My sewing machine problem (Brother CE 8080 prod. code 885-V61) is tangled thread on wrong side of fabric, I followed the troubleshooting remedy but it still exist

SOURCE: Brother Sewing Machine model:CS8150 bobbin thread problems

The top of the machine is not threaded correctly. First raise the presserfot then rethread the machine. Bottom looping is usually caused by a lack of top tension. There could allso be a bur on the hook.

I had this same problem yesterday. I took apart the needle tension casing and now it doesn't get tangled or stop. The only thing is the bobbin is not sewing...it looks fine on the top, but the bottom is just loose loops.

This is easily solved. Before you start sewing make sure your upper and lower threads are long enough for you to hold before lowering the presser foot. If these threads are too short they both get carried down into the bobbin along with the fabric and cause a big tangled mess. Always hold your threads at the back of your work with your left hand then lower your pressure foot and don't release the threads untill you have taken several stitches. Keep holding these threads during backstitching at the beggining of a seam too. Works like magic.

Does it sew okay on a single or double layer as this sounds like the threading up is not correct to me. The grinding may be that the bobbin case isn't in correctly.

However, best way to diagnose is to start fresh, take off the thread, remove the bobbin case, clean out the rotary hook (under the needle plate) clean the feed dogs and remove the needle. Clean the tension discs too (turn to zero and floss between the metal discs with selvage edge of a clean piece of cotton scrap fabric, until its clean, no gunk coming out). Turn tension dial back to 4 or 5, your normal setting.

Now wind a fresh bobbin making sure it winds nice and smoothly, keep tension onto the thread spool to achieve this and watch as the thread goes onto the bobbin, give it a nudge so it fills the bobbin smoothly across the whole core, top, middle and bottom.

Now put bobbin into bobbin case and ensure it goes into the tension spring correctly. I can't see an image of your machine to know if it is top loading or front loading bobbin, sorry. But refer to your manual to ensure you get the thread fully into the tension device. With a front loading bobbin, there is a removable bobbin case. Ensure that this is holding the thread with enough tension, if you suspend the bobbin and bobbin case and just hold the thread tail there should be enough tension on the thread that the case just hangs, but if you give it a litle jolt, it should release some thread. Adjust the tension spring with a little screw on it in 1/4 turn increments until you get it to this point.

If you can't get the tension right on the bobbin case at all, then take it to the Brother shop and buy a replacment one, sometimes the springs do fail on them.

Now put in a new needle and make sure you have used the right size needle for your fabric, ie medium weight woven you need a size 80 universal, but if it is a knit fabric like jersey you need a ballpoint 70 or "stretch 70" if its got a lot of lycra in it.

Now thread up the top thread and pay careful attention to getting the thread into all the thread eyes, particularly the take up lever and make sure it goes into the top tension discs fully (always thread with the pressure foot raised so the tension device is open). Lower the pressure foot and pull the thread just before the needle, it should feel very firm if the top tension is working right. If there is no resistance there, you've got a dodgy tension dial, take it for service/replacment.

Continue threading to the needle, bring bottom thread up to the top by turning the flywheel through one cycle towards you. Now hold both threads together at the back and test stitch a seam.

If you are still getting the noise from it and thread jamming up underside then the fault may be more timing related in which case you'll need to take it to a sewing machine technician too.

This means your tension is incorrect. That circle with numbers about the needle is typically set at three. If not, start there and experiment number by number until your threads are equally taut on both sides.
