Brother pe-770 upper thread breaks after the needle broke

The needle broke, so replaced and such. The problem that won't go away is the upper thread continues to break after 10 stitches. it looks like it breaks at the needle or before set 5 of threading. the thread is fraded or unraveled.

    Is it possible that the size of the stitch is causing a problem? I am using files I created myself and the stitch size is extremely small.

  • it would be a good idea to increase the stitch size, but even if the stitch size is still small the thread should not break. is the thread and needle compatable with each other? the thread should move smoothly thru the needle. also check the tension to make sure it's not to tight. make sure the thread is not wrapping around the spool pin. also sometimes when a needle breaks that can cause the needle bar to need adjusting, so if the problem persists it would be a good idea to have the machine checked to see if the needle bar is out of time...

Try changing the needle again, sometimes even new needle can be damaged
also check for burrs around the needle plate

When your needle broke the first time, it may have gouge or cause sharp edges to appear on the faceplate or the bottom thread catcher hook. You need to smooth these scratched surface out with very fine sand paper or a dremel with a wire brush.

My pe 770 brother machine. Why is it that the thread breaks all the time I want to use it

Usually misthreading, however, it could also be something else, ie needle, old or bargain bin thread, tension, burr or snag.

Why is my thread breaking

My Brother PE 770 will work for about a minute then the upper thread will get so tight that it will break. How do I fix this?

Check that the thread has not wrapped around the thread spool pin or one of the thread guides. Something is holding the thread from unwinding from the thread spool. Old style thread spools also have the small slit to hold the thread tail which will tend to catch the thread (turn the spool over). Sounds like the symptoms I've experienced with this problem.

Troubleshooting Brother PE 770

Usually this is a tension problem. On mechanical machines, you'd adjust the dial, or possibly even the bobbin tension. But on a computer machine, I don't know how you set the upper tension, sorry to say.

Sometimes it can help to unthread and rethread a machine, and I don't know why it sometimes works, but it's a simple thing to try.

But if the upper tension isn't set correctly for the work being done or if the tension mechanism, however that's handled on a computer machine, isn't working correctly, this is what happens. Bird's nest is a good way to describe it.

Sometimes lint built up in the bobbin case can cause this symptom too, but I'd assume you keep this area clean. One reason I haven't yet invested in a computer machine is because problems like this often don't have such simple solutions as on the mechanical machines.

I'm using Brother Poly thread on my Brother PE-770. Everything was fine until I changed needles. I followed the directions exactly. But now, when I embroider, my thread keeps unraveling and the needle...

Please check your needle position, putting it in backwards is a very common error, the FLAT side of the needle shank should be towards the back. Also be sure that during the transition, that the bobbin thread did not get misaligned.
So, make sure the needle has the flat side to the back, and rethread your bobbin thread through making sure it is correct.

Automatic needle threader won't work on brother pe-770

Always make sure the hand wheel is at the exact top. Have you replaced the need recently? If it's bent, then the threader will not work. If the needle is loose or not all the way to the top in the holder, it will also cause the threader to not work.

Thread breaking, not even threaded in needle anymore, thread gets caught on spool sometimes

Upper thread breaks
1.the needle may be bent or damaged--try rolling the needle on a flat surface to see if it's bent or not
Or the needle could be in backwards
Correct needle insertion
Correct needle insertion is mandatory for proper use of sewing machine.
Raise the needle bar to the highest point, then loosen the clamp screw to remove the old needle, place the new needle in the clamp with the flat side to the back of the machine or if using a round needle--the groove in the needle should face away from the shaft.
Push the needle all the way up to the stop or as far as it will go, then tighten the needle clamp screw
2.upper tension may be to tight--try 3 to 5
3.thread may be hanging up in bobbin case--check area for loose threads or lint
Lower thread breaks
The most probable cause of lower thread breaking is improperly wound bobbin
1.always start with a empty bobbin
Never wind one color over the other
2.choose thread that is identical in color & type as the one to be used for upper threading
3.wind the bobbin evenly across & in layers
4.don't wind the bobbin so full that it would be tight & hard to insert into bobbin case
5.bent bobbin--replace
6.lint built up in the bobbin case--frequent cleanings will eliminate this problem, the more often you use the sewing machine the more often it needs to be cleaned
7.thread catching on the bobbin spring or latch on bobbin case, check to see that the bobbin is inserted completely & correctly, & that you are using the right kind of bobbin

for the top & bobbin thread keep thread tails of 3 to 6 inches long pulled behind the needle before you start sewing

yes,sometimes the thread will get caught on the spool, you might think about getting a extra holder that sets behind the machine to hold those spool's that the thread get caught on, that's what I did.

I have a brother pe 770 and the bobbin will not catch the thread. The thread will wrapped and tangled up around the bobbin case and bobbin, but will not catch the bobbin at all. I chcked the needle, it is...

You need to sew the first stitch slowly. Lower the needle by hand and take up carefully. Pull the needle thread up and the bobbin thread should be caught in the formed loop and come with it. Pull them both to the back of the machine and sew.

Brother pe150 won't pick up bobbin thread

Hi. This may sound silly, but the most likely reason the upper thread doesn't pick up the bobbin thread is that the needle is in backwards. (Sounds silly, but it's true!)

Needle shanks have a flat side and that flat side has to go in a particular way for your machine. With most modern machines, the flat side goes to the rear, facing away from you. Check your manual to be sure.

The second most likely reason is that your needle may be bent. Check that your needle is straight (or just use a new one).

Hope this helps!

Happy Sewing,

Brother PE-150V bobbin thread

For embroidery, and zig-zag, and because the needle makes side movements, it needs more needle thread.
So try to keep you needle thread not very tight,
and tight up your bobbin case tension more, so that the two threads meet under the meterial.
