Try rethreading with a new needle. Make sure presser foot in up position when you rethread. Thread needle with flat side in back and more rounded side facing you. Make sure you pull the thread taut as you insert the thread into all of the tension disks.
Clean out the shuttle and the feed dogs with gentle handling of your small sewing machine lint brush. Sometimes broken thread, lint, and threads from your fabric get caught in these areas and are not visibile until you get the brush bristles in there.
Make sure your top tension is on a medium number and that your pattern setting matches the stitch you wish to perform.Also make sure your needle size matches the fabric weight. Another fix if it isn't anything I have mentioned so far, there is a foot pressure regulator on the left-hand side of your machine which controls the pressure of your presser foot. Turn it (some push up and down) just a tad in either direction and recheck with a scrap of fabric to see the results.
Hope this helps!

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
SOURCE: Bobbin continues to pose problem - knotting thread underside of fabric,
In 99% of all problems with "bird's nesting" or "knotting" it is an issue of the thread coming out of the take up lever (at threading guide #3) (from the spool; through the first thread guide at #1 down to #2 and up to # 3) when the thread comes out of the take up lever, the machine can not regulate the thread and it floods the machien with thread and wraps itself around the bobbin case. OR! Your tension is too loose. Raise it. Your machine should preform perfect at tension #4 unless you are using speciality threads or fabrics.
ALWAYS be in the habit of threading your machine with presser foot up so that while threading between paths 1 and 2 you are certain to have the thread pass throught the tension disks.
This will happen on a $50.00 machine or a $5,000 machine. The thread needs to be regulated.
USE GOOD THREAD!
Thanks,
Bonnie
SOURCE: thread clogs up bobbin and knots up thread on back side of fabric
hi there,
well, common problem when you didn't acquired right set up of tension and clean feed dog,bobbins,shuttle race.on figure right bobbins winding.
set up counter clokwise thread rotation, set dial tension on #3 to #4, dial stich to # 8 to #12
only on cotton fabrics,others fabrics such as silk..etc,gradually adjust tension fine the smoothest adjustment,
on fig,thread looping top side threading
follow threading so you can have fine sewing.also clean under bobbins from chips fabric and dust.have a nice day,don't forget to rate my fix,ythanks a lot
SOURCE: bobbin problem
When you thread your bobbin and put it in the case the thread should be on the left side of that little arm on the bobbin case. It allows the thread to slide off that arm.
Another issue could be your lower tension. You may need to loosen or tighten it.
I had the same issue and the above two things eliminated the problem.
