My Tula pink 570 is on its way back from repair for a second time ! She is only 4 months old. Fortunately we have an excellent dealer and has been collected next day and and it will be delivered back to us tomorrow, it seams it is a known problem for Bernina and the engineers have been told how to fix it, we have been told it was not something we had done and another customer has had the same problem of the machine seizing up completely. Almost tears here on two occasions!
