If your LG washing machine is showing a TE error code, you’re likely dealing with a water heating issue—but don’t worry. While this can sound technical, understanding what’s happening can help you take the right steps before calling a technician. In many cases, the problem involves a faulty heating element or sensor, which a professional can easily fix.

This guide explains the LG washer TE error, common causes, troubleshooting steps, and when to seek help.

What does the TE error code mean?

The TE code on an LG washer stands for Thermistor Error or Temperature Error. Your washer uses a thermistor (temperature sensor) to regulate water heat. If it detects abnormal readings—or no readings at all—it stops the cycle and displays the TE error to prevent further issues.

The error typically means there’s a disruption in the heating system, which includes the thermistor, heating element, or related wiring.

Common causes of the TE error

Here are the most frequent reasons your LG washer isn’t heating water properly and shows a TE error:

• Faulty heating element
  The element may be burned out and unable to warm the water during the cycle.

• Defective thermistor
  If the thermistor gives inaccurate readings or fails entirely, the washer can’t regulate temperature.

• Wiring or loose connections
  Damaged or disconnected wires between the heater and control board can trigger the LG washer TE error.

• Control board malfunction
  Less commonly, the main board may misinterpret signals and stop the cycle prematurely.

• Continuity fault in circuit
  Lack of electrical continuity in the heating components can prevent water from heating properly.

What you can do about it

If you’re seeing a TE code on your LG washer, try these steps:

1. Restart the Washer

Unplug your washer from the power outlet. Wait 3–5 minutes, then plug it back in. Sometimes, this clears a temporary glitch.

2. Check Your Wash Settings

Make sure you haven’t accidentally selected a cold-only cycle. Some temperature-sensing errors happen when low-temp water is misinterpreted.

3. Don’t Overload the Machine

An overloaded drum can cause the washer to overheat or strain internal sensors. Try running a smaller load.

4. Contact a Technician if the Error Returns

If the TE error comes back or never clears, it’s time to call a certified appliance technician to inspect the following:

• Thermistor – test for accurate resistance readings
• Heating element – check for continuity and physical damage
• Wiring harness – inspect for burns or loose connections
• Control board – diagnose for electronic faults

Only trained professionals can safely access and test these internal parts.

When to call a professional

You should schedule repair service if:

• The TE error shows immediately after starting a cycle
• The washer doesn’t heat water in hot or warm settings
• You notice burnt smells or buzzing near the bottom of the washer
• The error persists after unplugging and restarting
• Other codes or symptoms (e.g., cycle stops or cold washes only) appear

Diagnosing a washing machine thermistor fault or water heater error in an LG washer requires tools and expertise that only a certified tech can provide.

Conclusion

The TE error code in LG washers signals a heating system problem—most often involving the thermistor or heating element. While simple steps like resetting the washer or checking settings can sometimes help, most causes need professional repair.

Acting quickly helps prevent cycle interruptions, protect your laundry, and keep your LG washer running efficiently.
