My pfaff 7530 was working just fine......but I sewed on a sweatshirt and the bobbin locked up and now it won't move. I took out the bobbin and cleaned in there but still not working. Any ideas?
Clearance in bobbin area is small and it gets lint balled up in there. If polyester lint, it could even have melted and welded the space tight. Try turning handwheel backwards...really hard...and it will usually loosen up, then clean out the bobbin area. If you have compressed air, use that to blow it out.
