I just got the Brother LX3125 today and the bobbin thread keeps breaking during sewing? What can I try to fix this?

Try a new needle, making sure it is put in properly. A bent needle can break thread. Make sure top tension is set properly.

Things to check for thread breakage (top or bottom)

1. Good thread in the machine - not hand thread, cheap thread, quilting thread.
2. A burr on the hook - a small nick on the hook can grab and tear threads, however this usually causes the top thread to tear, not the bottom
3. Make sure a new needle is in the machine - one made for the material you are sewing
4. The bobbin must be installed to rotate in the correct direction in your bobbin case
5. And I'll say it anyway - tensions - the primary cause of thread breaking - Remember, there are TWO tensions in a sewing machine, top and bottom. Also, the thread you see on the bottom of the stitch is the top thread, and vice-versa.

The top of the machine is not threaded correctly. First raise the presserfot then rethread the machine. Bottom looping is usually caused by a lack of top tension. There could allso be a bur on the hook.

hi there,
pls, the see the figure how bobbibs thread directionhave you seen theres a screw on latch body case of bobins,you can adjust this but mostly this is factory
adjusted,bobbin tension can adjust here.but try to follow the thread direction.set up again the dial setup tension to #3 and stitch to #8 to #12.bobbins slip due to accumulation of thread under
bobbins.hopefully this may help you to continue sewing.
