Report "I just bought this machine and I am trying to wind the bobbin. The instructions say to lift the presser foot after you have threaded the machine properly to wind the bobbin and then the light will turn green. Mine stays red. I have threaded it correctly and tried several times. The light is green when it is in sew mode, but not when I slide the bobbin threader to the right and lift the presser foot. Is it a defective machine?"
