I have had many Pfaffs...in fact I think I should hold stock. Now, my 1473 from the dark ages, but which I still love....when you put the thread in the bobbin, it should go counter clockwise. On my newest Pfaff, the Creative Sensation...it is the opposite. I had the same problem you describe when I tried to load the 1473 with the bobbin going clockwise. I sure hope this helps, having a new machine is such a thrill and having problems with that same machine is just the PITTS.
