    I have the same problem. However, the machine has an automatic threader, so how can it be done differently? Also I am making sure the pressor foot is up when threading. What can I do??? At the moment I have the tension on 0 and it is not good still. It seemed to happen quickly with change of thread.

    Neither of these suggestions have helped. The problem also comes and goes. sometimes just changing the thread brand fixes the problem however I am using the threads recommended at the store. Does anyone know of a brand of thread i should use for this machine? Or any further suggestions would be appreciated.

Upper thread keeps braking


Usually thread breakage is a result of incorrect threading or the thread tension set too tight.

Install a brand new needle.

Remove the upper thread. RAISE the presser foot and rethread from the beginning (verify the threading sequence is correct).

Check that the tension is set at the midway point between the high and low numbers.

Retest. If still breaking, there are other less common problems (thread/needle incompatibility, burrs or knicks catching the thread, etc) that may be the cause. Check the following web sites:

Brother pc 8500 upper thread breaks


Check the spindle the thread is mounted on and see if it\'s wrapped around it. Sometimes thread will catch and wrap around the spool spindle and break.

Check thread guides to be sure there are no nicks that might be catching the thread or damaging it.



Replace the needle.. a burr in the eye can cause upper thread to break. Needles should be replaced often, modern fibres can be hard on them, they get dull and that\'s no help for anything either.



Make sure the thread spool is mounted on the spindle with the thread coming off as directed in the manual. Some machines only work when the thread feeds in the right direction from the spool.



It can also be a tension issue.. tight upper tension or tight bobbin tension. Bobbin tension may be adjustable manually, but it\'s pretty rare for it be a problem. Upper tension, I don\'t know. I\'ve yet to get into computer machines so am not familiar with how they set upper tension.



But the mechanism that produces the tension can wear out or break and need replacement.

I have been trying to make a buttonhole but the top thread keeps breaking and the threads are all snarled up underneath the material. what am i doing wrong? i have a brother ls2125 machine maria


Firstly have you interfaced the material that you are buttonholing on? You will never get a good buttonhole otherwise. Also start each new project with a new needle matching the size to the weight of fabric. Good guide available here http://sewing.about.com/od/sewingmachineindex/ig/Sewing-Machine-Needles/

Top thread breaking is usually because the tension is too tight or the thread is catching somewhere in the thread path from the spool to the needle. Also check that the needle doesn't have a burr on it somewhere, or is blunt.

Thread snarls underneath the fabric is usually caused by top thread tension issues. You will need to rethread top and bottom and CHECK that the thread is in tension correctly. So lower the pressure foot and pull the top thread just before the needle - does it feel hard to pull? If not, then the thread is not in tension. Rethread top again, checking the tension dial is set to 5 and the thread is correctly pulled between the tension discs. And always hold the two thread tails at the back of the sewing area as you start each new seam to avoid these being pulled down into the bobbin area and getting jammed up.

So, rethread, test sew and get the top tension sorted, a nice straight stitch happening, then try the buttonholing sequence again.

Bobbin thread keeps knotting


1. Do you mean that there are knots in the bobbin thread?
2. Is the bottom thread in your stitching looping and knotting.

If yes to 1. you need to rewind your bobbin fresh, and keep slight tension on the thread reel that you are winding it from. Put the handle of your scissors into the top of the reel to apply a gentle pressure while winding. Keep your eye on the bobbin as it winds and give it a nudge with a finger tip to ensure it winds the bobbin evenly top, middle and bottom.

If yes to 2, then you need to check your bobbin threading, is the thread even under tension. Is the bobbin tension set correctly. Break out your manual and revisit this to ensure it is set correctly.

Thread is catching & breaking somewhere inside the machine before it gets to the needle. brother XL-5600 machine


According to page 18 of the manual, the only place the thread could be catching would be the tension discs or the uptake lever.

Lift the presser foot and run a heavier thread or flat, unwaxed dental floss through the threading procedure to see if this will clean out a thread that may have jammed into the discs.

Always thread with the presser foot up and make sure the uptake lever catches the thread.

If this continues, take the machine to an authorized Brother dealer for service.

Bobbin holder keeps catchin thread


Try re-threading, make sure the presser lifer is up so the tension discs are open and the thread will go into them. It sounds like you may have missed either the upper tension discs or the take up lever.

A drop of oil on the hook wouldn't hurt if you haven't oiled in awhile.

good luck!

My brother 2125I sewing machine bottom thread keeps breaking


You may be sewing too fast, using cheap thread or your tension is off. All of which can cause your bobbin thread to break.
