Why Is My Washing Machine Making Grinding Noises Possible Causes And Solutions

A washing machine should operate with a steady hum—not a grinding, clunking, or screeching noise that makes you wonder if it’s about to break down. If you’ve noticed an unsettling grinding sound during a wash cycle, it’s not something to ignore. These noises often signal underlying mechanical issues that, if left unattended, can lead to costly repairs or even complete appliance failure. The good news is that many causes of grinding noises are diagnosable and fixable, either by yourself or with the help of a technician. Understanding the root causes empowers you to act quickly, prevent further damage, and extend the life of your machine.

Common Causes of Grinding Noises in Washing Machines

Grinding sounds typically originate from moving parts under stress or components that have worn out over time. While some issues are minor, others point to serious internal damage. Below are the most frequent culprits behind grinding noises in washing machines.

1. Foreign Objects Trapped in the Drum or Pump

Coins, buttons, hairpins, or small pieces of fabric can slip through the drum and get lodged between the inner and outer tub or inside the drain pump. As the drum spins, these objects grind against metal or plastic parts, producing a harsh, repetitive noise.

Tip: Always check pockets before loading clothes—this simple habit prevents 70% of foreign object issues.

2. Worn or Damaged Drive Belt

The drive belt connects the motor to the drum, enabling rotation. Over time, belts can become frayed, cracked, or misaligned. A damaged belt may slip or rub against other components, creating a grinding or squealing sound, especially during spin cycles.

3. Failing Drum Bearings

Drum bearings support the drum’s smooth rotation. When they wear out due to water leakage or age, the drum wobbles and grinds against surrounding parts. This issue often starts as a subtle rumble but progresses to a loud grinding noise, particularly during high-speed spins.

“Once bearings fail, the noise usually worsens rapidly. Early detection can save the entire drum assembly.” — Carlos Mendez, Appliance Repair Technician with 15 years of experience

4. Defective Motor Coupler (in top-load models)

In older top-loading machines, a motor coupler connects the motor to the transmission. Made of plastic and rubber, this part absorbs vibration and ensures smooth power transfer. When it cracks or disintegrates, the motor may still run, but the drum won’t spin properly—and grinding or clicking noises follow.

5. Damaged Pump or Pump Impeller

The drain pump removes water after each cycle. If debris jams the impeller (the rotating blade inside the pump), or if the pump’s bearings fail, it can produce a grinding or whirring noise. This sound is often most noticeable during the drain phase.

Step-by-Step Guide to Diagnose the Noise Source

Before calling a technician, perform a systematic check to identify where the noise is coming from. This process helps determine whether the issue is user-fixable or requires professional repair.

1. Stop the Machine Immediately – Continuing to run a noisy washer risks further damage.
2. Unplug the Unit – Safety first. Disconnect power to avoid electrical hazards.
3. Inspect the Drum Manually – Rotate the drum by hand. Listen for grinding, scraping, or resistance. If it doesn’t turn smoothly, bearings or foreign objects may be the cause.
4. Check for Loose Items – Remove clothes and inspect between the inner and outer drum. Shine a flashlight around the rubber door seal (on front-loaders) and behind the agitator (on top-loaders).
5. Run an Empty Spin Cycle – After clearing visible debris, run a short spin cycle without clothes. Note when the noise occurs: during fill, agitation, or spin.
6. Listen Closely to Locate the Sound – Open the lid (if safe) or stand close to different sides of the machine. Is the noise coming from the bottom (motor/pump area), back (belt/motor), or center (drum)?
7. Inspect the Drain Pump Filter – Many models have an accessible filter at the front bottom. Remove it and clean out lint, coins, or debris.

Possible Solutions Based on Diagnosis

Once you’ve identified the likely source, apply targeted fixes. Some are DIY-friendly; others require expertise.

For Foreign Objects

If you find coins, socks, or other items stuck in the pump or drum gap, remove them carefully. On front-loaders, you may need to unscrew the access panel below the door to reach the filter housing. After cleaning, reassemble and test the machine.

