Turn your machine off and leave it off. Remove all bobbins - in the machine & from the pin. Remove all thread - from threaded machine and bobbin thread path. Clip the machine thread at the spool and pull the needle thread towards yourself. Clip bobbin thread at spool and close to bobbin, then pull towards you through thread guides. This keeps the tension where it belongs. Move the bobbin winding shaft from normal sewing back to winding bobbin a couple times. It should click in place when moved to the winding position. Check to see if there is any thread that has slipped under the bottom of the bobbin and wound itself around & under the bottom of the shaft. Carefully unwind to clear. If the shaft does not easily move back to the sewing position it is probably stuck in the winding position. Don't force it, but try to get it out of the winding position. Leave it to the left in the normal sewing position (unclicked). Check to see if there is any thread caught anywhere along the path from spool to the winding pin. Pay close attention to the first thread guide and the two discs the thread slips between that control tension. Hand wind the wheel on the right towards you to raise and lower the needle a couple of times. Stop with needle in highest position. Do NOT wind hand wheel backwards (away from you). Make sure the bobbin pin is not in the winding position. Now turn on your machine. Needle should jump to default position. Move the stitch length and stitch width guides to the far right, then far left, to attain the green lights. Press the reverse stitch button to raise lower and raise the needle. It will stop in the highest position. If you still have the error code - make sure the bobbin winding pin is NOT in the winding position. Remove the needle. Lower the presser foot and run the machine without any thread a bit. If the needle bar does not go up and down most likely the bobbin pin is stuck in the winding position. If the code has cleared use your manual to carefully wind a new bobbin. Make sure you are using a 15J bobbin which this machine requires. It will not work with just any bobbin. Next, raise the presser foot then carefully thread the machine. If you don't have a manual you can download one from the Singer website. You might consider cleaning the entire machine paying special attention to the hook area and feed dogs while the power is off. If you find a lot of lint do this more frequently to prevent buildup. Take special care when replacing the bobbin care. Hope this helps. If not call Singer. It may take some time but you should be able to reach someone to help you troubleshoot. If this is an older machine I recommend taking it for repair yourself instead of sending to Singer

Check the bobbin tension and that the thread is tight around the bobbin. Make sure that the bobbin is in the right way around - the bobbin thread should double back on itself coming out of the bobbin holder.

If the bobbin case is defective this can cause the problem. However, this can be a difficult problem to repair, take it in and ask for an estimate to repair.

Machines that stop the bobbin winder automatically when the bobbin is full have a mechanism that detects how much thread is accumulating in the bobbin while it is winding, then stops the winder when the bobbin is full. It is likely that the bobbin winding mechanism needs to be adjusted by a mechanic. 
On the other hand, if the thread winds evenly, and stops winding when the bobbin is about 3/4's full each time, you probably don't need to worry about it if all else is good (even tension, consistent stitch quality, and so on). 
If you'd like me to post some general troubleshooting tips, let me know.
Good luck

Your machine could be defective. Take it back where it was purchased.

My Singer 7422 seems to be jammed. When I start to make a stitch, the thread from the needle gets caught on something on the bottom and the thread goes over the bobbin.

Threading the bobbin - winding thread onto the bobbin.

Position the new empty bobbin onto the vertical bobbin rod next to the end wheel. Click the rod to the right to engage drive. Hold the outer end wheel with left hand, and rotate the inner wheel anticlockwise by about a 1/2 turn (it stops) this removes drive from the foot and needle mechanism.

From a spool of thread on the top, thread to a loop/post on the left on the top. Then back to the bobbin you want to wind. Thread through a hole from the inside-out. Hold the thread vertically above the bobbin while you depress the footswitch to start winding. Let go when it's turned a few times.

Move bobbin shaft left, and tighten end wheel after winding enough.

Fitting bobbin-

Move footplate towards you, insert bobbin in hole so that bobbin rotates anticlockwise when thread is pulled, then pull thread into the fine notch towards you. After this position thread away from you, and slide the footplate closed.

To start / load thread. Hold the end 3" of the thread through the needle behind the sewing foot. hand crank towards you to sew first stitch in air. This should retrieve the lower thread - which you can catch with a handy pair of scissors. Then pull both threads rearwards - ready to sew.

Had the same problem as mommyb2 - it was the bobbin spindel was in the wrong position. Push bobbin spindel to the left and it works for sewing.
Have the same problem winding my first bobbin - pushed spindel to the right to engage bobbin fuction and the machine locks up and wont wind the bobbin. Irig did you bring it in for repair? I'm thinking its broke - which **** as mine is a brand new machine
