Start here
On the BTL line a new noise is a filter question first, because the sump on the models listed in the table on this page sits directly below the drum and anything that leaves a pocket lands in it. The brand-generic page starts with the load; here the filter comes first because this platform puts it within reach.
What you are seeing
- A hum with no drum movement — A hum without rotation is a drive fault rather than a noise fault.
- A hollow booming at particular speeds — Resonance comes and goes with speed and disappears when the machine is moved a few centimetres. The BTL line behaves the same way here from one model to the next.
- A high-pitched squeal during the wash — A squeal that follows drum rotation rather than spin speed is friction, not bearing wear.
- A rattling or clicking from the pump area — A coin or a button circulating in the sump hits the impeller housing on every rotation of the pump.
- A scraping from inside the drum — Anything metallic through a drum hole makes this sound and will damage clothes before it damages the machine.
- NEAR MISS — the noise is the drain pump running normally — A short whirr at the end of each phase is the pump doing its job and it is not a fault.
- NEAR MISS — the machine is new and still has transit bolts fitted — A brand-new machine that hammers has usually not had its transit bolts removed.
The causes, ranked
- Coins or keys between the drum and the tub — Top of the list here. Anything in the gap is urgent: it damages the machine while it makes noise. What separates the BTL line here is the order, not the parts.
- A motor bearing rather than a drum bearing — Second, and common. Motor noise is constant in pitch and does not rise with the spin, which is what distinguishes it.
- Worn suspension dampers or springs — Next after those two. Damping wears out gradually, so the machine passes balance checks less and less well and eventually knocks on every spin. Owners of the models listed in the table on this page describe this in almost identical words.
- Foreign objects in the sump or the filter — Fourth. The filter catches most of them, which is why cleaning it both cures the noise and proves the cause.
- A worn or slipping drive belt — Fifth. A glazed belt squeals under load and slips at spin-up, so the drum never reaches speed.
Check in this order, and why
- Check every foot for a loose lock nut — Each foot has a nut that locks it against the base; one loose nut is enough to make the machine knock.
- Run a spin with a small even load — If the noise goes away with an easy load, it was balance rather than a failure. That holds for every model the table on this page lists.
- Clean the drain filter and look for debris — Coins and grips live there, and they are the commonest cause of a rattle.
- Check the machine is level and does not rock — Press each corner in turn; any movement means the feet need adjusting.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel — a capacitor can hold a charge after the power is off. Turn off both taps before opening a hose, and have a shallow tray and towels ready: a drum and a filter housing hold more water than owners expect. Leave the door lock and its wiring exactly as they are.

Where the owner line is
Call when the drum is rough to turn by hand or the roar rises with the spin. Those two together are a bearing and the cabinet has to come apart.
