The short answer
A new noise on a Conservator VDEW dryer points at one of four moving parts — the drum supports, the belt and its idler, the blower wheel, or something loose inside the drum. The brand-generic page tells you to separate the noises by when they occur; that still works, and this family decides which support to suspect first. On the electric half of this pair the heat side of the ranking is an element and its thermal protection, not an ignition sequence, so the checks that dominate the gas page do not apply here at all.
What you observe
- A rhythmic thumping that keeps time with the drum — Something turning with the drum: a flat spot on a roller, or an object caught in the drum seam.
- A high squeal that rises as the drum comes up to speed — A dry roller bearing or the idler pulley, and it usually arrives gradually over weeks.
- A rattle or ticking that varies with airflow rather than with the drum — The blower wheel, with a coin or a button reaching it through the lint path.
- A deep vibration felt through the floor — Levelling, or the machine walking on a smooth floor under an uneven load.
- NEAR MISS — a noise that arrives with clothes still damp — Then the noise belongs to a drying or airflow fault and the heating page is the one to read.
Causes, most likely first on the VDEW models
- Drum support rollers and glides — First on this family. They carry the whole weight of a loaded drum and they wear flat rather than fail, so the noise arrives as a thump that gets louder over months while the machine still dries perfectly.
- Object in the blower wheel — Second, and it is the noise most often mistaken for something catastrophic. Coins and buttons travel down the lint path and hit the blower wheel at speed; the noise is alarming and the fix is small.
- Belt and idler pulley — Third. A dry idler squeals and a worn belt slaps, and both produce noise well before either stops the drum turning.
- Object in the drum seam or a pocket — Fourth, and free to check. Zips, coins and the corner of a metal fastener will thump convincingly enough to suggest a bearing.
- Levelling and floor contact — Last on the list but first to eliminate, because it costs nothing and it amplifies every genuine noise above it.
Check in this order, and why
- Establish the heat letter on the plate first — Confirm the letter on the plate before anything else; a check written for the gas twin will waste an afternoon on a machine that has no burner.
- Empty the drum and run it empty for a moment — A noise that disappears with an empty drum was a loose object or a load, and the job is done.
- Note whether the noise keeps time with the drum or with the air — Drum time points at rollers, belt and seam; anything faster and steadier points at the blower.
- Rock the machine at each corner and check the feet — Free, and it removes the vibration complaints that are not faults at all.
- Only then plan to open the cabinet — Rollers, idler and blower all sit behind panels, and this is the point at which the job stops being a two-minute check.
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. A dryer runs on a heavy circuit and its cabinet comes apart in a way that exposes both the heat source and the drive, so isolate at the breaker rather than trusting a switch. Never run the machine with a panel off to locate a noise: the blower and the belt are both exposed and both are moving fast. Clear the lint path while you are in there, because lint around a heat source is the fault that turns a noise complaint into something far worse.

When to call a technician
Call once the load, the levelling and the empty-drum checks are clean, because everything that remains sits behind the cabinet panels. Call once the fault sits past the thermal protection, because an element circuit carries the heavy leg of the supply and is not owner work. Call rather than continue if the noise is accompanied by a burning smell, since that combination points at the lint path rather than at a bearing.
