Take a look through this comprehensive list of
TROUBLESHOOTING
symptoms and possible solutions, it may also be useful for further reference in other times of need.

Check the timing of the needle to the hook. HERE is a guide to generic principles of Timing



Now also take a more specific look at tension issues....
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....

upper thread will not pick up lower thread and or - 4c76dc1.jpg ...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.
165ca5c.jpg 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

Elna Pro 4De serger thread breaking


Be sure to thread each in the ORDER specified--for most machines (but yours may differ) upper looper, lower looper, then needles. Follow (closely) the threading diagram on the machine. Missing one guide or hitting the guides out of order will throw you machine into a tizzy! On my serger, the lower looper has to lay over the top of the upper looper/thread before it all gets pulled under the presser foot toward the back of the machine.

It also may help to RAISE the presser foot when threading the machine.

Why does top thread keep breaking?


Sounds like your tensions, both upper and lower are out of whack. Easily fixed if so...google a vidyfor your make/model machine on adjusting both upper and lower tensions.

The tread from the lower looper is not being picked up by the upper looper how o i fix this?


Best advice would be to consult your owner's manual. The most common serger problems are caused by incorrect threading or not threading the threads in the proper order. With most sergers, the upper looper should be threaded first. The lower looper is threaded second and the lower looper thread tail should drape OVER the upper looper. Then thread the needles.

Be sure when threading that each thread is pulled snugly into the tension disks.

Bernina 335 serger won't sew/overlock. carefully rethreaded the serger but that hasn't helped.


The 335 has a two thread chain stitch (stitch type 401), and the overlock side (right needle side), is a three thread plain overlock. If you are describing the plain overlock as the problem, I would first suggest the following in re-threading:

1. Thread the upper looper
2. Thread the lower looper
3. Thread the needle last (important)

If the needle threaded, you cannot re-thread the lower looper without breaking the thread.
In order to thread the lower looper, the lower looper must pass by the needle thus picking up the needle thread. So, instead of threading the lower looper thread underneath the needle thread, the looper would be threaded on top and cannot sew without breaking the thread.
Make sure that the threads are bedded between the tension disks. Check this by stretching the thread fore and aft of the tension disks as well as visually noting that the threads are not accidentally threaded behind the disks. You can also loosen the tension disks when threading so as to allow the threads to bed deeply between the disks.
Please reply with your observations.

Needle goes down but don't pick up the bobbin thread. It come up and tell me that my upper or lower thread is cut.


try changing the needle
try rethreading the machine top and bobbin
make sure to use every thread guide-this is improtant for the
thread tension
make sure the bobbin is turned correctly in the bobbin case
also could be a problem with the computer motherboard
or there could be a problem with the timing

I have a bernina overlocker and whenever I use it the lower looper (marked in red) thread breaks. How can I fix this? It was serviced yesterday and when other people used it before me it worked fine!


Then it's one of two things. First try setting your lower looper tension on 3 and see if that works. If not set it back on 4 and cut ALL your threads and re-thread the machine STARTING with the UPPER looper, then the lower looper, then the right needle, last the left needle if you're sewing a 4 thread overlock stitch. Make sure the threads aren't twisted in the thread guide. Make sure the lower looper thread is OVER the elbow on the upper looper and over the upper looper thread. Let me know if this works. We'll work until we get it fixed!

My bobbin thread will not thread. When I bring the needle down, it comes up without the bobbin thread. The mechanism moves, but no thread. How do I fix this problem?


check the bobbin to make sure it's not warped
check the needle to make sure it's not bent-roll on flat surface to see if it roll correctly
make sure the bobbin is in the bobbin case correctly
make sure you have a 3 to 4 inch tail on the bobbin-so the upper thread can pick it up easily
make sure you have a 3 to 4 inch tail on upper thread also as it picks up the lower thread
or you can hold the upper thread with your hand to the side of the machine & use the handwheel to lower the needle as it picks up the lower thread
pull both threads to the back behind the needle
make sure there is no lint or loose threads in the bobbin area

Top thread will not pick up bobbin thread makes a big loopy mess


This is sometimes caused by the upper thread not threaded correctly. You need to thread it first with the pressure foot in the up position. You need to "floss" the thread into the clear plastic guide as this is where the tension is. The tension should be set to E for embroidering. Also make sure you get the bobbin thread in the slot on the bobbin case. Also, lower your pressure foot before you begin embroidering. Hope this helps!
