Needle thread is missing the bobbin catcher

increase the needle thread tension up a bit as it is too loose to pull the bobbin thread up properly
keep adjusting until both threads are at the middle of the materials being sewn

Install a brand new needle.

Check the upper tension: Remove the thread. RAISE the presser foot and rethread from the beginning. This ensures the thread is seated properly in the tension disk. Make sure the bobbin case is threaded properly.

If still missing the bobbin thread, it probably has a needle/hook timing issue.

Likely a tiny crack after overtightening

try a new needle

keep a check on the thread take up lever that the thread doesn't come off of it

rethread the machine to make sure that the thread isn't catching on anything

clean under the needle plate for loose thread or lint & in the bobbin area also

make sure the bobbin is inserted correctly

start by removing the bobbin, and reinstalling, make sure the thread runs through the bobin tension plate, the little plate that puts pressure on bobbin thread to keep it tight, also look at thread and needle, if thread insn't thread through the needle, it won't catch, feelfree to call me if you need better help, devin 239-895-4845, Quality Auto Trim Inc 239-849-0015

Check that it is threaded correctly (both top and bottom) making sure that the upper thread is in the takeup lever. Watch the needle as you slowly turn the handwheel counter clockwise (toward you) and the needle point touches the fabric (make sure presser foot is down). Is the thread still relatively taunt? If it is loose, the upper thread tension unit does not have enough tension. Check the areas where the thread goes and make sure you remove any loose threads or fluff which could be inhibiting the tension discs from closing over the thread. If the tension unit still is not tightening enough, the tension unit may need to be replaced or the circuit board replaced. If everything is ok in the upper thread area, now look at the bobbin area. With no fabric, watch as the needle enters the bobbin area. Does it go down and the upper thread catch the bobbin thread and pulls it to the surface? Check for anything preventing the bobbin thread from being pulled up to the surface through the needle plate.

Hello,
Here are some things to try.

If it's Your upper thread breaking:

* Rethread your machine
An incorrectly threaded machine can cause thread to break.

* Decrease the tension on your machine
The tension may be too tight for your thread.

* Reposition the spool of thread on the spindle
You know that little nick in the edge of a spool that’s used to hold the loose end of the thread? Your thread may be catching on this nick as you sew. Place your spool so that this nick rests against the bottom of the spindle.

* Reinsert your needle
Make sure it goes all the way into the holder and that it’s positioned correctly, usually with the flat side away from the bobbin, but consult your machine’s manual to be sure.

* Change your needle
Your needle may be bent or dull. The eye of your needle may have a nick in it that’s cutting the thread as you sew. Or your needle may be too small for the thread you’re using, in which case, change to a larger needle. And make sure your needle is appropriate for the weight and type of your fabric.

* Change your thread
Your thread may be weak. Or your thread may be fuzzy and irregular, causing it to catch in the eye of your needle as you sew. Cheap thread tends to be weak and fuzzy, so make sure to
use a quality, brand name thread. And if you’ve been sewing with an older cotton thread, which can dry out and become brittle with age, try a newer thread.

* Check your presser foot for damage to the needle hole
A burr in your presser foot’s needle hole may be cutting your thread. Gently smooth any rough spot you find with an emery cloth.


* There may be a burr in one of your thread guides, in which case, you may need to have your
machine professionally serviced to have the part replaced.


If it's Your lower thread breaking:

* Reinsert your bobbin
Your bobbin may not be seated properly in its case.

* Rethread your bobbin
Your bobbin may be threaded incorrectly or the thread may be tangled.

* Remove some of the thread from your bobbin
If your bobbin is very full (if it’s hard to insert into the case, it’s too full), this may be keeping your bobbin from turning smoothly.

* Rewind your bobbin thread
If your bobbin thread is wound unevenly, this may be keeping your bobbin from turning
smoothly.

* Try a new bobbin
There could be a nick along the edge of your bobbin spool that’s catching your thread as you sew.

* Clean the lint from your bobbin case
Lint in your bobbin case could be keeping your bobbin from working properly.

* Check the needle hole in your throat plate for rough spots
A burr in the needle hole of your throat plate, usually caused by the needle hitting the throat plate, could be cutting your thread. Gently smooth any rough spot you find with an emery cloth.

I hope one of these solutions work for you.

check that the needle is in the right way round i.e. with cut out on the needle facing into the machine. if this is fine then check that as the needle comes back up from the lowest point that it goes to, that the point on the bobbin case passes just above the hole in the needle, i.e. in the middle of the cut out.(if not it needs re timing) if threaded a small loop should appear at this point for the bottom bobbin to catch if not slacken the top thread and try again.

Check the timing of the needle to the hook.
Here is a guide to generic principles of Timing

sounds like your keeping the upper thread too tight when you drop your needle down to catch the bobbin or the bobbin thread that you left hang out is too short, let me know if it works amy
