The short answer
A Commercial Care MAR washer that walks across the floor is usually reporting how it is loaded and how it stands, not a broken part. Portable models get moved between washes, which means the feet and the floor change with every use. Work the free checks before opening anything: load, level, feet, floor.
The observable signs on this platform
- Chirping when the drum turns — Squealing points at a belt or a pulley on belt-driven models.
- A rough sound at low speed — Coins, clips and underwires pass into the gap and grind there.
- Noise that tracks the speed — Spin the drum by hand: a good bearing turns silently.
- New noise since it changed rooms — Re-level from scratch in the new position and check the floor.
- Noise during the drain step only — A hard object in the filter chamber or the impeller rattles only when the pump runs, which is stage-diagnostic.
- NEAR MISS — no spin rather than a noisy one — No spin at all is a drainage or a cycle fault, not a noise complaint.
What it usually turns out to be, in order
- A single heavy item out of balance — First on this family because a compact drum is thrown by one towel of any size of washer.
- Feet unlocked — It ranks here because it is a two-minute job and it magnifies every other cause on this list.
- The tub hitting its travel limits — On compact machines the suspension is lightly built, so it wears within the life of the machine.
- A coin or underwire grinding — Common wherever pockets go unchecked, which makes it routine rather than exotic.
- Drum bearing rough — Last, and it is the expensive one: a bearing announces itself for months before it fails.
Check in this order, and why
- Open the door, spread the washing, spin again — Watch for a towel or a mat that has gathered on one side.
- Set the feet and tighten the lock nuts — Second or third because it is free and it underpins everything else.
- Confirm the transit hardware is out — A bolted tub is rigid, which is what makes the noise so violent.
- Test the floor for spring — A rubber mat on tile or a board on timber is often the whole fix.
- Turn the drum by hand with the machine isolated — Listen for the same sound you hear in use: a match confirms it.
Before you open anything
Safety
Fit the blanking plugs after removal so nothing enters the holes. Leave the door or lid interlock as it is: that switch keeps the drum still. A machine that is walking can pull its hoses tight or unplug itself — do not let it run across the floor.

When this stops being a DIY job
A grinding noise that came with a bang should stop the machine now. A belt or a damper is a modest job by comparison, and worth doing.
