Washing Machine Making Buzzing Noise When Spinning

Introduction

A buzzing noise from your washing machine during the spin cycle can be alarming. It usually indicates something is interfering with the normal operation of the motor or the drum. Ignoring this noise can lead to further damage, potentially causing the machine to stop working altogether. Identifying and addressing the issue quickly can save you money and prevent a major appliance breakdown. This guide will walk you through the common causes and troubleshooting steps in plain language.

Common Causes of Washing Machine Making Buzzing Noise When Spinning

Here are some of the most frequent reasons for a buzzing sound during the spin cycle:

Loose Objects: Small items like coins, buttons, or paper clips can get lodged between the inner drum and outer tub, creating a buzzing or rattling sound.
Worn Drive Belt: The drive belt connects the motor to the drum. If it’s worn, cracked, or loose, it can slip and buzz.
Motor Issues: A failing motor, particularly the motor bearings, can produce a buzzing or humming noise.
Pump Problems: The drain pump might be struggling to remove water, leading to a buzzing sound, especially if it’s clogged.
Foreign Object in Pump: Small objects can get lodged in the drain pump, causing it to buzz when it tries to operate.
Worn Drum Bearings: Worn bearings can cause the drum to wobble and create a buzzing or grinding noise during the high-speed spin.
Unbalanced Load: An unevenly distributed load can cause the machine to vibrate excessively and produce a buzzing sound.
Shipping Bolts: If you’ve recently moved or had your machine serviced, ensure the shipping bolts (designed to stabilize the drum during transport) have been removed.
Loose Connections: Loose wiring or connections in the motor or control panel can sometimes vibrate and create a buzzing sound.

Symptoms Checklist

Use this checklist to help pinpoint the problem:

Buzzing noise only during the spin cycle.
Buzzing noise accompanied by vibration or shaking.
Noise louder than usual during operation.
Water not draining properly.
Visible objects stuck in the drum or drain hose.
Machine recently moved or serviced.
Noise changes with different load sizes.

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

Unplug the Washing Machine: Disconnect the power cord from the outlet for safety.
Check for Loose Objects in the Drum: Visually inspect the inside of the drum. Remove any visible items.
Inspect the Rubber Seal: Examine the rubber seal around the door for trapped items.
Check the Drain Hose: Disconnect the drain hose from the back of the machine. Check for clogs or obstructions.
Clean the Drain Pump Filter: Locate the drain pump filter (usually at the bottom front of the machine behind a small access panel). Open the panel, drain any remaining water (have a towel ready), and remove and clean the filter. Remove any debris, coins, or lint.
Check for Shipping Bolts: If you recently moved the machine, check the back for any remaining shipping bolts. Remove them if present.
Level the Washing Machine: Use a level to ensure the machine is sitting level. Adjust the leveling feet at the bottom of the machine until it’s stable and doesn’t wobble.
Run an Empty Cycle: Run an empty cycle on the lowest water level setting to flush out any remaining debris.
Check the Drive Belt (Advanced): If you’re comfortable, proceed with caution: Unplug the machine. Access the drive belt (usually by removing the back panel). Inspect the belt for cracks or wear. A loose or damaged belt can cause buzzing.
Listen Carefully During Spin: Run a small load and listen closely to where the noise is coming from. This can help pinpoint the source (motor, pump, etc.).
Avoid Overloading: Make sure you’re not overloading the washing machine. Overloading can strain the motor and cause excessive vibration.
Distribute the Load Evenly: Ensure the laundry is distributed evenly inside the drum to prevent unbalanced loads.
Check Water Inlet Valves: Sometimes, buzzing can come from partially blocked water inlet valves. Turn off the water supply and inspect the inlet screens for debris.

Fix the Issue Without Buying Parts

Before considering replacements, try these free fixes:

Reset the Machine: Unplug the washing machine for 10 minutes, then plug it back in. This can sometimes reset the control board and resolve minor issues.
Cleaning Cycles: Run a washing machine cleaner cycle with an appropriate cleaner (following the manufacturer’s instructions).
Visual Inspections: Regularly inspect the machine for loose hoses, debris, or signs of wear.
Proper Loading: Always load the machine correctly to prevent imbalances.

When Replacement Might Be Necessary

If the buzzing persists after trying the troubleshooting steps, or if you identify a severely damaged drive belt or motor, replacement of a part may be needed. Motor replacements can range from $100-$300 USD. Pump replacements are usually between $50-$150 USD. Replacing drum bearings is more complex and can cost $200-$400 USD (including labor if you hire a technician). However, sometimes the repair cost exceeds the value of an old appliance, and replacement of the entire machine might be the most economical option. Parts commonly failing and causing buzzing include drain pump, motor, drive belt, and drum bearings.

Safety Warning

Always unplug the washing machine before attempting any repairs.
Avoid working on the machine if the floor is wet to prevent electric shock.
Be careful when handling tools to avoid injury.
If you are uncomfortable performing any of the steps, consult a qualified appliance repair technician.
