We have a combination washer / dryer. It has a buildup of baked fluff around and behind the drum seal. I think it's the fuzzy bits that fall off the clothes in the wash, getting baked into felt during the drying cycle. I clean the seal regularly, but this is behind the seal, towards the drum. I can reach bits of it with my nails and scrape chunks out (sporner alert), but that's not exaclty practical, and I'm wondering how deep does the rabbit hole go. I also feel that the drying is not as good as it used to be. The machine is only a year old but we use it a lot. Did anyone have the same problem? Any advice?
