Lg Washing Machine Does Not Stop Filling Water

Introduction

Discovering your LG washing machine continuously filling with water can be alarming. It means your washing machine isnt recognizing that it’s reached the correct water level and won’t move onto the wash cycle. This not only wastes water and energy, increasing your utility bills, but can also lead to flooding and damage to your laundry room. Addressing this promptly is essential to prevent further issues and protect your home from water damage. Lets tackle this problem with a few simple steps.

Common Causes of lg washing machine does not stop filling water

Here are some of the most frequent reasons why your LG washing machine might be overfilling:

• Faulty Water Inlet Valve: This valve controls the flow of water into the machine. If it’s stuck open, water will continue to flow even when it shouldn’t.
• Pressure Switch Malfunction: The pressure switch senses the water level. If it’s defective, it may not signal the machine to stop filling.
• Air Dome/Hose Obstruction: A blocked or kinked air dome or hose leading to the pressure switch can prevent accurate water level sensing.
• Defective Water Level Sensor: Similar to the pressure switch, this sensor directly measures the water level and can fail.
• Control Board Issues: In some cases, a malfunctioning control board can send incorrect signals to the water inlet valve.
• Drain Hose Problems: If the drain hose is positioned too low, it can create a siphoning effect, causing the machine to continuously fill and drain simultaneously.
• Clogged Drain Line: A blockage in the drain system can prevent the machine from recognizing the water level correctly.
• Loose Wiring Connections: Check the wiring connected to the water inlet valve and pressure switch. Loose connections can cause erratic behavior.

Symptoms Checklist

Use this list to help you confirm that your LG washing machine is indeed experiencing this issue:

• Water continues to fill even after the wash cycle should have started.
• The water level exceeds the normal fill line inside the drum.
• You might hear the water running constantly.
• The machine doesn’t proceed to the wash cycle and stays in the filling stage.
• The washing machine may overflow if left unattended.

How to Fix lg washing machine does not stop filling water Step-by-Step Guide

Follow these steps to troubleshoot and hopefully fix your LG washing machine:

1. Unplug the Washing Machine: Always start by disconnecting the power to avoid electrical shock.
2. Inspect the Drain Hose: Ensure the drain hose is properly positioned and not inserted too far into the drainpipe. It should have an air gap to prevent siphoning. A height of about 30-40 inches is generally recommended.
3. Check for Kinks in the Drain Hose: Make sure the drain hose isn’t kinked or blocked, which can restrict drainage.
4. Examine the Water Inlet Hoses: Check the hoses connected to the water supply. Look for any kinks, blockages, or leaks.
5. Clean the Water Inlet Valve Screens: Locate the water inlet valves at the back of the machine where the water hoses connect. Turn off the water supply, disconnect the hoses, and carefully remove and clean the small screens inside the valve openings.
6. Locate the Pressure Switch: This is usually a small, round component with a hose attached, often located near the top of the machine. Consult your owner’s manual for the exact location.
7. Inspect the Air Dome/Hose: Check the hose connecting the pressure switch to the tub (air dome). Ensure it’s not kinked, clogged, or disconnected. Gently blow into the hose to check for obstructions.
8. Check for Loose Connections: Examine the wiring connections to the water inlet valve, pressure switch, and control board. Ensure they are secure and not corroded.
9. Try a Power Cycle: Plug the machine back in, wait a few minutes, and then unplug it again. This can sometimes reset the control board.
10. Initiate a Calibration Cycle (If Available): Some LG washers have a calibration or test cycle. Consult your owner’s manual on how to start this cycle. This can help the machine relearn the correct water levels.
11. Run a Test Cycle: Select a small load size and a quick wash cycle. Observe if the machine fills properly and progresses through the cycle as it should.
12. Check the Drain Pump Filter: A clogged filter can impact water level sensing. Locate and clean the drain pump filter (usually at the bottom front of the machine).

Fix the Issue Without Buying Parts

Before considering replacement parts, try these free methods:

• Reset the Machine: Unplug the washer for at least 10 minutes to reset the control board.
• Clean the Inlet Valve Screens: As described above, cleaning these screens can often resolve filling issues.
• Check Hose Connections: Ensure all hoses are properly connected and free from kinks or obstructions.
• Level the Washing Machine: Make sure the machine is level. An unlevel machine can sometimes cause water level sensing problems.
• Review Your Owner’s Manual: Your manual may have specific troubleshooting steps or reset procedures for your model.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and the problem persists, you might need to replace a part. Here are some common parts that fail and their approximate cost (USD):

• Water Inlet Valve: $30 – $70
• Pressure Switch: $20 – $50
• Water Level Sensor: $30 – $60
• Control Board: $100 – $300 (Consider professional repair if the board is suspected.)

Safety Warning

Always prioritize safety when working with appliances:

• Unplug the Appliance: Disconnect the power cord before any inspection or repair.
• Water and Electricity Don’t Mix: Avoid contact with water when the machine is plugged in.
• Wet Floors: Be cautious of slippery floors due to water leaks. Clean up any spills immediately.
• Consult a Professional: If you’re uncomfortable with any of these steps, consult a qualified appliance repair technician.

Tools You May Need

Here are some tools that might be helpful:

• Screwdrivers (Phillips and Flathead)
• Pliers
• Adjustable Wrench
• Bucket
• Towels
• Small Brush for Cleaning Screens

FAQ

Here are some frequently asked questions about washing machine filling problems:

• Q: Why is my washing machine filling slowly?
  A: A slow fill rate is often caused by low water pressure, partially closed inlet valves, or clogged inlet valve screens.
• Q: Can I use hot water to clean the inlet valve screens?
  A: No, use cold water and a soft brush to avoid damaging the screens.
• Q: How do I know if my pressure switch is bad?
  A: If the machine continues to fill even when you manually blow into the air hose connected to the pressure switch (with the machine unplugged), the switch may be faulty.
• Q: My washing machine fills and drains at the same time. What’s wrong?
  A: This is typically caused by a siphoning effect due to an improperly positioned drain hose. Make sure the hose has a proper air gap.

Conclusion

Troubleshooting a washing machine that won’t stop filling can seem daunting, but by following these steps, you can often identify and resolve the issue yourself. Remember to always prioritize safety and consult your owner’s manual for specific instructions related to your LG model. If you’ve exhausted these steps and the problem persists, don’t hesitate to call a qualified appliance repair technician for professional assistance. Good luck!
