Bernina sewing 804 minimatic sewing machine
I hope I am posting this in the right place and doubly hope someone can help me. I took my Bernie to class today, I was teaching FMQ and this machine is superb for that but the needle kept on stopping working but when I moved the inner wheel on the side of the machine, the one that engages and disengages when winding the bobbin it started again, but after doing this 3 - 4 times it stopped completely. The motor was running but the needle was operating. How do I get into it to see if anything has come adrift!
I hope I have explained myself properly.
Pretty please do tell me that if is mendable as I adore this machine.
