Asko T Series Dryer is the scope of this page, and on it a new noise or vibration points first at worn drum rollers or support wheels. The brand page puts a coin, a button or a wire in the blower or the drum first; here it moves down, because what sits behind which panel on these models changes what is worth checking first. 2 of the 6 causes below can be checked without a tool; the rest need a technician.
What the machine is doing
- A squeal or a chirp that rises with the drum — A dry bearing or a roller, and it usually gets worse rather than better.
- A rhythmic thump once per drum revolution — Anything that repeats exactly once per turn is attached to the drum.
- A rumble or grinding from underneath — Below the drum is where the motor, the blower and the idler live.
- A scraping from one side of the drum — A glide or a felt seal worn through, so the drum is riding on metal.
- A rattle that only happens sometimes — Something loose, most often in a pocket or caught in the blower.
- NEAR MISS — noise plus a burning smell — Stop the machine and unplug it. That is not a noise complaint and it should not wait.
Causes, most likely first on the T series
- Worn drum rollers or support wheels — It is the commonest mechanical wear item in a dryer, and it usually announces itself for months before anything actually fails.
- A coin, a button or a wire in the blower or the drum — The blower wheel is downstream of the lint screen and catches anything that gets past it. A coin in there is the classic intermittent rattle.
- A tired idler pulley or belt — A belt that has begun to fray slaps rather than squeals, which is the one-per-revolution thump people describe.
- Worn drum glides or a failed felt seal — Glides carry the drum front and back. Worn through, the drum rides on metal and scrapes, and the noise sharpens when the machine is loaded.
- A loose or damaged blower wheel — Because it is downstream of everything, it is also where objects that got past the screen end up.
- A machine that is not level or is touching something — A dryer rocking on three feet drums into the floor, and one touching a wall or a neighbouring washer passes everything into that instead.
What to check first, second, third
- Rock the machine at each corner — Free, quick, and it is the answer more often than any component on this list.
- Decide whether the noise repeats once per drum turn — Once per revolution means something on the drum. Continuous means something spinning faster than the drum.
- Only then think about rollers, belts and bearings — They are behind panels and they need the machine opened, which is where the owner line falls on many models.
Before you open anything
Safety
Nothing below happens on a live machine. Unplug it or switch off its breaker before any panel comes off, and remember a capacitor can hold a charge after the power is off. Never run a dryer with its duct disconnected into the room. It puts moisture and lint into the house and it leaves the machine running hotter than it should. Work with the machine cold, dry and isolated, and stop at the first step that would need it powered.

When to call a technician
Where to stop: what you can see, reach and clear with the machine isolated is owner work; any test with a meter, and any work inside the cabinet with the drum or the blower exposed is not. On this page that puts worn drum rollers or support wheels on the far side of the line. Call immediately if the machine has to be held, propped or forced to work at all, because a workaround on a fault like that has a short life.
