What this usually turns out to be
A noisy washing machine is diagnosed by when the noise happens. Banging on spin is balance; grinding on spin is a bearing; rattling at any speed is an object; squealing is a belt or a pump.
What the noise sounds like
- A rumbling roar that rises with spin speed — The drum bearing. It gets louder over months and it does not recover.
- A rattle or clatter at the drain stage — Something in the pump or the filter — a coin, a button, a hair grip.
- A grinding as the drum turns slowly — An object trapped between the drum and the outer tub, most often an underwire.
- NEAR MISS — No noise, the machine simply will not spin — That is usually a drainage problem, and the drainage page covers it.
What is behind it, ranked
- An unbalanced load, an unlevel machine or transit bolts — A machine that is not level, or that stands on a springy floor, amplifies all of it. It is first because it costs nothing, and because the parts below it are only worth suspecting once it is cleared.
- Worn suspension, dampers or springs — The drum hangs on springs and dampers that wear, and a worn set lets the drum swing far enough to hit the cabinet on spin.
- Something trapped in the drum, the filter or the tub — Coins and buttons reach the pump and clatter at the drain stage; underwires slip through the drum holes and grind between the drum and the outer tub.
- The drain pump — It is reached at the filter housing on many machines, which makes it one of the more accessible parts.
- The drum bearing — It is worth diagnosing early: a bearing run to destruction can damage the tub and take the machine with it.
Check in this order, and why
- First — level the machine and redistribute the load — Check every foot meets the floor and the cabinet does not rock, then open the door mid-spin and spread the load. If the noise goes, it was balance, and no part is faulty.
- Second — push the drum and watch it settle — With the machine off, push the drum down and let go. A drum that keeps bouncing rather than settling has tired dampers, which explains banging with a balanced load.
- Third — turn the empty drum slowly by hand — With the power off, rotate the drum and listen for a scrape or a click. An underwire between the drum and the tub usually announces itself this way, and a coin in the pump rattles at the filter.
- Fourth — listen specifically at the drain stage — Noise confined to draining, especially with slower emptying, points at the pump or something in it rather than at the drum.
Owner checks, in order
- Check for transit bolts on a newly delivered machine — Look at the back panel for the bolts that lock the drum for transport. Left in, they produce violent noise from the first spin.
Tools: spannerAbout 15 min
- Level the machine on all four feet — Adjust until the cabinet does not rock in any direction and lock the feet. A machine that rocks bangs, walks and sounds broken.
Tools: adjustable wrench, spirit levelAbout 25 min
- Redistribute the load and try again — Open the door, spread the washing evenly and restart the spin. Heavy items clump and a clumped load bangs however healthy the machine is.
About 15 min
- STOP HERE if the noise is a spin rumble or the cabinet has to come apart — Bearings, dampers and anything trapped between the drum and the tub mean the machine comes apart, which is technician work.
Power off before panels come off
Safety
Power off, water off, and let the machine drain before you tip or move it. A washer full of water weighs more than anyone expects and it goes over easily. Do not force a locked door on a front loader while water remains in the drum, and keep hands clear of the drum until it has stopped completely — it coasts long after the cycle ends.
When to call a technician
The owner line is the filter and the feet. Levelling, redistributing, turning the drum by hand and clearing the pump filter are yours; bearings, dampers and the outer tub are not.

What it does not cover is the detail that only holds for one family of models: access routes, panel layouts, the specific part fitted and the small changes in the check order that come from how a particular platform is built. Those belong on the family pages, which are more specific than this one wherever they exist for your model.
