My singer 7470 keeps jamming on me. I have taken the bobbin out and it still keeps jamming. When I sping the handle in reverse it will work fine. When it goes forward it jams up. I called singer customer support and they have never heard of this problem before. Any suggestions?

To learn how to solve bobbin jam and select the correct needle, I suggest you to order the following product:

try changing the needle
make sure the bobbin is turned the correct way in the bobbin case
make sure the top thread has not come off the thread take up lever
if these suggestion don't help then the machine needs to be checked to see if it needs some type of adjustments
Sounds like your machine is off timing, When the machine is properly timed, you should see the hook passing behind the eye of the needle when the needle is on it's upward stroke. If this is not correct the machine will not pick up the bobbin thread. You may have to take it in for adjusting, unless your a bit machnical.
I would say that the threading is wrong somewhere, watch your dvd and read the owners manual, also go to Singer.com FAQ for your machine, If the jamming is underneath, it is the top threading problem, on top, it is the bobbin thread either has lint or stray thread or thread not coming out the right direction for your bobbin, I am sure that it is just a simple solution, I also use metal SA 156 bobbins and have no problems,
I am having somewhat the same problem with the exception that my needle did not break. I've cleaned and oil, but the bobbin case and projection positioned spring is not communicating to allow sewing to continue. The thread keeps jamming and the bobbin raises up the plate. So, what else am I to do?
