Whirlpool Washer Makes Humming Sound

Introduction

A humming sound coming from your Whirlpool washing machine can be unsettling, especially when its not during the normal wash cycle. This usually indicates an issue with one of the washer’s components trying to function but encountering resistance. Ignoring the hum could lead to more significant problems and potentially damage other parts of your appliance. Addressing this issue promptly can save you money and extend the life of your washing machine. It’s often more urgent if the humming is accompanied by other symptoms like a burning smell or if the washer is not filling/draining correctly.

Common Causes of Whirlpool Washer Makes Humming Sound

Here are some common reasons why your Whirlpool washer might be making a humming sound:

• Blocked Drain Pump: An obstruction in the drain pump, such as lint, a small sock, or debris, can cause the motor to hum as it tries to pump water.
• Faulty Drain Pump Motor: The motor itself might be failing, causing a hum as it struggles to operate.
• Stuck or Worn Drive Motor: The main motor that spins the drum may be struggling due to worn bearings or being stuck.
• Obstructed Water Inlet Valve: Debris in the water inlet valve can restrict water flow, making a humming noise as the valve attempts to open.
• Worn or Damaged Bearings: Worn bearings in the motor or drum can cause a humming noise, especially during the spin cycle.
• Belt Issues (if applicable): Some older models use a belt to drive the drum. A worn, loose, or broken belt can cause a humming or squealing sound.
• Foreign Object in the Tub: An object lodged between the inner and outer tubs can create friction and noise.
• Pressure Switch Malfunction: A faulty pressure switch, which regulates the water level, might be sending incorrect signals, causing the motor to hum.

Symptoms Checklist

Check if any of these symptoms accompany the humming sound:

• Humming occurs during the fill cycle.
• Humming occurs during the drain cycle.
• Humming is loudest during the spin cycle.
• The washing machine is vibrating excessively.
• The washing machine is not filling with water.
• The washing machine is not draining water.
• The washing machine smells like burning rubber.
• Error codes are displayed on the control panel.

How to Fix Whirlpool Washer Makes Humming Sound Step-by-Step Guide

Important: Always unplug your washing machine before attempting any repairs.

1. Unplug the Washing Machine: This is the most important step for your safety.
2. Inspect the Drain Hose: Check for kinks or clogs in the drain hose. Straighten any kinks and remove any visible blockages.
3. Access the Drain Pump: The drain pump is usually located at the bottom front or rear of the washer. Consult your owner’s manual for specific location. You may need to remove an access panel.
4. Clean the Drain Pump Filter: Carefully remove the drain pump filter (be prepared for some water to spill). Clean out any lint, hair, or debris.
5. Inspect the Drain Pump Impeller: Check if the impeller (the fan-like part inside the pump) spins freely. If it’s stuck or difficult to turn, there may be an obstruction deeper inside.
6. Clear Drain Pump Obstructions: Use pliers to carefully remove any obstructions preventing the impeller from spinning.
7. Check Water Inlet Valves: Locate the water inlet valves (where the water hoses connect to the washer). Disconnect the hoses and check the screens for sediment buildup. Clean the screens if necessary.
8. Inspect the Drive Motor (if accessible): If you can access the drive motor (usually located under the washer), visually inspect it for any signs of damage or wear.
9. Check the Belt (if applicable): If your washer has a belt, check its condition. Look for cracks, fraying, or looseness.
10. Inspect the Suspension Rods: Open the washer lid and manually push down on the tub. It should bounce back smoothly. If it wobbles excessively or makes noise, the suspension rods might be worn.
11. Reassemble and Test: Reassemble the components you disassembled. Plug the washer back in and run a short test cycle to see if the humming sound is gone.
12. Listen Carefully: Pay close attention to when the humming occurs during the cycle (fill, wash, drain, spin) to help pinpoint the source of the problem.
13. Check for Error Codes: If your washer has a display panel, check for any error codes that might provide more information about the issue. Consult your owner’s manual for a list of error codes and their meanings.

Fix the Issue Without Buying Parts

Sometimes, the humming sound can be resolved without purchasing new parts:

• Reset the Washer: Unplug the washer for 1-2 minutes, then plug it back in. This can sometimes reset the electronic controls and resolve minor glitches.
• Clean the Washer: Run a cleaning cycle with a washer cleaner to remove buildup and debris that might be contributing to the noise.
• Recalibrate the Washer: Some washers have a recalibration cycle. Consult your owner’s manual for instructions on how to recalibrate your machine.
• Inspect for Loose Items: Ensure nothing is leaning against the washer that could vibrate and cause a humming sound.
• Level the Washer: Use a level to ensure the washer is sitting level on the floor. Adjust the leveling feet if necessary. Unevenness can cause vibrations and noise.

When Replacement Might Be Necessary

If you’ve tried the troubleshooting steps above and the humming sound persists, you might need to consider replacing a part. Common parts that fail and cause humming include the drain pump motor ($50-$150 USD), the drive motor ($100-$300 USD), or the bearings ($30-$80 USD, but often require professional installation). If the cost of repairs is significant compared to the price of a new washer, it might be more economical to replace the entire machine.

Safety Warning

• Always unplug the washing machine from the power outlet before performing any maintenance or repairs.
• Be careful when handling water and electrical components to avoid electric shock.
• If you are not comfortable working with electrical appliances, consult a qualified technician.
• Clean up any spilled water immediately to prevent slips and falls.
• Turn off the water supply to the washing machine before disconnecting any hoses.

Tools You May Need

• Screwdrivers (Phillips and flathead)
• Pliers
• Adjustable wrench
• Multimeter (for testing electrical components – advanced)
• Shop towels
• Bucket
• Level
