With no pressure on the foot pedal, the presser foot and needle just start going up and down until I shut the machine off. If it was turning out quilts I wouldn't complain, but it just knots up thread under the throat plate. The machine is just over a year old and the problem started a few months ago. It doesn't happen every time and, of course, didn't happen in the repair shop so they couldn't diagnose or repair the machine.
I did try unplugging the machine and restarting it, cleaning it, detaching the foot cord, cleaning the foot pedal, ect, ect, ect Nothing ever helped.
I had a Pfaff passport 2.0 that did that. It sometimes would not sew. Lights would come on, just would not sew. Sometimes it worked fine. Yes, one time it just took off while I was staring at and then went full speed and it would not shut off until I pulled the plug. Brought it in a couple of times. It never did that at the dealer. The tech thought it might be just the tiniest speck of dust or static that would trigger it. I still have that machine, but should probably just bring it to the recycling center as I can't sell it anyone and I sure don't want to use it. It is a boat anchor. Let me know if it is the same machine
