First the top tension started being loose, so I changed the tension different ways and tried to fix it...now the thread is getting all tangled up under the fabric and is locking up. Also giving me the E6 code...so I read the manual and took the bobbin and holder out and cleaned it. I put it back in the way the picture shows and it still tangles underneath and screams and locks up with the E6.. Thank you for your time....Brenda

is it the top thread that is too loose and making the messy stitch or the bobbin thread. if it is the top thread coming down and making large loops that tangle increase your top tension slowly try a few stitches, repeat till you get back to normal.
If it is the bobbin thread that is tangling, first make sure you are using the same thread top and bottom, some will just not work together, then rethread the bobbin, if it is still too loose there is a little screw on the side of the bobbin casing, the larger of the two, turn it no more than a 1/10 turn to the right if too loose and to the left if too tight. I would make the starting point with a piece of tape or nail polish so you can get back to where you were if this is not the problem. My book says you very rarely ever have to touch the bobbin tension. good luck

try a new needle

make sure the bobbin is inserted correctly,, counter clock wise

also check the upper thread tension, also check to make sure there aren't any loose thread or lint in the tension disc area

make sure the top thread has not come off the thread take up lever

check in the bobbin area for lint or loose threads

Hi:

Ok... so try to remember that loopy stuff on top means the bobbin tension is too loose (or the top tension is too tight...)

Loopy stuff on bottom, means the top tension is too loose. (or it's not threaded right)

Now. Get some scrap of the same material. Loosen that bobbin back to where it was. RETHREAD the top, with the foot in the UP position.

Place your scrap under the foot, and sew. still have problem? clip your threads and try again only this time hold the top and bottom threads off to the side as you begin to sew. How did that do?

Adjust the top tension to the point where you start seeing the bobbin thread come up in loops to the top... then back off until the disappear.

Now... be sure you have the correct thread and needle for your fabric. A lot of problem are caused by not having the proper needle and thread.

try changing the needle---flat side goes to the back side of the machine
also check the top tension
depending on the fabric your sewing on--the needle & thread have to work
with the fabric--example light fabric needs a different needle & thread than
a heavy fabric
check to see if the thread is coming off the thread take up lever when you
sew.

Ironically, often times when the bobbin thread is knotting up, it's the top thread that needs the adjustment. Loos top thread thesion will tangle up in the bobbin cassing...Think about it for a minuted. Try a quarter turn to the right on your top tension and then go fro there. There could be a problem with the bobbon casing tension adjust screw and plate. but I doubt it...Nine times out of ten when the bobbon thread is tangles the top thread is too loose.

Your tension is way too loose on top or too tight on the bobbin. Try adjusting the top tension one number at a time until you get it right. (Only adjust the bobbin tension as a last resort). Also you could have different thickness of thread in the bobbin than on the top or are sewing a very heavy fabric. Try adjusting the tension with same thread in both bobbin and top and use a normal weight fabric until you find the right tension to get you back to a normal stitch before going to a heavier fabric or thread.

If you are getting a thread mess under the fabric, it is a top thread problem.

Remove the top thread completely from the machine.
ALWAYS RAISE the presser foot and rethread from the beginning. Verify the thread path is correct.
Retest your machine and tweak the tension, if needed.

...

Stop sewing! You need to adjust your tension. Your book will explain exactly how to do this. If you can't find your book, try setting the tensions to the same number. If your tension adjustments have a mark at a certain number, use that setting for most materials. If not, try setting it to about 3.

To test your settings, thread your bobbin with a different color, then do a test stitch. Check the top and bottom stitches for a spot of the other color thread showing through. If the bobbin thread shows in the top, raise the bobbin tension setting a bit and try it again.

Hope this FixesYa!

Hi, Is it your bobbin thread or the top thread wrapping around the bobbin. I just got a used PE150. The top thread keeps wrapping around the bobbin. It is not picking up the bobbin thread. Did you find a solution for your problem?

When your thread is bunching at the bottom, your top tension is not tight enough, or you did not thread the machine correctly. Make sure the thread goes through the tension blades. Check your manual how to do it properly. you can check if there is any tension by pulling on the thread before threading through the eye of the the needle, and with the presser foot down. By pulling with the left hand and adjusting the tension with the right hand you should be able to feel a difference. Normal setting is between 3 and 5
