Thread pops out of needle

When it stitches, does appear the top thread is tighter and pulling the bobbin thread up? Pay attention to what is happening before the thread breaks. Sew slowly and manually turn the handwheel. Where does it break? What are the symptoms before it breaks? Does it fray/shred at the needle eye? (The thread is not advancing through the needle eye properly and is actually being shredded, could be the needle has a sharp spot or the needle eye is too small for the thread. Coarse fabric will also shred thread.) Do you notice the top thread getting tighter and tighter and then finally popping? (The thread is being held back somewhere in the thread path {misthreading'--happens to me when it gets wrapped around the spool pin or a thread guide.)

Suggest removing the top thread completely from the machine. Install a brand new needle that is the appropriate size and type for the thread and fabric. Remember to ALWAYS RAISE the presser foot and rethread from the beginning. Verify the thread path is correct. Adjust the top tension until the top and bobbin threads meet in the middle of the fabric.

Why is my thread breaking

First, install a brand new needle. Verify that it is the correct needle and needle eye size for the thread and fabric you are sewing. (Change needles frequently. Needles are the most inexpensive sewing accessory and most the most common repair for a malfunctioning sewing machine.)

What you are experiencing sounds like the thread is shredding at the needle eye and eventually breaking. Sometimes, a top stitch needle will work better because the groove in the back of the needle shields the thread better as the needle pierces the fabric multiple times. A piece of thread can pierce the fabric over a dozen times before it forms a stitch, so friction and rough fabric will take its toll.

All About Needles

Use only good quality threads--AVOID old thread and bargain bin threads. They are cheap and there is a reason why they are--because what they make up for in price is paid in frustration!!!! Polyester thread used to be the bane of sewing machines, but polyester thread has greatly improved and is now a favorite for experienced sewists. It is thin and strong. Threads that are fuzzy (cotton-wrapped polyester of old Coats & Clark variety) threads are not the best for your machine or project. Check out better quality threads, ie Gutermann, Superior, Sulky, Aurfil, Isacord, and multiple other brands. Make sure you are buying the correct type of thread for your project--don't use embroidery thread to sew your garment unless you want the seams to pop open while you're wearing it.

Remove the thread from your machine. ALWAYS RAISE the presser foot and then rethread from the beginning. The raised presser foot releases the tension disk so the thread will seat properly.

Check that the upper tension is set somewhere around the midway point. This is a factory standard although most machines may require some adjustments. Test the stitch on your fabric. The tension is ideal when both upper and bobbin threads meet in the middle of the fabric. If the bobbin thread shows on top of the fabric, the upper tension is too tight. If the upper thread shows on the underside of the fabric, the upper tension is too loose.

If the thread is still shredding, then there's a likelihood there is a burr or nick somewhere on the needleplate or in the bobbin/hook area. If you wrap your index finger with fine fabric (like old hosiery) and rub you finger around, you may find the burr. If it is small, you can lightly smooth it with a fine emery board. If it is a large one, you may need to replace the part.

Have you tried loosening the upper tension? Remove the upper thread, RAISE the presser foot and rethread from the beginning (make sure it follows the correct thread pathway). Sometimes the upper thread jumps out of a thread guide or wraps around something. Or try a different brand of thread? Avoid old or bargain bin threads--use good quality thread. Could also be the incorrect needle for the thread/fabric, ie thread too large for the needle eye.

Sewing Machine Thread Keeps Breaking

NMSU Checklist of Common Machine Troubles

Why Does My Thread Keep Breaking While Sew

...

here's my suggestions
change the needle-make sure the needle is inserted correctly
into the needle holder & also turned the right way
make sure when sewing on the machine that the top thread does
not come off the thread take up lever
check the top thread tension it may be too tight,, usually 4 is good
or if the machine has automatic tension set it there
make sure it's the right needle for the machine & make sure it's the
right needle for the fabric & thread.
some thread is knotty ,,, make sure the thread is good quality

make thread tails 4 to 6 inches long & pull them behind the needle before you start to sew, & you should not have any more problems, that's what I do before I sew.

Bunching of thread is 99% a top tension problem. Make sure you thread the top thread correctly. Thread the machine with the presser lever up. Test the tension by lowering the presser lever before threading the eye of the needle, by pulling the thread with your left hand and adjusting the tension with your right hand while slowly pulling downwards. There should be no resistance when the tension dial is on zero, and you should be able to feel more resistance when you increase the tension. Ideal tension is between 3 and 5. When your top tension is correct, your machine should operate correctly. If you feel no resistance with the presser foot down and the tension dial on 5, check the tension disks for fluff or broken thread. When you lift the presser foot, the tension disks should open and you would be able to remove any cotton or fluff. Good Luck

that use to happen to me on my sewing machines, I would rethread the machine to make sure the thread is not caught on anything like the thread spool, or around anyone of the thread guides

also for both top & bottom threads, I keep a thread tail of 3 to 6 inches & before I start sewing I pull the thread behind the needle to the back of the machine & the I put the fabric under the foot & start sewing & now I don't have that problem anymore

have you checked to see if the needle is bent-lay the needle on a flat surface & roll the needle over,, if the needle does not roll good -replace
blunt needle-if the needle makes a popping sound when the needle penetrates the fabric,,the needle is blunt-replace
sometimes if the thread comes off the thread take-up lever it can jam the thread in the bobbin area
try rethreading the machine
check to make sure the thread isn't wrapping around the spool pin
check the spool of thread to see if the notch on the spool is catching the top thread
check to see if there's a burr on the bobbin case
I hope one of these suggestions helps you
please rate this using the thumbs in upper right hand corner

You should hold the end of the thread coming through the needle until the thread has grasped the bobbin thread.

Maybe the needle isn't in correctly. The flat side of the needle faces right, Also, manual says it will use only Singer Red Band regular point style 2020 size 14 needles. I would think any brand, regular point, size 14 would work.

Threading this dog it not intuitive, and keeping it threaded is a continous task.
Next: Threading
!. Unwinding off spool clockwise --- up from the back through the **** on top . Do NOT wrap thread around tension disc (little round thingy) that is at the ****.

2.On the left end of the knob that looks like a sideways spool there are two silver discs. Slide the thread between them. Make sure it doesn't jump out (at any point during your task)and go one step to the left, between disc and sewing machine. Then down to:

3.Thread straight through 1/4" metal loop at knob-like thread guide. then thread makes a u-shaped trip up the knob-shaped guide to the take-up lever.. Thread tends to slip behind this guide, but needs to stay in the center.

4. Through the take-up lever, right to left, then down to thread guide next to needle, pulls through from back to front then through needle left to right.

OR IT could be the bobbin holder....not even going there right now. Good luck.
