I have a Janome 4000 MC. The bobbin case will sometimes shift to the right so that the plastic nub on it slides under the small metal piece next to it. Do I need a new bobbin case?

It isout of time you need to time it.by adjusting the screw on the bobbin holder turn it left or right and the tension knobe and foot tension.

This is the diagnistics routine for Janome 9000.

Run each test in sequence from 1 - 13, or until you find error

The results of this may not be what you want to hear, and may be why no-one has yet replied....I hope for an easy resolution for you

SOURCE: Bobbin Case

I'm having a similar problem today. I took out the bobbin case and when I went to put it back in, the whole system locks up. I've tired cleaning, changing needle taking the metal plate and piece that holds bobbin case out and put it all back in after cleaning. Nothing. My symptom is I can't get a complete stitch, the needle goes down, the whole deal acts like it will work and as soon as the arm of the bobbin case gets to 8 o' clock on the gears, It jams and won't hardly move. I cannot pull the bobbin case out easily after this. Perhaps there is someone out there that can help us!

ok Sim this is a bit tricky but not to tricky first turn the handwheel toward you until the hook is at one o clock postion then slide the case without the bobbin in into the hook area you may have to work the handwheel back and forth alittle but it should slide in just remember that the case should ride in the rim. also take the needle out first that way you wont get stuck trust me it happiens.

SOURCE: I have a CE-4000 model. In the middle of sewing,

When you put back in the bobbin case, there is a little "knub" that sticks out with a flat spot on the right (on the top side of it) that you need to ensure it rests gently to the left of the position finger bracket (silver metal piece, in the square of the bobbin case area its on the right closest to you).

When you put in initially, it was probably twisted clockwise and there was a gap between the knub and the position finger bracket and when you put the needle plate on in jams that bobbin case in that position and the needle just takes chunks out of it..

You might need a new bobbin case, try sanding out the needle marks with sandpaper.
