Re: stitching 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 cotton through 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

Bobbin tension

Masses of thread on the underside is actually a top tension problem. If you can see into the top tension area, make certain there are no jammed threads, lint, yecch in there. Lift and lower the presser foot lever and see if the tension opens and closes. If it does not, it may be stuck open and not putting any tension on the top thread. Make sure your top tension is set in the middle of its range.

The machine is not stitching correctly,especially on zig zag # 3 stitch selection. I put two different thread colors and the zig zag on the front and back of fabric are both the bobbin thread. Now the...

If the bobbin thread is coming up to the top, then the thread is not under tension correctly. I think that this is a top loading bobbin so the bobbin will go into the bobbin holder, then you pull the thread back and press it into a tension device - should hear it click into tension. Now pull the thread back towards you and it should not come out of the tension. The bobbin should turn anticlockwise as the thread is pulled from it.

These bobbin holders usually will have a small adjustment dial on them and it should have the standard setting marked in red. It is very unusual that you would need to change this but check that it hasn't been messed with perhaps. If you have the machine manual check where they say the dial should be set. More likely that the thread is just not into tension fully or at all.

The manual may give you other troubleshooting tips too.

A good resouce is for general machine tips, cleaning and threading issues.

Hope this helps.

There has to be a problem in your threading or your needle. You may have the needle inserted backwards, flat side has to face rear or the needle is bent. Totally unthread your machine and make sure that there are no tangles and that it feeding the right way. Watch how they show your for threading and winding the bobbin, plus threading the bobbin. Good luck, but I truly think it is in your threading.

Mine is doing the same thing. It's pulling the thread up from the bobbin and making a huge knot. Any suggestions. I've done all the above checks. Brand new needle, tension is on embroidery, threaded properly and no lint in bobbin compartment.

Tension issues with the bobbn area

No, I have not had a consistent problem with this.

What looks like a bobbin issue could be a threading issue.

If a sewing machine is threaded with the presser foot down, the tension control does not capture the thread as it should. The top thread then cannot form a proper stitch with the bobbin thread.

If I forget to have the presser foot up when I thread, then I get loose stitching on top and loopy stitches on the bottom.

Pfaff varimatic 6091 sew a rag quilt with jean and flannel,I can't get my tension right it seems to be funny on the bottom stitch,where shoulf the top tension be set at 4 1/2 ,when do I adjust the bobbin...

Hi! The bobbin tension rarely needs to be adjusted. First, make sure you're using the appropriate size needle and thread for your fabric (I'd probably use either a 'denim' needle or a universal size 14) and also that the upper thread and bobbin are threaded absolutely correctly. These can throw off the tension! Also, take the time to clean out the bobbin area. That can throw your stitch off also.

If the stitch on the bottom is loose, so that you see the top threads, then the top tension is too loose. If the top stitch is too loose and you see the bobbin threads on top, then the top tension is too tight.

It helps to thread the machine with different color thread on top and in the bobbin, and then stitch an inch or so on the same type of fabric as you're using in your quilt. Check the stitch. If you need to adjust the top tension, make sure the pressure foot is down! Adjust a little, stitch a few inches, and check again. Repeat until you don't see any (or very little) bobbin thread on the top or top thread on the bottom.

If you go through all these steps, and the bobbin thread is still loose (and you've tightened up the top tension), then there is a tiny little screw on the side of the bobbin case that you can use to adjust the bobbin tension. Turn the screw just a little bit (less than a quarter turn), stitch, check, etc. Once the bobbin tension is set, you shouldn't ever have to change it.

Let me know if this helps, ok?

Happy sewing!

Bernina Aurora 440 knotting below my fabric and into bobbin area.

Are you sure you have the bobbin the right way round in the holder....when you look at the bobbin and tug the thread, the bobbin should move clockwise.
Pull out the foot pedal and use bsr2 with the start/stop button.
Bring bobbin thread to top of work before starting to sew. This may help knotting problem
