Question about Sewing Machines
Before you cut, make sure to use the manual wheel to bring the needle down, as if it's about to make another stitch; stop the needle before it touches the fabric, pull the thread from the fabric a few inches, and then cut.

SOURCE: sudden knotting under fabric
I have an Elna 2005 machine and had a similar but opposite problem whereby the tension up top was too tight - thread wouldn't pull smoothly. I found adjusting the feed dog lever slightly helped the stitches a lot, even though the needle tension up top is no better. Hope that helps! :-s

SOURCE: Bottom thread will not catch
Unplug the machine and remove the needle plate so that the bobbin case if fully exposed. Lift out the bobbin case and the cup that it sets in will be visible. Locate the "hook" on this cup. It is a finger with a sharp point at the upper edge of the cup. The hook is what grabs the thread from the needle while sewing.
If the hook catches the thread from the needle, put everything back together and try threading again.

You may have put the timing out, however, try this before you despair too much......
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
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.
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.
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 !
....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
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 !?!?!)
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: Thread breaking.
Rethread the machine following these directions:
all machines thread the same. TTN tension, take up, needle.
Beginning with the spool, guide the thread through the thread guides to the tension assembly. Pull the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.) If it passes this test, continue up through the take up lever,then down through the thread guides to the needle. Make sure your needle is fully inserted and turned the correct way.( If you load your bobbin case from the left side,the needle rule is normally FLAT to the RIGHT is RIGHT. There are some exceptions. If you have a newer style drop in bobbin or your bobbin case loads in the front then the rule is FLAT to the BACK.
Remove the bobbin case and bobbin. Pull on the bobbin thread to make sure it doesn't pull too hard. It should have some tension on it but not a lot. Insert the bobbin and bobbin case into the hook assembly and pull on the bobbin thread again.The tension should still be about the same. If it is tight, you need to look at the bottom of the pin that the bobbin case sits on and see if there are any threads looped around it. If there are , you need to remove them.
Hold the top thread , turn the hand wheel and see if the thread is catching someplace around the hook assembly. If it pulls the thread up easily, put some fabric in it and see how it works.
Make sure the thread is through the take up lever.

SOURCE: Broken needle threader?
Hi - welcome to FixYa. I have this machine, and unfortunately, the cassettes can break. If the threader worked when you first got your machine, I would suggest buying a new cassette (even if your threader is working). A second cassette is very handy because you can thread your next color in the extra cassette before the machine stops for the next color change - when the machine does stop, just put in the second cassette, and thread the other with the next color - speeds things up alot. And, if one of the cassettes does break, you aren't sitting in a puddle waiting for a new one.. You can find the thread cassettes for sale on a variety of sites - this is where I buy mine:
Some of the 270Ds came with a spool pin - look in your manual for a picture and for the instructions for installing and using the spool pin. You can use it for spool of thread that are too large for the cassette and I think you can leave it installed on your machine all the time. If you don't have your manual, leave a comment and I'll look mine and check the instructions.
Hope this helps. If you have a minute, a rating (good or bad) tells me if the information or solution I provide is helpful to anyone who visits FixYa.
If you would like me to write a tip on salvaging an embroidery project that has been pulled into a birdsnest, leave a quick comment and I'll add the tip. Thanks everybody, and good luck. Please feel free to comment if you need more help or have more questions.
