Did you get this fixed? Most common problems: 1. You broke a needle and the hole in your needle plate now has grooves cut into the edges of the hole that are grabbing your upper thread and holding it too long for the hook to grab it. Take your needle plate off and examine it closely with a magnifying glass. If there are grooves, purchase some emery cord and run it back and forth until the edges are smooth or buy a replacement plate. 2. You broke a needle and you have rough edges on your hook. Lean your machine back and examine the hook with a light. If there are rough spots on the edge of your hook, you will need to smooth them out with emery cloth. 3. You have either the wrong size needle or you have the needle in backwards or not perfectly straight and the hook can't pick it up each time. 4. Have you changed to pre-wound bobbins? They may not be large enough for your bobbin case. If you have regular bobbins, check to make sure that the bobbins don't have burrs on the edge of the bobbins. If they do, throw them away and buy new bobbins. Sometimes I get some bobbins that are not quite round. Weird but true. Examine them. Good Luck.
