Washing Machine Making Noise When Draining

Introduction

A noisy washing machine, especially during the drain cycle, is a common and often alarming problem. The draining process shouldn’t sound like a jet engine taking off! This noise indicates something is interfering with the normal operation of the drain pump and system. Ignoring this issue can lead to more significant problems, like water damage to your laundry room or complete failure of the drain pump. Addressing it promptly can save you money and prevent further damage. It’s important to find the source of the sound so you can fix it before a minor annoyance becomes a major headache.

Common Causes of Washing Machine Making Noise When Draining

Here are some of the most common reasons why your washing machine might be making noise during the drain cycle:

Clogged Drain Pump Filter: This is the most frequent culprit. Small objects like coins, buttons, or lint can get trapped in the filter, obstructing the flow of water.
Obstructed Drain Hose: Kinks, bends, or clogs in the drain hose can restrict water flow and cause the pump to work harder, creating noise.
Worn or Damaged Drain Pump: Over time, the drain pump’s impeller (the rotating part) can wear down or become damaged.
Loose Objects in the Tub: Small items like socks or undergarments can sometimes slip into the space between the inner tub and outer tub, creating noise during draining.
Foreign Objects in the Drain Pump Housing: Even if the filter is clear, small debris can sometimes bypass it and lodge directly in the pump housing.
Air in the Drain System: If air gets trapped in the drain system, it can cause the pump to cavitate (form air bubbles) and make a gurgling or rattling sound.
Partially Blocked Drainpipe: Your house’s drainpipe that the washing machine drains into might be partially clogged.

Symptoms Checklist

Use this checklist to accurately identify the issue:

Loud grinding or buzzing noise specifically during the drain cycle.
Slower than usual draining.
Standing water remaining in the tub after the cycle finishes.
The machine stops mid-cycle, displaying an error code related to draining.
The drain hose vibrates excessively during draining.
You find small objects like coins or buttons in the washer tub.
The noise worsens over time.

How to Fix Washing Machine Making Noise When Draining Step-by-Step Guide

Here’s a step-by-step guide to troubleshoot the problem:

Unplug the Washing Machine: Always disconnect the power before working on any appliance.
Locate the Drain Pump Filter: This is usually located at the front bottom corner of the machine, behind a small access panel. Consult your owner’s manual if you can’t find it.
Prepare for Water Spillage: Place a shallow pan or towels underneath the access panel, as some water will likely spill out.
Open the Access Panel and Remove the Filter: Carefully unscrew or unclip the access panel. Then, unscrew and remove the drain pump filter. Some models have a small hose you need to drain first.
Clean the Filter: Thoroughly clean the filter under running water, removing any lint, debris, or foreign objects.
Inspect the Drain Pump Housing: Shine a flashlight into the drain pump housing to check for any obstructions that may have bypassed the filter. Use pliers or tweezers to carefully remove any visible debris.
Reinstall the Filter: Make sure the filter is securely screwed back into place.
Close the Access Panel: Secure the access panel.
Check the Drain Hose: Locate the drain hose at the back of the machine. Disconnect it from the drainpipe.
Inspect the Drain Hose for Kinks or Clogs: Straighten any kinks in the hose. Shine a light through the hose to check for blockages.
Flush the Drain Hose: If you suspect a clog, flush the hose with water from a garden hose or sink faucet to dislodge any debris.
Check the Drainpipe: Ensure that the house drainpipe the washing machine drains into is clear. Clogs in the house piping system will affect drainage.
Reconnect the Drain Hose: Securely reattach the drain hose to the drainpipe.
Plug in the Washing Machine: Reconnect the power.
Run a Test Cycle: Run a short wash and drain cycle to see if the noise is gone.

Fix the Issue Without Buying Parts

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

Reset the Washing Machine: Unplug the machine for 5-10 minutes, then plug it back in. This can sometimes reset the electronic controls and resolve minor issues.
Clean the Tub Thoroughly: Run an empty wash cycle with a washing machine cleaner to remove any buildup that might be contributing to the noise.
Inspect the Machine’s Level: Make sure your washing machine is level. An unbalanced machine can cause excessive vibration and noise. Use a level and adjust the feet as needed.
Avoid Overloading: Overloading the washing machine can strain the motor and pump, leading to noise. Follow the manufacturer’s guidelines for load capacity.

When Replacement Might Be Necessary

If the noise persists after cleaning the filter and drain hose, the drain pump itself may be failing. A new drain pump typically costs between $50 and $150 USD, depending on the model. Common symptoms of a failing drain pump include a constant loud buzzing noise, the pump failing to drain the water completely, or the pump stopping altogether. If you are not comfortable replacing the pump yourself, it’s best to call a qualified appliance repair technician. Bearings, impellers or the motor itself are often sources of washing machine noise.

Safety Warning

Always unplug the washing machine from the power outlet before performing any maintenance or repairs.
Be careful when handling water, as spills can create slippery surfaces.
If you are not comfortable working with electrical appliances, consult a qualified appliance repair technician.
Wear gloves to protect your hands from dirt and debris.
