Why is my washer vibrating or shaking? Causes and fixes
A washer that vibrates or shakes violently is most often caused by an unbalanced load, unlevel leveling feet, worn shock absorbers on front-load models, or stretched suspension rods on top-load models. New washers shake when shipping bolts were never removed. Rule out the load and the feet first - they cost nothing to fix - then inspect the suspension. Identify your washer’s model number to order the correct replacement parts.

Safety information
Unplug the washer before removing any panel or inspecting the suspension. When tipping or walking the machine, work with a helper - washers are top-heavy, and suspended tubs can shift unexpectedly. Never run the washer with panels removed to observe the shaking.
Most common causes
- Unbalanced load — heavy items like towels or jeans bunched on one side throw the drum off balance during spin; the most common cause and not a fault.
- Unlevel machine — a washer rocking on its feet amplifies every vibration into cabinet banging and floor shake.
- Worn shock absorbers — the dampers on front-load washers lose resistance with age and let the tub slam during spin.
- Stretched suspension rods — the four rods that hang a top-load tub wear at their ball cups and stop absorbing motion.
- Shipping bolts never removed — new front-loaders ship with bolts locking the tub; running with them in causes violent shaking and damage.
- Failing tub bearing or damaged spider arm — advanced wear lets the drum orbit off-center, usually with a loud roar during spin.
Step-by-step diagnosis
- Rebalance the load and rerun the spin. Redistribute heavy items evenly around the drum, avoid washing a single heavy item alone, and see if the shaking stops. Pair a heavy item with towels to keep the drum balanced.
- Level the machine. Rock the washer by its corners; if it moves, adjust the leveling feet until all four sit solid, then tighten the lock nuts. Check level front-to-back and side-to-side with a bubble level on the cabinet top.
- Check for shipping bolts on newer machines. If the washer has shaken since installation, look at the rear panel for three to four large bolts locking the tub and remove them per the installation guide - running with them in will destroy the suspension.
- Test with an empty spin. Run a spin-only cycle with nothing in the drum. Violent movement with an empty drum clears the load as the cause and points at the suspension, shocks, or bearings.
- Inspect the shock absorbers on front-load washers. Unplug the machine, remove the front or rear panel, and check each shock: it should compress with firm, even resistance and show no leaked fluid or loose mounting pins. Replace shocks in complete sets.
- Inspect the suspension rods on top-load washers. Look for a tub that sags to one corner, bounces repeatedly when pressed down, or bangs the cabinet on spin - all signs the rod ball cups are worn. Replace all four rods as a set.
- Check the tub bearing and spider arm last. Spin the empty drum by hand and lift its edge - grinding, rumbling, or visible play indicates bearing wear letting the drum run off-center. Bearing repairs are involved; weigh cost against machine age.
Replacement parts to consider
Common parts for a shaking washer: shock absorber set, suspension rod kit, leveling feet, tub bearing kit, counterweight bolts, shipping bolt removal is a no-part fix. Enter your washer’s model number on reliableparts.com for the exact parts for your specific model.
Related FAQs
Why does my washer shake violently on the spin cycle?
Violent spin-cycle shaking is usually an unbalanced load or a worn suspension. Rebalance the load and level the feet first. If an empty spin still shakes the cabinet, the shock absorbers (front-load) or suspension rods (top-load) have worn out and should be replaced as a set.
Can a shaking washer damage my floor or the machine?
Yes. Sustained violent vibration loosens internal fasteners, wears the suspension faster, can crack the outer tub or spider arm, and walks the machine into hoses and walls. It also transmits into the floor structure. Treat persistent shaking as a repair item, not a quirk.
Why does my new washer shake so much?
A brand-new front-load washer that shakes violently almost always still has its shipping bolts installed. The bolts lock the tub rigid for transport and must come out before the first cycle - check the rear panel. Also confirm the feet are leveled and locked; installers sometimes skip it.
How much does it cost to fix a shaking washing machine?
The common fixes are inexpensive: suspension rod kits typically run $30-80 and shock absorber sets $20- 60, both DIY-friendly repairs. Leveling and load habits cost nothing. The expensive scenario is a worn bearing or spider arm, which often runs $200-400 professionally.
Do washer anti-vibration pads work?
Anti-vibration pads help with noise transmission into the floor and minor movement, especially on wood-framed floors - but they don’t fix a mechanical cause. If the washer shakes from worn shocks, bad rods, or an unlevel stance, fix that first; then pads are a fine finishing touch.
