Bobbin thread jam

Could be: Blunt needle, wrong size needle, wrong thickness thread, old thread or it is not threaded exactly. Hope this helps.

If you mean that the needle has jammed with a build up of thread, then the only option is to cut the thread, raise the needle, if you can, and remove ALL pieces of cut thread. Sometimes if it's really jammed, you need to use a sharp knife, horizontally, to slice through the jammed thread.
The bobbin should be removed after this, and ALL traces of thread removed from all areas. Then, re-thread, re-insert bobbin, and try again.

try changing the needle
rethread the machine top & bobbin
make sure the bobbin is inserted correctly in the bobbin case
make sure the top thread is not coming off the thread take up lever
make sure the bobbin is wound correctly
if these suggestions don't work, I suggest that you take the machine
to a sewing machine shop to have it checked

Is your top thread tension on 1? this sounds way too loose, should be 4 or 5.
This is a horizontal top loading bobbin machine isn't it like the Janomes?

Do you have a manual for it? It sounds to me like the top thread is too loose and as it is pulled down and around the rotary hook there is no tension on it to pull it back up through the fabric and form a stitch which is then causing it to jam. Then once youve gots bits of thread in there, its just jamming and jamming. Cleaning out the bobbin holder as you described is good, you may need to do it again and ensure all bits of thread are out of it.

I think you need to revist all the threading up and ensure that the top thread is under tension, try number 5. Also check that bobbin is correctly wound nice and smoothly, then loaded into the bobbin holder correctly so that the thread is coming off the bobbin spool in the right direction, ie thread needs to come off the bobbin, then reverse direction in a "v" shape, usually in the direction of the back of the free arm. And that the thread has been clicked into the tension spring fully, put the thread into the slot of the tension device and press down on it with your finger tip until you hear it click into tension.

Also double check the take up lever, if the thread has slipped out of this, it will jam up for sure.

If you don't have any manual for this then try www.sewusa.com, there is good troubleshooting tips and threading diagrams for lots of makes and models.

Hope this helps you, persever, its most likely threading/tension issues and can be overcome with the right settings.

It sounds like it is not threaded properly through the tension disc. Try rethreading and make sure the presser foot lever is in the up position. If it continues, once threaded and with the presser foot down, pull on the thread through the needle. If it has resistance, it is threaded properly. If it pulls easily then there is a problem in the tension area. Check to see if there are peices of thread broke off in between the tension disc.

Sorry I do not have a solution but my Euro-Pro 1925 is doing the exact same thing yours is. Are you also getting a clicking sound and loose stitches on the bobbin side of the fabric? If you find anything out please let me know and I will do the same. I love my machine but I will never own another Euro-Pro product. I think the company sucks and does not stand behind their products. You can not find anything on the 1925 model and no one that can service it either. Thank you, Erica my email is [email protected] Funny thing is my machine is only 3 years old.

Take the bobbin carriage out and clean it really good. Use the little brush that comes with your machine and brush everything. When m y machine jams up like that it usually means there is lint or thread caught in the bobbin carriage.

well i have done the same thing , all u need to do is if you see the screws that hold the bobbin area you un screwq thoes and get you a pair of scisors and cut around the knoted mess and all you do is work with it until it is all out and you dont realy want to pull on it to much you know just work it around so it gets lose so that you can cut it out thin you put it back together and try it out.

Are you making sure that your pressure foot is up when you thread the upper thread? If it isn't then your thread is not seating correctly in the tension disks. It will then be loose and make a birds nest(mess) under what you are trying to sew. The other thing to check is which way you are putting the bobbin into the bobbin case, different machines do it different ways. Some want the thread to come out of the case in the same direction as the slot on the case and some want it to come off in the opposite direction.

Guest,
Probably when your son broke the needle he knocked it out of time. You will need to have a sewing machine technician to repair that.

Hope this has been helpful for you bothl Liz M

Amy,
did you solve the problem with your Jubilee?
I would suggest that the problem may be not holding the two threads at the back of the needle plate with starting each new seam. Elnas really need you to hold the threads, don't let the tail get caught and pulled back into the bobbin holder area. Once you have one jam, you'll have minute threads you maybe can't see caught under the ring guard (black bit) and the jamming will keep happening. Also, make sure you only use Elna bobbins always with holes on the top.

If you've still got the Jubilee and are having issues with it, feel free to add more info, the other contributors comments about the bobbin being faulty are valid but I dont think your machine is worn out, just jamming. You can remove the bobbin holder yourself and clean underneath it and once you've done it once, and know how to line it and the ring guard back up, its pretty easy and will ensure that the bobbin area stays clean.
