I have a Pfaff Classic Style 2025 purchased new in 2004. While it was still under warranty it did a lot of crazy stuff and the dealer replaced the Logic Board. He had it a year, for one reason or another. I didn't use it much after I got it back as I was still employed. Since I am no longer employed I am using it a lot. I will be sewing along with a straight stitch and my quarter inch foot and the needle suddenly jumps to the left. Well that hits the needle HARD, sometimes breaks it. Sometimes I will be stitching along in any stitch and it will lock up and the display will show WD on the display. I called the dealer where I purchased it, and the same who did the warranty repair, he said it sounds like the Logic board is out again and it will cost in excess of $400 to repair (no warranty) or he will give me $300 on a NEW trade-in. I will find a different dealer if I ever decide to fix it. It will be difficult to trust a repairman.