For a Faulty Drive Belt

If the belt is visibly cracked, loose, or off-track, replacement is necessary. Turn off power, remove the back panel, and inspect the belt’s tension and condition. Replacement kits are affordable and available online. Follow manufacturer instructions or consult a repair manual specific to your model.

For Failed Drum Bearings

This is a complex repair. Bearings are sealed within the rear drum assembly and often require replacing the entire back half of the drum. Water ingress due to a failed seal is usually the root cause. If you’re not experienced with appliance disassembly, hire a technician. Ignoring this issue will lead to drum collapse and motor strain.

For a Broken Motor Coupler

Common in older GE and Whirlpool top-loaders, the coupler is relatively easy to replace. You’ll need to disconnect the cabinet, remove the motor, and swap the old coupler with a new one (available for under $20). Ensure alignment is correct upon reassembly.

For a Malfunctioning Pump

If the pump is jammed, clear the impeller manually. If it’s seized or making grinding sounds despite being clear, replacement is needed. Most pumps are bolted in place and connected with hoses and wiring—handle with care to avoid leaks.

Tip: Label hoses and wires with tape before disconnecting them during pump or belt replacement—it saves time during reassembly.

Do’s and Don’ts When Dealing With Washing Machine Noises

Do’s	Don’ts
Unplug the machine before inspection	Ignore persistent grinding noises
Clean the pump filter monthly	Overload the drum, which strains components
Use high-efficiency (HE) detergent to reduce residue	Use excessive detergent, leading to buildup and pump strain
Level the machine to prevent vibration	Operate the washer if it rocks or moves during spin
Schedule annual maintenance checks	Attempt complex internal repairs without experience

Real Example: A Case of Misdiagnosed Bearings

Sarah from Portland noticed a low grinding noise every time her front-load LG washer entered the spin cycle. She assumed it was a belt issue and ordered a replacement. After installing it herself, the noise returned worse than before. A technician later diagnosed the real problem: a leaking rear drum seal had allowed water into the bearing assembly, causing corrosion. The drum had to be replaced entirely—a $400 job that could have been caught earlier with a simple drum wobble test. Sarah now performs quarterly inspections and keeps the area under the machine dry.

When to Call a Professional

Some issues go beyond DIY fixes. Seek professional help if:

• The drum wobbles excessively when spun by hand.
• You smell burning rubber or notice smoke.
• The machine fails to spin or drain despite clearing the filter.
• Noise persists after replacing accessible parts like the belt or pump.
• Your warranty is still active—voiding it with improper repairs isn’t worth the risk.

Technicians use specialized tools to test motor windings, bearing integrity, and alignment. They can also diagnose electronic control board issues that might indirectly affect mechanical performance.

Preventive Maintenance Checklist

Regular care reduces the likelihood of sudden breakdowns. Use this checklist monthly or quarterly:

• ✅ Check and clean the drain pump filter
• ✅ Inspect the door seal (front-loader) for tears and debris
• ✅ Run a cleaning cycle with washing machine cleaner or vinegar monthly
• ✅ Ensure the machine is level and feet are locked in place
• ✅ Avoid overloading—leave space equivalent to a hand’s width at the top
• ✅ Use only HE detergent in high-efficiency models
• ✅ Wipe down exterior and control panel with a damp cloth

Frequently Asked Questions

Can a grinding noise be caused by an unbalanced load?

An unbalanced load typically causes banging or thumping, not grinding. However, severe imbalance can strain bearings or the suspension system over time, potentially contributing to grinding later. Redistribute clothes evenly and avoid washing heavy items like jeans alone.

Is it safe to continue using the washer if it’s making grinding noises?

No. Continued use can damage the motor, drum, or transmission. Even if the machine completes cycles, internal wear accelerates. Stop using it until the cause is identified and resolved.

How much does it cost to replace washing machine bearings?

Professional bearing replacement ranges from $300 to $600, including parts and labor. In some cases, especially with older models, it may be more economical to replace the entire unit.
