How do I wind a bobbin on a ingenuity - Singer 7436 - INGENUITY

First off make sure your bobbin winder is not enguaged, meaning in the left hand position not the right. Also check your handwheel isn't pulled out to the right which would mean your bobbin winding clutch is enguaged.

On the right side is a big wheel and in the middle a smaller one. You need to unlock the smaller wheel so that the needle mechanism does not run when re-winding a bobbin. You need to use both hands to do it. Hold the bigger wheel and then loosen the inner wheel anti clock wise. Once you have finished loading your bobbin you need to tighten the inner wheel again for the machine to be fully functional again.

if it's electronic, it sounds like the clutch has not disengaged like
it should, it might be a good idea to have the machine checked just
incase the machine may need to have some type of adjustment.

Sometimes it is a simple thing like a faulty bobbin, there is a very small piece of plastic that the winder has to catch and if it is worn or broken or just plain faulty then the bobbin will not turn

On some of the singer machines that error means that the bobbin is in the wind position ,., I would chechk the bobbin and make sure it is in the propper position and switches like it is supposed to ..

Take it to repair shop, getting to the problem requires taking the shell cover off the machine, difficult to do, then fixing the problem might be electronic in nature.

1. Take bobbin out and re-insert and thread.
If that dosen't work, try:
2. Take bobbin out and bobbin case, clean area and re-insert bobbin case and bobbin.
If that dosen't work, try:
3. Re-thread the top thread that goes to the needle. (Sometimes the thread dosen't hook to the "Thread take-up"(page 6 on manual). It pulls the bobbin thread and the bobbing becomes loose inside the bobbin case.
If that dosen't work, try:
4. Wind a new bobbin (Sometimes a bobbin might wind thread to lose) Do not wind thread to the edge of bobbin.
If that dosen't work, you should take it in to be serviced...Somenthing might become loose that only a technitian can correct.
Also check manual for troubleshooting.
Good luck.....

Check the clutch at the knob on the right side of the machine, where you tighten it to sew & loosen it to wind a bobbin. It could be very loose and when you start to wind a bobbin, it tightens itself up.

Did you move it to the right?It has to be against the piece above the wheel.

Bobbin will not lock on bobbin spindle, what can I do?
