The answer first
A BWDB line washer that grinds on the spin and is quiet in the wash is loading its bearings, and on these models that noise arrives with a spin that never reaches full speed. Two symptoms together are worth more than either alone.
What this looks like in the kitchen
- A hollow booming at particular speeds — Cabinet resonance, usually with a machine that is touching a unit or a wall.
- A scraping from inside the drum — An underwire or a hair grip through a drum perforation scrapes on every rotation and eventually marks the laundry. What separates the BWDB line here is the order, not the parts.
- A grinding or roaring that rises with the spin speed — A roar that tracks the spin ramp is the classic bearing signature.
- A drone that is present at every speed — A motor bearing rather than a drum bearing, because it does not track the drum speed.
- A high-pitched squeal during the wash — A squeal that follows drum rotation rather than spin speed is friction, not bearing wear.
- 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 noise only happens with a duvet in — That is a load problem rather than a machine problem, and it will happen to a healthy machine every time.
Causes in likelihood order
- A motor bearing rather than a drum bearing — Top of the list here. The pitch behaviour is the whole diagnosis between these two. On the models listed in the table on this page the access for this is the same across the line.
- Foreign objects in the sump or the filter — Second on this list. Coins, buttons and grips escape pockets, pass the drum and land in the sump, where they rattle against the pump housing on every cycle.
- Coins or keys between the drum and the tub — Third most likely. Anything in the gap is urgent: it damages the machine while it makes noise. The BWDB line puts this within reach without a teardown.
- Worn suspension dampers or springs — Further down. Damping wears out gradually, so the machine passes balance checks less and less well and eventually knocks on every spin.
- A foot that has dropped or lost its lock nut — Fifth. One foot out of adjustment lets the cabinet rock and turns every spin into a knock.
What to check first, second, third
- 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.
- Clean the drain filter and look for debris — Coins and grips live there, and they are the commonest cause of a rattle. On the models listed in the table on this page this is the check that decides the job.
- Note whether the pitch rises with the spin — Rising pitch is the drum bearing; constant pitch is the motor.
- Empty the drum and turn it by hand — A healthy drum turns smoothly and quietly. Grinding or a rough spot points straight at the bearing.
Isolate it first
Safety
Unplug the appliance or switch off its breaker, then shut the water off. Never run a cycle with a panel removed, and leave the door lock exactly as it is: it keeps the drum shut while it spins and that is its whole purpose.

Where the owner line is
Book a visit if a scraping noise persists after the filter and the drum have been checked, because something is likely between the drum and the tub and it will cut through given time.
