Lg Washing Machine Won T Stop Filling With Water

Introduction

Is your LG washing machine continuously filling with water, even when it’s not supposed to be? This is a frustrating issue that can lead to water damage and a hefty water bill. Imagine starting a load of laundry only to find water spilling out onto your floor! Addressing this problem quickly is crucial to prevent further damage and get your washing machine back in working order. This guide will walk you through the most common causes and simple steps you can take to resolve the issue yourself.

Common Causes of lg washing machine won t stop filling with 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 continuously enter.
• Pressure Switch Malfunction: The pressure switch senses the water level. If it’s not working correctly, it won’t signal the machine to stop filling.
• Air Dome Obstruction: The air dome, connected to the pressure switch, can get clogged with soap scum or debris, affecting pressure readings.
• Defective Water Level Sensor: Similar to the pressure switch, this sensor monitors the water level and can malfunction.
• Siphon Effect: If the drain hose is too low in the drainpipe, it can create a siphon effect, continuously pulling water into the machine.
• Control Board Issues: In rare cases, the control board (the “brain” of the machine) can be faulty and send incorrect signals to the water inlet valve.
• Incorrect Hose Installation: Sometimes the drain hose is not positioned correctly, causing water to keep filling.
• Damaged or Kinked Hoses: Damaged hoses can leak or not function as expected.

Symptoms Checklist

Use this checklist to accurately identify the issue:

• Water continuously flows into the machine, even when it’s off.
• The water level rises above the normal fill line.
• Water overflows from the machine.
• The washing machine makes unusual noises during the filling process.
• The washing machine doesn’t start the wash cycle because the water level is too high.
• Water drains slowly or not at all.

How to Fix lg washing machine won t stop filling with water Step-by-Step Guide

1. Unplug the Washing Machine: Safety first! Disconnect the power cord from the outlet.
2. Turn Off Water Supply: Locate the hot and cold water shut-off valves behind the washing machine and turn them off.
3. Inspect the Drain Hose: Make sure the drain hose is properly inserted into the drainpipe and isn’t too far down. Ideally, it should be a few inches inside the drainpipe. Ensure the hose isn’t kinked or damaged.
4. Check for Siphon Effect: If the drain hose extends too far into the drainpipe, it can create a siphon. Adjust the hose position.
5. Clean the Drainpipe: A clogged drainpipe can prevent proper drainage and cause the machine to overfill. Use a drain snake or plumber’s auger to clear any obstructions.
6. Locate the Water Inlet Valve: This is usually located on the back of the washing machine, where the water hoses connect.
7. Inspect the Water Inlet Valve Screens: Disconnect the water hoses and check the small screens inside the valve inlets for debris. Clean them with a brush and rinse them thoroughly.
8. Check the Air Dome: This is usually a small chamber connected to the pressure switch. Locate it and check if it’s blocked. Cleaning it is a good idea.
9. Locate the Pressure Switch: Typically found near the top of the washing machine cabinet.
10. Check Pressure Switch Hose: Disconnect the hose from the pressure switch and blow gently into it. You should hear a faint click. Check for any cracks or damage to the hose.
11. Reconnect Hoses and Power: Reconnect all hoses securely and plug the washing machine back in.
12. Run a Test Cycle: Select a small load setting and start the washing machine to see if the problem is resolved.
13. Reset your washing machine: Unplug your washing machine for one minute then plug it back in.
14. Check Water Level Sensor: If you have some advanced knowledge, you can check the water level sensor continuity with multimeter.

Fix the Issue Without Buying Parts

Often, you can resolve the issue without purchasing new parts. Here are some free methods:

• Reset the Washing Machine: Unplug the machine for 5 minutes, then plug it back in. This can sometimes reset the control board.
• Clean the Water Inlet Valve Screens: Regularly cleaning these screens prevents debris buildup.
• Check and Adjust Drain Hose Position: Ensure the drain hose is properly positioned to prevent siphoning.
• Inspect All Hoses: Look for kinks, cracks, or blockages in all hoses connected to the machine.
• Run a calibration cycle (check the washing machine’s manual).

When Replacement Might Be Necessary

If the problem persists after trying the above steps, a part replacement might be necessary. The most common parts that fail are the water inlet valve (estimated cost: $30-$75 USD), the pressure switch/water level sensor (estimated cost: $20-$60 USD), or, rarely, the control board (estimated cost: $100-$300 USD). Consult a qualified technician if you’re unsure about replacing these parts yourself. For more related activities, check out our My Lg Front Load Washer Won T Turn On.

FAQ

Here are some frequently asked questions about washing machine overfilling:

• Q: Why is my washing machine filling with water when it’s turned off? A: This is usually caused by a faulty water inlet valve that’s stuck open.
• Q: How do I know if my pressure switch is bad? A: If the washing machine overfills and doesn’t stop, the pressure switch may be faulty. Testing it with a multimeter can confirm this.
• Q: Can a clogged drain cause overfilling? A: Yes, a clogged drain can prevent proper drainage, leading to overfilling.
• Q: Is it safe to use the washing machine if it’s overfilling? A: No, it’s not safe. Overfilling can cause water damage and potentially electrical hazards. Turn off the water and unplug the machine until the problem is resolved.
• Q: How do I test the water inlet valve? A: Disconnect the valve and check if water continues to flow with the power off. If it does, the valve needs replacing.
