When I turn the knob for changing the needle position, the needle position does not change.
SOURCE: Needle wont go up or down
If the Handwheel (big knob) is moving but the needle is not moving, you need to engage the clutch ........depending on the model
- push handwheel in to engage, pull out to disengage
or
- if there is a smaller wheel inside the handwheel, tighten to engage, loosen to release.
BUT if all is jammed........
Check for threads that are jamming the motion of the hook around where the bobbin case is
If your bobbin goes in from the top, remove the needleplate and bobbincase remove thread jams by gently rocking handwheel back and forth until released.
Clean around the hook race with a rag moistened with methylated spirit, surgical spirit or similar, then reassemble.
If front loading, open the door for bobbin case area, release 2 retaining clips holding the collar on (take note of the position/orientation for when you re-assemble....even take a digi photo to refer to !?!).....
......then just do jam removal & clean out in much the same way as for the top loader.
In all cases, don't force too much or be too brutal, gentle and patient works best, try to judge where the jam is caught and work with it slowly......you may need to cut jammed threads, just ensure all are removed before you re-assemble.

I'm giving you a direct link to the Manual on page 82 of which is explained the procedure of removing the needles so you can attach new ones the same way...

The small hook that passes through the eye of the needle is bent or broken. If it is only bent it can be straightened with a small screw driver. If it is broken it will need to be replaced. Most dealers can get this part for you for about $5.00
