The short answer
On the Black Decker BCED dryer an unfamiliar noise is usually the drum support rather than anything in the air path. The BCED table is a size ladder rather than a set of designs, so the same checks apply across the model list in the table. The most useful of them costs nothing: switch the machine off and turn the drum a full revolution by hand before you listen to anything.
What you observe
- A rhythmic thump once per drum revolution — Something on the drum or its support: a flat on a roller, a worn glide, or a seam catching.
- A metallic rattle or scraping that comes and goes — Usually a coin, a button or an underwire that has passed the filter and is loose in the blower housing.
- A high whine that rises with the cycle — A bearing under load — motor or blower.
- A squeal that fades after the first few minutes — A dry glide or a belt on a cold machine.
- NEAR MISS — noise with a drum that will not turn at all — That is a jam or a broken belt and belongs on the page for a machine that will not start.
Causes, most likely first on the BCED family
- Drum rollers, glides and the rear bearing — First on this family — the BCED table is a size ladder rather than a set of designs — and the drum in a compact cabinet is carried on small supports that take the whole load: once one wears a flat, every revolution announces it and the sound grows over months.
- Belt and idler — Second: a hardened belt or a dry idler squeals on a cold start and then quietens, which is exactly how you tell it apart from a roller.
- Hard objects in the blower or filter housing — Third — the cheapest cause on the page and worth clearing whatever the ranking says, because it takes a minute and rules out a whole class of intermittent rattles.
- Motor and blower bearing wear — Last: a steady rising whine that does not vary with load or warmth and gets worse every week.
Check in this order, and why
- Turn the drum by hand, slowly, right round — First and most informative: a flat spot or a catch is felt rather than heard, and it names the top cause immediately.
- Listen for whether the thump is once per revolution — Second: rhythm tied to the drum is support; rhythm tied to nothing is the blower.
- Run it empty, then loaded — Third — support faults get louder under load and blower faults do not.
- Check the filter housing for anything hard — Last of the free checks, and still worth doing on every machine before booking anything.
Before you open anything
Safety
Unplug the appliance or switch off its breaker before removing any panel or reaching into the drum — a capacitor can hold a charge after the power is off. Never run the machine with a panel off or the door switch defeated to chase a noise. Lint is fuel: clear the filter and the air path whenever a panel is open. Get a second pair of hands before tipping or moving the cabinet.

When to call a technician
Call when the noise is a steady whine that rises with running time, ignores the load, and survives an empty drum — that is a bearing and it only worsens. Call immediately if the noise arrives with a burning smell or with a drum that has become hard to turn by hand.
