Question about Sewing Machines

4 Answers

I just bought a singer stylist 9100 and its driven me to tears. The bobbin thread keeps couching through the top of my quilt, pulling the top stitches into a tight blanket stitch looking mess. I have cleaned it out and rethreaded different threads spools bobbins and needle. This is my sixth needle in two days. Changing the needle has helped in the past but it's getting ridiculous. It seems like the top thread is too tight but the tension dial is on three. I am trying to freemotion quilt with the darning foot feed dogs down and stitch length is 0. Changing the foot back to regular foot seemed to stop it. Machine is set for medium speed as well I need to finish my quilts off please help!

Suggest you check your bobbin tension, pull the bobbin thread and if you feel it too loose, most likely bobbin thread not threaded correctly into the bobbin case tension plate. Do refer to your manual if you have one.

I would suggest taking the machine to a sewing machine shop and have the top thread tension dial check to see if there is something wrong with it, also the bobbin thread tension may need a adjustment.. and that's something you don't want to do unless it's nessary, if you decide to try to adjust the bobbin thread tension, I suggest looking at a youtube video, or try sewusa they have some troubleshooting information...

I am getting the exact same problem! Sometimes it works fine and other times (mostly) the top thread seems to be too tight.
I've troubleshooted, re-threaded a million times, bought good quality threads....nothing seems to be working. I am out of ideas and it's driven me to tears so many times too!
Anyone have a solution to this??

I had a similar problem, but all the stitches were bunching badly underneath the material. I had to adjust (loosen) the bobbin case tension by over half a turn to get the machine to sew acceptably. There are also a couple of errors in the manual, and a glaring lack of information - eg: what bobbins does the machine take? A google search gives conflicting answers - this basic info should come with the machine.
One tip I finally worked out - if you are sewing a name or phrase, once you have saved the sequence of letters, go into edit mode and set the lockstitch option FOR THE LAST STITCH ONLY! Otherwise the machine starts to repeat.
Also, there arent't "Memory Modules" - it just has 4 memories, each of up to 20 stitches.
If you have the foot controller plugged in, and you press the start/stop button, if gives the 3-beep error code.

    I agree it seems like the bobbin tension is way too loose, so tighten it one-eighth of a turn at a time. To adjust the bobbin tension, remove the needle plate (and neither of the supplied screwdrivers fit), then loosen the two screws holding down the finger in the rear left hand corner, so that you can lift the bobbin case out. The tension screw is the left hand screw, coated with a anti-loosening paint. (Neither of the screwdrivers fit the bobbin case either).

My new Singer Stylist 7258 keeps getting a message code C4 and I can't find anything wrong with it. Please advise.

I looked in my manual, it says that C4 means that the thread is tangled or there bobbin was interrupted forcibly. Turn off and totally rethread your machine with presser foot up, insert a new needle and try again. Do this test, with the presser foot up, pull top thread, it should move easily, now lower presser foot, pull thread, it should barely move. This should seat the thread in the tension discs properly. I have this same machine, and love it.

Threading bobbin on singer stylist 522

To wind a bobbin put the cotton reel on the top pin, take the thread to the left and round the little wheel and back to the bobbin that should be on the winder, wind the thread round a few times to take a grip, release the stop motion in the balance wheel, turn the winder button so the winder moves to the balance wheel and press on the foot control slowly.
When you put the bobbin in the bobbin case make sure it turns anti clockwise.

I have a Singer Inspiration 4220 Sewing Machine. I was working on a quilting project last night, and everything was going fine, until I noticed that the thread on the underside of the fabric was very loose...

It's possible that there is foreign debris in the top tension assembly ,thread the machine and lower the presser foot and ensure that there is tension on the top thread

Bobbin thread breaks

Make sure your bobbin thread is turning clockwise as it sits in the bobbin case. There is a screw on the outside of the bobbin case you can turn with your thumb slightly to adjust tension. If you dangle the case from the thread and give it a light ****, it should move down slightly when doing so-an indicator of good bobbin tension.
