A washing machine reaching full spin is holding a heavy, wet, off-centre load and turning it at over a thousand revolutions a minute. Everything about the machine's design exists to keep that under control. When it gets loud, something in that chain has given up — but it is very often not the expensive thing.
Work through this in order. The first four cost nothing.
1. The shipping bolts (only once, but check it)
Every front-loading washer ships with three or four steel bolts through the back panel that clamp the drum rigid so it cannot move in transit. They must come out before first use.
If your machine is new, or newly moved, and it sounds like someone is hitting it with a hammer from the first spin, look at the back panel. If the bolts are still in, you have found it. Running a machine with them in will eventually destroy the suspension, so stop using it until they are out.
We are called out for this several times a year, usually after a house move.
2. The machine is not level
This is the most common cause of walking by a wide margin.
All four feet must be in firm contact with the floor and the machine must not rock. Push down on each corner in turn. Any movement at all and the feet need adjusting — most have a threaded foot and a lock nut.
A machine that rocks on a diagonal will move across a floor during spin no matter how good its suspension is. On an old timber floor in a triple-decker, which is most of what we see in Somerville and Dorchester, this needs checking once a year.
Then lock the nuts. Feet that vibrate loose put you straight back where you started.
3. The load is unbalanced
One heavy item — a bath mat, a duvet, a single pair of jeans — behaves completely differently from a mixed load. It collects on one side of the drum, and the machine is now spinning a lump rather than a ring.
Modern machines try to sense this and redistribute. When they cannot, they either slow down and take an hour, or they thump.
If the noise only happens with bedding or towels, the machine is fine and the load is the problem. Wash big single items with a couple of smaller ones to break them up.
4. The floor
A washer in an unheated basement on a concrete slab is a different machine from the same model on a first-floor timber deck. If yours is upstairs and the room drums when it spins, the floor is amplifying rather than the machine misbehaving.
Anti-vibration pads under the feet genuinely help here, cost very little, and are worth trying before anything else. They are not a fix for a rocking machine — level it first.
Now the actual faults
If all four of those are clean and it still bangs, the part that has gone is usually one of these.
Worn suspension rods or damper straps. A front loader hangs its drum on rods with friction dampers. They wear. The symptom is a drum that bounces freely when you push it by hand instead of returning slowly, and a knock that appears as the machine accelerates and then settles.
Broken or stretched springs on a top loader, same idea from the other direction.
Drum bearings. This is the expensive one. The sound is distinctive — a rumbling roar that rises with drum speed, like an aircraft taking off, and it is present on spin even with an empty drum. Grab the drum and try to move it up and down; play there confirms it.
On some machines the bearing is a sealed unit with the outer drum, which means the repair costs a serious fraction of a new machine. That is one of the few cases where we will tell you plainly that replacing the appliance is the better decision, and we would rather say it on the phone than after a diagnostic fee.
A foreign object between the inner and outer drum — coins, an underwire, a screw. This is a sharp rattle on spin rather than a rumble, and it is a cheap fix if it is caught before it scores the drum.
The test that separates them
Run a spin cycle with the drum empty.
- Loud when empty → suspension, bearings, or something loose inside.
- Quiet when empty, loud when loaded → balance, levelling, or the load itself.
That single answer is the most useful thing you can give us on the phone.
For anything past the free checks, washer repair is what we do, with the parts that fail most often already on the van. Call (617) 685-8530 and tell us the make, the model, and whether it is loud with an empty drum.
