The answer first
BSW models take this one slightly differently. The noise tells you which part of the cycle is failing. A rumble that only appears at high spin is usually balance or bearings; a metallic scrape at any speed is something caught between the drum and the tub. The departure from the generic page is in where the first check goes.
What you observe on a BSW unit
- A metallic scrape or rattle as the drum turns — Something trapped between the drum and the outer tub, which is a free fix if it can be reached. On the BSW line this is where the checking starts.
- Banging during the spin with the machine walking across the floor — Load balance and levelling rather than a mechanical failure.
- A humming with the drum not turning at all — That is a different fault: the motor or the belt, and it belongs with the cycle-fault page.
- NEAR MISS: the machine is noisy and also leaking — A failed bearing seal leaks as well as rumbles, so start with the leak page if there is water.
Causes in likelihood order on the BSW line
- An unbalanced load — Ranked first because it is the most common and the most completely free: a single heavy item, or a load that has knotted itself into one lump, makes a machine bang and walk at spin. On the BSW models this stays at the top because nothing about the platform makes it less likely.
- Worn shock absorbers or suspension — The drum is no longer being controlled at load, so the machine is quiet when empty and loud when full.
- Worn drum bearings — Last of the mechanical causes and the most serious: a deep rumble that rises with spin speed, gets worse over months, and eventually takes the bearing seal and the tub with it.
Where to start, and why
- Run a spin with the drum completely empty — A quiet empty spin points at the load; a noisy one points at the machine, and that is the single most informative test here. The BSW layout is the reason it comes first here.
- Check the back panel for transit bolts if the machine is new or has moved — They are usually four bolts across the rear panel and they are missed constantly.
- Feel around the bottom of the door seal for trapped objects — Coins and underwires collect in the seal fold before they work their way past it.
Isolate it first
Safety
Power off at the plug or the breaker first, and leave it off while you work. Never try to open the door during a spin or interfere with how the door lock behaves; the machine is designed around that lock and it is there to keep the drum contained.

When to call a technician
The line is the outer tub. Everything you can reach from the door, the seal or the filter is yours; anything that needs the tub opened is not. Call immediately if the drum has visible play and the machine is also leaking, because the bearing seal has gone.
