Most likely, your tension is too tight. First thing, unthread the machine. RAISE the presser foot and rethread from the beginning. The standard initial tension setting is the midway point between high & low number, HOWEVER, that will probably need to be tweaked as machines vary.

The tension is correct when upper and bobbin threads meet in the middle of the fabric. If the thread continues to break, then there may be a snag somewhere that is catching the thread and breaking it. Also, check that the thread notch on the spool is not catching the thread. Be sure your needle is compatible with the thread, ie the thread is too thick for the needle eye.

Upper thread keeps breaking

The most common cause of upper thread breakage is incorrect threading. Remove all the thread, install a brand new needle, RAISE the presser foot, and then rethread from the beginning. (Verify with the owner's manual that the threading process is correct.) The other thing to check is the upper tension setting. The factory standard setting is usually the halfway point between the high and low numbers. Tweak the upper tension to achieve correct tension. Correct tension is when the upper thread and bobbin thread meet in the middle of the fabric. The upper tension is meant to be the most common method of tweaking tension. As such, a sewist should become comfortable with tweaking the upper tension.

I can't get the tension right. The stitches on the top side are too loose and the thread just pulls out.

loosen the needle thread tension of a bit
sew on a scrap bit of material until you get the tensions right
correct tension is when the bottom thread and the top thread meet at the join of the two pieces being sewn
you will only need to sew 1" to see how it is going

The needle thread keeps breaking, I'm using good quality thread and have tried re threading and changing the needle but it still keeps breaking, any advice would be most welcome.

1. Set the tension on the bobbin.
2. When you thread the upper thread do it with the pressure foot up.
While you are threading give slight tugs to check for snags. If there are snugs you must fix them.
3. Put the pressure foot down and adjust the tension to four. Give a tug. It should have tension but still allow the thread to flow.
(Look at your thread and look for fuzz on the sides. This indicates a bad quality thread. A good choice is embroidery.)
4. Make sure the needle has been installed going the right direction. Usually flat to the front or to the right side.
5. Turn the hand wheel while you hold the needle thread to the front.
The bobbin thread should come above the throat plate in about one turn.

My top thread keeps snapping on my consew 118. There are loops on the underside when I stitch with it and the thread keeps snapping at the needle. It is threaded right but it keeps happening literally...

The top thread breaks
1. the needle thread is not threaded properly
2. The needle thread tension is to tight
3. The needle is bent or blunt
4. The needle is incorrectly inserted
5. The needle thread & the bobbin thread are not set under the presser foot when starting to sew
6. the threads were not drawn to the rear after sewing
7. The thread is either to heavy or to fine for the needle
8. Try a different spool or cone of thread

Thread looping on the bottom of your fabric can be caused by little or no top tension or too much bobbin tension. Another cause is thread or lint caught in the top tension.
Make sure the thread is between the tension discs and that no thread or lint is caught

Bottom thread is loose and loopy, have tried new needle, thread, cleaned out bottom, tension adjusted.....nothing works, can you help. I see many others have same problem but i cannot see an answer

When your bottom thread is loopy it means that the UPPER thread is not properly threaded. First make sure your needle has the flat side to the back of the machine and that it's the right size needle for your machine and the fabric you're using. You probably missed the tension discs when you threaded the upper thread. Make sure that your presser foot is up and that your needle is in the uppermost position. Try re-threading it and when you get to the tension discs pull the thread back and forth so you hear a little snap. That tells you that your thread is being placed in the discs correctly. (This also cleans out your tension discs in case there's lint in them.) Make sure that you tension dial is on about #4. Finish threading and you should be good to go. Thanks for using FixYa!

Thread keeps snapping - Brother JS 23

Try adjusting your tension. I had this same problem and then I adjusted the tension of my thread for each project I was sewing and it solved the issue.

Brother LS-2125 Upper Thread Snapping

I had the same problem and it was so frustrating! It was happening to me because I wasn't using the right size needle. Go up a couple of needle sizes and see if that helps.
