When that happens to my machine it means either I have put the bobbin going the wrong direction, or the needle is in backwards, it needs a new needle, or it is not thread properly. Do you have the manual?
Have you cleaned out the bobbin area? You might have a thread stuck in there. It amazes me how a thread would cause so much problem. One more things the thread you are using is the old way - it winds around the pool? Or is is like a cone and it should come off from the top? If it is that is the case - I had to use a thread stand - put it behind the machine and put the thread thru a hole in the bobbin so the thread will follow the correct path. (Hope that makes sense.)
