How to Fix OE Error on LG Washing Machine: Know the Causes and Remedies!
What is the reason for the OE error code appearing on my LG front-load or top-load washing machine?
The OE error code on LG front-load or top-load washing machines typically indicates a problem with draining water. The error is an abbreviation for “outlet water error,” meaning that the washer is having difficulty draining water during the wash cycle. There are several factors that can contribute to the appearance of this error code:
- Drain filter and pump housing: Over time, coins, debris, and lint can accumulate in the drain filter and pump housing, leading to clogs and hindering water drainage.

- Drain hose issues: A kinked, twisted, or blocked drain hose can impede the flow of water, triggering the OE error.
- Incorrect installation of the drain hose: If the drain hose is not installed correctly, it may not provide a proper outlet for the water, resulting in the OE error.
- Improper height of the drain hose: The end of the drain hose should not be more than 92 inches above the bottom of the washer. If it is too high, it can create a siphoning effect, causing drainage issues and triggering the OE error.
- Blockage in the air chamber or pressure sensor hose: A blockage in the air chamber or pressure sensor hose can disrupt the proper functioning of the drain system, leading to the OE error.
- Loose or disconnected harness: A loose or disconnected harness between the main board and the drain pump can result in a communication failure, causing the OE error.
- Damaged impeller of the pump: If the impeller of the drain pump is damaged or broken, it will struggle to pump out water effectively, triggering the OE error.

- Faulty drain pump: A malfunctioning drain pump can also be a culprit behind the OE error. If the pump fails to remove water from the machine adequately, it may need to be replaced to resolve the issue.
- Insufficient voltage supply to the drain pump: If the drain pump is not receiving proper voltage from the main board, it may not function optimally, resulting in the OE error.
If you encounter the OE error code on your LG washing machine, follow these troubleshooting steps to resolve the issue:
Always disconnect the power supply before performing any maintenance or repairs. Remember safety first when working with electrical appliances.
- Clean the drain filter and pump housing regularly to prevent clogs and improve water drainage.
- Ensure that the drain hose is properly aligned and free from any obstructions.
- Clear any obstructions in the air chamber or pressure sensor hose to restore normal operation.
- Make sure that the drain hose is not stretched, pinched, crushed, or kinked.
- Double-check the installation instructions to ensure the hose is positioned properly. Ideally, the end of the drain hose should be no higher than 66 inches above the bottom of the washer to maintain optimal drainage.
- Avoid creating an airtight seal between the hose and the drain to prevent water siphoning, which can affect wash/rinse performance or damage clothing.
- Check the harness connection at the drain pump and main board.
- Ensure the connections are secure.
- Inspect the impeller of the pump to ensure it is not damaged or broken.
- Measure the resistance of the pump motor using a multimeter. For a BLDC drain pump, the resistance between phase legs should be around 1.5 to 4 ohms. For a single-phase AC drain pump, the resistance between two legs should be between 10 and 20 ohms.

- Check if the drain pump is receiving the correct voltage. For a BLDC drain pump, it should receive 24 volts, while a conventional drain pump should receive 120 volts or 220 volts. (Please note that the specific voltage requirement for the drain pump of your LG washing machine may vary depending on the country or region where the washer is being used.)
- If the voltage is missing, it may indicate a faulty main board that needs replacement.
- To check the voltage, you can activate the test mode and scroll through the drain pump test or go to the spin cycle, press the start/pause button, wait for 12 seconds, and check for voltage.
- If the voltage is missing, it may indicate a faulty main board that needs replacement.
Conclusion:
Addressing the OE error code on your LG washing machine is crucial to ensuring proper water drainage during wash cycles. By following the troubleshooting steps outlined above, you can resolve the issue and restore your machine’s functionality. However, it’s important to prioritize safety throughout the process.
