Sorry to hear that you have problems with your bernina - all good advice here, I would contact bernina headquarters for 2 reasons, 1 is the machine, 2nd is their agent. Hope it does some good contacting the viking dealer did not work for me. I got a new viking 875 quilter which is quirky, been back to the dealer 4 or 5 times, no luck from viking either as the dealer says the machine does work correctly. Well, for me, it runs like an engine on 3 cylinders, very loud and vibrates so much when I am strip piecing that the needle gets blurry to my old eyes. I will probably lose my hearing if I sewed continuously.
