Hello!

I have a Bernina deco 340. While stitching out a design I had a thread jam, once I was able to unjam it and clear away all the loose threads, I re-threaded it and backed my design up and tried to start again. However, it was not pulling the bobbin thread through and the upper thread end or threak breakage warning would pop up.

I changed needles, placed a new bobbin in, re-threaded my machine and it is still doing this! Just not moving the bobbin thread at all.

After trying everything several times (several new needles, re-threading bobbin and top thread,checking for remnants of strands in the bobbin case etc.) I turned off the machine and called it night!

Tried again this morning and it is still doing the same thing!

Why is it thinking there is a thread break when it isn't even sending the bobbin thread through? And any idea how to fix this?

Thanks
