I started using dryer sheets because we can't use fabric softener in the condo complex I live in (Septic System). One got stuck between the drum and the felt seal up front. I was able to pull it out. But now there is this metallic sound like something scraping, almost like a squeal. Tried to find repair manual online but there is not one to be found. The unit is only 1 year old, just out of warranty 1 month. From what I've seen on youtube it may only get worse. Any thoughts on this?
