Quick summary
Rhythmic banging usually comes from hard objects (metal buttons, shoes) or levelling. Constant squeaking or scraping may be rollers, bearings or drum felt and needs checking.
Some sounds are normal—drum rotation and the compressor in heat-pump dryers. New squeaks or knocks usually mean friction or a trapped object.
Unplug the appliance, close the water tap if there's a leak, and never open covers that need tools or expose wiring or circuits.
Possible causes
Hard objects in clothes
Metal zips, buttons or coins.
Not level
Vibration and knocking, especially stacked without the right kit.
Rollers or bearings
Rhythmic squeak with rotation.
Belt or idler
Rattling or slipping.
Drum felt
Rubbing when the felt wears.
Safe checks you can do
- Empty pockets, close zips and turn items with metal buttons inside out.
- Check the dryer is level and stable; if stacked, confirm the stacking kit.
- Unplug and inspect the drum for trapped objects.
When to stop checking immediately
- If the sound is metal scraping or comes with a burning smell.
