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.

12 wt thread


12 wt thread generally will not work well in the bobbin...


"Aurifil 12wt Thread
Aurifil 12 wt thread is ideal for hand quilting, big stitch hand quilting and machine quilting. 12 weight thread creates a more defined and often primitive look. It's great for designs that use a longer stitch length if using a machine. When machine quilting with 12 wt thread, use 40 wt in the bobbin, increase your stitch length, lower your tension, use Topstitch size 90 needles and stitch slowly."

is the fabric & thread & needle compatable with each other?
did you use every thread guide when threading the machine?

is the bobbin warped?

My bernina activa 130 wont sew


Fit a new needle, clean and oil the hook race, whether-or-not your manual says it doesn't need it and check that you have some tension on the thread coming out of the bobbin case and top tension unit. Are you threading the top thread with the foot up or down ? You should always thread the machine with the foot up to ensure the thread goes through the tension unit properly.

Bernina 135 bobbin winds unevenly


If you are finding that the bobbin is winding with more thread towards one edge of the bobbin than the other, the bobbin winder motor needs to be adjusted so that the angle of the winder shaft is properly aligned with the tension disc next to the head cover. Unfortunately, unlike many of the other models, you have to remove the covers on the Activa range to get at the adjuster. There is a spring-tensioned screw just to the left of the bobbin winder motor that adjusts the angle of the motor and therefore how it loads the bobbin. If the winder is loading the bobbin with most of the thread towards the bottom edge, the screw should be turned clockwise and if most towards the top, it should be turned anticlockise. Make adjustments until the thread is winding evenly or, at least, towards the centre of the bobbin.

If you are finding that your bobbin is being loaded somewhat randomly, make sure you are using the vertical spool holder to hold the spool and that you've got a foam pad under the thread spool. Route the thread through the thread guide before winding around the tension disc in the correct direction (see the arrow on the case) and ensure that the spool and thread do not vibrate unduly when the bobbin is being wound. If you let the spool vibrate whilst the bobbin is loading, it may result in varying tension on the thread and uneven winding onto the bobbin.

Issue with Bernina Activa 130: The stitches seem really loose and raised/bumpy. Not sure how else to describe.


Check that you have got the thread correctly routed on the bobbin case and that there is noticeable 'drag' on the thread when you pull the thread out of the bobbin, in its case. If there's little or no drag, it is likely that the bobbin tension needs increasing. I'm assuming you've set the top tension to thered line. A good check is to load two colours of the same thread type top-and-bottom - when sewing on wide zig-zag, the top thread colour should be the only one seen on the top of the material and the bottom colour should be mostly seen on the bottom ... it's OK to have just a spot of the top colour showing on the underside on wide zig-zag/satin stitch.

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.
