The short answer
The useful question on these models is whether the noise is a rumble, a squeal or a thump, because each belongs to a different part. A scraping that follows the drum round is the drum contacting the bulkhead, which means a glide has worn through. Establish the character of the noise before opening anything. The listing numbers are not all the same length, which on this brand marks a generation change rather than a different chassis.
What owners report
- A scraping that follows the drum round — The drum is contacting the bulkhead because a felt glide has worn through. It will damage the drum if left.
- The noise is worse with a heavy load — Load-dependent noise points at supports rather than at anything in the airflow path.
- A deep rumble that rises with drum speed — Worn drum support rollers. It grows steadily over months and is loudest on a full load.
- A squeal or chirp that starts cold and eases as it warms — A belt or an idler pulley. The change with temperature is the distinguishing feature.
- NEAR MISS — the drum does not turn at all — A machine that will not tumble belongs on the start page for this family, not here.
Ranked causes for these models
- Drum support rollers worn — First on this roster. The rollers carry the whole weight of a loaded drum for years, they run on small shafts, and as the bearings wear they produce a rumble that grows steadily and is loudest when the machine is full.
- Drum glides worn through — The felt or plastic pads the front of the drum rides on wear down, and the drum begins to contact the bulkhead directly. Scraping rather than rumbling, and it damages the drum if ignored.
- Drum seal failed — The felt seal at each end of the drum keeps air in and clothing out. When it goes, small items escape into the cabinet and the drum runs rough, which is a noise and a jamming risk at once.
- Motor bearing worn — Last. A motor bearing produces a noise that tracks motor speed rather than drum speed, and it is far less common than everything above it.
Work in this sequence
- Turn the drum by hand with the door open — Roughness, resistance or a catch once per revolution tells you more than a running machine does.
- Run the machine empty and compare — Noise that largely disappears with no load is a support problem rather than something in the airflow.
- Note whether a squeal changes as the machine warms — A belt or idler eases as it warms; a roller bearing does not care about temperature.
- Look into the lint filter opening with a torch — Coins and buttons that got past the filter are sometimes visible from here before anything is dismantled.
- Push the front of the drum up and down — Play at the front points at worn glides; play everywhere points at the rollers.
- Listen for whether the noise tracks drum speed or motor speed — The drum turns far slower than the motor, so the rhythm of the noise identifies which one it belongs to.
Safety before diagnosis
Safety
Take the power away first — at the plug, or at the breaker where there is no reachable plug — and treat any capacitor as charged until proven otherwise. Do not run the machine with a panel removed to locate a noise.

When this stops being owner work
Characterise the noise and check for play before calling anybody, because those two observations decide which part is involved and shorten the visit. Call at once for grinding, for a burning smell, or for a noise that appeared suddenly rather than gradually.
