Why Does a Washing Machine Shake? Troubleshooting Tips

A shaking washing machine can be more than just an annoying rattle—it can mean there’s something wrong with your appliance. From minor issues like unbalanced loads to more serious mechanical problems, there are several reasons your washer might be bouncing around. In this article, we’ll walk through the most common causes, quick DIY checks, and when it’s time to call in a pro.

Is It Normal for a Washing Machine to Shake?

A little vibration during the spin cycle is normal, especially for front-load washers. However, there are some key points to keep in mind:

Normal Vibration: All washers, especially front-load models, will shake a bit due to the high-speed spin cycle. This helps remove excess water from clothes.
Top-Load vs. Front-Load: Front-load washers typically shake more because they spin faster to extract more water, creating stronger centrifugal forces.
Excessive Shaking: If the washer shakes violently, moves across the floor, or makes loud noises, it could indicate an underlying issue.
Damage Risk: If excessive shaking is left unchecked, it could cause wear on the internal components, increase noise, or even damage your floor or the washer itself.

Key Takeaway: Some shaking is normal, but if your washing machine shakes excessively or starts to “walk” across the room, it’s important to troubleshoot the cause before it leads to further damage.

How Come a Washing Machine Shakes So Bad?

If your washing machine shakes violently, here are the most common causes:

Unbalanced Loads: Heavy items (like towels or jeans) clumped on one side can throw off the balance, causing shaking.
Solution: Distribute heavy items evenly or wash them with lighter items.
Shipping Bolts Left in Place: Shipping bolts secure the drum during transport. If left in place, they prevent proper movement.
Solution: Remove shipping bolts before first use (check the manual for instructions).
Uneven Flooring: An uneven or weak floor can amplify vibrations, making the shaking worse.
Solution: Use a level tool to ensure the washer is sitting evenly and adjust the feet if needed.
Overloading: Overstuffing the washer can lead to an imbalance and excessive shaking.
Solution: Avoid overloading the machine, especially with heavy items.
Worn-Out Parts: Components like shock absorbers or suspension springs may wear out over time, causing the washer to shake.
Solution: Inspect parts for wear and replace them if necessary

Key Takeaway: Violent shaking is usually caused by unbalanced loads, uneven flooring, leftover shipping bolts, overloading, or worn parts—most issues can be fixed with simple adjustments or basic maintenance.

How to Quickly Check for an Unbalanced Load

An unbalanced load is one of the easiest and most common issues to fix when your washing machine starts shaking. Here’s how to check and correct it in just a few steps:

Pause the Cycle: As soon as you notice excessive shaking or loud thumping, hit the pause or stop button on your machine.
Open the Door or Lid: Once the drum stops spinning, open the washer and inspect the load.
Rearrange the Clothes: If everything is clumped to one side, redistribute the items more evenly around the drum. To improve equilibrium, try to combine heavy and light objects.
Remove or Add Items: If the load is too small, add a few extra towels or garments to balance things out. If it’s overstuffed, take out some items and run a smaller load.
Restart the Spin Cycle: Securely close the lid or door, then restart the cycle or select a spin-only option to see if the shaking stops.

Key Takeaway: Fixing an unbalanced load is quick—pause, reposition clothes, and restart. Even distribution is key to a smooth, quiet spin cycle.

Can My Flooring Be the Problem?

Yes, your flooring can absolutely contribute to shaking the washing machine. Even if your washer is working perfectly, the surface it sits on plays a big role in how stable it is during operation.

Uneven Floors: If the floor under your washer isn’t level, it can cause the machine to tilt slightly. That small tilt gets amplified during high-speed spins, leading to rocking or walking.
Solution: Use a bubble level to check the floor and adjust the washer’s leveling feet until all corners sit flat and stable.
Weak or Bouncy Floors: In older homes or second-floor laundry setups, the floor might be flexible or weak, which increases vibration and noise.
Solution: If possible, reinforce the flooring or consider relocating the washer to a sturdier surface (like a basement or concrete slab).
Slippery Surfaces: Tile or hardwood floors can allow the washer to “walk” when it shakes too much.
Solution: Install anti-vibration pads or a non-slip mat under the washer to absorb movement and noise.
Improper Installation: Sometimes, the issue isn’t the floor itself but how the washer was installed on it. If it isn’t leveled correctly during setup, shaking will happen.
Solution: Re-check installation instructions and ensure the washer is properly balanced.

Key Takeaway: Your washer is only as stable as the floor it’s on. Level, firm surfaces prevent shaking—use pads or make adjustments if your floor isn’t up to the job.

When Should You Call a Technician?

While many causes of washer shaking can be fixed at home, some problems go beyond a DIY solution. You may avoid more damage to your appliance and save time and money.

The Machine Still Shakes After Troubleshooting: If you’ve rebalanced the load, leveled the machine, and checked the floor—and it still shakes violently—it’s time for professional help. Ongoing issues might signal deeper mechanical problems.
Loud Crashing or Grinding Noises: These noises can indicate worn bearings, a damaged drum, or loose internal components that need expert attention.
Leaking Water During Use: If your washer is shaking and leaking, the movement may have damaged hoses or internal seals. If left unchecked, this may result in mold growth or water damage.
The Washer “Walks” Across the Floor: Minor shifting is one thing, but if your washer is literally moving several inches or more during each spin cycle, there could be a serious imbalance or suspension failure.
Repeated Error Codes or Shutting Off Mid-Cycle: Some modern washers will flash error codes or stop working entirely when something’s wrong. If this happens frequently, it’s best to have a technician diagnose the issue.
Suspicion of Worn Internal Parts: Over time, parts like shock absorbers, suspension rods, and dampening straps wear out. If your machine is older and showing signs of wear, a technician can inspect and replace the necessary components.

Key Takeaway: If your washer keeps shaking after basic fixes—or if it’s noisy, leaking, or shutting off—don’t ignore it. Calling a technician early can prevent costly damage and extend your washer’s life.

Conclusion

Washing machine shaking can range from a quick fix to a mechanical problem needing attention. The good news is that many issues, like unbalanced loads or uneven floors, can be handled with a bit of DIY. When in doubt, though, getting a technician involved could save your washer (and your sanity).

FAQs

How do I know if my washer’s shocks are bad?

If your washer thuds loudly and moves a lot during spinning, the shock absorbers might be worn out.

Why does my washer shake more with small loads?

Smaller loads don’t distribute weight evenly, causing imbalance. Add a towel or two to balance it out.

Are vibration pads really effective?

Yes—especially on tile or hardwood floors. They help absorb motion and reduce noise.

Can overloading a washer cause permanent damage?

Repeated overloading can wear out the suspension system, motor, and bearings prematurely.

Should I install my washer on a pedestal?

Pedestals can amplify vibration if the washer isn’t properly balanced. Only use one if it’s specifically designed for your model.
