Whirlpool Washer Making Humming Noise

Introduction

A humming noise coming from your Whirlpool washing machine can be concerning. While it might not always indicate a major problem, ignoring it could lead to further damage. This humming sound often appears during specific cycles, like the spin or drain, and can sometimes be intermittent. Addressing this issue promptly is crucial to prevent potential breakdowns and costly repairs. Let’s explore how to troubleshoot and fix this common problem yourself.

Common Causes of Whirlpool Washer Humming Noise

Several factors can contribute to that annoying humming sound:

Foreign Object Obstruction: Small items like coins, buttons, or socks can get lodged in the pump or drain lines, causing a humming noise.
Worn Pump Motor: The drain pump motor may be wearing out. As it ages, the motor can start to hum louder.
Clogged Drain Pump: Debris buildup in the drain pump can restrict its movement, leading to a humming sound.
Partially Blocked Drain Hose: A kinked or partially blocked drain hose can strain the pump and cause it to hum.
Drive Motor Issues: In some cases, the main drive motor can develop a hum, especially during the spin cycle.
Worn Bearings: Worn or damaged drum bearings can create a humming or grinding noise during spin.
Loose Connections: Loose components within the washer can vibrate and cause a humming sound.
Overloading the Washer: Overloading the washing machine can strain the motor and components, sometimes leading to unusual noises.

Symptoms Checklist

Use this checklist to help identify the source of the humming:

Humming occurs primarily during the drain cycle.
Humming occurs only during the spin cycle.
Humming is continuous throughout the wash cycle.
Humming is accompanied by a burning smell.
Washer vibrates excessively.
Washer is not draining properly.
Water is leaking from the washer.
Humming noise started suddenly after washing a particular load.

How to Fix Whirlpool Washer Making Humming Noise Step-by-Step Guide

Follow these steps to troubleshoot the humming sound:

Unplug the Washer: Always disconnect the power before attempting any repairs. Safety first!
Check the Drain Hose: Inspect the drain hose for kinks or obstructions. Straighten any kinks and remove any visible blockage.
Inspect the Drain Pump Filter: Locate the drain pump filter (usually at the bottom front of the washer behind a small access panel). Open the panel and carefully remove the filter. Clean it thoroughly under running water, removing any lint, debris, or small objects.
Check the Drain Pump: With the filter removed, reach into the drain pump housing (if accessible) and feel for any obstructions. You might be able to dislodge small items stuck in the impeller.
Inspect the Drum for Obstructions: Manually rotate the wash drum. Listen for any unusual noises and check for objects caught between the drum and the outer tub.
Check the Washing Machine Level: An unbalanced machine can vibrate excessively and create noise. Use a level to ensure the washer is level on all sides. Adjust the leveling feet as needed.
Verify Washer Load Size: Avoid overloading the washer. Follow the manufacturer’s guidelines for load size.
Check for Loose Items: Remove all items from the pockets before washing. Small objects like coins and buttons can get lodged in the pump.
Run a Cleaning Cycle: Mineral buildup or soap scum can cause humming. Run a cleaning cycle with a washing machine cleaner according to the manufacturer’s instructions.
Listen Closely During Different Cycles: Run the washer through different cycles (wash, rinse, spin) to pinpoint when the humming occurs. This can help narrow down the source.
Check the Drive Pulley: If you are comfortable, and the washer is unplugged, remove the back panel and inspect the drive pulley and belt for damage or wear. (Consult your washer’s manual for instructions on how to do this).
Check the Motor Mounts: Look for any signs of wear or damage to the motor mounts.

Fix the Issue Without Buying Parts

Before considering replacement parts, try these free fixes:

Reset the Washer: Unplug the washer for 1-2 minutes and then plug it back in. This can sometimes reset the electronic controls.
Cleaning and Maintenance: Regular cleaning cycles and proper loading practices can prevent many noise-related issues.
Recalibration: Some Whirlpool washers have a recalibration cycle. Check your owner’s manual for instructions on how to run this cycle. It can help the machine relearn its operating parameters.
Inspect External Connections: Make sure the water supply hoses are securely connected and not vibrating against the washer cabinet.

When Replacement Might Be Necessary

If the humming persists after troubleshooting, the following parts may need replacing:

Drain Pump: $50 – $150 (USD)
Drive Motor: $150 – $350 (USD)
Drum Bearings: $100 – $250 (USD) (Repair can be labor-intensive)

If any of these components seem damaged or if you are uncomfortable with electrical or mechanical repairs, its best to consult a qualified appliance repair technician.
