Question about Sewing Machines
The machine displays E4 which means that thread is tangled or the bobbin was stopped suddenly and there is no sign of either of those problems on my machine.
Try changing the needle
rethread the machine top and bobbin
try a different bobbin
make sure the bobbin is turned the right way in the bobbin case
clean under the needle plate and in the bobbin area for lint
also possible that something has gone wrong with the computer
part of the sewing machine.

SOURCE: bobbin thread tangling up
are you doing embroidery? if so turn off jump stitch cutting if possible. is the machine threaded correctly (pull needle thread out of machine and thread again with presser foot raised.
check for foreign matter in needle tension assembly. ensure there is sufficient needle thread tension.
the thread you see caught up underneath the fabric will be needle thread and indicates insufficient needle thread tension or something preventing the needle thread from being pulled up into the fabric (maybe a damaged bobbin case, or bobbin case position finger, or damaged needle plate hole).

Have you replaced the needle with a new one? Your needle may be bent or in wrong, or the wrong size. You may have a bad needle. Check that the upper thread path is running freely and is not tangled or wrapped around anything. Make sure that the bobbin is unwinding in the correct direction as well, most bobbins, this is clockwise as the bobbin faces you. If you are using inexpensive thread, it could be the thread that is the culprit. Uneven thread in the needle will not flow through the needle properly, and cause bunching as well. Save it for the bobbin, and use good thread in the top.

This could either be due to the bobbin being wound too loosely, or the tension on the top thread is too loose. This just happened to me the other day, and I thought it was the bobbin thread, but then I put another bobbin in with a different color than the top thread (this is a huge help in diagnosing thread issues), and I was surprised to find that it was actually the top thread that was a big loopy mess on the underside of the fabric. I fixed it by tightening the tension on the top thread (quite a bit), and everything was fine.

SOURCE: Jammed thread.
To address my needle thread tangling (horribly) in the bobbin compartment, I rethreaded the bobbin. I cleaned the bobbin and the feeder feet, I changed the bobbin and the thread. I changed the tension on the needle thread and the bobbin thread. NO FIX! Then, I changed the needle - the problem was fixed instantly. I sewed awhile and then put the original needle back in. No problem. I think perhaps that the problem is being caused by the needle getting out of alignment somehow during sewing. If you are having the same issue, try it. It can't hurt!

The top of the machine is not threaded correctly. First raise the presserfot then rethread the machine. Bottom looping is usually caused by a lack of top tension. There could allso be a bur on the hook.
