Hi, my dryer is 2 years old and started to make noise, my husband took apart and that’s what was inside the dryer, basically everything, at the side panels, bottom, front, back. Anyone else?
there is no wonder why tumble dryers overheat and catch fire looking at that - whilst it looks bad though I have had a few tumble dryers apart from time to time and the dust does get right inside the tumble dryer just like that - all makes as well I have had hoover and Beko ones apart before and they look , maybe not as bad as that, but still do have a certain amount of dust inside still .
all you can do really is clean the dust lint filter after every drying cycle or before a drying cycle , plus make sure any other vents of the machine are kept clear at all times and hoover the vents out with a nozzle attachment on the end of the vacuum cleaner hose, and also like you have done there take it apart and give the inside a good vacuum out from time to time
Like @andy_in_ireland has said, all dryers will get some fluff/lint inside, but that does look like an extreme case.
Is your lint filter still in good working order? Check out this guide for help cleaning it https://www.samsung.com/uk/support/home-appliances/how-to-clean-the-lint-filter-on-a-tumble-dryer/
