Thread wadding up in machine

I've had my machine for about two months without a problem. Lately I've been sewing and it's been fine, and then the thread starts wadding up. I've tried un-threading and re-threading it and the whole problem just starts again. I don't know what to do. Can someone help me?

What do you mean you are unable to pull the bobbin thread through, elaboration would help solve the problem...
I suspect I'm having the same problem with you if it's anything to do with the top thread looping around in the bobbin holder.

Damn machine!

Your machine is out of time and needs to be serviced by a technician.

SOURCE: 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.

Make sure you are threading the machine correctly and it has the proper tension. Also check the bobbin the thread has to go thru the little lash

is the bobbin thread in correctly( meaning is the bobbin thread in the lower tension) if it is and the top thread is in correctly and make sure the feeddogs are in the up position if all of these factors are alright then it will have to go to a local dealer to get taken care of

Why is the thread catching on the tension discs on my Singer 5430C machine

Have you cleaned your discs lately? Thread has wax applied to it believe it or not. Take a sturdy piece of cloth, fold it over and "floss" the tension discs. Test the stitch again. If that does not solve your problem, then the discs themselves may need replaced.

More than likely it is your top threading that is not right. Try seating the thread in the tension discs. To do this, rethread, now with the presser foot up, pull the thread, it should feed smoothly. 'After this, put the presser foot down, it should barely move. Hope this helps.

Try using a style 60 or 66 bobbin. I had the same problem at first, and someone on-line suggested the different bobbin. I use a style 66; instead of having a flat bottom and top (and all those holes), it's shaped something like a bagel. Now my machine works beautifully.

Hi, I'm guessing you have the bobbin in the bobbincase upside down and its turning the wrong way. Or the machine is not thread correctly. Possibly there is junk in between the tension discs at the top that the thread goes between. Just some thoughts.

Thread wadding up

Tension!!!! Its all about the tension! I just had this issue after loosening my tension. So tighten it - the higher the number the tighter the tension. My tension is set at 6 on a Singer 9005 and it seems to work great. By turning it down to 4 I ended up with huge loops/wads of string. Hope this helps!
