Once you have the thread guided and the bobbin is on the thread winder spindle, push the bobbin to the right. The machine will not sew again until the spindle is in the left position.

Please TRY the solution BEFORE giving your considered rating.
Specific detail on bobbin case adjustment (with picture) near halfway down reply, the remainder will help you achieve a balance of top and bottom tensions.
Ensure that all is clean and free of lint and jams, this is the most likely cause....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 consistent diameter with good thread, and less compensating to be done by your tension plates and less thread breaks !

SOURCE: will not pick up bobbin thread
Unusual for this machine. Check to be sure the needle is inserted with the flat side to the back of the machine. If it is, remove the needle plate, bobbin and bobbin case. Turn the hand wheel slowly toward you and see if the point of the hook is above or below the eye of the needle when the hook point is aligned behind the needle. If the eye is above the point of the hook the machine is out of time and best taken to qualified technician.
SOURCE: How to thread bobbin in a Janome 415?
Here is a link to the manual that shows how to thread the bobbin. :)

SOURCE: I just bought a janome mini sewing machine. I
First, in order to get the bobbin thread up, you have to turn the wheel backward, not forward. If you try this, and it is not the problem, keep going.
Next you need to check the needle. There is a screw on the right side of the needle carriage right underneath the underside of the top...unscrew this and the needle should come right out. The flat side of the needle shank should go towards the back of the machine. If it isn't, switch it so that it is and try again.
If this doesn't solve your problem, what has happened is that the gears in the machine have gotten out of alignment. There is an easy fix:
Take off the plate that covers the bobbin chase...there are two screws one on each side. Remove these...you need a stub screwdriver, because regular ones will not fit under there.
Remove the bobbin carriage and the bobbin, making careful note of how they fit back in. Take a picture before disassembling it so you have a reference.
The part that carries the thread around the bobbin is still in the machine. Turn the wheel and you will see it rotate. What has happened is that the needle is not going down in the machine at the right point because someone kept sewing after it jammed and one gear kept going while the other one didn't and now it is out of alignment. These machines have plastic gears and the can slip past each other if you aren't careful not to stop immediately when they jam.
To fix it, you are going to have to do some trial and error. Grab the rotating part of the bobbin chase and hold it firmly. Rotate the wheel forward until you hear it click once. Then rotate the wheel backward again and see if it grabs the top thread. If it doesn't, repeat holding the bobbin chase and turning the wheel forward until it does.
Once you have the gears basically aligned, you will need to reassemble everything. Put the face plate back on and put at least one of the screws in all the way. The face plate holds the bobbin chase in correctly and if you don't fasten it it will not work correctly.
Now try sewing. If it starts to jam, stop immediately, cut the threads and look at the back. If it's a loopy mess, you are going to have to dissamble as before and again grasp the bobbin chase and turn the wheel forward one more click, then reassemble and try again. Eventually, you will find exactly the right alignment and the machine will sew perfectly.
I just had to make this fix on my own machine...I didn't want to take it in for repair because the bench fee alone would cost as much as the machine did!
There are some great video's on YouTube for help with threading the machine...look for StampTV and you should find them. Good luck!
