Lg Washer Making Grinding Noise When Draining

Introduction

If your LG washer is making a grinding noise while draining, it’s definitely a cause for concern. This unusual sound usually indicates that something is obstructing the drain pump or there might be an issue with the pump itself. Ignoring this problem can lead to further damage, like a completely blocked drain or a burnt-out pump motor. Identifying and addressing the cause promptly can save you from expensive repairs or even the need to replace your washing machine.

Common Causes of LG Washer Making Grinding Noise When Draining

Here are some of the most common culprits behind that grinding noise:

• Foreign Objects: Small items like coins, buttons, or paper clips often find their way into the drain pump.
• Lint Buildup: An excessive amount of lint can accumulate in the drain pump, causing it to strain and make noise.
• Small Clothing Items: Socks or other small pieces of clothing can slip past the tub and get lodged in the drain pump.
• Pump Impeller Obstruction: The drain pump’s impeller (a rotating component that pushes water out) can be blocked by debris.
• Worn Pump Bearings: Over time, the bearings inside the drain pump can wear out, leading to a grinding noise.
• Damaged Pump Housing: Cracks or damage to the pump housing can cause the impeller to rub against the housing, producing a grinding sound.
• Clogged Drain Hose: Although less likely to cause a grinding sound directly, a severely clogged drain hose can put extra strain on the pump.
• Loose Objects in the Tub: Items left in pockets (keys, pens) can cause a grinding noise if they’ve fallen down into areas they shouldn’t be.

Symptoms Checklist

Use this checklist to help pinpoint the issue:

• Grinding noise only occurs during the drain cycle.
• The washer drains slowly or not at all.
• You can hear rattling sounds in addition to the grinding noise.
• The washer displays an error code related to draining.
• The drain hose vibrates excessively during the drain cycle.
• There’s a burning smell coming from the washer.

How to Fix LG Washer Making Grinding Noise When Draining Step-by-Step Guide

Follow these steps to troubleshoot and resolve the issue:

1. Unplug the Washer: Before you start any work, disconnect the washer from the power outlet for safety.
2. Locate the Drain Pump: Typically, the drain pump is located at the bottom front or back of the washer. Consult your washer’s manual for the exact location.
3. Access the Drain Pump: You might need to remove a front or back panel to access the pump. Use a screwdriver to remove the screws holding the panel in place.
4. Drain Remaining Water: Place a shallow pan or towels under the pump area to catch any water that spills out.
5. Inspect the Drain Pump Filter: Many LG washers have a drain pump filter. Carefully unscrew and remove the filter.
6. Clean the Filter: Rinse the filter under running water to remove lint, debris, and any foreign objects.
7. Inspect the Pump Impeller: Use your fingers (or pliers if necessary) to gently rotate the pump impeller. Check for any obstructions or damage.
8. Remove Obstructions: If you find any foreign objects blocking the impeller, carefully remove them.
9. Check the Drain Hose: Disconnect the drain hose from the pump and inspect it for any clogs or kinks. Straighten any kinks and flush out any blockages.
10. Reassemble the Drain Pump: Reinstall the drain pump filter (if applicable) and reattach the drain hose.
11. Reattach the Access Panel: Secure the front or back panel back into place with the screws you removed earlier.
12. Plug in the Washer: Reconnect the washer to the power outlet.
13. Run a Test Cycle: Select a short wash cycle and observe if the grinding noise is gone during the drain phase.
14. Monitor for Leaks: After the test cycle, check for any water leaks around the drain pump area.
15. If Noise Persists: If the noise continues after cleaning the pump, the pump motor may be failing, and further inspection is needed.

Fix the Issue Without Buying Parts

Here are some things you can try before considering replacing parts:

• Washer Reset: Unplug the washer for a few minutes and then plug it back in. This can sometimes reset the system and resolve minor issues.
• Check for Leveling: Ensure the washer is level. An unlevel washer can vibrate excessively and create unusual noises.
• Deep Clean the Washer: Run a washer cleaning cycle with a washing machine cleaner to remove buildup and debris.
• Inspect Hoses: Check all hoses connected to the washer for kinks, cracks, or leaks.

When Replacement Might Be Necessary

If cleaning the drain pump and checking for obstructions doesn’t solve the problem, the drain pump motor itself may be failing. Replacing the drain pump is typically necessary if:. For more related activities, check out our My Samsung Washing Machine Is Leaking From Underneath.
