Lg Washer Not Draining Top Load

Introduction

Discovering that your LG top-load washer isn’t draining properly can be a real headache. A washer full of water means your clean laundry is sitting in a soggy mess, and the machine can’t be used for another load. This issue needs attention quickly to prevent mold, mildew, and potential damage to your clothing and the appliance itself. Fortunately, many common causes can be easily addressed at home without needing to call a professional immediately.

Common Causes of lg washer not draining top load

Several factors can prevent your LG top-load washer from draining correctly:

Clogged Drain Hose: The hose that carries water away from the washer can get blocked with lint, small objects (like socks!), or debris.
Obstructed Drain Pump: The drain pump, responsible for pushing water out, can be clogged with similar materials.
Kinked or Bent Drain Hose: A kink in the drain hose restricts water flow.
Faulty Lid Switch: The washer might not drain if the lid switch (which tells the machine the lid is closed) is malfunctioning.
Drain Pump Motor Failure: The drain pump motor itself could be burned out or damaged.
Clogged Air Gap (if applicable): Some plumbing systems have an air gap that can become clogged, preventing proper drainage.
Standing Water in Drain Pipe: Sometimes the issue isn’t with the washer, but with the drainpipe in the wall that the washer empties into. If the pipe is clogged, the washer can’t drain.
Control Board Malfunction: Although less common, a problem with the washer’s control board can prevent the drain cycle from activating.

Symptoms Checklist

Confirm the issue by checking for these signs:

The washer tub is full of water after the wash cycle completes.
You hear a humming noise during the drain cycle, but no water is being pumped out.
The washer displays an error code related to draining (check your owner’s manual).
The drain hose is visibly kinked or blocked.
Water is draining very slowly or not at all.

How to Fix lg washer not draining top load Step-by-Step Guide

Follow these steps to troubleshoot the problem:

Unplug the Washer: Safety first! Disconnect the washer from the power outlet.
Check the Drain Hose for Kinks: Make sure the drain hose isn’t bent or kinked. Straighten it out if necessary.
Inspect the Drain Hose Connection: Ensure the hose is securely connected to both the washer and the drainpipe.
Remove the Drain Hose from the Drainpipe: Carefully detach the hose from the drainpipe. Place the end of the hose into a bucket or large container.
Run a Short Drain Cycle: Turn the washer on, select a short drain cycle, and see if water comes out of the hose into the bucket. This will tell you if the blockage is in the hose or further down the line.
Clean the Drain Hose: If the water flow is weak or nonexistent, the hose is likely clogged. Disconnect the hose completely and flush it out with a garden hose. You can also use a long, flexible brush to remove debris.
Check the Drainpipe: If the hose drains freely into the bucket, the problem might be with the drainpipe in the wall. You can try using a plumbing snake or a drain cleaner to clear any blockages.
Locate the Drain Pump: Refer to your owner’s manual for the location of the drain pump. It’s usually at the bottom of the washer, behind an access panel.
Access the Drain Pump: Carefully remove the access panel. You might need a screwdriver.
Check the Drain Pump Filter: Most LG washers have a filter on the drain pump. Remove the filter (be prepared for some water to spill) and clean out any lint, hair, or debris.
Inspect the Drain Pump Impeller: With the filter removed, you should be able to see the impeller (the part that spins to pump water). Make sure it’s not blocked by anything. You can try turning it gently with your finger to ensure it spins freely.
Reassemble the Drain Pump and Hose: Put the filter back in place, reattach the drain hose, and secure the access panel.
Plug the Washer Back In: Reconnect the washer to the power outlet.
Run a Test Cycle: Run a short wash and drain cycle to see if the problem is resolved.

Fix the Issue Without Buying Parts

Here are some things to try that don’t require buying new parts:

Reset the Washer: Unplug the washer for 5-10 minutes, then plug it back in. This can sometimes reset the control board and clear minor errors.
Clean the Washer Regularly: Run a cleaning cycle with a washing machine cleaner or white vinegar every month to prevent buildup of soap scum and debris.
Check for Error Codes: Consult your owner’s manual for a list of error codes and their corresponding solutions.
Reduce Detergent Use: Using too much detergent can lead to excessive suds, which can interfere with the draining process.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and the washer still isn’t draining, the drain pump motor itself might be faulty. Replacing the drain pump is an option, typically costing between $50 and $150, depending on the model. Another potential culprit is the lid switch, which can be replaced for a similar price. In rare cases, a malfunctioning control board might require replacement, which can be more expensive, ranging from $150 to $300. Before replacing any parts, it’s worth getting a professional diagnosis to confirm the problem.

Safety Warning

Always unplug the washer from the power outlet before performing any repairs.
Be careful when handling water. Mop up any spills immediately to prevent slips and falls.
If you’re uncomfortable working with electrical appliances, contact a qualified technician.
Do not attempt to disassemble any components you are not familiar with.
