Here are a few sites that may be helpful in diagnosing your problem:
NUMBER ONE SUGGESTION--install a brand new needle. Sewists are known to be very frugal about changing needles but it is usually the easiest and least expensive fix for a lot of problems.
Remove all the thread from your machine, clean the bobbin area of any lint, threads, etc. Be sure that you RAISE the presser foot BEFORE you thread the upper thread. This releases the tension disks so the thread will seat properly. Now, re-thread from the beginning verifying you are following the correct threading sequence (consult your manual)

Why Does My Thread Keep Breaking While Sew
You re probably here because you re...
Possibly the top thread is being restricted in movement
check that the thread is between the tension plates and not behind it or knotted up in the way it is threaded
pull on the needle thread and it should move with a steady pull not very hard
if it is not moving fairly easily the check how you have the thread installed
also old thread will break easily as the bonding used to keep the strands together breaks down and is difficult for the thread to slide though the needle
another point is the needle to hook timing and the clearance there as well .
if there is a problem there , the hook will split the thread from the needle and break it
if you still have problems , take it to a sewing machine service center ( any one ) and they will advise of the problem and show you how to fix it

I will make this easy first always thread the machine upper looper then lower looper then the needles if a thread breaks especially if it was one of the loopers, make sure to pull the needle thread out before hand then rethread. as for the breakages look to see if the loopers are hitting each other when they cross and see if the needles are hitting the loopers when they go together either of these things will cause problems if so it will need to be looked at by a tech

Rethread the machine following these directions:
all machines thread the same. TTN tension, take up,
needle.
Beginning with the spool, guide the
thread through the thread guides to the tension assembly. Pull the thread
through the tension assembly and test it to make sure the tension is working
correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or
something in the middle. Raise the presser foot and pull the thread through the
tension. It should pull easily!! Lower the presser foot and pull the thread. It
should pull noticeably harder.) If it passes this test, continue up through the
take up lever,then down through the thread guides to the needle. Make sure your
needle is fully inserted and turned the correct way.( If you load your bobbin
case from the left side,the needle rule is normally FLAT to the RIGHT is RIGHT.
There are some exceptions. If you have a newer style drop in bobbin or your
bobbin case loads in the front then the rule is FLAT to the BACK.
Remove the bobbin case and bobbin. Pull on the bobbin thread to make sure it doesn't pull too hard. It should have some tension on it but not a lot. Insert the bobbin and bobbin case into the hook assembly and pull on the bobbin thread again.The tension should still be about the same. If it is tight, you need to look at the bottom of the pin that the bobbin case sits on and see if there are any threads looped around it. If there are , you need to remove them.
Hold the top thread , turn the hand wheel and see if the thread is catching someplace around the hook assembly. If it pulls the thread up easily, put some fabric in it and see how it works.
Make sure the thread is through the take up lever.

if thread is good quality you may have a sharp groove in your needle plate hole from needle breakage. if so, polish with emery tape.

Hi, I'm guessing you have the bobbin in the bobbincase upside down and its turning the wrong way. Or the machine is not thread correctly. Possibly there is junk in between the tension discs at the top that the thread goes between. Just some thoughts.
