Singer 7470 jams and buzzes

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?

    I have the same problem. I can't get the sewing machine to advance when I sew. The underside gets all knotted up even after I carefully thread it correctly. It was working okay before, but can't get it to sew evenly now.

If you get it unjammed, be sure to install a new needle as the old one is probably damaged. If there are still issues, the machine's timing may be off and would need professional service.

I have Singer Machine 7470 and when i try to fill the bobbin on top of the machine it make a noise and it wouldn't spin it keep making a noise. Please help


Noisy top bobbin winders is usually caused by no oil on the spindle, or the noise could be coming from a dry top shaft under the balance wheel which is very common

I have a Confidence 7470 purchased in May 2009. I was sewing tulle today and the thread kept snapping while sewing. I assumed it was catching in the tulle. The last time it snapped, the thread jammed in...


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.

Singer simple the machine keeps jaming


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,

Keeps getting jammed


Hello,
Give these solutions a try.

* Un-thread your machine and remove your bobbin. Clean any loose thread or lint out of your
bobbin case. Re-thread your machine, reinsert and re-thread your bobbin.

* Change your bobbin as there could be a nick along the edge of your bobbin spool that’s catching your thread as you sew.

* When you start to sew a seam, Hold the upper and bobbin thread tails back and out of the way as you sew your first couple of stitches. This will keep them from getting jammed in your machine.

I hope this helps.

Bobbin case case keeps jamming


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?
