Hi, I was recently using my vented Bosch Classixx WTA74100GB tumble dryer and heard a scraping sound coming from inside. I then realized that one of the buttons (metal about 1p sized) came off a jumper and got stuck in the drum. Before calling out an engineer I wondered whether there was anything I could try to fix it myself?
unless you can find it and remove it no. it will be at the front . try getting a torch and a mirror to see if you can see it. if you find it may be possible to hook it out with something
