This is an issue of your upper thread tension, so take a look at this generic tension solution
If you are in a pickle with your bobbin case, check top tension and bobbin case are free of lint, reset the top tension to 4, and adjust the bobbin tension to suit......some more detail on how to do that, is here

I have this same machine and it does this sometimes, too. I've found it's usually due to a couple of things: 1. The thread is caught on the spool in the little **** that holds the initial starter piece. If you turn the spool around with the **** on the side away from the bobbin maker, that usually does it. 2. The needle is not in with the thread going from front to back (it may be in with the thread going from side to side). 3. The thread is bad. (I had one spool that actually had "lumps" in it!
Hope this helps - good luck.
