It sounds like you haven't threaded the bobbin thread correctly. Remove bobbin, bobbin case. If it is stuck, do Not, do not force the assembly, rather look for tangled threads and calmly snip the thread and remove. Once the tangle is gone, remove bobbin and bobbin case. Rethread it carefully. And contact me if you continue to experience difficulty. Ayou may need step by step directions.
SOURCE: needle picks up bobbin thread but then thread gets stuck
I've had similar problems (as well as other problem with the thread breaking all the time and the "shuttle race" thing that holds the bobbin falling out. One very important thing that isn't mentioned in the manual but that the salesman stressed is that you have to use only "Schmetz" brand needles. They are a tiny bit longer, but that makes all the difference in the world if your stitches are skipping. I forgot and used Singer needles and had horrible results.

Make sure you clean up all the oil......it is not a universal cure all contrary to opinion....
Now, down to business..........
Ensure the presser foot is firm enough for the fabric you are using and that it will not just pull through easily by hand with the foot and feeddogs together (as the needle ascends), or things will not proceed, and you will be stitching in the same spot.
Generally a setting of 3 seems to work for general purposes, but if you are using very light or very heavy fabric, a sample is always a good idea before you start in earnest....also match the needle to the work for best results.
Ensure that all is clean and free of lint jams....now for tension troubleshooting .......
This solution is for tension problems...if you cannot form any sort of stitch, the issue is quite different, so please let me know if you need a different problem solved.....
It is quite long, but just work through each section in order.
The "knotting up" can reveal a lot. If you have loose threads on one side or the other, the tension on the opposite side will be the culprit.
QUICK SUMMARY FIRST:
Ensure sharp new needle,
Thread guides and Bobbin are Clean & Clear of lint
Set Top Tesion to 4 ....then....
Balance Bobbin to suit.
TOP THREAD TENSION:
If the looping threads are on the underside as you sew, it is the top tension. Top tension ought to be between 4 & 6 (this variation to allow for the different weights of fabric in your
projects).
IS YOUR NEEDLE SHARP ?
If you are using a needle that has seen quite a deal of work, or you suspect it may be blunt, change it for a new one !
TOP TENSION & GUIDES:
Make sure that when you thread the machine the presser foot is up so the thread goes between the discs and not to one side, top tension between 4 and 6, and that you have threaded through all the guides, including the last one, usually on the needle arm, just above the needle clamp.
It may be there is lint trapped between the discs, this will keep them slightly apart and reduce the actual tension, sometimes dramatically.
If tensions appear correct, and the thread is definitely in the channel between the discs, but still too loose and looping, try raising presser foot and remove your thread.
Now, with a 2" (50mm) wide strip piece of fabric 8 - 10" (20 - 25cm) moistened with methylated or denatured spirit, gently insert the fabric strip and clean between the discs with
a see saw / to and fro action.
In the worst cases, gentle use of a needle to pick & remove the jam may be necessary, but be very gentle and make sure the tension is set at Zero and the presser foot is raised, (to
disengage tension plates).... do not gouge or score the plates, they need a polished surface to work correctly.
BOBBIN TENSION:
Far less common, but if the loose threads are on the top, it is bobbin tension that is loose, it too may have lint in the spring and be giving a "false" tension.
I would not recommend fiddling with bobbin tension without good reason, it may end up with missing small screws and spring pieces, however, you can take the needle plate off to clean
the hook race area (where bobbin case sits)
...this is just good housekeeping, my wife does this every time she replaces the bobbin....
just take it out and clean the bobbin case and the fixed metal hook race with a small brush to remove lint. If there is a significant amount of lint, use a vacuum and small brush to get the worst.
Then wipe all this area with a cloth or cotton bud (Q tip) moistened (not soaked) with methylated spirit, especially if there appears to be fine dirty deposits....oil and lint combine to conspire against you.
If it seems likely that you ......really ....do .....actually .....need .....to adjust the bobbin case, first check there is no lint trapped in the metal spring where the thread is tensioned.
TOP LOADER:
Drop-in Bobbin case will look similar to this image with the tension screw in the middle of the metalwork....
...the other screw at one end is holding it all together, so beware....it is not a tragedy to undo the whole lot and clean it, but very gingerly and lay the bits out in sequence and orientation, or you risk tearing your hair out !
FRONT LOADER:
....this is a bobbin case from a front loading machine and works in a very similar fashion to the top loader with drop in bobbin, again, if you dismantle it, take care so you can put it all
back properly.
FINISHING UP
GETTING THE BALANCE RIGHT:
When you are certain there's no trapped lint in top tension or bobbin, set the top tension to 4 and the bobbin tension to a point where you just begin to feel resistance.
Try using good quality thread of contrasting colours so you can more easily spot the changes.
Set your zigzag to one width less than maximum (eg. 5 of 6 ...or... 4 of 5 etc) and sew a sample for a few inches and check the result.... adjust the bobbin tension screw very little at
a time, perhaps 1/16 of a turn.
You may find you are playing with this balance for some little while and if you are putting the needleplate on and off each time begin to think it cannot be correct to do this.....BUT....it is,
and eventually, you do get a "feel" for the correct tension and then it happens quite quickly.....as a user you won't be doing it very often unless there is lint built up (or are there small hands at work around the house !?!?!)
OTHER ISSUES:
If you live near the ocean as we do, salt air can play havoc with metalwork inside and out, so to help minimise this, keep a few small packets of dessicant (silica gel) in your machine
case....no case ? then make some sort of cover !
Same applies in any damp or humid environment, keep your machine dry and dust free.
Budget for a proper full service every couple of years (more often if heavily used) and if you don't use your machine for a few years, be aware that old oil will dry out and combining with
dust and form a "clag" like glue (another reason for some sort of cover, even a teatowel !)
FINALLY, A WORD ON THREAD:
If it is worth spending the time, energy and money on making something that you would like to give lasting enjoyment......use quality thread, .......it may seem to cost a little more at the
time, but the results, ease of use and added longevity will be worth the extra, and as a bonus, your tension troubles may be fewer and further between, because there is a more consistant diameter with good thread, and less compensating to be done by your tension plates and less thread breaks !

