LG Washing Machine E4 Error Code Solution
The E4 error code on an LG washing machine typically indicates a water overflow issue, meaning the machine has detected more water than it can safely handle. This error triggers a safety stop to prevent water from leaking onto your floor.
Troubleshooting the E4 Overflow Error
- Check the water inlet valve for debris or calcium buildup that may prevent it from closing completely, causing water to continue flowing even when the machine is off.
- Inspect the water level sensor (pressure switch) and its plastic tubing for any cracks, blockages, or loose connections that might send incorrect signals to the control board.
- Ensure the drain hose is positioned correctly and not clogged, as a slow drain can sometimes cause the system to miscalculate water levels.
Safe Steps to Try Before Calling a Technician
- Turn off the water supply taps connected to the machine immediately to stop the overflow.
- Unplug the washing machine from the power outlet to reset the control board and ensure your safety during inspection.
- Clean the drain filter located at the bottom front of the machine to ensure there are no obstructions preventing proper water drainage.
Always unplug the appliance from the power source before opening any panels or touching internal components to avoid the risk of electric shock.

Frequently Asked Questions
What does the E4 error code mean on my LG washing machine?
The E4 error code specifically indicates a water overflow fault, meaning the water level inside the drum has exceeded the maximum safety limit.
Can I fix the E4 error myself?
You can perform basic checks like cleaning the drain filter and ensuring the inlet valve is closed, but if the issue persists, it may involve a faulty sensor or control board requiring professional repair.
Why does my washing machine keep filling with water even when turned off?
This is usually caused by a faulty water inlet valve that is stuck in the open position, allowing water to bypass the control system.
Should I keep using the machine if it shows E4?
No, you should stop using the machine immediately to prevent potential water damage to your home and further electrical damage to the appliance.
