Try to tighten the top thread tension. Make sure the thread is going through the tension disc.

This problem maybe cause by the stepping motor being sealed or the main board problem. Please go to your local sewing machine mechanic.

I am not sure, but you can try this: when the tension of the thread obove is loose, it jams down. Different fabrics call for different tension. Try tightening it buy screwing colckwise above the needle. Use a piece of fabric to investigate the best tension for your proyect. Wish you luck.

This white disc is tension disk.Yes if that white disc is damaged it can cause the problem.But sometimes this white disc gets bit loose or misaligned and cause the problem.Remove the white disc out and refit it.Also clean the bobbin and see if that helps.------- The little white disc that sits under the black bobbin case. Unscrewed the white disc and remove it and the washer-shaped magnet. This allows you to get better access under the bobbin shuttle for cleaning.

usually there is a little lever you pull down on the left of the pressure foot which triggers against the buttonholing foot to get the right length buttonhole.

You need to decrease your top tension to fix this problem.

Hello

Possibly your bobbin is in the machine backwards or upside down. The thread needs to come off the bobbin in a certain way (or direction) specific to each machine. If it will fit, try flipping the bobbin over or around.

Another thing might be the thread tension, make sure you have threaded the feed from the spool of thread properly. Often it will do this on its own.

If the bobbin is in correctly and through the **** in the side of the bobbin casing, make sure the top is threaded correctly. The part the goes up and down, I don't know the name, but it is right above the needle and if the thread is not through this part you will get a mess on the underside.

I notice others on the internet have suggested its a threading error. Try cutting the thread at the reeel and pulling towards to needle to clean all the guides.

I had the same problem with a brother. Mine was a connection issue, the dealer told me to take a pencil eraser and erase the end of the foot control that is inserted into the machine. Make sure that you wipe it down very well after that then insert it into the machine. That was all mine took and now it runs again. Good Luck
