Ok, please don't take this the wrong way, but I only mention it because this happened to me: are you sure you're threading the machine correctly? I've had mine for two years and finally realized the other day that I was passing the thread behind the tension disk when it should have been in FRONT of the tension disk. I didn't have tension problems all the time when it was misthreaded, which is why I guess I never realized I was doing it incorrectly. One other possibility: if the thread spool is vertical, trying standing it up (you may need to rig something with a coffee cup and some safety pins taped to the machine, but most machines provide both vertical and horizontal spool capabilities); if it's horizontal, try moving it to a vertical position. Some threads don't care which direction they are; others are VERY finicky about this.

I am sewing voile curtains, but the stitching keeps looping on the underside

Check your sample. Is it the top thread that is looping under the fabric? That is called bird nesting or thread nesting. It happens frequently if the top thread is not seated completely in the tension disk. It could also be a top tension problem.

Be sure to use a brand new needle compatible with the thread and fabric.
Remove the top thread from the machine.
ALWAYS RAISE the presser foot and rethread from the beginning.
Set the top tension to the midway point and test on a scrap of the same fabric. Adjust the top tension until the top and bobbin threads meet in the middle of the fabric. (Tightening the top tension will pull the bobbin thread up. Loosening the top tension will allow the bobbin thread to pull the top thread down.)

The stitches on the underside are looping I’ve retreaded both the needle and bobbin and neither makes a difference

You are getting a thread mess under the fabric? Frequently, this occurs because the top thread is not fully seated in the tension disk.

Install a brand new needle.
Remove the top thread from the machine.
ALWAYS RAISE the presser foot and rethread the machine from the beginning.
If necessary, adjust the top tension so the top and bobbin threads meet in the middle of the fabric.

My thread keeps looping on bottom Have changed tension, needle rethreaded and changed bobbin nothing helps what am I doing wrong?

not sure if this will help you...Check Your Tension Settings. Looping underneath the fabric usually occurs when there is not enough tension in the needle thread to pull the bobbin thread. Sometimesthread buching can be caused by something as simple as the tension dial being inadvertently turned.

What is the proper tension number for a normal straight seam

Usually, the midway point of the upper tension dial is the standard factory setting. However, machines change with age and use. The correct tension is when the top and bobbin threads meet in the middle of the fabric. (However, that means you should test/reset the tension whenever you change projects because different fabrics may require a different tension setting.) Don't be afraid to adjust the top tension. You know where it started, so if you turn the wrong way, you can always undo it.

Adjusting the bobbin tension is usually a last attempt as it is very sensitive and is difficult to undo. Bobbin tension very seldom requires adjustment.

HINT: When threading the top thread, ALWAYS RAISE the presser foot and rethread from the beginning. Install a brand new needle when beginning a new project, after 8 hours of sewing, or if the needle strikes something on the machine. (A new needle is very inexpensive when compared to frustration, damaged fabric, or machine repair expenses.)

Back side of stitches are loose

increase the thread tension of the needle thread
this is an indication that the tension is not enough to pull the bobbin thread up tight

HD 3000 loops underneath work

It's most likely not the machine. It's the other things, ie needle, thread, etc. combination. For sewing knit, be sure to use a ball point needle. The needle eye size is important to so the thread is neither too small nor too large for the thread weight.

FWIW, it sounds like bird nesting. --the thread is not seated completely in the tension disk. Remove the top thread from the machine and ALWAYS RAISE the presser foot when rethreading!

Also, check that the tension is appropriate for the project. The two threads should meet in the middle of the fabric. If there is top thread showing on the underside of the fabric, the top tension is too loose. Tighten it until it until the top thread pulls the bobbin thread up into the fabric.

My Janome Sewist 500 is making me crazy. The tension is loose on top, causing loops on the back, and the bobbin thread is just a straight line. I have changed the needle, changed the thread, rethreaded...

that sounds like the top tension dial is not working, causing looping on the underside so start by cleaning out the top tension device. To do this, unthread, turn tension to zero, then "Floss" between the discs with the selvage edge of a clean piece of waste fabric. If some black gunk comes out onto the fabric, then refloss on a fresh edge until its clean.

Then reset tension to 4 or 5 and thread up again until just before the needle. Now lower the pressure foot to engage the tension device and pull the top thread downwards - it should feel firm. If this is not happening, then I'd go the serviceman next. These things have a spring in and it may have broken.

I think the bobbin tension is probably okay so just reset that back to what it was, the straight line on the bottom is because the top thread is not being drawn back up by the take up lever on the upwards stroke due to insufficient tension on the top thread.

Hopefully cleaning the tensioner works though. Good luck.

The top stitch is perfect but underneath the material there are many loops. I am assuming this is from the bobbin. How do I correct this?

no, more likely your top tension is too loose causing the loops on the underside of your fabric, loops on top would be bobbin too loose. raise presser foot and rethread top thdead pulling thread into tension fully. set top tension dial to 5 and test sew. if still looping underneath try tightening top tension by turning dial up to 6. but usually top tension should only need minor adjustment tweeks. you can test top tension by lowering pressure foot to engage tension and holding thread just above needle thread guide, pulling thread downwards . there should be resistence on it to your pull. if you cant feel any then tension device may be faulty, and require service.
