My bobbin on my Janome 9500 doesn't work. I took everything out and cleaned it and replaced it. Now it only sews a couple of stitches and jams and makes a birds nest and I have to take out the needle plate to clear the jam. Is there a diagram anywhere of how the bobbin case is supposed to look? I cant tell if anything is bent because I don't know what it is supposed to look like.

In this video I show you how to thread a Janome sewing machine ... I've unwrapped it and started reading the manual and it wasn't easy to see ...

I had the same problem with mine I had to take it in for servicing

This was really helpful for me fixing my daughter a John Lewis (janome) mini sewing machine, and now can get the bobbin thread up again, however, when you sew, the thread is not staying in stitches, just coming off the material completely. I tried forcing the gears on one more time but then it didn't pick up the bobbin thread again so went back to the other gear position. Any ideas of what to try and get it stitching again? Thanks

Try loosening both top and bottom tension. while longer stitches are easier, it can be done on shorter stitches as well. A bennifit to shorter stitches is the gathers will be smaller and easier to work with! Remember to reset the bobbin tension before sewing again.

try these suggestions
change the needle
make sure the thread doesn't come off the thread take up lever--this
can jam the machine
make sure the bobbin is turned the right way in the bobbin case--this
can cause problems if the bobbin is turned the wrong way
make sure the bobbin is not warped or damaged
make sure there are no burrs in the bobbin area or on the needle
plate

have you changed the needle lately?
have you tried rethreading the machine?
when was the last time it was serviced?

Has the bobbin case dislodged and moved? there should be two red marks one on the bobbin case and one on the outer holder, are they lining up? Sometimes as these cases are held by a magnet, they will get dislodged and move slightly, especially in a jam up.
Take out the bobbin case and clean under it, then replace it matching up the red marks.



If the bobbin case has actaully been struck by the needle during a dislodgement, it may well pierce the bobbin case plastic, look for burring or marks on the outer flange area. If this has occured, the thread may catch on the burr as it comes over the bobbin and jam again.

You can buy a new bobbin case if yours is damaged or maybe just file the burring with an emery board (remove it from the machine first of course).

Lastly, check your needle hasn't been bent, burred, or put in backwards, any of these can prevent a stitch from forming.

If all the above fails, then it is possible that the timing has been knocked out and you will need to get it serviced by a technician.

Recheck the bobbin to be sure the thread is feeding from the bobbin spool in the correct direction and through the proper guides.

Re-thread the machine with the presser foot up.

Make sure the needle in inserted with the flat side to the back of the sewing machine.

Have you tried a new needle?

If re-threading, changing the brand of thread, etc. does not work, then it's likely your machine is out of time. Search for sewing machine timing or take it for service.

The solution that I found last night was the thread tension. I have never touched the dial, only had it set on 'auto." When I started playing with it, I realized the top thread should be really easy to pull through the machine and it wasn't. I started turning the dial (to 3 or 4) and the thread slid through the machine perfectly. No more birds nest! I really thought it was bobbin initially because of the horrible sound it was making.
