Washers should clean clothes, not shake the entire laundry room. A washer that vibrates too much during spin cycles often points to simple mechanical or setup issues. We’ve seen it happen with both new and old machines. Some fixes are quick and others require a deeper look. If the shaking continues, it may damage the floor, hoses, or even the washer itself. Let’s break down what causes it, how to handle it, and when to consider a service call.
Uneven Washer Feet and Leveling Issues
Most washers vibrate heavily when the machine sits unevenly on the floor. All four feet must touch the ground firmly. One corner even slightly off-balance can create serious motion during high-speed spins. The internal drum spins fast, and when the base isn’t steady, that force travels into the floor and walls.
We always start by adjusting the legs underneath. Twist each foot until the washer sits flat. After that, we push on the corners to check for rocking. If it moves, it still needs leveling. Some floors slope slightly, especially in older basements. In that case, rubber pads help stabilize each foot. Sometimes, even after adjusting, vibration continues. That usually means the issue lies deeper in the unit.

Shipping Bolts Still in Place
Sometimes after installing a new washer, heavy vibration begins right away. That’s often because the shipping bolts are still in place. These bolts hold the drum steady during delivery to prevent damage. If they’re not removed before use, the drum cannot move freely. As a result, all that force goes into shaking the frame.
We always recommend checking the back of the washer if it’s a recent purchase. Four metal bolts, sometimes with plastic sleeves, should be visible and easy to unscrew. Leaving even one bolt installed can cause loud shaking. After removal, washers run much smoother. This step often gets missed during quick installs or when owners move the machine themselves.
Even used washers can have these bolts reinserted during moves. If unsure, a quick peek behind the unit gives clarity. This step takes only five minutes and often fixes vibration immediately.
Load Distribution Inside the Drum
Uneven laundry loads are one of the most common reasons washers shake. When we overload the machine or toss in one heavy item like a rug or blanket, the drum goes out of balance. During spin cycles, that imbalance creates side-to-side motion. The washer compensates by trying to center the load, but sometimes it fails.
To avoid this, we always suggest splitting heavier loads. For instance, two medium towels balance better than one soaked comforter. If the machine stops mid-cycle or resets the spin, it’s likely struggling with balance. Redistributing the load often fixes this. In older top-load models, this problem is even more frequent due to looser drum suspension.
We also suggest avoiding washing one item alone. Instead, add a few smaller items to help distribute weight. It may seem like a small detail, but balance plays a huge role in reducing shake.
Worn Shock Absorbers or Dampers
Front-load washers use shock absorbers to keep the drum steady. These parts wear down over time. When they do, they can’t soften the motion of the spinning drum. As a result, the washer may knock against the cabinet. We check these parts when other causes don’t explain the vibration.
Most machines have two or four shock absorbers near the bottom. They attach to the frame and the tub. If we see broken brackets, oily residue, or loose mounts, the dampers likely need replacement. This isn’t usually a DIY fix unless you’re familiar with disassembly. Worn shocks usually make a deep thumping sound as well as visible shake.
In top-load models, suspension rods play a similar role. When these wear out, the drum may swing or drop too far. Replacing them stabilizes the unit again. Either way, internal parts like these should be inspected if outside causes aren’t the issue.
Weak Flooring or Improper Surface
Another overlooked factor is the surface beneath the washer. If the floor flexes or shifts under the weight of the appliance, vibration increases. In basements, we often see this on thin plywood or worn concrete pads. The force from the spin cycle doesn’t stay inside the washer. It moves the floor, which bounces back and makes shaking worse.
We recommend placing a thick rubber mat beneath the unit. This helps absorb motion and protect flooring. If the area under the washer is soft or unstable, the whole structure needs reinforcement. We’ve also seen issues when machines sit partially on rugs or uneven tiles. A flat, firm surface always reduces shake.
If the washer shakes even after all these adjustments, it may be time for a deeper diagnostic. Our appliance repair in St Albert team handles these situations all the time. Having a professional inspect both the unit and its installation can uncover hidden causes.
Loose Internal Components
Some shaking problems come from inside the washer, especially in older units. Over time, bolts can loosen, or internal mounts wear out. We’ve seen drum assemblies shift from their center. When this happens, even small loads create big motion. Machines may also make clunking or rattling noises during spin.
If nothing changes after adjusting the feet, checking the floor, and balancing loads, this is the next place to look. Removing the back panel shows the drum mounts, motor bracket, and springs. If anything looks off-center or loose, that’s likely the source of the issue.
Unfortunately, not all internal repairs are cost-effective. When parts like the outer tub or drum shaft become worn, replacement costs rise quickly. In those cases, we explain the options clearly and help customers decide what’s best based on age and condition.
Installing Anti-Vibration Pads
After checking for mechanical problems, we often suggest anti-vibration pads. These thick rubber blocks sit under each washer foot and help absorb motion. They’re inexpensive and simple to install. Many homes, especially condos and older houses, benefit from this upgrade.
These pads also help with sound. Vibrations cause washers to hum or rattle against walls and cabinets. By isolating the unit from the floor, the pads reduce both shaking and noise. However, they’re not a substitute for fixing other issues. If the drum is off-balance or the shocks are worn, pads won’t solve the root problem.
We suggest these only after leveling the washer and ensuring everything else checks out. When added correctly, they often help reduce the remaining motion and keep the unit steady during fast spins.
When to Consider Professional Service
If you’ve checked everything and the washer still shakes, it’s time to consider help. Internal part failure, unbalanced drums, or electrical issues can’t always be spotted without removing panels. Ignoring the shake can lead to damage over time. Hoses may loosen, internal wires can rub, or bolts may break from constant motion.
A service technician can test components while the unit runs. This helps find subtle faults that may not show while the washer is off. They also carry tools to remove, adjust, or replace parts safely. Waiting too long can turn a small issue into a full repair.

FAQ
Why does my washer shake only during certain cycles?
Spin cycles create the most force. If vibration only happens then, the problem is likely related to balance, flooring, or drum movement.
Can I fix a vibrating washer myself?
Some issues like leveling feet or adjusting the load are simple fixes. For internal parts or loose drums, it’s better to call a technician.
Is it dangerous to keep using a washer that shakes?
Yes. Continued shaking can damage hoses, floors, and even the washer frame. It’s best to stop and address the issue quickly.
Do anti-vibration pads really help?
Yes, they reduce motion and noise. However, they should be used after leveling and fixing any mechanical problems.
How do I know if the shocks are worn out?
Look for excessive motion during spins, loud banging sounds, or if the drum feels loose when pressed by hand. Worn shocks often cause those symptoms.
