have you fiddled around underneath to see what's there? there's a lot going on there and something as small as a piece of lint can cause it to sieze up. don't blow air in. oil everything and if you have a little vacuum, try that. clean everything down with a lint-free oily rag.
Not yet, had to deal with neighbor drama. I wish I lived in the country!! I am going to go see if I can find an attachment for my vacuum to help clean out the machine.
