Guide the the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.)If it doesn't work like this, then there is probably thread stuck inside the tension assembly. Set the tension to zero and blow hard between the discs to dislodge the thread. If it passes this test, continue up through the take up lever,then down through the thread guides to the needle.

Check to be sure you have the correct bobbin and that it is inserted the correct way.
OR remove the needle plate to remove the bobbin case. Look for any burrs or rough spots. Use a fine emery stick and steel wool to remove and buff them Reassemble and try again.

The stitching is not right. It looks fine on the top of the fabric, but bunches up on the bottom


Looping or bunching on on the bottom is a result of problems with the TOP TENSION.
Rethread the upper thread and adjust tension. Try again.

I have the Kenmore sewing machine #16231. When I was sewing the bobbin holder popped out and a bunch of thread bunched together and wrapped around the bobbin and caused bunching of thread on my fabric...


Bunching of thread is 99% a top tension problem. Make sure you thread the top thread correctly. Thread the machine with the presser lever up. Test the tension by lowering the presser lever before threading the eye of the needle, by pulling the thread with your left hand and adjusting the tension with your right hand while slowly pulling downwards. There should be no resistance when the tension dial is on zero, and you should be able to feel more resistance when you increase the tension. Ideal tension is between 3 and 5. When your top tension is correct, your machine should operate correctly. If you feel no resistance with the presser foot down and the tension dial on 5, check the tension disks for fluff or broken thread. When you lift the presser foot, the tension disks should open and you would be able to remove any cotton or fluff. Good Luck

My bobbin is bunching and the thread is catching on something internally. It is not sewing anything together and is not tension related. My bobbin case has an imperfection where a needle stabbed it. Do you...


I really think that it is from being threaded wrong, make sure the thread is seated into the top tension disc and that you also have the bottom threaded right through the bobib case. If it is a burr your talking about on the bobin case holder than you can try to lightly sand it off

Sewing a bunch of thread from the bottom, this stops the machine from actually sewing


Yes, it does. There are a couple of reasons the bobbin thread could be bunching up on the underside of the fabric. It could simply be that the machine needs cleaning. Take the bobbin assembly out, brush all the old lint out as best you can, reoil the machine once it's all clean, and make sure there aren't any little bits of thread caught in the bobbin assembly. Rethread the machine (carefully) and change the needle. This solves the problem usually--especially if the machine was sewing along fine and the problem develops suddenly. '
The other thing to check is your tension. It could be that the top tension is too loose. But different color thread in the top and in the bobbin, stitch a few inches (be sure to held the top and bobbin thread ends behind your needle as you start to stitch) and check. WIth the pressure foot down, adjust the tension, and stitch again. Keep stitching, checking, and adjusting until you see little if any bobbin thread on the top or top thread on the bobbin.
Another thing to reminder: use the appropriate thread and needle for the fabric you're sewing.
Let me know if this works, ok?

Bobbin tension problem with kenmore model 385.16231300


If You have a drop in bobbin you will have to remove the hook and adjust the tension, however try adjusting the top tension before you remove the hook.

Wont sew thread bunches up


Hi!

I think you are threading the top of the machine incorrectly. Make sure that what I'm saying is correct, use two color threads to sew with- and you will see that it is in fact the top thread that is bunching.

This might be a tension problem. Could be the bobbin is not threaded in the case right. First, check the threading of the bobbin and then check the stitch.

Next, adjust the tension on the bobbin case. There is usually a small screw on the case that can be tightened or loosened. I think you may need to adjust it a bit or adjust the top tension knob, just a small bit at a time. It the top does not change the stitch, then go to the bobbin case and adjust the screw to tighten the stitch a little bit more.

Please do rate this solution as FixYa and revert for further assistance.

Thanks

Im pretty sure i have my singer 5525 threaded right but i think the bobbin is wrong but when i try to sew the top looks fine but the bottom is a thread mess an the thread keeps breaking


angle the bottom might be a mess but it is the top thread that
you see balled up .Pull the top thread and make sure there is tension on it ,if not check the thread is between the discs and there is nothing else between them .if this is ok there is something stopping the top thread from being pulled back up
through the needle plate to form a good stitch,if you can turn by hand and watch where it is catching you might be able to solve it.

I have model 8280 and the bobbin thread keeps bunching up on the bottom. I have tried to rethread it but it keeps happening.


i think your putting in your bobin backwards,
to check put your bobin in and hold bobin , and bobin case by thread if it unrolls its backwards,
hope this helps!!
