Question about Bernina Activa 130

1 Answer

I have a Bernina Activa 135. It will sew for awhile just great and then it starts to make a crunching sound and the bobbin thread bunches up on the underside. It will then go back to sewing just fine and then......it happens again. It even does it on the striaght stitch. I am also looking for a sewing machine repair place here in Northern New Jersey as we have just relocated here. Thanks

That sounds like the bobbin is not put in properly. check your manual.

Bernina activa 130 tension loose after needle breaking into bobbin area


Is it the bobbin tension that is very loose? Try tightening it. Also check that the bobbin has been installed in the bobbin case, turning the correct direction and that the bobbin tension is threaded properly.

Bobbin Tension How and Why Tension is Adjusted

Understanding Bobbin Tension

Understanding Thread Tension Threads

If it is the upper tension that is loose and creating "thread nests" under the fabric, the machine is either misthreaded or possibly the thread is not seated completely in the tension disk.

Remove the upper thread from the machine.
ALWAYS RAISE the presser foot and rethread the upper thread from the beginning--verify the thread path is correct.
Set the upper tension to the midway point between high & low number (the factory standard--although it may need tweaking later for your particular machine).

Retest your machine. Hopefully, the issue has been resolved. If not, it may need service.

I have a Bernina Activa 130. I tried to sew over some leather, started fine, then the needle got stuck and I stopped right away. Now, the bottom threads keeps bunching. I have re-threaded the machine, new...


You need a fatter needle. The skinny needle will not open the leather enough for a smooth flow of thread and that's why the bobbin is bunching up when the top thread is sticking. Make it easier on your machine by using an appropriate size needle while sewing leather.

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 bottom thread will bunch up occasionally, and stop the machine with thread hooked somewhere--probably around the bobbin.


Hmmm, does the thread bunch up under the fabric or in the bobbin?
Check both your tensions and if that doesn't work it could be that your machine is slightly off time and needs to be adjusted.

I have a Bernina 130, the thread from the bobbin is coming out with huge loops, the top thread looks great, but turn over the fabric and you have a mess. Any advice is welcome.


Usually if your bobbin thread is loopy it's because the TOP thread is not threaded right. Try threading it again with the presser foot UP and make sure to get the thread between the upper tension discs. It's just the opposite of what you would think.....if the bobbin thread is loopy, the top thread is threaded wrong, if the top thread is loopy, the bobbin is threaded wrong. Good luck!

Buzzing Bernina Activa 135, possible bad service?


First of all, the question is: does that machine buzz when it's turned on but without you stepping on the foot control? If so, the likely cause is the power supply board. It is not defective as such, but some boards (whether new or after some period of ownership) do have a buzz, and without question some boards are noiser than others. If that buzz bothers you, the only solution would be to have it replaced with another new or rebuilt one (which would have to be done through a Bernina dealer).

Second is the issue of the bobbin area needing to be oiled after it's been serviced. Assuming when you say it was serviced that it means you had the machine tuned-up, then the dealer THEMSELVES should have oiled this area when they did that service. The bobbin area does need to be oiled on a regular basis (once every 6-8 bobbins' worth of thread usage is a pretty good guide). It would be my opinion that the dealer you took the machine to is indeed feeding you a line (about the bobbin oiling right after service), and I personally would be trying another dealer should you need further service.

Bernina Activa 135


either the bobbin thread is not in the lower tension or the lower tension is too loose or the top(upper) tension is too tight.
