# A Washer That Walks: Telling the Load Apart From the Floor

## What causes my Whirlpool washer to shake violently: run this first

Three or four similar towels. Spread them evenly around the basket. Run a spin-only or drain-and-spin cycle. Stand and watch.

That test separates the two problems that arrive as the same sentence, and it costs nothing.

**It spins quietly.** Nothing is wrong with the machine. What you have is a loading habit, and no part will fix it.

**It still walks.** Now it is worth opening the toolbox, and the order below goes from free to expensive.

## Why one heavy item is so much worse than a full load

A washer balances by having enough separate items to redistribute themselves as the basket turns. One dense thing has nothing to balance against. It sits on one side, and the force it produces grows with the square of the spin speed, which is why a load that seemed fine through the wash goes berserk in the last two minutes.

Whirlpool takes this seriously enough to publish a page on it. Under Vibration for its top load washers there is one called Vibration when washing a single item, sitting alongside the general out-of-balance page. The maker's answer and ours are the same: give it company.

A bath mat with a rubber backing is the worst single item in a South Florida laundry closet, because it absorbs water on one face and holds it. Jeans are second. A single pillow floats, which produces its own version of the same problem.

## Level is not the test. Rock is.

People check with a level, find it reads true, and conclude the machine is set up correctly. That is the wrong test.

A washer can read perfectly level and still have one foot barely touching the floor, because a floor is not a plane and a cabinet is stiff. The moment the basket pushes sideways, the machine tips onto three feet and drops back. That is a rock, and it is what produces the banging.

Test it by hand. Press down firmly on two opposite top corners, then on the other two. **Any movement at all is too much.** The correction goes to the foot that lifts: lower it until the rocking stops.

Then lock it. Most feet have a locknut that tightens up against the underside of the cabinet, and a foot that is left free to turn will vibrate itself back out over a few months. A machine that was fine when it was installed and is not fine now is very often exactly this and nothing else.

Rear feet on many top-loaders are self-adjusting: you tilt the machine forward onto its front feet, set it back down, and they find their own height. Doing that after moving a machine is worth thirty seconds.

## The floor is part of the machine

This is the part that gets left out, and in Miami it explains more calls than the suspension does.

A washer standing on a concrete slab is standing on something that will not move. Whatever the machine does, the slab absorbs. The same machine on a wooden platform in a second-floor laundry closet, or on a raised pedestal, is standing on something with its own flex and its own resonance. It does not just transmit the vibration, it can amplify it at particular speeds.

So the same model can be quietly acceptable in a ground-floor townhouse and genuinely alarming in the apartment above. Nothing is wrong with it. It is in a worse place.

Two things help. Shimming the platform so it does not flex under the machine's own weight is the first, and it does more than most people expect. Moving the machine so its feet sit over the platform's joists rather than between them is the second.

## When it is the machine after all

If the load is even, the feet are locked down, the floor is solid and it still walks, the machine has a suspension problem.

On a top-loader that means the suspension rods that hang the tub, which wear and stop damping, and which are replaced as a set of four rather than one at a time. On a front-loader it means the shock absorbers under the drum, replaced in pairs for the same reason. Both are inexpensive stocked parts on this make.

One thing that is not this page: a machine that roars on spin like a jet taking off, rather than banging and moving. That is a bearing, it is a much larger job, and it is worth knowing before anybody starts pricing suspension parts.
