Bobbin thread How do I thread the bobin

The bobin may not be in correctly. When looking at the bobin, with the thread threaded through the bobbin case, make sure that it spins counter clockwise. Also the problem could be caused by the machine not threaded correctly. But it is more likely the bobbin case and bobbin

Make sure your bobbin is inserted into the case spinning in the correct direction.

With out looking at the machine it is hard to determine the exact problem, but make sure your bobbin thread is placed in the bobbine case corretly, and pulled through the little tension area on the bobbin case.

Next make sure the upper thread is in the tension discs, if not this can also cause you a problem, plus if possible used a little canned air (with the pressure foot up, machine unplugged and thread removed) blow out the tension area.

Good luck.

When loading the bobbin there is most likely not enough tension on the thread letting it overlap incorrectly. Try wrapping thread around a tensioner when filling and that should help. That way the bobbin is rolled as tight as the tension on the upper thread when sewing.

Make sure thye top tension is about 4 or 5, tighten the bobbin tension screw on the bobbin case about a quarter of a turn at a time clockwise and test until you get it right

change the needle, if bent it may skip, use top thread while holding to pull thru, turn bobin around to turn in oposite dirrection, bobins usually turn in 1 correct dirrection

If there is a screw on the side of bobbin case try tightening it up.This usually worked on my old machine.

lower your top tension down, as it is tighter then your bobbin thread and also tighten your bobbin thread, this is done by the small screw on the bobbin holder, also you can try using the older metal bobbins these are the ones with the small holes around the top and bottom shank, but please make sure that they are the larger size bobbin, and only go very slow at first, try just in sewing mode first or just wind it over by hand.

i think your putting in your bobin backwards,
to check put your bobin in and hold bobin , and bobin case by thread if it unrolls its backwards,
hope this helps!!

I have the same problem, I fix it by removing both Shuttle hook and Bobbin Case and tested it to see if the shuttle hook rotated freely within bobbin case. I noticed the screw for the tension spring was too high and was rubbing agaist bobbin case. Just tighten screw on spring and and recheck for rubbing.
