My Viking Designer 1 seems to be falling apart. First the touch screen stopped working. I took the machine into my dealer for general servicing and to investigate this problem. The screen was replaced (about $100) as well as the buttons (about $20). The labor fees were covered by the $100 cleaning and checkup cost. Something was wrong with the screen installation, so back it went. About six weeks later I can only get the machine to stitch backwards. I go to show hubby the problem and demonstrate several stitches. This time I hit the stretch stitch and it starts to stitch forward again. Problem solved for a few days of sewing, though the fix stitch only worked some of the time and the backstitch none of the time. Then it starts to stitch forward in only tiny stitches no matter the stitch length setting, The latest word from the dealer's repair person is that she thinks, but isn't sure, that it's the feed dog motor (about $200), and the board behind the buttons will also need replaced ($30). I'm wondering if I should be trusting this repair person. She didn't say it was covered by warranty, but shouldn't the motor for feed dogs be covered by a 20 year mechanical warranty? Any other thoughts?
