Re: Thread getting stuck in the bottom.

Mine is also doing this, but it has an auto tension and doesn't have those numbers on it. It is the 7422 Advance. I just bought this machine and have yet to be able to do anything with it. Very disappointed. Taking it back ASAP and never buying Singer again. Machine locks up for nothing, have to turn off and back on and it works, then the thread bunches up at bobbin and I have checked everything. And it was suppose to be able to accomodate a little bulk, (doing a quilted christmas stocking), however the fabric will not feed and it just starts to bunch up. Good luck

I am having a problem with the thread knotting up on the bottom of my material. The needle starts to lock up and when I start checking the thread is all knotted up. I then take the bobbin out and it...

What you have going on is probably a bobbin problem. The knots are referred to as birds' nests and happen usually happen when your bobbin thread gets caught on something in the bobbin area. To be certain it's a bobbin problem, change your needle. Even if the needle looks fine, it could be just slightly bent and still look fine to the naked eye. If that doesn't solve the problem, take the fabric out of the sewing machine and turn the machine wheel by hand. Watch what happens thru the plastic window in the bobbin area, or if you don't have a plastic window leave the bobbin covering off. Is the thread catching somewhere and causing a bunch of thread to gather in the bobbin area? Be very careful when investigating in the bobbin casing/area-it's easy to chip things in there! Often times, a piece of something falls in there and can be pulled out with tweezers. Just as often, the bobbin casing is slightly tilted and needs to be straightened or has a chip in it and needs to be replaced. You can normally get a replacement on eBay, searching with your machine model number. Also, check out SewVacUSA. If you need help replacing the bobbin casing (it's easy, you just need to be careful), or if these solutions don't work, leave me a comment. I check back daily, so I'll get back to you within 24 hours normally. Leave me as much detail as possible and I'll do everything I can to help you!

Hi, using a jonome finesse model 356, changed the thread on the bobbin and now its knotting up and not loose from the bottom, did i thread it incorrectly? tension is wrong now?? thanks!

Check that the thread is tight around the bobbin. Make sure that the bobbin is in the right way around - the bobbin thread should double back on itself coming out of the bobbin holder. The bobbin tension adjustment is the small screw in the plate on the bobbin case that the thread passes under as it comes off the bobbin and goes out.

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.

Bobbin Thread is "birdnesting"

Get out the manual and refer to the maintenance section for cleaning the machine.

Especially the bobbin area. You want to make sure the area around the bobbin case is free of lint and thread.

Use a new bobbin and re-thread the machine, with the presser foot UP.

Install a new needle, again according to the directions in the manual. Installed incorrectly can lead to mis-stitching.

If the problem persits, the timing may need adjusting.

This should be done by the sewing machine tech for Kenmore. has a guide for this in the repair section, but you could end up with more problems.

Thread stuck around the bobbin housing on my

try cleaning all that you can out of the bobbin case then try very carefully to bump it backward (opposite) with the hand wheel . Be careful not to knot out of timing. sounds like you have thread in between bobbin case and hook

Husqvarna Vicking - The bobbin thread is knotting

Check that it is threaded correctly (both top and bottom) making sure that the upper thread is in the takeup lever. Watch the needle as you slowly turn the handwheel counter clockwise (toward you) and the needle point touches the fabric (make sure presser foot is down). Is the thread still relatively taunt? If it is loose, the upper thread tension unit does not have enough tension. Check the areas where the thread goes and make sure you remove any loose threads or fluff which could be inhibiting the tension discs from closing over the thread. If the tension unit still is not tightening enough, the tension unit may need to be replaced or the circuit board replaced. If everything is ok in the upper thread area, now look at the bobbin area. With no fabric, watch as the needle enters the bobbin area. Does it go down and the upper thread catch the bobbin thread and pulls it to the surface? Check for anything preventing the bobbin thread from being pulled up to the surface through the needle plate. If you have still not been able to resolve the problem suggest you take it to an authorized husqvarna viking dealer for service. You can locate a dealer near you by visiting the husqvarna viking website and clicking on the Dealer link on the left-hand side of the page -

Good luck.

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

Upper thread knots up with bobbin thread when sewing a stich

Thread test
Test your thread quality to start, thread your machine and LIFT the presser foot (this opens the tension disks). Pull your top thread straight back. If you feel no tension no mater how much thread you pull, your thread is good. If that your machine passes that test, then let me know, we can go to step 2. If not, try different spool of thread, same test until you get a smooth pull (tip: always check your thread this way when you thread your machine)
Step 2:
Pull on your threaded bobbin thread while it’s in the machine. Does it pull smooth and even? If so, go to step 3. If not, try a new bobbin (bobbins get bent or distorted if wound too tight).
Clean thoroughly in the hook and bobbin case area and oil 1-2 drop is all.
Thread knotting on the bobbin can be a lot of things but here's some guidance:
If the thread is loose on the bottom of the fabric, it's actually the top thread is too loose. Think of 2 little elves playing tug of war in your machine, one on toip and one underneath. If you have loops on bottom, the top needs to pull harder (tighten top tension)
Jamming bobbin case:
If it is damaged from turning out of place once, it could have rough spots on it that makes the thread hang on it, and keeps making it turn over and over. Use a finger nail board (fine sanding) and smoothall rough spots. Then reset the bobbin case taking care to put the notch in the bobbin case in alignment with the proper spot in the machine (basically 5 o’clock) when looking at the round area where the bobbin case goes.

Thread knotting around bobbin case

hello, I had the exact same problem and could not find the solution until i took my machine to my sewing sensei and i solved my tedious problem. It was actually not a tension problem at all but a threading problem. Make sure you have threaded your bobbin correctly and that when you pull on the bobbin thread that the bobbin turns the right way. (mine must spin anti clockwise to work)  Make sure that when you pull up the bobbin thread using the needle that it is not over the feed dogs connective bar but under it. A big problem when the thread gets caught around the bobbin case wheel is that the thread is looped around the feed dogs once and that causes the thread to get caught around the bobbin wheel. In conclusion, thread the bobbin correctly and read over your instruction book before spending the money to get it fixe in s shop.
