Bernina 770 problems
1.Continually 1010 error Main Drive Sync failure- machine stops and needle won't go up & down. If I remove the bobbin it frees the needle
2. Placement of the hook is extremely difficult. Can I be putting the hook in upside down? The threads gather behind the hook very frequently.
Can anyone help me please?
I can't keep sewing until I get some help?
