Bernina have just come back to me. I am to take it where I bought it from (next large town to us), their technician will be there and he will have a look at it. They will lend me a machine if it is something they cannot do immediately and I have been told they will replace the machine if it is too serious. It is still under guarantee as it is only 9 month old. I do not think I can ask for better service.
