Upper tension too tight. Have changed tension to almost zero. Have cleaned and oiled machine. Double checked thread is threaded correctly. Changed needle. Sometimes when sewing fabric will gather.
Re: Upper tension too tight. Have changed tension to...
You need to check to see if your bobbin tensioner has broke. Look at your schematic to determine if everything is still where it's supposed to be. Good Luck.

Check the thread: Make sure you are using a good quality thread that is appropriate for the type of fabric you are sewing. Poor quality thread or thread that is not suitable for the fabric can cause shredding and breaking.
Check the needle: Make sure you are using the correct size and type of needle for the fabric you are sewing. A bent or damaged needle can also cause thread shredding and breaking.
Check the tension: Check the upper thread tension to make sure it is set correctly for the type of fabric you are sewing. If the tension is too tight, it can cause the thread to shred or break.
Check the threading: Make sure the upper thread is threaded correctly and that there are no tangles or knots in the thread path.
Check the presser foot: Make sure the presser foot is properly installed and that the fabric is being held firmly in place while you sew.
Check the machine settings: Double-check that the machine is set to the correct stitch length, stitch width, and other settings for the type of fabric you are sewing.
If you have tried these steps and are still experiencing issues, you may want to consult with the technician who serviced your machine
ALWAYS RAISE the presser foot during the threading process and rethread the machine from the beginning. (Check that the upper and bobbin threads are threaded correctly in your machine.)
Set the tension dial to the midway point. This is a factory standard setting but each machine may vary.
Test your machine. The ideal tension is when the upper and bobbin threads meet in the middle of the fabric. If the upper thread is showing on the bobbin side of the fabric, the upper tension is too loose. However, if the bobbin thread is showing on the top of the fabric, the upper tension is too tight.
Tension is not static--whenever you change projects, ie fabric, thread, needle, you may need to test the tension on some scrap project fabric first. Get the tension adjusted before stitching the project.
Make sure you clean and lubricate your machine regularly to keep it operating--consult your owner's manual and use only good quality sewing machine oil (NO 3-in-1, cooking oil, WD-40, or old brown stinky sewing machine oil).
If you are still having issues, take it for service.
Depends on the make/model of your machine. Different machines require different care. It is important to clean and oil frequently as directed in the owner's manual. Be sure to use the correct oil--no 3-in-1, WD-40, cooking oil, or old and stinky sewing machine oil. (If it is brown, throw it out!!!) Also, one or two drops each spot is sufficient--do not over-oil!
Problems with tension? Install a brand new needle.
Remove the upper thread completely from the machine. Raise the presser foot and rethread from the beginning. Confirm that the thread path is correct.
Set the upper tension to the midway point between high & low numbers (this is a good beginning point, but may need some tweaking, especially when dealing with different threads and fabrics).
Confirm the bobbin is loaded in the bobbin case correctly and threaded properly.
Test your machine. If the upper thread is showing under the fabric, the upper tension is too loose. If the bobbin thread is pulling to the top of the fabric, the upper tension is too tight.
Tension is correct when the upper and bobbin threads meet in the middle of the fabric.
You might try cleaning the tension disks by dampening a length of pearl cotton with rubbing alcohol, open the tension disk all the way, raise the presser foot, and then pull the pearl cotton down between the disks a couple of times.
Clean away the lint and thread pieces from the feed dogs and bobbin area. Oil your machine according to the instruction manual--use only fresh good quality sewing machine oil--only 1 or 2 drops of oil each place.
Install a brand new needle. Make sure you are using a needle and thread that are compatible with the fabric you are sewing--that the thread is not too big for the needle's eye, etc. All About Needles
Make sure you RAISE the presser foot BEFORE threading the upper thread. Rethread the thread from the beginning checking that thread is not wrapping around the spool pin or catching somewhere in the threading sequence.
Verify that you are threading the machine correctly. Misthreading will cause havoc and frustration!
Do not use old or bargain bin thread--Coats & Clark does create problems for some machines.
You might try pulling the bobbin thread to the top before beginning to sew. This helps prevent some of the thread nests you are experiencing. How and Why to Bring up the Bobbin Thread
The factory tension setting is usually the halfway point between the high and low number. This is where you should start testing your tension. Once you sew a sample, if the top thread is looping/knotting (bird nesting) under the fabric, the upper tension is most likely too loose. If the bobbin thread is pulling to the top of the fabric, the upper tension is too tight. Get used to adjusting the upper tension every time you change fabric, needle, thread. The upper tension is not meant to be static, so don't be afraid to adjust to achieve the proper tension.
Ideal tension is when both the upper thread and bobbin thread meet in the middle of the fabric.
1. While threading put the foot up.
2. Give gentle tugs along the way. It should be without feeling any hangups.
3. Wherever the hangup is you must correct. Usually at the tension disc.
4 Sometimes the tension disc is tightening more than the indicator says. It should be about four. You can lower this tension setting until the stitch looks good.
5. You may have to take the tension assembly off and clean it thoroughly and sand any rusted spots.
try cleaning cleaning the tension disks, remember you tension setting,, take some unwaxed dental floss and go between the disc's to clean in them, and then reset the tension disc's by to normal
Hello Rosemary
Looped thread on the underside are created by the upper thread. Loops on the top of the fabric are created by the bobbin thread. Whichever one is looping, has very little tension. This may be corrected by:
1. Re-threading the upper thread according to manufacturer's specifications.
2. Re-wind bobbin and re-set it into bobbin case and bobbin case area according to manufacturer's specifications.
3. Ensure that the needle is correctly installed and is the correct needle for the sewing machine.
4. Ensure that he bobbin being used is the correct one for the machine.
5. Double check that the tension on the upper thread is at the correct setting.
6. Double check that the tension unit is clean and free of dust, lint or lodged thread/s.
7. Double check that the bobbin tension is correctly set ... if you are comfortable doing so, otherwise leave it for a qualified technician
8. Make sure that he presser foot is down when stitching.
Please let me know how you go.
Happy stitching.
