The upper thread is constantly breaking. What is wrong?

If the display reads "Check and rethread upper thread", follow the steps below to resolve the issue:
1. Upper thread may be broken.
2. Upper thread may be caught on the spool on top of the machine.
3. Upper thread spool may have run out of thread.
4. Replace the needle in the machine with a new needle.
5. Your needle could be bent or burred causing the thread to break.
6. Check that you are using the correct size thread.
- If embroidering, use 40/50 machine embroidery thread on top and 60 weight in bobbin only.
Turn your machine off and rethread the machine from the start.

Here is the Manual see page 41 for trouble shooting

Pages 9 to 14 to ensure correct thread procedure

and check pages 17, 18 re correct thread tension

and make sure you have folled maintence guidlines on page 40

Totally remove the upper thread from the machine then rethread. When threading the top thread, ALWAYS RAISE the presser foot so the thread will seat properly in the tension disk. The thread is probably breaking because the tension is too tight. Try setting it at the midway point and then tweak it from there. Also check that the thread path is correct--incorrect threading could cause extra tension on the thread.

In case there is gunk build-up in the tension disk, you can moisten a piece of perl cotton thread with rubbing alcohol, loosen the tension disk all the way, Raise the presser foot and then, gently, pull the perl cotton Down through the tension disk a couple of times. (Always pull Down, Never Up!)

If you continue to have problems, you may need to take it for service.

Be sure to RAISE the presser foot BEFORE threading the upper thread. This releases the tension disk so the thread can seat properly. If upper thread is breaking soon after beginning to sew, it usually is because the upper tension is too tight. Try loosening it and re-testing. The upper and lower threads should meet in the middle of the fabric.

Check the tension for upper thread and bobbin(tiny screw to turn anticlockwise to give less tension)

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

the needle thread tension is wrong
bunching up under the material indicates that it is too loose

I had the same problem with the blue thread- it would sew and inch then pop- mine worked wihtout breaking after I re threaded in this order: green, blue, red then yellow

When the thread breaks too often, try these, that goes for all sewing machines
1. Replace the needles,
2. Loosen slightly the tension of the needle threads.
3. The top threads are to thin,
4.The sewing (rotary) hook or looper, has burs,
5. Wrong threading

If you have not oiled your machine then it is best you do so, the machine is dry.or make checks on your bobin case it could be bend or needs to be ajdust.or worn out.good luck.
