in LG washers stands for Temperature Error. Essentially, the machine is signaling a problem in the heating circuit — it is unable to heat water to the required temperature.
Typical signs of this error include:
- Washing stops mid-cycle and the tE error appears on the display.
- The washer drum is spinning, but water remains cold even when a hot water cycle is selected.
- On models without a display, all temperature indicators may light up or flash simultaneously.
Programs that do not require heated water may still run normally, so you can continue washing clothes using a cold water cycle while troubleshooting the issue.
Causes of the tE Error
Several factors can trigger this error in LG washing machines:
- Faulty heating element: The heating coil may have burned out or developed an internal break.
- Wiring or connection issues: Loose or disconnected wires between the heater and control board can prevent proper heating.
- Control board glitches: The electronic controller may malfunction temporarily, showing a false tE error.
- Temperature sensor failure: If the sensor cannot read the water temperature correctly, the washer may stop to avoid damage.
Understanding these causes helps you determine whether a simple DIY fix is possible or if professional repair is required.
How to Fix tE Yourself
Some tE errors are minor and can be resolved without calling a technician. Here’s a practical guide for simple troubleshooting:
Step-by-Step DIY Check:
- Power Reset: Disconnect the washing machine from the outlet for 10–20 minutes. This can reset the electronic control board if the error was caused by a temporary glitch.
- Check Wiring: Inspect the wiring between the heating element and the control board. Look for loose connectors, damaged wires, or corrosion. Secure or replace connections as needed.
- Test the Heating Element: If comfortable using a multimeter, measure the resistance of the heating coil to ensure it is within specifications. A broken or burnt-out element must be replaced.
- Try a Cold Wash: If immediate washing is needed, select a cold water cycle while investigating the error.
If these steps do not resolve the tE error, the problem is likely a faulty heating element or a malfunctioning control board, which usually requires professional repair.
Preventive Measures
To reduce the risk of temperature errors in your LG washer:
- Avoid frequent interruption of cycles by unplugging the machine unnecessarily.
- Periodically inspect the heater and wiring during maintenance checks.
- Use detergent and cleaning products appropriate for your washer to avoid residue buildup that can affect sensors.
- Run occasional maintenance cycles with hot water to keep the heating element in good condition.
Quick Troubleshooting Checklist
- Disconnect the washer for 10–20 minutes to reset the controller.
- Inspect wiring between heater and control board for loose or damaged connections.
- Test or replace the heating element if necessary.
- Use cold water cycles if immediate washing is required.
- Contact a professional if the tE error persists after DIY checks.
Addressing the tE error promptly ensures your LG washing machine continues to operate efficiently, providing reliable cleaning performance while avoiding further damage to the appliance.
