Everytime I have this problem it is because the top thread is not in the tension discs. Be sure and thread your machine with your presser foot up, and don't lower the presser foot until you are ready to thread the needle. This makes sure the tension discs are open when you are threading, and when you lower the presser foot it tightens the tension discs.
