The TE error on your LG washer means the machine has detected a problem with the water heating system, usually caused by a faulty thermistor (water temperature sensor) or heating element. To fix this, you need to troubleshoot these components by safely testing and replacing the defective part. Following step-by-step instructions will help you restore proper water heating and clear the TE error.
What does the TE error mean on my LG washer?
The TE error code stands for "Thermistor Error." It appears when the washer detects an issue with the water temperature sensor circuit, which monitors the water temperature during a wash cycle. Your LG washer relies on the thermistor to measure water temperature and ensure it heats correctly. If water isn’t heating properly or sensor readings are outside expected ranges, the washer triggers the TE error to protect the machine and maintain wash quality. This error usually points to a problem with the thermistor, heating element, or the wiring connecting them.
Why is my LG washer’s water not heating?
Several common causes lead to the TE error and prevent water from heating. The thermistor may be faulty or damaged, causing incorrect temperature readings. The heating element could be burned out or broken, so it can’t warm the water. Wiring issues like loose, corroded, or damaged connections between the control board, thermistor, and heating element can interrupt the heating circuit. Less commonly, the control board itself may malfunction and fail to regulate heating properly. In most cases, the problem lies with the thermistor or heating element.
How can I safely troubleshoot the TE error and water heating issue?
Before you start, unplug the washer to avoid electrical shock. Locate and remove the back or bottom panel with a screwdriver to access the thermistor and heating element. Use a multimeter set to measure resistance (ohms) to test each component:
- Disconnect the thermistor wires and measure resistance across its terminals. At room temperature, it should show a specific resistance range. An open circuit (infinite resistance) or a short (zero resistance) means the thermistor is faulty.
- Disconnect the heating element wires and measure resistance across its terminals. A working element usually shows low but not zero resistance. Infinite or very high resistance indicates a broken heating element.
- Inspect all wiring and connectors for signs of damage, corrosion, or looseness.
Identifying which component is defective based on these tests will guide your repair.
How do I replace a faulty heating element or thermistor?
- Remove the access panel to reach the faulty part.
- For the heating element, disconnect its wires, unscrew or unclip it from the tub or heater housing, then carefully pull it out.
- For the thermistor, disconnect its wiring plug and remove it from its mounting point, usually clipped or screwed onto the tub.
- Install the exact replacement part specified for your LG washer by reversing the removal steps.
- Reconnect all wires securely and reattach the access panel.
You’ll need a screwdriver set, a multimeter for testing, and possibly pliers. Handle parts gently to avoid damage. Double-check all connections before closing the washer to avoid further issues.
How to verify if the repair fixed the TE error and water heating problem
Plug the washer back in and run a wash cycle that heats water, such as a cotton or heavy-duty cycle set to warm or hot. Watch the display for the TE error code. If it doesn’t appear and the water feels warm during or after the cycle, the repair was successful. If the error repeats or water stays cold, recheck your installation and wiring. Sometimes the control board may need to reset—unplug the washer for a few minutes before trying again.
What can I do to prevent the TE error from happening again?
Regular maintenance helps prevent the TE error. Clean the washer’s drum and detergent dispenser to avoid buildup that can affect sensors. Don’t overload the washer, since extra strain can damage components like the heating element. Use appropriate water temperature settings within your washer’s recommended range. Address unusual noises or error codes promptly. Avoid repairs beyond your skill level to prevent damage or voiding your warranty.
Before you start
This guide applies to LG washers displaying the TE error related to water heating issues. You do not need special privileges, but you must unplug the washer before opening panels or working on electrical components. No system restart is required, but always perform safety checks such as confirming the washer is unplugged and you have the right tools on hand before proceeding.
Conclusion
After replacing the faulty thermistor or heating element and confirming the TE error is cleared, your LG washer should heat water properly and run normal cycles. If the issue persists despite your efforts, consider contacting a professional technician for further diagnosis and repair. Careful repairs and regular maintenance will help extend your washer’s lifespan and keep it working well.
Frequently Asked Questions
Will fixing the TE error myself void my LG washer warranty?
If your washer is still under warranty, opening it and replacing parts yourself can void the warranty. Check your warranty terms or contact LG support before attempting any repairs.
When should I call a professional instead of fixing the TE error myself?
Call a professional if you’re uncomfortable working with electrical parts, lack the proper tools, or suspect the control board is the problem. Also, if your repair attempts don’t fix the error, professional help can provide accurate diagnostics and safe repair.
How much do replacement heating elements and thermistors usually cost?
Prices vary by LG washer model and parts supplier. Heating elements and thermistors are moderately priced components, but costs can differ widely. Check authorized parts dealers for exact prices.
