Mystery Solved! Why Does My Lg Dishwasher Keep Filling Up With Water?

If you’ve noticed a pool of water at the bottom of your LG dishwasher, you’re not alone. This common issue can be frustrating and leave you wondering why it’s happening. In this comprehensive guide, we’ll delve into the potential causes and provide practical solutions to help you resolve the problem.

Common Causes of Water in the Bottom of an LG Dishwasher

• Drain Hose Clog: Blockages in the drain hose can prevent water from draining properly, leading to accumulation at the bottom.
• Clogged Drain Pump: If the drain pump is clogged with food debris or other particles, it may fail to pump out water effectively.
• Faulty Check Valve: The check valve, located at the connection between the drain hose and the dishwasher, prevents water from backflowing into the dishwasher. A faulty check valve can allow water to leak back in.
• Leaking Door Gasket: A damaged or worn-out door gasket can allow water to seep into the dishwasher during the wash cycle.
• Overloading: Packing too many dishes into the dishwasher can prevent water from circulating properly and lead to water pooling at the bottom.
• Faulty Float Switch: The float switch detects the water level in the dishwasher and triggers the drain pump when the water reaches a certain height. A faulty float switch may not activate the drain pump properly, resulting in standing water.
• Clogged Spray Arms: Clogged spray arms can restrict water flow and prevent dishes from being cleaned thoroughly. This can lead to water accumulating at the bottom of the dishwasher.

Troubleshooting and Solutions

1. Check the Drain Hose

• Disconnect the drain hose from the dishwasher and inspect it for any clogs or kinks.
• If there are any blockages, remove them and reconnect the hose.

2. Clean the Drain Pump

• Locate the drain pump at the bottom of the dishwasher and unscrew the cap.
• Use a small brush or tweezers to remove any debris from the pump impeller.
• Reinstall the cap and reconnect the drain hose.

3. Inspect the Check Valve

• Disconnect the drain hose from the dishwasher and check the check valve for damage or debris.
• Replace the check valve if it’s faulty.

4. Replace the Door Gasket

• Inspect the door gasket for any tears or gaps.
• If the gasket is damaged, replace it with a new one.

5. Avoid Overloading the Dishwasher

• Load dishes in a way that allows for proper water circulation.
• Avoid cramming too many dishes into the dishwasher.

6. Test the Float Switch

• Pour a few cups of water into the dishwasher and observe if the drain pump activates.
• If the drain pump doesn’t turn on, replace the float switch.

7. Clean the Spray Arms

• Remove the spray arms from the dishwasher and inspect them for any clogs.
• Use a toothpick or pipe cleaner to remove any debris from the spray arm holes.

Preventing Water Accumulation in the Future

• Regularly clean the drain hose, drain pump, and spray arms.
• Avoid overloading the dishwasher.
• Use a dishwasher cleaner monthly to remove any buildup.
• Inspect the door gasket periodically and replace it if necessary.
