We don't have much information to go on, like how is it not stitching. Is the machine actually functioning (needle going up & down, feed dogs moving, is the motor working, is it acting like it's stitching but the threads are not forming a stitch?)

Janome Memory Craft 9000 Computerized Sewing Machine.

sounds like a part is damaged or jamed, the machine needs to be checked
to see what's wrong with it

is the problem the fabric is not moving forward but staying in one spot? which would mean the feeddogs need to be checked to see what position there in --up for sewing---down for darning
or the thread is not feeding into the machine?

it's possible that something has come loose or broken, it needs to be serviced

when the fabric does not move then the feed dogs under the needle plate need to be checked to see if there up or down.
if the feed dogs are down then the lever or switch needs to be pushed up into the correct position
if the feed dogs are up & they are not moving the fabric like there suppose to, cause it's there job to move the fabric against the presser foot,, then they need to be check

the gears that do the zig zag stitches should be checked to make sure there not worn & weather they might need be be greased

The needle on my sewing machine won't move. The pedal makes a noise but nothing happens. The hand wheel doesn't turn either. Please help this is the first time I have tried to use it and disaster

I had that problem too! I usually turn the tension knob and it works,
