SOURCE: Machine not sewing

Make sure you have threaded the machine from right to left, it sounds like the needle thread is trapped under the lower looper thread and cannot form a stitch.........start the threading over from scratch like this:

  1. Lower Looper
  2. Upper Looper
  3. Left Needle
  4. Right Needle
Is there a diagram for how to thread on the inside of the door ?

Follow that slowly and carefully to make sure you have not missed any thread guides on the way, as each one needs to be followed through to ensure correct tension and thread progression.

If you are certain that all threaded correctly, did you have a fabric jam and pulled it loose ? If so, the timing may well be affected.

Post an update and we'll get this right.

SOURCE: bobbin thread bunches up creating a tangled mess under the plate

This could either be due to the bobbin being wound too loosely, or the tension on the top thread is too loose. This just happened to me the other day, and I thought it was the bobbin thread, but then I put another bobbin in with a different color than the top thread (this is a huge help in diagnosing thread issues), and I was surprised to find that it was actually the top thread that was a big loopy mess on the underside of the fabric. I fixed it by tightening the tension on the top thread (quite a bit), and everything was fine.

SOURCE: Top thread won't pick up the bobbin thread

re insert the needle, maybe you did not put the needle up as far as it is to go. Make sure the flat side of the needle is to the back of the machine. Without any thread in the machine hand turn the wheel and look to see if the hook of your bobbin would/could catch the thread (to see if timing is right)
then thread the machine and hand turn the wheel and see what it is doing.
Your timing might be off, but I do not think that is likely. Though it is possible that when the needle fell out, it hit something hard, broke, and pushed the machine out of timing. then you need to bring it in.

SOURCE: top thread keeps breaking

This sounds like a backwards needle. Take out the needle and when you re-insert it back in, make sure that put the flat side to the back.

Search the internet for:

Manufacturer + Model + the word "Manual"

If one or more threads are too tight, loosen those tension disks. To start out, set all tension disks at the halfway point between the high and low numbers, then adjust from there.

Why won't my Bernina Activa 140 sew the blind hem stitch?


Are you absolutley sure you're not getting a problem with stitch formation on, for example, wide zig-zag. Check again, using a different colour top and bottom and make sure that the stitch is being formed properly with only the top colour on top and bottom colour on the bottom. It sounds as though the bottom loop is not being picked-up by the hook properly. Make sure you've thoroughly cleaned-out any fluff under the stitch-plate and remove the hook/shuttle and give the hook race a good clean and give it a single drop of oil, even if you've got the lightweight part-plastic hook/shuttle fitted.

The lower thread does not bring up , so that the uper thread does not come in contact with the lower thread .I hear unusaul noise while sewing.All these happend when I tried to sew a jeans .i used a thread...


As a general rule, domestic machines don't like buttonhole twist, that heavy yellow thread you see on the RTW jeans. Sometimes you can put it through the bobbin but use a regular weight thread on top but this means sewing upside down as you'll want the yellow on top. And lots of machines dont like different weight thread top and bottom so it just makes for awful stitching anyway.

Best solution to top stitch jeans is use a regular weight thread, large size jeans needle but thread up two spools of thread on the top with both threads going through the same needle eye. It still may not solve the problem though.

To your machine, firstly change the needle as it may be bent. Then unthread the machine and manually turn the flywheel through a stitch cycle and listen carefully, if you still hear a noise as the needle touches the rotary hook, you've knocked the timing out. Service man visit time.

Probably if you check the manual, it will say 50 weight thread, and you'll need to stick with that in the future.

Those big industrial sewing machines that they top sew jeans on are very different to a domestic SM, many make a chain stitch or fell the jeans seams and are very heavy duty.

I am trying to sew a boat canvas top with sunbrella canvas. my top stitch is beautiful but the bottom stitch is loose and messy. Is this just a tension adjustment and if so what should I be adjusting?


Try adjusting the top tension dial to tighten up the loose stitching on the underside. Generally if you have loose threads underneath, its the top tension and visa versa.

However, if you are using a thread heavier than normal sewing thread through the needle and bobbin (which you probably need for this canvas) then the machine may struggle. I've sewed vinyl seat covers and gave up with my domestic machine and purchased a second hand industrial Singer machine 20U to cope with this heavier weight textile. Generally for anything heavier than upholstery fabric a domestic machine may not be strong enough.
