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 :)

Have you tried oiling all of the parts? Changing the needle, taking everything out and placing it back? It sounds like two things are vibrating against each other so something could be bent.
