IT PROBABLY IS THREADED INCORRECTLY. GO SLOWLY BY THE DIAPHRAGM AND MAKE SURE IT IS THREADED CORRECTLY. ALSO MAKE SURE SPOOL PIN HOLDERS ARE IN PLACE THAT HELPS TO GUIDE THE THREAD CORRECTLY.

SOURCE: Machine is jamming
You need to remove the bobbin from the "race" by following the instructions in the manual. Give it a good clean and remove any bits of fluff and thread. Remove the upper thread also andmake sure that the tension wheel is clear of any broken threads and is on the correct setting. It may have been threaded wrong. The hand wheel not turning sounds like the bobbin area is jammed also.

I'm new to sewing, and I had a similar problem where the top thread went all the way around the bobbin thingy and got stuck every time--solution: the bobbin case wasn't all the way in. The arm had to go in a slot at the top and it sort of snapped in, then it worked fine. Maybe it will help you!

Either upper thread is not passing through thread sensor area or sensor is broken.
Second possible reason is that if design is not optimized the sporadic speed change provides thread breakage error even if the thread is not broken physically. Make sure your software is updated to optimize it automatically (Futura main menu->Help->Live Update).

I had the same problem for a LONG time. Yesterday I finally removed the top and the cover for the upper tension and found thread fragments under one of the discs. I removed it and used compressed air for dust clean out and it is working wonderfully. Good Luck
