Washing Machine Humming Not Draining

Introduction

A washing machine that hums loudly but refuses to drain is a frustrating issue. It means your clothes are stuck in a pool of dirty water, and the laundry process grinds to a halt. This problem usually indicates something is blocking the drainage system or the drain pump is malfunctioning. Addressing it promptly can prevent water damage and further complications, saving you money and headaches in the long run. Ignoring it might lead to a flooded laundry room or a more expensive repair down the line.

Common Causes of Washing Machine Humming Not Draining

Here are some of the most common reasons why your washing machine might be humming but not draining:

Clogged Drain Hose: The drain hose is responsible for carrying the water out of the machine. If it gets kinked, bent, or blocked with lint and debris, it will prevent proper drainage.
Clogged Drain Pump Filter: Most washing machines have a filter that catches lint, hair, and small objects before they reach the drain pump. When this filter becomes clogged, it restricts water flow.
Faulty Drain Pump: The drain pump is the motor responsible for pushing the water out. If the pump motor is broken or jammed, it will hum but won’t be able to pump the water.
Blocked Drainpipe: The drainpipe where your washing machine’s hose connects can also get clogged. A blockage here can cause the water to back up.
Kinked or Twisted Drain Hose: A simple kink in the drain hose can severely restrict or block water flow.
Overloading the Washing Machine: Putting too many clothes in the machine can sometimes strain the drain pump and prevent it from functioning correctly.
Foreign Objects in the Pump: Small items like coins, buttons, or socks can sometimes find their way into the drain pump and jam it.
Wiring Issues: Less common, but electrical problems related to the drain pump circuit can cause it to hum without working.

Symptoms Checklist

Use this checklist to verify your washing machine issue:

The washing machine is making a humming or buzzing noise.
The drum is full of water after the wash cycle.
The water is not draining at all, or draining very slowly.
You might see an error code related to drainage on the machine’s display.
The drain hose feels cold even though the water inside should be lukewarm.

How to Fix Washing Machine Humming Not Draining Step-by-Step Guide

Unplug the Washing Machine: Safety first! Disconnect the power cord from the outlet before starting any troubleshooting.
Locate the Drain Hose: It’s usually at the back of the washing machine. Carefully detach it from the drainpipe in the wall.
Inspect the Drain Hose: Check for any kinks, twists, or visible blockages. Straighten any kinks.
Flush the Drain Hose: Hold the drain hose over a bucket and try to flush it out with water. You can use a garden hose gently. If you find a blockage, try to dislodge it with a long, flexible object like a straightened coat hanger (be careful not to puncture the hose).
Locate the Drain Pump Filter: This is usually located at the front bottom of the machine, behind a small access panel. Consult your owner’s manual if you can’t find it.
Prepare for Water: Place a shallow pan or towels under the access panel to catch any water that may spill out.
Open the Access Panel and Remove the Filter: Carefully unscrew or twist the filter cap (refer to your manual).
Clean the Drain Pump Filter: Remove any lint, hair, coins, or other debris from the filter. Rinse it thoroughly with water.
Inspect the Drain Pump Area: Look inside the drain pump housing for any obstructions. You may need a flashlight. Try to gently turn the pump impeller (the fan-like part) with your finger to see if it spins freely.
Reinstall the Filter: Securely screw or twist the filter cap back into place.
Reconnect the Drain Hose: Attach the drain hose back to the drainpipe, making sure it’s securely connected.
Check the Drainpipe: Ensure the drainpipe isn’t clogged. You can try using a plumbing snake to clear any blockage.
Level the Washing Machine: Make sure the washing machine is level. An unleveled machine can sometimes cause drainage issues. Adjust the feet at the bottom of the machine to level it.
Plug in the Washing Machine: Reconnect the power cord.
Run a Test Cycle: Select a short drain and spin cycle to see if the washing machine drains properly.

Fix the Issue Without Buying Parts

Often, you can resolve the “humming not draining” problem without spending any money:

Reset the Washing Machine: Unplug the machine for 5-10 minutes, then plug it back in. This can sometimes reset the control panel and clear errors.
Check for Kinks Regularly: Inspect the drain hose periodically to prevent kinks from forming.
Proper Loading: Avoid overloading the washing machine to prevent strain on the drain pump.
Preventative Cleaning: Run a washing machine cleaner cycle (with a commercial cleaner or a mixture of vinegar and baking soda) every month to remove buildup.

When Replacement Might Be Necessary

If you’ve tried all the troubleshooting steps and the washing machine still isn’t draining, the drain pump itself might be faulty. Replacing the drain pump can cost between $50 and $200, depending on the model. The drain pump and the washing machine timer are the most frequently replaced parts when this issue arises.

Safety Warning

Always unplug the washing machine before attempting any repairs.
Be careful when handling water to avoid electrical shock.
Wear gloves to protect your hands from dirt and bacteria.
Clean up any spilled water immediately to prevent slips and falls.
