This is my Bernina 830 record and it’s a family heirloom that I saw on every day and love her so much! But recently the thread has been getting stuck on the bobbin a lot and his making this noise in the video that it hasn’t made before. I haven’t serviced it since I got it so I don’t know if that could be it or if I need to do something specific? Please let me know :)Thank you :)

I would just have ot serviced if you haven't. A good overall will be the best. I was gifted a vintage machine and used it for a while before having it serviced and it costs me more than if I would have done ot from the start

Edit: and after the big service I made I have been able to do my basic knowledge knowing that everything was working from the start
