I haven't experienced that particular problem..yet, but recently I was all set up to do some sewing and my machine would not sew. It made noise, but no movement. It was locked up. After messing with it for a good half hour or better I was seriously thinking of putting it in the garbage. As I was picking up items to put away, I noticed that the spindle that I have to use for rewinding a bobbin was pushed into the threading position. Pushed it back and lo and behold...everything was working. I'm sure my face was a little red, but I could sew again. I now check the rewind spindle first. Live and learn. Hugs
