Sorry to hear of problem with needles, but are you using the correct pressure foot and is the needle in the right position (ie, left, right or centre?)?
After breaking 4 in a week recently as soon as I went to sew, I realized that I had ignored machine telling me to change feet because needle was set to left position and kept hitting the foot, I decided to remove the foot adapter every time I turned the machine off until I remembered to double check everything before sewing :roll: Good luck with next try.
