Why washers walk (centrifugal force isn't the villain — the center of gravity is)
At 1,000+ RPM during spin, even a slightly off-center load gets magnified into a pile driver. Front-loaders spin faster than top-loaders — which is why they're the ones that walk. But the designers planned for this: suspension absorbs the wobble, leveling feet flatten the foundation. Violent shaking means one of those three defenses has failed.
Match the evidence
- Jumps only with a single bulky item (comforter, rug, jeans) → Unbalanced load: the comforter flings to one side and the drum punches drunk. Pause, redistribute, add two towels as counterweight, low spin for bulky loads.
- Shakes every spin, whatever's inside → Out of level: push the four corners — one rocking corner is it. Bubble level on top (a phone app works), turn the feet, and tighten the lock nuts — unlocked, the fix lasts two weeks.
- Brand-new machine, or first spin after a move → Shipping bolts: the 3–4 big bolts on the back panel lock the drum for transport — it's supposed to float on its suspension. Pull them and the shaking vanishes. Keep the bolts; the next move needs them.
One honest limit: level, balanced, bolts out — still shaking? That's mechanical: worn shock absorbers (front-loaders; replace in pairs) or suspension springs (top-loaders). A rumble that's grown louder over weeks points to drum bearings — a big repair, but far cheaper than a new machine. Old wooden floors amplify everything: anti-vibration pads help, the floor itself belongs to a contractor.
Before you start. This is a simulation, not your machine. Turning the feet means tilting the washer — power off first. And don't sit on this one: a walking machine yanks its water hoses every spin, and a pulled-loose inlet costs more than any noise.
