Start here, for SLTW models
Most alarming noises from an Avanti SLTW washer come from foreign objects and installation rather than from failure. A coin in the outer tub rattles on every turn, a machine on three feet walks, and a pump with a button in it grinds. All three are owner-findable.
What the owner sees
- A grinding or gravel noise during drain — Looking at SLTW models specifically, debris in the pump housing or a fouled impeller makes exactly this at the drain step.
- A metallic rattle on every drum rotation — On SLTW models in particular, something has got between the drum and the outer tub — a coin, an underwire, a screw.
- A hum with no drum movement at all — For SLTW models, a motor or a belt that has failed, or a drum jammed by something, which is a different fault.
- The machine moves across the floor during the spin — Looking at SLTW models specifically, a walking machine strains its own hoses and connections, so it is worth fixing promptly.
- A rhythmic squeal that rises with the spin — Where SLTW models are concerned, noise that tracks the spin speed points at something turning rather than at the load.
- NEAR MISS — noise plus water on the floor — A walking machine strains its hoses. Read the water-leak page for your model line, because the leak is the urgent half.
What goes wrong here, most frequent first
- An unbalanced load — It leads because a single heavy item — a towel, a mat, a duvet — puts the drum out of balance and the machine has no way to fix it.
- A coin, wire or button between drum and tub — A rattle on every rotation that grows worse is an object working its way round the outer tub. On the SLTW models below the ranking is the same.
- Worn suspension, dampers or springs — The tub no longer settles, so it knocks the cabinet at every spin and walks even when level.
- A failing drum bearing or a worn belt — It comes last because everything cheaper imitates it, and because bearing work is a major repair on most machines. Nothing in the SLTW line changes that order.
Where to start, and what follows
- Open the door and redistribute the load by hand — On SLTW models, if the spin then runs quietly, the fault was the load and nothing needs repairing.
- Push each top corner and check for rock — Any movement means a foot is off the floor, which is the second commonest cause of the whole fault.
- Feel right round the drum and the seal folds by hand — Where SLTW models are concerned, do it with the machine isolated and turn the drum slowly by hand while you feel.
- Check behind the machine for transit bolts or packing — Look for bolts or plastic blocks at the back and underneath; keep them somewhere in case it moves again.

Safety
Isolate the washer at the plug or the breaker before any access; a capacitor can stay charged after the power is off. These machines are heavy and top-heavy when wet, so empty it before you move it and get help rather than walking it alone. Leave the lid catch and its wiring exactly as built.

Where the owner line falls
The owner half of a noise complaint is the load, loose objects, the transit bolts, the feet and the floor. Beyond that, call — and call sooner rather than later for a bearing, because a bearing left to run takes the drum and the seal with it.
