Cannot get upper thread tension right-thread bunches up under fabric

SOURCE: sudden knotting under fabric

I have an Elna 2005 machine and had a similar but opposite problem whereby the tension up top was too tight - thread wouldn't pull smoothly. I found adjusting the feed dog lever slightly helped the stitches a lot, even though the needle tension up top is no better. Hope that helps! :-s

I had this problem and it all came down to using the wrong backing. I kep trying to use tearaway on everything but WRONG. Using the proper backing corrects most problems. Good Luck!

Try taking out your bobbin and upper thread and rethread and check tension. Thread may be caught down below or lint.

Needle in correct? Be sure your bobbin is not in upside down and turning the wrong way. Possibly the hook that the bobbicase fits in/on has been hit by a needle and caused a burr that is catching the thread as it comes around. The burr would have to be polished off or hook replaced. The machine could be slightly out of time also.

If you are having problems with the thread on the underside of the fabric, that is usually the upper tension. Check to make sure that it is threaded correctly. If so, make sure that the thread is inside the tension disc and that there are no pieces of thread caught in the tension. If it is threaded and there are no thread caught up in the tension assembly, adjust your tension dial to a slightly higher number. Do this until you get a good stitch.
