The auto stop/go button is stuck in and won't release? How do I get it to release?

SOURCE: i can't sew on my machine

I had the same problem.There is a gold or silver washer on the back of the sewing machine that holds the part inside that you are connecting to. If the washer is gone or loose you will not get a connection when you insert the foot peddle. This peice inside is small and square with three delicate wires attached, You should be able to see it

SOURCE: presser foot lifter is stuck can i fix it

If you can't lift the presser foot up at all undo the presser bar screw on top of the presser bar, if you have a dial turn it to 0, you should now be able to move the lever, if it is still tight put some WD40 on the presser bar and leave it for a couple of hours.

Can't answer your problem, my problem also. But I don't have the auto button, so I am really stuck. Was hoping you got the answer and did not have time to post.
