Re: Sew Smart Bottom Threading Problem
There seem to be a number of folks with the same machine - same problem - stitches won't form. Unfortunately, this many of the same machine with the same problem would tell us to return it and look for a different brand/model. We can only suggest the same - but have posted the following for you all to try (posted individually for another reader earlier this morning - just discovered the multiple same issues):
A few things to try:
Loosen the needle screw, make sure the needle is fully
up in the needle hole and re-tighten the screw. Vibration can sometimes
cause the needle to slip...and the needle not fully inserted can cause
Make sure the bobbin is turning the proper direction.
If your machine has a standard bobbin case that comes out of the
machine, turn the case so the bobbin is facing towards you. Pull the
thread tail and make sure the bobbin turns clockwise. If it's turning
counter-clockwise, flip it over and try your machine again. If your
machine has a drop-in bobbin, double-check your particular machine
instructions to make sure it's going the right direction (clockwise or
counterclockwise depending on the machine).
Make sure you have tension on the upper thread. Do
this by lowering the presser foot (make sure the thread tail is NOT
under the foot) and give the thread a tug. You should feel tension on
the thread. If not, the thread isn't fully down in the upper tension
disks. You should be able to give it a further tug to pull it down into
the disks. No tension on the upper thread can cause the stitches to not
If none of the above seems to help, you'll need to get
your dealer involved (provided you purchased your machine from a sewing
machine dealer). They can determine if it's just something happening
during threading or if the machine is out of timing. They are there to
help you before AND after the sale and should be willing to take care
of whatever is happening.
If you did NOT purchase your machine from a dealer,
and the store you purchased from does not have a sewing machine
technician, we would suggest that you return/exchange it for a new
machine and see if the new machine has the same problem (most
department/big box stores that carry machines have a very liberal
return policy since they do not have personnel dedicated to sewing machines).
If the new/replacement machine has the same issue, we
would suggest you return it (no sense frustrating yourself) and perhaps
find a local sewing machine dealer to purchase a machine from.
Authorized sewing machine dealers are geared towards providing machines
and service (before and after sale) and are worth the extra $ for the
peace of mind and knowledge that you'll have someone local to call on
Best of luck with your machines - we hope it's
something minor and you're up and sewing soon! Don't hesitate to reply
to this post if we can offer further help, ideas or suggestions.

try rethreading the machine--use every thread guide make sure the top thread has not come off the thread take up lever change the needle --make sure it's the right one for the fabric being sewed make sure the bobbin is turned the right way in the bobbin case if the bobbin is a front or side loading also make sure the bobbin case is inserted correctly into the machine if none of these suggestions help then the machine needs to be checked to see if it's a timing problem
Take it back while its under warranty and ask the dealer to thread up and sew on it; this way you can establish if it is a faulty machine or if its some other variable causing it. Certainly if you are an experienced sewer and have used other Singers, then you would know if you've done it correctly and your instincts tell you the machine is faulty so I'd suggest you take it back to the store.
A sewing machine operator can often help themselves when their machine does not operate properly. Here are some simple instructions, which if properly used can save time and mechanics service calls.

It is in your top threading not in the tension discs right. Totally rethread as per your manual, now with the presser foot up, pull on the top thread, it should feed smoothly, now put the presser foot down, pull thread and it should barely move. Sometimes that seat the thread in the tension discs right. Read your manual and it will answer lots of questions for yopu. Hope that helps you.
take thread completely out. rethread, pull your foot lift up before threading. make sure thread is in the tension disk of you dial and notice if thread is a little tougher to pull when u put foot down...
Try threading the machine with the presser foot up and see if this helps.
When the foot is down during the threading, the thread does not enter the tension control as it should, then when you start to sew, the upper thread has no tension and does not form a stitch with the bobbin thread.
Thread looping on the bottom means you have a problem with the top thread. In your case there is no tension on your top thread. Take all the thread out of the top and start threading over. Make sure you follow the correct path and make sure the thread goes through the tension discs. Then at the time of sewing, make sure your foot is down (this closes the tension discs and gives the thread the tension.) You may have worked on the tension setting while not realizing the thread was not in between theses discs, so also make sure the top tension disc setting is in the average before sewing.
(If you see loops on top, it means you have a problem with the bottom thread)
In most cases when thread is nesting, bunching, ect..it is a result of top threading. Be sure that you have the thread through the proper threading guides,most importantly, the "take-up lever" (that is the silver hook that moves up and doen in time with the needle). This should resolve the problem regardless of the machine.
