Question about Bernina Sewing Machines

1 Answer

My Bernina 1031 is making a slight knocking noise and the thread is balling up on the understitch.

I know it is threaded the right way, but not sure of the bobbin thread. If it has to be in one direction or the other.(?) It was serviced and not used but a few times since. Was running fine one day...not the next.

    Is still doing the same thing.

  • then it's time for the machine to be checked to see if the machine needs some type of adjustment or if it has a timing problem

  • check to see if the top thread is coming off the thread take up lever that will also cause the machine to have problems.

SOURCE: Needle won't pick up bobbin thread - HELP!!!

I recently fixed my wife maching with the same problem. I found that the screw had come loose that holds the linkage together that rotates the bobbin holder. I was fortunate enough to notice the screw while looking at the machine. To replace it requires taking both the front and back covers off of the frame since the bobbin holder linkage is in the rear behind the needle area. Be careful to insure that the plastic toothed "rail" that runs the bobbin holder is positioned properly or it may break off a tooth. Once I replaced the screw and put the machine back together, it picked up the thread with no problem. Hope this helps.

It could be that there is a loose piece of thread, or some fluff which is obstructing the tension gauge. Try blowing around the theading area (or even run the hoover pipe near it to see if you can **** it out). I cleared mine by folding a piece of non fluffy material and rubbing gently between the tension dial and machine.

Good luck

SOURCE: The needle thread will not pick up the bobbin thread

It looks right but its not. Try looking on the internet for threading instructions. The bobbin winds in two directions, I have never saw a Bernina but I have 2 new machines and the thread goes in and then threads back to the left. Its hard to describe. But if the bobbin isn't right it will not pick up the thread. Write to Bernina for instructions. There are websites that have the directions for free.

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: Not catching stitches / bobbin correctly

Your timing has been messed up by breaking the needle.  When the needle hit the bobbin race, it shoved the needle bar up and now the needle is not in the correct position to catch the bobbin thread when the race rotates.  The needle has a little dip in the back, called the scarf.  When you take the neddle plate off and watch it move, you should see the little hook pass through the scarf.  That's how it makes the locking stitch and picks up the bobbin thread.  Unfortunately, you will need to take this in to a dealer or service place to have them adjust the needle bar height.  It's not a complicated task so see if they can check it while you wait.  It may be more difficult to fix, like retiming the machine.  But it doesn't sound like you've done any major damage to the mechanism.

Thread balls up under plate I think it is the shuttle tension, but I havent used it in years,it worked fine then. I did oil the area under the shuttle to se if that worked. It still balls up Bernini...

We have about 100 of these machines in the schools around out city. so I know a bit about the 1008/ 1020 Bernina machines.
Sometimes the tension discs get sticky if you have not used the machine in some time.
raise the presser foot then check to see if the disc in the center of the top tension is sort of loose as you try to move it slightly/
-be sure the top thread is securly in the tension when you thread the machine. after putting hte thread through the top tension, pull on it slightly while the presser foot is in the top tension and it should be loose.
now lower the presser foot and now pull on the thread it should now have some resistance.

Now check the bottom tension on the bobbin case and be sure the bobbin rotates easily when you put in the bobbin whilst putting the thread under the bobbin case tension spring. The tension at this point shold be fairly easy to pull from the bobbin case.

if this still does not help,
remove the shuttle/hook (see instrutions at bact of instruction book. check to see if there are any nicks in the shuttle. if there is then use emery cloth of some fine crocus cloth to refinish and make the pointed part of the shuttle very smooth.
That should do it, if not contact me at

Loose, loopy, understitching.

Generally caused by lack of tension on the upper thread. Thread machine normally and pull the needle thread sideways from the needle with the presser foot up. It should pull smoothly. Lower the presser foot and it should become hard to pull and the needle will bend. If this doesn't happen, the upper thread is not in the tension assembly and you should rethread properly. Also, make sure thread is in the take up lever that moves up and down on the front of the machine while sewing.

Old bernina 830 stitching problem: tight

Sounds like you need to adjust the tension. Probably a good idea to oil this older machine before you adjust. Also look for and clean out any lint or debris in bobbin case and around foot area.

Machine problem


There are so many reasons due to which the thread is not picking up from the bobbin like:

The upper thread could be tangled. Remove the thread completely from the machine. The correct size spool cap should be used for the size of the thread spool. Re-thread the machine. Remove the bobbin and make sure the bobbin is threaded properly in the shuttle race. Remove any loose threads or lint in the shuttle race.

You could be holding the needle thread too tight. Hold the thread lightly to keep the end from going down into the shuttle.
The needle could be threaded incorrectly. Thread the needle eye from the front to the back.
The needle could be bent or improperly inserted. Install a new needle with the flat side of the needle facing the back.

Do rate the solution as FixYa and revert for further assistance.

Threading the bobbin

It could also be the tension of the thread while you are threading the needle through the upper system. Keep a slight tension on that thread while doing it. Otherwise, make sure that the bobbin thread is 'coming' from the right position on the spindle.
