Threading CG-590 Cannot thread Singer CG-590 properly. Thread on underside of fabric keeps looping and knotting up. Have re-threaded the machine 7 times with no different outcome. Manual says thread not entering the upper tension disks correctly, but when I do it, it looks exactly like the illustration says it should. Help!

Re: Threading CG-590

Regarding thread bunching up underneath the fabric on the Singer CG -590: my husband just discovered that I had my thread incorrectly wound through the first thread guide. It was allowing too much slack in the thread. I missed the piece that is described in the manual as follows: "Lead thread passing it first under the thread guide. Next through the upper slot, leading the thread to the right and around."

I am having trouble getting the bobbin to function properly during sewing.

It could be the top thread is the problem. Might try removing all the thread. Consult the owner's manual for threading instructions. RAISE the presser foot BEFORE threading the upper thread so the thread will seat properly in the tension disk. Re-thread from the beginning carefully following the instructions--do not miss any spots or thread guides.

If top thread is still creating a mess of loops under the fabric, try tightening the upper tension. The tension is ideal when both upper and bobbin threads meet in the middle of the fabric.

Cant get my bobbin in right position it keeps knotting up on inside of fabric

Top thread problem, Not enough tension on top=loops on the bottom of the fabric; too little tension on the bottom = loops on top of the fabric. Yes, I know it seems backwards. See:
Dollars to donut holes, you either threaded the top of the machine with the presser foot down (it has to be UP to let the thread into the top tension), or you're trying to sew with the presser foot still up (which is an issue common to people trying to sew bulky seams).

Take the thread off the top of the machine, take out the bobbin case and give the machine a cleaning, rethread the machine, fetch up the bobbin thread and hold the bobbin and top thread ends together under and behind the presser foot for the first 2-3 stitches of each seam.

I think the bobbin tension is off - I have large thread loops on the underside of the fabric when I sew

It sounds crazy but if you have loops on the underside of your fabric it means your upper thread is not properly threaded (and vice versa for loops on the top of your fabric). So re-thread your top thread, change to a new needle if you've been sewing with it for a months and you should be good to go. Let me know if you need any more help.

Thread mess at the underside of the fabric

Hi, maybe your bobbin is turning the wrong way and you need to flip it over. Or you don't have any top tension. Be sure the thread is in between the tension disks with the foot up. Its also possible that there is a burr on the hook part that goes around and grabs the top thread. The thread will catch on the burr and cause this issue. Usually after breaking a needle. Then the burr would need to be polished off.

Try oiling the hook if you haven't recently.
Check you needle plate and hook for damage, they may need to be buffed or sanded smooth.
Check your upper tension discs for lint and double check your upper thread path (proper threading).
There are other things like hook timing, needle clearance or broken check spring that may be wrong but you need a technician for those things.
best of luck!

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.

Singer 5525 sewing machine knots up thread on underside of fabric after three stitches

most commonly this is from incorrect threading top thread. Check manual for threading path or follow threading path usually marked by arrows on machine