SOURCE: my thread gets stuck down in the bobbin area.
Ensure that you are threaded correctly, set your tension for roughly 4.5 and "floss" your machine when threading by grabbing the thread by the needle immediately prior to threading the needle with your left hand, and the thread on the top by the spool with your right hand; then pull the thread back and forth briefly.
Ensure that your bobbin is in the bobbin case in the correct orientation.
Ensure that your feed dogs are in the "up" position. Many inexpensive machines do not have the option to drop the feed dogs, and I believe your kenmore to be one that lacks the option, but consult your manual just to be sure.
Also make sure you're using a good quality thread. Use a European thread, and definitely avoid anything from the dollar bin or any kind of "dual duty" type thread. Cheap thread causes nasty nasty things to happen to sewing machines.
If none of these fixes solves your problem, let me know; but going through the above will solve 99% of problems like you're describing.
Good luck,

SOURCE: won't catch bobbin thread
In order to see whether or not my euro-pro 9110 had a timing issue, the service rep had me change out the needle (making sure I was using anything but a Singer brand needle--they do not work in these machines). I re-threaded the needle, took out the bobbin casing and the plastic ring encasing the bobbin, then lowered the needle to see if the hook on the metal ring holding the bobbin actually catches the thread on its own. If it doesn't catch, it's a timing issue and needs repair. They can walk you through this process of troubleshooting and set up repair if need.

First suggestion, rethread both top thread and bobbin thread. Also, it sounds like the thread in bobbin is not right. Make sure u have bobbin seated in right direction. Check manual. Then make sure thread is being guided through any other areas correctly. If this is a vertical bobbin then position is most important as well as running it through bobbin case correctly. If it is top drop-in bobbin, make sure the bobbin is seated in right direction, then the thread is positioned through the flat metal that surrounds the bobbin. If this doesn’t help. Let me kno.
