The short answer
A dryer is a heavy drum turning on cheap consumable parts, so nearly every noise it makes is one of those parts reaching the end of its life. What the noise is tells you which one, and the drum does not have to come apart to find out. On a Eurodesign dryer the place to start is how the machine is standing and how it is vented, because the moisture-sensing and control chain decides when this dryer stops, so it outranks the heater on the list.
What you actually observe
- A high squeal that rises with the drum — Dry rollers or a dry idler pulley.
- A rattle or a scrape only at the start — Glide strips worn through, so the drum rests on metal until it lifts on speed.
- A metallic ticking on every turn — Almost always a coin, a nail or an underwire that has found its way past the drum seal.
- NEAR MISS: a hum with the drum not turning — That is a seized bearing or a broken belt, not a noise complaint.
Causes, most likely first on this brand
- The machine is unlevel, or its vent is resonating — A dryer that rocks on three feet bangs on every load change, and a loose transition duct drums against a wall behind the machine. Ranked first on a Eurodesign dryer: these are built-in units fitted into a cabinet opening, where the install decides the door line, the clearance and the drain fall, and where nothing inside the machine has usually failed at all.
- A foreign object in the drum or behind the baffle — Coins, buttons, underwires and pen caps get past the drum seal and rattle round the blower housing or the front bulkhead. Where it sits here: always first, because it is free, quick and the single most common cause of a new noise in a dryer that was quiet yesterday.
- Worn drum rollers, a dry idler pulley or a tired belt — The drum rides on rollers and is driven by a belt held in tension by an idler. Where it sits here: the mechanical cause that dominates on any dryer past its first few years, whatever badge is on the door.
- A blower wheel that is fouled, cracked or loose on its shaft — The blower moves all the air through the machine, and anything that gets into it rattles continuously while the drum turns. Where it sits here: less common than the drum parts and easy to distinguish, because the noise follows the motor rather than the drum.
Check in this order, and why
- Start at how the machine is standing and how it is vented — It is the cause that ranks first on this kind of machine, so it is the check that ends the diagnosis most often and the one that costs least to make.
- Empty the drum and turn it by hand with the power off — Roughness, catching or a repeating bump felt through your hand localises the fault before any panel comes off.
- Run it empty for a minute and listen — A noise that persists empty is mechanical.
What an owner can safely do
- Check the lint trap housing and the drum seam — Pull the screen, shine a light into the housing and feel round the drum lip.
Tools: flashlight, tweezersAbout 15 min
- Level the machine and secure the vent run — Wind the feet until it sits solid on all four, then clip the transition duct so it cannot touch the wall or the floor behind the machine.
Tools: adjustable spannerAbout 20 min
- STOP HERE before opening the cabinet — Rollers, idlers, belts and glides all sit behind the front or rear panel, and getting to them means the machine comes apart.
Before you open anything
Safety
Unplug the dryer or switch off its breaker before removing any panel; a capacitor can hold a charge after the power is off. On a gas dryer, close the gas shut-off valve before moving the machine and do not disturb the flexible connector. If you smell gas at any point: do not switch anything on or off, leave the building, and call the gas utility from outside. Do not look for the leak yourself.
When to call a technician
Call when the noise is mechanical and persists with the drum empty, when the drum feels rough turned by hand, or when laundry is coming out marked as well as the machine being noisy. A worn roller left alone eventually takes the belt with it, so this is a repair worth booking rather than deferring.

What this page does not cover
This page covers Eurodesign dryers as a class, not one family or model line. Where a family- or model-specific page exists for your unit, that is the more specific answer and the one to read first. Deliberately not here: roller kit part numbers, belt lengths and glide references, all of which differ by family.
