I bought a Bernina 830 a year ago. I was so excited. I knew it would be wonderful to sew with. Wrong! The thread breaks all the time. I've used every thread possible. I've used every needle possible. I even bought a vacuum for sewing machines and clean it frequently. One of the feet that came with it won't work. The dealer let me try one of their's and it wouldn't work on my machine, so they gave me a similar one and a couple of months later asked for it back. I said "no" and reminded them that the one that came with the machine wouldn't work on mine. It's the open toed foot. Good for appliqueing. The metal one wouldn't work but the plastic foot does. And my machine always tells me the thread is broken when it's not. I'm just really disappointed. This machine is suppose to be the cream of the crop. That's why I bought it. My old Viking works better than this one. Anyone else with a Bernina 830 having any of these problems?
