In addition to what Roxann said, I would get that machine to your tech as soon as you can. He can read the error message that you got from the first problem, and maybe save you a lot of aggravation about your mother board on the machine. My old 1530 finally bit the dust with a blown motherboard. Such a sad day. I wouldn't push my luck on using the machine until it can be checked. I don't like the part where you said it made a noise and stopped. Sometimes it's just one part of the board that needs to be worked on. Unfortunately, Bernina no longer stocks the board for the 1530. I can ask my tech for you. He started out working at Bernina of America and is one of the country's best Bernina techs. He has been maintaining my Berninas for at least 15 years. Always gives me straight info.
