Why Is My Washing Machine Shaking Violently? 6 Proven Fixes
Why is my washing machine shaking violently was the exact thought running through my head standing in the doorway of my laundry room, watching the entire machine visibly rock and thump against the wall during the spin cycle, loud enough that I genuinely worried it might walk itself across the floor. After looking into it properly, I found this is one of those problems that looks far more dramatic than it usually is, and in most cases, it comes down to something you can fix yourself in under ten minutes.
Here’s what’s actually causing it, in the order you should check.
An Unbalanced Load Is the Most Common Cause
This is, by a wide margin, the number one reason why is my washing machine shaking violently, especially during the spin cycle specifically. When laundry bunches up unevenly on one side of the drum — which happens easily with large items like comforters, towels, or a single heavy jacket — the machine spins with uneven weight distribution, causing significant shaking as it tries to reach full spin speed.
Fix: Pause the cycle, open the machine, and manually redistribute the clothes evenly around the drum. Mixing large and small items together in future loads, rather than washing one bulky item alone, also helps prevent this from happening again.
The Machine Isn’t Level on the Floor
Washing machines need to sit perfectly level to distribute vibration evenly through their adjustable feet. If even one corner is slightly higher or lower than the others, the entire machine rocks with each spin cycle, and this shaking often gets progressively worse over time as the imbalance causes uneven wear.
How to check: Place a level on top of the machine, checking both side-to-side and front-to-back. Most washing machines have adjustable feet that can be manually turned to raise or lower each corner until the machine sits completely flat and stable.
Shipping Bolts Were Never Removed (New Machines Only)
This is a surprisingly common cause with newly installed machines. Washing machines come with transport bolts that lock the drum in place during shipping to prevent damage, and if these aren’t removed during installation, the drum can’t move freely during operation, causing violent shaking and banging noises during every cycle.
Fix: Check your installation manual for the exact bolt locations (usually on the back panel), and remove them completely if this is a newly installed unit still shaking excessively.
Worn Suspension Springs or Shock Absorbers
Front-load washing machines in particular rely on suspension springs or shock absorbers to dampen the drum’s movement during spin cycles. Over years of use, these components wear out and lose their ability to properly cushion the drum’s rotation, resulting in noticeably more shaking than when the machine was newer.
This is a common answer to why is my washing machine shaking violently in units over 6-7 years old, particularly if the shaking has gradually worsened rather than appearing suddenly.
What this looks like: Unlike an unbalanced load (which varies cycle to cycle depending on what you’re washing), worn suspension components cause consistent shaking across nearly every load, even ones that seem properly balanced.
Overloading the Machine Beyond Capacity
Packing too many clothes into a single load restricts the drum’s ability to properly redistribute weight during the spin cycle, similar to an unbalanced load but caused by overall volume rather than uneven placement. Most machines have a recommended capacity clearly stated in the manual, and consistently exceeding it puts extra strain on internal components over time.
If your machine also isn’t draining properly on top of shaking, our guide on washing machine not draining covers that issue separately.
A Damaged or Worn Drum Bearing
If you’ve checked leveling, load balance, and suspension components without success, a worn drum bearing may be the remaining cause. This part allows the drum to rotate smoothly within the machine’s outer frame, and as it wears down, it can introduce noticeable wobble and shaking, often accompanied by a grinding or squeaking sound during the spin cycle.
Reality check: Bearing replacement typically requires significant disassembly of the machine and is usually best handled by a professional technician, since improper reassembly can cause further damage.
Quick Diagnostic Order
- Redistribute the load evenly inside the drum
- Check the machine is sitting level using a spirit level
- For new installations, confirm shipping bolts were removed
- Note whether shaking happens with every load or only unbalanced ones
- Listen for grinding sounds that might point to a worn bearing
- If nothing above helps, suspension components may need professional replacement
Working through this list in order usually resolves why is my washing machine shaking violently without needing a service call at all.
Final Thoughts
A washing machine shaking violently looks alarming, but in most households, it comes down to an unbalanced load or a machine that isn’t sitting level — both free, quick fixes. Newer machines shaking from day one almost always point to forgotten shipping bolts, while gradually worsening shaking in older units usually means suspension components are simply wearing out with age.

FAQs
Q: Is it dangerous if my washing machine shakes violently during spin cycles?
Occasional shaking from an unbalanced load isn’t dangerous, but consistent violent shaking can loosen water connections or damage flooring over time, so it’s worth addressing rather than ignoring.
Q: How do I know if my washing machine’s suspension needs replacing?
If shaking has gradually worsened over several years and happens consistently regardless of load balance, worn suspension components are the most likely cause.
Q: Can overloading really cause a washing machine to shake?
Yes, exceeding the machine’s recommended capacity prevents proper weight redistribution during spinning, leading to noticeably more shaking than a properly sized load.
