When i start to sew, my thread gets caught up on bobbin. the string gets wrapped around the bobbin then breaks the thread. it seems as though the bobbin is sitting a hair too high. ? ? ?

Sounds like there could be a burr or nick somewhere that is catching the thread and shredding it. Change the needle. Wrap your index finger with some fine fabric (old hosiery, chiffon, silk) and run it around inside the machine around the bobbin/shuttle, feed dogs, needleplate, presser foot. If there is a burr, you will probably find it. If it is minor, it can be smoothed with a fine emery board or fine sand paper. If it is major, you may need to replace the part.

There may be thread caught in the bobbin area which is not allowing the hand wheel to turn. Remove the bobbin case and check the hook for threads wrapped around the spindle and/or caught in the hook mechanism. A little clear sewing machine oil in a pipe cleaner is sometimes helpful in freeing threads in this area.

It sounds like the lower shuttle is out of place. You should be able to take out the bobbin case and unlatch the shuttle. It will probably be in 2 pieces. Clean out the dust behind it and replace the shuttle pieces. You may have to fiddle with it a little to get them back in place. Then you can test it by manually turning the wheel. Make sure the bobbin is placed into the bobbin case and that the bobbin turns in the direction that you pull the thread.

Good luck.

these are suggestion, if they don't help then the machine needs to be checked at a sewing machine shop
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


7. The thread is either to heavy or to fine for the needle


8. Try a different spool or cone of thread

Readjust the needle timing and check the thread tensions top and bottom.

Hello Crystal, I also have had problems in the past with drop-in bobbins . I had to experiment with different model bobbins . The cause I found was due to the bobbin was not tall enough in the drop-in bobbin case. When sewing , the bobbin would rock in the bobbin case and the top thread would get caught on the bobbin instead of going over the top of the bobbin, causing the rats nest that you described. I would recommend finding a taller bobbin to fit in the bobbin case. There are about five different bobbins that will fit in there, but only one that will work properly. Knowing the exact model number of your machine would be a great help to finding the correct bobbin.

Try inserting the bobbin in the reverse direction. Most machines take a bobbin clockwise or counterclockwise and it can make a difference. Also try a new needle, a bad needle is often the problem believe it or not.

The top little circle you think you're supposed to wrap your string around - the one that you wrap the thread around to fill the bobbin -- thats not what you're supposed to wrap it around. Im an idiot, and thats what I was using. My friend Amanda showed me what I did wrong.. LOL

Is it birdnesting under the bottom or it is actually getting tangled inside the bobbin case? I've had my machine for almost a year and don't think I've had your exact issue. Sometimes, when you do a stich over a already stitched portion, you may have a problem with the bobbin and I just generally stop and start it again. It is important that you use the correct needle and also use a good embroidery thread and stablizer. Another thing suggested is changing the needle after about every 5 designs. Also, check the bobbin case to make sure there's no fuzzies caught in it. I use "canned air" like you use on computer keyboards. I also only use 40 weight emboidery thread for the top and actual bobbin thread for the bottom. Other threads can really jam everything up. So it's been trial and error to find the right combinations. Good Luck!

you need to replace your shukle that holds the tread bobbing below.it is either slack or broken . if it is slack then you tighten the little screw that holds a cover that gives the thread tension .if its broken then replace it.once the thread is slack below it will cause your thread to bundle up.
