Question about Janome Sewing Machines
Upper thread keeps snapping. I have checked tension, rethreaded, it's good Guterman thread, bobbin in correctly .. sews for about 30 secs and then it catches in something in the threading process and snaps .. it's a brand new machine .. but I really want to get started!! Any ideas?

SOURCE: 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.

The tread only breaks in the needle. what can i do . i don't get to sew anything . I tread the needle and get everything ready and start the machine and as quickly as that the tread is broken and the machine has not sewn at all.

Hi! Did you by chance, change your needle? If so, make sure you have the flat side of the needle shaft facing the correct direction. If the needle isn't in all the way or the flat side of the shaft facing the right way, the bobbin thread won't pick up.
Let me know if this helps, ok?

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.
