Whirlpool Washer Banging Noise

Introduction

A loud banging noise coming from your Whirlpool washer is a common yet concerning problem. This usually indicates something is wrong with the washer’s operation and, if left unaddressed, can lead to further damage and costly repairs. You might hear the banging during the spin cycle, wash cycle, or even when the washer is just filling with water. It’s essential to address this issue promptly because prolonged banging can weaken the machine’s components, reduce its lifespan, and even damage your laundry room floor.

Common Causes of Whirlpool Washer Banging Noise

Several factors can contribute to a banging noise in your Whirlpool washer. Here are some of the most common:

Unbalanced Load: Clothes clumped together on one side of the drum create an uneven distribution of weight.
Overloaded Washer: Putting too many clothes in the washer can strain the motor and suspension system, leading to banging.
Items Stuck in Drum: Small objects like coins, buttons, or socks can get trapped between the inner drum and the outer tub.
Worn Drum Support Springs/Rods: These springs or rods help stabilize the drum during operation. Wear and tear can cause them to weaken.
Failed Snubber/Damper: Located at the bottom of the washer, these parts dampen vibration. A failed snubber can cause violent shaking and banging.
Loose or Damaged Drive Pulley: The drive pulley connects the motor to the drum. If it’s loose or damaged, it can cause noise and vibration.
Worn or Damaged Motor Coupling: This part connects the motor to the transmission. If it’s broken, it can cause banging and other noises.
Foreign Object in Pump: A small object lodged in the drain pump can cause it to vibrate excessively and create a banging sound.

Symptoms Checklist

Use this checklist to accurately identify the cause of the banging noise:

Banging primarily occurs during the spin cycle.
Banging is more pronounced with larger loads.
The washer shakes violently during operation.
You hear a rattling noise along with the banging.
The banging started after washing a bulky item like a blanket or comforter.
The washer is not level on the floor.
You notice excessive vibration even when the washer is empty.

How to Fix Whirlpool Washer Banging Noise Step-by-Step Guide

Unplug the Washer: Always disconnect the power cord from the outlet before starting any repairs.
Check for Overloading: Avoid overloading the washer. Refer to your washer’s manual for the recommended load size.
Redistribute the Load: If the load is unbalanced, stop the washer, manually redistribute the clothes evenly around the drum, and restart the cycle.
Inspect the Drum for Obstructions: Carefully feel around the inside of the drum for any trapped objects like coins, buttons, or socks. Remove any obstructions.
Check the Washer’s Level: Use a level to ensure the washer is sitting level on the floor. Adjust the leveling feet at the bottom of the washer until it’s level.
Inspect the Drum Support Springs/Rods: Open the washer and manually push down on the drum. It should bounce back smoothly. If it wobbles excessively or feels loose, the suspension springs/rods might be worn. This typically requires removing the cabinet for inspection.
Locate and Inspect the Snubber/Damper: Accessing this typically involves tipping the washer back or removing a panel. Visually inspect for damage or wear.
Check the Drive Pulley: Locate the drive pulley at the bottom of the washer, usually behind an access panel. Make sure it’s securely tightened and not damaged.
Inspect the Motor Coupling: This part is located between the motor and the transmission. Look for signs of cracking or breakage. You might need to remove the motor to get a good view.
Clean the Drain Pump: Locate the drain pump (usually at the bottom front of the washer) and carefully remove any debris or obstructions.
Run an Empty Cycle: After inspecting and cleaning, run an empty wash cycle to see if the banging noise persists.
Listen Carefully: Pay close attention to when the noise occurs during the cycle (fill, wash, spin) as this can help narrow down the problem.

Fix the Issue Without Buying Parts

Before considering replacement parts, try these free troubleshooting methods:

Reset the Washer: Unplug the washer for 1-2 minutes, then plug it back in. This can sometimes reset the control board and resolve minor issues.
Clean the Washer Regularly: Run a cleaning cycle with a washing machine cleaner every month to prevent buildup of detergent and debris.
Calibrate the Washer (If Applicable): Some Whirlpool washers have a calibration cycle. Refer to your owner’s manual for instructions on how to calibrate your specific model.
Inspect Hoses: Check the water inlet and drain hoses for kinks or obstructions that might restrict water flow and cause the washer to vibrate.

When Replacement Might Be Necessary

If the banging noise persists after trying the above steps, a worn or damaged component might need replacement. Common culprits include:

Drum Support Springs/Rods: $30 – $80 (set of four)
Snubber/Damper: $20 – $50
Motor Coupling: $15 – $30
Drive Pulley: $30 – $60

Replacing these parts usually involves removing the washer’s cabinet and accessing the internal components. If you’re uncomfortable with this level of repair, it’s best to consult a qualified appliance technician.

Safety Warning

Always unplug the washer from the power outlet before performing any repairs.
Be careful when tipping the washer back to access the bottom components. Have someone assist you to prevent injury.
If you’re working with water, be sure to wear rubber gloves and protect the surrounding area to prevent slips and falls.
If you’re unsure about any step in the repair process, consult a qualified appliance technician.

FAQ

Q: My washer only bangs during the spin cycle. What’s likely the cause?A: This usually indicates an unbalanced load or worn drum support springs/rods.

Q: How do I know if the load is unbalanced?A: If the washer shakes violently during the spin cycle, the load is likely unbalanced. Stop the cycle and redistribute the clothes evenly.

Q: My washer is new, but it still makes a banging noise. What could be wrong?A: Even new washers can have issues. Make sure the shipping bolts (if any) have been removed, and that the washer is properly leveled.

Q: Can I use WD-40 on the drum support springs to reduce the noise?A: No, WD-40 is not a suitable lubricant for drum support springs. It can actually attract dirt and grime and worsen the problem. If lubrication is needed, use a silicone-based lubricant sparingly.
