The short answer
A new noise from the BDCB line is usually something in the drum or a worn support rather than a failing motor. These cabinets carry the drum on rollers with a belt drive, so the classic wear noises are a regular rumble and a rhythmic squeal, both of which change character as the drum loads.
What you observe
- A sharp clatter that follows the drum rotation — On the models listed in the table on this page, something loose in the drum or caught in the lifter, which is by far the most common reported dryer noise.
- A regular low rumble that grows with the load — Worn support rollers, which carry more weight as the drum fills and therefore get louder rather than quieter.
- A rhythmic squeal from the cabinet — A belt or an idler running dry, which usually warms up and quietens slightly as the cycle proceeds. The models in the table behave the same way here.
- NEAR MISS: the noise arrives with a load that stays damp — Then the drying fault is the primary one and the heating-failure page for this family is the better starting point.
Causes, most likely first
- Objects loose in the drum or caught in a lifter — First on the BDCB line by a wide margin. Coins, buttons and wires from underwiring lodge behind the lifters or pass into the seal gap, and they produce a loud rotational clatter with nothing worn at all. That holds across every model this page covers.
- Worn drum support rollers — Second because they are the wearing part on this platform. The noise is a low regular rumble that grows with the load rather than a sharp knock, and it develops gradually over months. That is true of every model this family spans.
- A glazed or slack drive belt — A belt that has hardened squeals at the idler, especially from cold, and the sound often fades as the machine warms, which makes owners dismiss it.
- A cabinet that is not level or a loose panel — Free to fix and very common after a machine has been moved. A dryer rocking on three feet transmits every normal vibration into the floor.
- A failing drum bearing or motor bearing — Last on this platform because it is uncommon and because rollers, belts and loose objects imitate it. A genuine bearing noise is continuous, load-independent and usually preceded by months of rumble.
Check in this order, and why
- Run the machine empty for two minutes — First on the BDCB line because it separates the load from the machine immediately, and because loose objects are the most common cause by a wide margin. It is the same on all the models in the table on this page.
- Check the pockets of everything that went in — Coins and keys are the usual finds, and a single one behind a lifter produces a noise owners describe as catastrophic.
- Turn the drum slowly by hand with the machine isolated — For every model in this family, a rumble or a rough spot felt by hand points at rollers; a smooth turn with noise only under power points elsewhere.
- Rock the cabinet and check all four feet — A machine resting on three feet rattles at particular speeds, and levelling is a two-minute job with a spanner.
- Listen for whether the noise grows with load size — Roller noise grows with weight; belt squeal does not. This is the cleanest way to separate the two by ear.
Before you begin
Safety
Unplug the appliance or switch off its breaker before removing any panel. A capacitor can hold a charge after the power is off. Let the machine cool before reaching into the drum, since the drum and its seals stay hot for some time after a cycle.

When to call a technician
Call when the drum is empty, the cabinet is level, the panels are secure and a continuous noise remains that does not change with the load. On the BDCB line that points at a bearing or a seal behind the front bulkhead. The same is true of each model covered here.
