Quick answer
Most violent shaking comes from an unbalanced load, a washer that isn't level, or shipping bolts that were never removed from a new machine. If those are fine, worn shock absorbers on a front-loader or worn suspension rods on a top-loader are the usual cause. Stop the washer if it's banging hard, because it can damage itself and the floor.
Some vibration during spin is normal. A washer that jumps, bangs against the wall or walks across the floor is not. Front-loaders spin fast, and any problem with balance or suspension gets amplified at high speed.
The first three causes cost nothing to fix. The rest are worn suspension parts that we can usually replace in one visit.
Causes, from most to least likely
1.Unbalanced load
A single heavy item, like a rug, a waterproof mattress pad or a wet comforter, concentrates weight on one side of the drum. Waterproof items can also trap water and create a lopsided load.
- Check it yourself
- Stop the cycle, redistribute the load, and add towels to balance a single heavy item. Don't wash rubber-backed mats or waterproof items unless the manual allows it.
- The fix
- No repair needed. If small, balanced loads still shake, keep going.
2.Shipping bolts left in
New front-load washers ship with long bolts through the back that lock the tub in place. If they aren't removed, the tub can't move on its suspension and the whole washer shakes hard on the first spin. Machines that were moved, like a stacked unit in a condo sale, sometimes get them reinstalled.
- Check it yourself
- Look at the back panel for bolts with plastic spacers. Most manuals show three or four. If they're still there, the washer was never prepared for use.
- The fix
- Remove the bolts and plug the holes with the caps that came with the washer. Keep the bolts in case you move.
3.Washer not level or on a weak floor
If one foot is off the floor, the washer rocks with every turn. Wood-framed floors, common in second-story laundry rooms and older condos, flex more than slab floors and make vibration worse. Pedestals add height and can magnify movement if they aren't level.
- Check it yourself
- Press down on each corner. Any rocking means a foot needs adjusting. Use a level side to side and front to back, then tighten the lock nuts on each foot.
- The fix
- Leveling and tightening the feet is free. On flexible floors, an anti-vibration pad can help.
4.Worn shock absorbers or dampers (front-loaders)
Front-loaders hang the tub on springs and use two or more shock absorbers underneath to steady it. Over time the dampers lose resistance, and the tub bangs into the cabinet during spin. Heavy daily use, such as in rentals, wears them faster.
- Check it yourself
- With the washer empty and unplugged, push down on the top of the drum through the door. It should move and settle quickly. If it bounces several times or knocks, the shocks are likely worn.
- The fix · typical $190 – $320
- The shock absorbers are replaced in pairs. The springs are replaced if they're stretched or broken.
5.Worn suspension rods or springs (top-loaders)
Top-loaders hang the tub on four suspension rods from the top corners. When the dampers on those rods wear out, the tub swings wide and can trip an off-balance error or knock against the cabinet.
- Check it yourself
- With the washer empty, push the tub to one side and let go. It should swing back and settle. A tub that keeps swinging, or sits lower on one side, points to worn rods.
- The fix · typical $190 – $320
- The suspension rods are replaced as a set of four.
6.Worn tub bearings or broken spider arm
On front-loaders, the drum is held by a metal spider arm on a shaft running through bearings. If the bearings fail or the spider arm cracks from corrosion, the drum wobbles inside the tub. A loud roar or grinding sound usually comes with it.
- Check it yourself
- With the washer unplugged, lift the drum at the front edge. Noticeable play or a clunk means bearing or spider damage.
- The fix
- This is a major repair. On older machines it often costs more than it's worth, and we'll give you an honest call.
7.Loose counterweight
Heavy concrete blocks are bolted to the tub to steady it. If a bolt loosens or the block cracks, it knocks during spin and throws off the balance.
- Check it yourself
- Listen for a loud clunk from inside the cabinet during spin. Confirming it means removing a panel, so leave that part to us.
- The fix
- The counterweight bolts are tightened or replaced.
When to call a technician
Call us if the washer still shakes with a small, balanced load on a level floor with the shipping bolts out, or if you hear a clunk or roar during spin. Shaking left alone can break the cabinet, the door lock or a stacked dryer above it. We serve Clearwater, Dunedin, Largo and the beaches.

Every repair carries a 45-day warranty on the parts we install and on our labor.
What the warranty covers →Common questions
Is it normal for a front-load washer to shake?
+
Some vibration during the high-speed spin is normal. Hard banging, the washer moving across the floor, or loud knocking is not.
Can a shaking washer damage a stacked dryer?
+
Yes. Heavy vibration can loosen the stacking kit and shift the dryer. If you have a stacked pair, address shaking quickly and check that the stacking brackets are secure.
How do I level my washer?
+
Turn the front feet to raise or lower each corner, check with a level, then tighten the lock nuts against the cabinet. Many washers have self-adjusting rear feet that settle when you tilt the washer forward and set it back down.
Why does my washer only shake with certain loads?
+
Heavy single items and waterproof items are hard to balance. If only those loads shake, it's likely the load, not the washer.
Are anti-vibration pads worth it?
+
They can help on flexible wood floors. They don't fix worn shocks or an unbalanced drum, so check those first.
