In one paragraph
The useful diagnostic here is when the noise happens rather than what it sounds like. Noise only at high spin, noise at every rotation, and noise only when the drum is loaded each point at a different component, and the ranking below follows that split. On a Aviva washer the order below is what makes this page worth reading — the causes are ranked for this kind of machine, not listed alphabetically.
What owners actually report
- A rumble or roar that builds as the spin speeds up — The classic drum-bearing signature. It is quiet on a wash and unmistakable at the top of a spin.
- A repeated knock or tap once per drum revolution — Something is attached to or trapped in the rotating assembly — a lifter screw, a coin behind a baffle, or a loose counterweight bolt.
- A squeal or chirp that changes with load — Belt or pulley territory on a belt-driven machine, and a drive-bearing symptom on a direct-drive one.
- Banging and cabinet movement at the start of the spin — Almost always balance rather than damage: the load has gathered on one side and the suspension cannot absorb it.
- NEAR MISS — grinding with no drum movement at all — That is a drive or motor fault, not a noise complaint, and the machine should be stopped rather than diagnosed by ear.
The ranking that matters
- Load imbalance and levelling — Ranked first because it accounts for more noise complaints than every mechanical fault put together, and because it costs nothing to test. Small-cabinet machines are especially sensitive: less mass means less inertia to absorb an off-centre load.
- Foreign objects in the drum or the sump — Second. Coins, wires and clips work past the drum seal and then rattle against the outer tub. The tell is a noise that changes when you rotate the drum by hand with the machine off.
- Drum bearing wear — Third, and it is the expensive one. It ranks here rather than first because it develops over months and it announces itself with a spin-speed-dependent roar that nothing else imitates.
- Drive belt, pulley or motor mount — Fourth. Belts glaze and slip rather than break, so they squeal under load and go quiet when the drum is empty — a pattern that is easy to confirm.
The diagnostic order
- Rock the cabinet corner to corner with the machine off — Any rock at all is a levelling fault, and levelling is the first fix because it changes the loading on everything else.
- Spin the empty drum by hand and listen — A gritty or rough rotation you can hear without the motor running is a bearing answer. Silence here moves you to the balance and belt causes.
- Run a spin with the drum empty — Empty removes the balance variable entirely. If the noise is still there, it is mechanical; if it is not, it is the load.
The owner-side checks
- Level the machine on all four feet — Adjust until it does not rock at any corner and lock the feet. Do this before anything else — half of noise complaints stop here.
Tools: adjustable wrench, spirit levelAbout 20 min
- Check the transit bolts are out — On a recently moved machine, shipping bolts left in the back produce a violent, expensive-sounding noise. It is the cheapest fix there is.
Tools: wrenchAbout 10 min
- Rotate the drum slowly by hand and feel for roughness — With the machine off and the door open, turn the drum a full revolution. Grinding, notches or side-to-side play are bearing findings.
About 10 min
- Clear the filter and inspect the gasket fold for debris — Coins collect in the fold of a front-loader gasket and in the pump filter, and both are reachable with the machine closed.
Tools: shallow trayAbout 20 min
- STOP before splitting the tub — A bearing replacement means dismantling the outer tub or replacing it whole. That is a workshop job, not an owner job.
The safety boundary on this repair
Safety
Water and mains voltage share a small cabinet in this machine, so the breaker goes off before a panel comes off and stays off while your hands are inside. Shut the supply tap as well before undoing any hose. Leave the door interlock alone — it is what stops the drum turning or the heater firing with the door open.
Where owner work ends
Call when the drum feels rough or has play at the rim by hand, because that is a bearing verdict and it does not improve. Call sooner if the noise arrived suddenly rather than gradually — a sudden change points at something broken or trapped, and running the machine on it drives the object into the outer tub where it can hole the plastic and turn a rattle into a leak.
The rest of this family
Where this page stops
Treat this as the generalized Aviva washer page. It is written to be true across the platform, which means it stops short of the details that only hold for one family — connector pinouts, specific board revisions, the order the cabinet comes apart in. Those live on the family- and model-level pages linked here, and where one exists for your unit, that page outranks this one.
