Clothes Washer Not Draining

Introduction

A washing machine refusing to drain is a common and frustrating household problem. It leaves your clothes soaking wet, your laundry room potentially flooded, and prevents you from starting another load. Addressing this issue quickly is important to prevent mold growth, damage to your washing machine, and further inconvenience. Many times, the fix is simpler than you think and doesn’t require a professional.

Common Causes of clothes washer not draining

Here are some frequent reasons why your washing machine might not be draining properly:

Clogged Drain Hose: The hose that carries water away from the washer can become blocked with lint, debris, or small items.
Clogged Drain Pump Filter: Many washing machines have a filter to catch lint and small objects before they reach the drain pump. This filter can become clogged.
Kinked or Blocked Drain Hose: A kink in the hose restricts water flow. Similarly, something pressing on the hose can cause a blockage.
Faulty Drain Pump: The drain pump is responsible for pushing water out of the washer. If it’s broken, it won’t work.
Lid Switch Problems: Some washing machines won’t drain if the lid switch (which detects if the lid is closed) is malfunctioning.
Blocked Standpipe: The standpipe where the drain hose empties into your house’s plumbing can be clogged.
Air Lock in Drain Hose: Air trapped in the drain hose can prevent water from flowing out.
Control Panel Malfunction: In rare cases, the washing machine’s control panel can malfunction, preventing it from signaling the drain pump to activate.

Symptoms Checklist

Use this checklist to help pinpoint the problem:

The washing machine cycle finishes, but water remains in the drum.
You hear a humming or buzzing sound during the drain cycle, but no water is being pumped out.
The washing machine displays an error code related to draining.
Water drains very slowly.
There’s water leaking around the drain hose or drain pump.

How to Fix clothes washer not draining Step-by-Step Guide

Unplug the Washing Machine: Always disconnect the power before attempting any repairs.
Locate the Drain Hose: It’s usually at the back of the machine.
Check for Kinks: Straighten out any kinks in the drain hose.
Detach the Drain Hose: Carefully disconnect the drain hose from both the washing machine and the standpipe. Have a bucket ready to catch any remaining water.
Flush the Drain Hose: Run water through the drain hose to dislodge any clogs. You can use a garden hose or a sink faucet. Look for debris coming out.
Check the Standpipe: If the drain hose is clear, check the standpipe for clogs. Use a drain snake or auger to clear any blockages.
Locate the Drain Pump Filter: Consult your washing machine’s manual to find the location of the drain pump filter. It’s often at the front bottom of the machine, behind a small access panel.
Clean the Drain Pump Filter: Carefully remove the filter and clean it thoroughly. Remove any lint, hair, or small objects.
Check the Drain Pump: With the filter removed, you may be able to see the drain pump impeller (a small fan-like blade). Make sure it’s not blocked by anything. You can gently try to turn it with your finger (unplugged, of course!).
Reattach the Drain Hose: Reconnect the drain hose to both the washing machine and the standpipe, ensuring it’s securely attached.
Check the Lid Switch: Ensure the lid switch is functioning properly. You can test it by manually pressing it down and listening for a click (with the machine unplugged).
Reset the Washing Machine: Some washing machines can be reset by unplugging them for a few minutes and then plugging them back in.
Run a Test Cycle: Select a short wash cycle and observe if the washing machine drains properly.

Fix the Issue Without Buying Parts

Many draining issues can be resolved without spending money:

Regular Cleaning: Run an empty wash cycle with a cup of white vinegar every month to prevent buildup.
Lint Trap Maintenance: Regularly clean your lint trap to minimize clogs.
Proper Hose Placement: Make sure the drain hose isn’t pushed too far into the standpipe, which can create a siphon effect and prevent draining.
Inspect Regularly: Periodically check the drain hose and filter for any signs of wear and tear or blockage.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and your washing machine still won’t drain, you might need to consider replacing a part. The drain pump is a common culprit, and replacement typically costs between $50 and $200, including labor. In some cases, a faulty control panel could be the issue, but this is usually a more expensive repair, ranging from $150 to $400. In extreme cases where the machine is very old, consider whether the cost of a new machine outweighs the repair costs.

Safety Warning

Always unplug the washing machine from the power outlet before attempting any repairs.
Be careful when handling water, as it can create a slip hazard. Clean up any spills immediately.
If you’re not comfortable performing any of these repairs, contact a qualified appliance repair technician.
Never attempt to repair a washing machine while it’s running.
