Sometimes my machine will simply stop embroidering and report an error: Check is thread is broken. Check if needle is bent. The thread isn't broken, and the needle isn't bent. I just had the machine professionally serviced, and of course it worked beautifully for the mechanic. What can I do?

If the display reads "Check and rethread upper thread", follow the steps below to resolve the issue:
1. Upper thread may be broken.
2. Upper thread may be caught on the spool on top of the machine.
3. Upper thread spool may have run out of thread.
4. Replace the needle in the machine with a new needle.
5. Your needle could be bent or burred causing the thread to break.
6. Check that you are using the correct size thread.
- If embroidering, use 40/50 machine embroidery thread on top and 60 weight in bobbin only. Turn your machine off and rethread the machine from the start.
Time to take it in and have the repair tech service & clean upper tension assembly. When you clip/ change threads be sure not to pull the thread back out of tension assembly. Snip thread at spool, raise foot to release tension and then pull the short thread out from the needle. The Automatic tension is very delicate and pulling thread out backwards can cause thread/lint build up and problems like your having. Sal the Sewing Gal
Turn the machine off. Check for a broken or bent needle or a bird's nest in the bobbin area. Sometimes when I try to put an extra heavy piece through the machine I' ll get that message. The most common reason for the error is a broken or bent needle.
The noise is because the machine is trying to raise or lower a needle and can't move. Several things to check. Did the needle break and jam in the bottom thread? Is the needle bent or jam? Did the thread jam in the bobbin area? I had a 'knot' of thread build up on the bottom and it hooked itself into the metal clip on the bobbin so that the needle couldn't raise. If thread jams in the bottom carefully cut the threads until you can free the hoop and material. Then check to make sure all pieces of thread and fuzz has been removed in the bobbin case. If it happens again check to see if the bobbin case or the throat plate is scratched or bent. If you are stitching Free Standing Lace on this machine or a piece with over 20,000 stitches I recommend starting with a new full bobbin and a new needle. As you get toward the bottom of the bobbin, thread seems to have a high likelihood of tangling or looping.
sometimes when a needle gets bent, it can cause the sewing machine to need a adjustment by a technican. sometimes a jam can be caused by the thread coming off the thread take up lever or the bobbin is turned the wrong way in the bobbin case or the bobbin was not thread correctly
try a new needle try a new bobbin--make sure the bobbin is turned the right way in the bobbin case check under the needle plate and in the feed dog area for thread it could also be a problem with the motherboard.
1.check the needle & see if it's bent--if so replace
2.lay the needle on a flat surface & roll the needle over if it doesn't roll true replace
3.check for blunt needle-if needle makes a popping sound when needle penetrates fabric
4.needle is not all way up in holder
on my mechanical sewing machine sometimes the threads come off the take up lever, that causes the thread to bunch up under something I'm working on
also check thread in bobbin
