steps
- check visible loose items
with the dryer off, unplugged and cool, look through the doorway for loose objects. note if the cabinet already rocks or sits unevenly. do not remove panels, move it or unstack it to investigate.
- leave the dryer off
keep it safely disconnected if the unusual noise continues. do not run it with a panel removed to find the sound.
- arrange a repairer
read the accessible full model and product-number revision and check the product page. use the dryer label on a stacked unit. ask a technician to check the roller, bearing, shaft and drive parts, including the wheel shape and centre mounting.
- have the repair checked
a damaged shaft needs separate attention. after fitting, the technician should check that the drum is securely supported and runs normally with the cabinet closed. continued noise needs another check.
