Excessive vibration, a machine that “walks” across the floor during spin, or loud banging is most often an unbalanced load or a machine that isn’t sitting level, not a mechanical failure. It’s also one of the fastest problems on this site to rule out yourself, so start with the two checks below before assuming a part has worn out.
This page is part of our full washing machine troubleshooting guide. If shaking is paired with water on the floor, check our leaking guide too, since a machine that shakes hard enough can work a hose connection loose over time.
Quick Diagnosis Table
| Cause | Likelihood | Difficulty | Typical Part Cost |
|---|---|---|---|
| Uneven load distribution | Very likely | Easy (no tools) | $0 |
| Machine not level on the floor | Likely | Easy | $0 |
| Shipping bolts not removed (new installs) | Likely on new installs | Easy | $0 |
| Overloading beyond rated capacity | Possible | Easy | $0 |
| Worn suspension rods or springs (top-load) | Possible | Moderate | $20–50 |
| Worn shock absorbers (front-load) | Possible | Moderate | $25–60 |
| Worn drum bearing | Rare | Professional recommended | $150–250+ |
Repair or Replace?
The most common causes cost nothing to fix. Suspension rods, springs, and shock absorbers are inexpensive parts and a reasonable weekend repair on most machines. A worn drum bearing is the exception: it usually means partially disassembling the outer tub, and on a machine past 8–10 years, the labor alone often costs more than the machine is worth. In that case, replacement is usually the better call.
Suspension design varies the most of any system between brands. Whirlpool, GE, Samsung, LG, Maytag, Kenmore, Electrolux, and Bosch each use different combinations of springs, rods, and dampers depending on top-load or front-load design. Brand-specific versions of this guide are on the way.
If the drum won’t spin at all rather than shaking, that’s a different issue. See our not spinning guide.
Frequently Asked Questions
Is it normal for a washing machine to vibrate a little during spin?
Yes, a small amount of vibration is normal, especially at the start of the spin ramp-up. What's not normal is banging, walking across the floor, or vibration strong enough to rattle nearby items.
I removed the shipping bolts, but the machine still shakes. What now?
Work through the load balance and leveling checks next. Removed shipping bolts fix one specific cause; they don't rule out an uneven load or an unlevel floor, which are just as common.
Can a washing machine on an upper floor shake more than one on a concrete slab?
Yes. Wood-framed floors flex more than a concrete slab, which can make normal vibration feel and sound worse even when the machine itself is working correctly.
How do I know if it's the suspension or the drum bearing?
Suspension problems usually show up as banging or heavy rocking during spin. A bearing problem typically sounds like a grinding or rumbling noise that gets louder as spin speed increases, independent of how balanced the load is.
Will overloading the machine just once cause lasting damage?
A single overloaded cycle is unlikely to cause damage on its own, but doing it regularly accelerates wear on the suspension components and the drive system over time.
