Re: My Pfaff sewing machine has started to loop the top...
If the thread is looping underneath, you're top tension may be too loose or the thread may not be in the take-up lever. If it's looping on top, double check that the thread is in the bobbin tension or that the bobbin tension isn't too loose.
