Janome 9000 seems to be jammed.

Force it hard in the direction of travel using the handwheel. You can't break it. The remove needle and thread and run at full speed for 10 seconds.

I don't know your experience with this machine so bear in mind.

Your "grinding" could be the machines internal slip clutch, but just guessing. Likely you can't make needle move up/down with handwheel or make a full or multiple turns of handweel ?

If yes, then check the bobbin area (hook and race) is not fouled with thread and/or fabric.

If bobbin area is clear, then try changing the stitch selector to see if its jammed as well.

What type of sewing were you doing when this occured?

Comment here and I'll assist further if need be.

Have you tried turning the handwheel and using the foot control at the same time just to get it moving if its humming when you put your foot down its trying to go sometimes a little help to get it going helps it might need some oil or its got a dry spot from being stored give it a go and let me know how you got on.

Did you take it for service? If so, the technician should be able to tell you what was wrong and what probably caused it.

If you didn't take it for service, how were you able to get it to sew again? Could be the fabric was too heavy for the needle and caused the needle to bend. It could be knocking your machine out of time. Be sure to use a heavy needle like a #16 or #18 (and for most fabrics try a "sharp" like microtex, top stitch, leather needle) and sew slowly with heavy fabric. Perhaps the fabric is too heavy for your sewing machine. I sew heavy fabric like vinyl, canvas, etc but I use an old metal mechanical machine that I can help along by turning the handwheel when the going gets tough.

Thanks to floraq803, we have our 11000 working again. The needle threader was stuck in the down position. We turned off the machine, and turned the wheel (which controls where the needle is) until the needle threader bar was straight (approximately 1/2 way between the needle being all the way down and all the way up). Turned on the machine and the threader came back up again. Now back to sewing.

Be sure that it's still plugged in and not on a plug in that is controlled by a switch that got accidentally turned off.

Other than that it is likely that a fuse got blown or the power supply died. In that case take it in for repair.

Have a sewing machine needle handy and turn the machine off.

With your left hand, press and hold /StartStop, Up/Down and reverse while switching on the machine. The screen should display little cross hairs. Using the BLUNT end of the needle NOT THE TIP, press the exact center of the cross hairs. Continue a the cross hairs will change positions on the screen. When finished, switch machine off, wait five seconds and switch back on.

My Janome 9000 has always done that. I can prevent it by raising the needle when I first start the machine, getting it to sew quickly or raising the needle and letting the machine sit for a few minutes. I think my computer wants to warm up a minute. As you can see I.m not a technical person but it works for me.
