Owning an LG washing machine can make laundry chores a breeze, but encountering error codes can be frustrating. One such error is the E1 error, which may leave you wondering what went wrong with your appliance. In this comprehensive guide, we’ll unravel the mystery behind the E1 error in LG washing machines. We’ll explain what the error code signifies, explore the potential causes behind it, and most importantly, provide you with detailed solutions to resolve the issue. So, let’s dive in and get your LG washing machine back to its optimal performance.

Understanding the E1 Error Code

The E1 error code is a common error found in LG washing machines, and it typically indicates a problem with the water supply. When this error occurs, you may see it displayed on the control panel, along with an accompanying beep or alarm. The E1 error can disrupt your laundry routine, but understanding its underlying causes will help you tackle it effectively.

Possible Causes of the E1 Error

  1. Water Supply Issues: The primary reason for the E1 error is related to water supply problems. This could be due to a clogged or kinked water inlet hose, a closed water supply valve, or low water pressure in your area.
  2. Faulty Water Inlet Valve: A malfunctioning water inlet valve can also trigger the E1 error. The valve is responsible for letting water into the machine, and any issue with it can disrupt the water flow.
  3. Blocked Filters: Over time, filters in the water inlet valve and hoses can become clogged with debris and sediment, hindering the water flow and leading to the E1 error.
  4. Drainage Problems: Though it may seem unrelated, poor drainage can indirectly contribute to the E1 error. If the washing machine doesn’t drain effectively, it can impact the water supply process and trigger the error.

How to Resolve the E1 Error

Now that we have identified the potential causes of the E1 error, let’s explore the step-by-step solutions to troubleshoot and resolve the issue with your LG washing machine.

Solution 1: Check Water Supply

The first step is to inspect the water supply to your LG washing machine. Ensure that the water inlet hose is not bent or kinked, as this can restrict water flow. Next, verify that the water supply valve is fully open, allowing water to flow freely into the machine. If the valve is partially or fully closed, open it to its maximum capacity. Low water pressure can also trigger the E1 error, so make sure the water pressure in your area is adequate for the washing machine to function correctly.

Solution 2: Inspect the Water Inlet Valve

The water inlet valve is a critical component responsible for allowing water into the washing machine. If it’s faulty or clogged, it can trigger the E1 error. To inspect the valve, first, disconnect the power supply and turn off the water supply valve. Locate the water inlet valve at the back of the washing machine and remove the inlet hoses. Check for any blockages or debris in the valve. If you notice any issues, consider cleaning or replacing the valve as necessary.

Solution 3: Clean the Filters

Clogged filters can impede the water flow, leading to the E1 error. To clean the filters, turn off the water supply and disconnect the inlet hoses. Look for filters inside the water inlet valve and the hose connections. Gently remove the filters and rinse them under running water to remove any dirt or debris. Once cleaned, reassemble the filters and hoses, and ensure they are securely attached.

Solution 4: Check Drainage

As mentioned earlier, poor drainage can indirectly contribute to the E1 error. Ensure that the drain hose is correctly installed and not blocked or obstructed. If the drain hose is too deep into the drain pipe, it can create a siphoning effect and disrupt the water supply. Adjust the drain hose if needed, and ensure it is placed at the correct height.


Encountering the E1 error in your LG washing machine can be a frustrating experience, but with the troubleshooting steps provided in this guide, you can resolve the issue effectively. Start by checking the water supply, inspecting the water inlet valve, cleaning the filters, and ensuring proper drainage. By following these solutions, you can get your LG washing machine back to working flawlessly and enjoy hassle-free laundry days.
