I had a Pfaff several years back. The foot lifter would not stay up. Took it to the repair shop waited 13 weeks for them to get the part in. Picked it up went back home ,30 miles, plugged it in and heard a whirring noise. I put it into the car and I was steaming. waiting all that time and now have a new noise. Took it back and was ranting and raving at the salesclerk. She plugged it in and she unengaged the bobbin winder and said."Is that hte noise you heard?" I was so embarrassed that I could have screamed...
