How to Troubleshoot Bobbin Problems Sewing Machine

The needle thread breaks
1. The needle thread is not threaded properly
2. The needle thread tension is too tight
3.the needle is bent or blunt
4. The needle is incorrectly inserted into the needle holder
5. The needle thread and the bobbin thread are not set under the presser foot when starting sewing
6. The threads were not drawn to the rear after sewing
7. The thread is either too heavy or too fine for the needle
Bobbin thread breaks
1. The bobbin thread is not threaded properly in the bobbin holder
2. Lint has collected in the bobbin holder
3. The bobbin is damaged and doesn't turn smoothly

1. Using a doubled piece of fabric similar to what you have in mind for your project, sew a seam on the diagonal-pulling the fabric on the diagonal to break the threads. (Ideal tension would either break neither thread or break both threads. So, a single breaking thread signals that the tension needs adjusting.)
2. Snap out the faceplate to remove it & to gain access the bobbin area below the sewing needle.
3. Remove the bobbin case & bobbin-lifting the hinged latch that you would to wind a new bobbin-leaving the bobbin in the case. (You need it in there to feel the tension as you adjust it.)
4. Using a small screwdriver, very slightly turn the screw on the side of the bobbin case clockwise to increase tension; counterclockwise to decrease tension.
5. Pull the bobbin thread while you hold the bobbin in its case & feel the thread's tension. Too tight of tension would prevent the thread from dispensing (& possibly break), but too loose of tension would allow the bobbin to fall out of its case.
6. Return the bobbin case to the sewing machine & close the faceplate.
7. Repeat this whole routine from Step One on the doubled fabric. Stitching should run along both the top & the bottom in the same way-locking in the center. A diagonal pull of the fabric should show which thread(s) break(s). Repeat Steps Two through Four to only adjust the screw aside the bobbin case in order to allow the threads to lock in the center of the fabric with both threads having the same break or no-break result.

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

Bobbin thread breaks


1. There is a right way & wrong way to insert the bobbin in the case --when you insert the bobbin in if it doesn't stitch correctly turn the bobbin over see if that helps or bobbin case is not inserted correctly


2. Lint has collected in the bobbin holder


3. The bobbin is damaged & doesn't turn smoothly


4. Lower thread tension is two tight

if the sewing machine has a top loading bobbin, you may have to have the sewing machine checked to see if there is something wrong with the bobbin case or the hook and hook race.
I suggest try a new needle--one for the fabric being sewed
also try another bobbin
rethread the sewing machine top and bobbin, using every thread guide.
