Before I would listen to your Pfaff dealer's advice, I would contact 15 other dealers to see if you ge the same answer. Last year my mother's 1952 pfaff had to go to the shop after she had uppolostered all the cushions in a used camper. Her pfaff dealer took the machine in and kept it for two weeks. When she went in to check on the machine, he told her it was unrepairable but he would give her a "good" tradein on a new machine. My mother is 87. She brought the machine over here to texas on her next trip and asked if I had a person who worked on my machines. We took the machine over to my service guy. She went home that weekend and I called a week later to check on the machine. He asked me who had worked on it, and I gave him the story. The only thing wrong with the machine was it needed to be cleaned and her dealer had wired the motor backwards......So much for dealer knowledge.....So it cost me $20 to have the machine cleaned....I took her machine back and it hasn't stopped running. My guess it will be my inheritance unless my sister gets there first. (It would be ok I have 2 pfaffs now)
