Start here
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 Finlux dryer the place to start is whatever is loose in the drum or under it, because the moisture-sensing and control chain decides when this dryer stops, so it outranks the heater on the list.
What you are looking at
- 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.
- A rhythmic thump once per drum revolution — Something on the drum rather than under it: a worn roller flat, or an item trapped between the drum and the bulkhead.
- NEAR MISS: a hum with the drum not turning — That is a seized bearing or a broken belt, not a noise complaint.
What it usually is, in order of likelihood
- 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. Ranked first on a Finlux dryer: these machines run a programme that will not advance until its own checks pass, so what has been asked of the machine matters as much as what is wrong with it.
- 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. Where it sits here: worth a minute before anything comes apart, since it is free and reversible.
- 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.
The order to work in
- Start at whatever is loose in the drum or under it — 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.
Owner-side checks, step by step
- Clear the vent run end to end — Disconnect at the machine and at the wall, brush the duct through and check the outside flap opens freely.
Tools: vent brush, screwdriverAbout 45 min
- 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
- 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.
Safety first
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 this becomes a service call
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.

The limits of this page
This page covers Finlux 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.
