Thread breaks! Janome 8900 QPC
I have had my Janome Horizon 8900 QPC for two weeks now. The last few days, I have had a lot of upper thread breaks while FMQ. I have changed my bobbin, changed my needle, re threaded the machine and it is still happening! I can sew about 50-100 stitches and it breaks again! I took it in to the dealer today and he told me it could be the bobbin tension. I bought another bobbin case and he adjusted it with a looser tension for FMQ. Still having same issue! I am so frustrated! Anyone having similar issues?
