I have a model 1409A White sewing machine and I'm having issues with threading it. Something is going on with the needle and the bobbin. How do I fix it?

Incorrect threading.

Bad tension settings top and bobbin.

Bad quality thread. Cotton can go rotten as it is organic.

it is a SEWing machine
the bobbin is just a spool for thread and does b nothing more
make sure that you have installed it correctly so that the thread comes out in the right direction
next check the needle / hook timing as that is critical to the sewing machine operation

First thing to try is a brand new needle. A bent/damaged needle may not be able to pick up the bobbin thread.

Otherwise, it is possible it has a timing issue, ie the needle is arriving at the bobbin at the wrong time in order to connect with the bobbin thread. Search the internet web sites and videos. There is a lot of information on how to fix sewing machine timing. Or take it for service.

Sounds like you might have multiple issues going on with your machine. Possibly the machine's reverse mechanism is stuck and the needle/hook may be out of time. The timing is when the needle arrives at the bobbin at the correct time to connect with the bobbin thread. (Be sure to try a brand new needle as a bent needle will sometimes not pull up the bobbin thread.) You can search the internet for information and videos regarding both issues and possible resolutions. Other than trying to fix it yourself, you can take it for service.

Sewing Machine Timing Demonstrated

Sewing machine only works in reverse

The methods may vary based on your machine brand & model (ie some recommendations using oil probably would not be the best for a computerized machine).

Are you holding the end of the top thread whilst trying to pickup the bobbin thread? Put a BRAND NEW needle in - it may look OK, buy the slightest bend will be an issue. Is it the CORRECT needle for you machine? - check your manual. Is the bobbin in the case correctly and feeding out the correct direction? ...... timing may be out. Good luck

try these suggestions
change the needle--use needle according fabric being sewed
rethread the machine top & bobbin
clean under needle plate & in bobbin area for lint or threads
make sure the bobbin is not warped or damaged
make sure the bobbin case is not damaged
if none of these suggestions help, then I suggest having the machine checked
to see if there is something wrong with the inside parts

Check the model number of the machine. White sewing machine manuals are available from Singer at http://www.singerco.com/accessories/instruction-manuals . Enter the model number and click Search.

Unlike some machines this one doesn't really need the bobbin threaded. Place the bobbin in the bobbin holder and leave about 5" of thread extended out from the bobbin holder. With the bobbin compartment still open, lower the presser foot and turn the handwheel to move the threaded needle through the stitch cycle. (I find holding the threads helps; normally, you'll feel them pulling under your fingers.) When the needle has returned to the top of the path, lift the presser foot. Then pull both threads around to the front (the bobbin thread should wrap around the top thread). Then move the threads to the back of the presser foot.

If the needle isn't catching the bobbin thread, first try a new needle (bent or dull needles don't always function properly). Next check the bobbin holder for nicks or other damage. There is a small hook on the bobbin holder that should be where the top and bottom threads intertwine. Under rare circumstances, you will find that the bobbin tension of the bobbin holder is misadjusted. This can interfere with the bobbin thread twisting properly. There is a little set screw that allows you can tighten or loosen the bobbin tension as needed. Adjusting the screw is to be avoided when possible and done in small increments (1/8 turn) if needed. It's easy to strip the threads for the set screw and end up needing to replace the bobbin holder.

I hope this helps.

completely unthread the machine....ensure the needle piston shaft is in the correct position and retread the upper. reinstall the bobbin and turn the machine by hand to engage the bobbin thread. Draw the bobbin thread through the stitch plate and with the needle thread, allow to trail off the back. attempt to sew a piece of scap material.

please let me know what happens at this point.

This is something that is very delicate and requires experience to fix. It is a timing issue and sorry to say you are going to have to take it to a sewing machine shop to get it fixed. in most cases this is a small charge around 50-80 dollars to fix.
it would be way to complex and long to put everything here to fix it yourself.
