If your LG top load washing machine is overflowing or keeps filling with water even after you’ve unplugged it, the cause is almost always one failed part: the water inlet valve. Replacing it yourself is straightforward and inexpensive.
Why Your LG Washer Won’t Stop Filling With Water
The water inlet valve is an electrically controlled valve that opens to allow water into the washing machine and closes when the correct water level is reached. When the valve fails — usually due to a worn internal diaphragm or debris buildup — it can get stuck in the open position and water flows freely regardless of what the control board tells it to do.
The Key Clue: Water Flows Even When Unplugged
If water continues flowing into the washer even after you unplug it from the wall, the valve has mechanically failed. Since the valve is electrically controlled, unplugging the machine should stop all water flow immediately. If it doesn’t, the valve is stuck open and must be replaced.
What to Do Immediately If Your Washer Is Overflowing
- Turn off the water supply valves behind the washing machine — turn both hot and cold valves clockwise until they stop
- Unplug the washing machine from the wall
- Mop up standing water immediately to prevent floor damage and mold

How to Replace the LG Top Load Washer Water Inlet Valve
Step 1: Unplug and Disconnect Water Supply
Make sure the machine is unplugged and both water supply valves are fully closed. Disconnect the hot and cold water hoses from the back of the machine.
Step 2: Access the Water Inlet Valve
On most LG top load washers the water inlet valve is located at the back of the machine near the top. You may need to remove the back panel to access it fully.
Step 3: Disconnect and Remove
Take a photo of the wire harness connectors before disconnecting. Press the tab on each connector and pull firmly to disconnect. Unscrew the mounting screws and remove the internal hoses using pliers to release the clamps.
Step 4: Install the New Valve and Test
Connect the internal hoses to the new valve and secure the clamps. Mount the new valve and reconnect the wire harness connectors. Reattach the external water supply hoses, turn the supply valves back on slowly, plug the machine back in and run a short wash cycle.
