Question about Bernina Activa 130
SOURCE: long stitch!!
Hi teza...I assume that you have decreased your stitch length selector resulting in no change, indicating that the internal stitch length mechanism is either insufficiently lubricated, or truly broken If not broken, you can work the mechanism free by removing your needle, selecting the maximum stitch length and any non-overlock stich pattern, ie. straight or zigzag, fully depress your foot pedal so it runs at maximum speed, and methodically press and release the Reverse button/lever. After a minute of this, hand crank your machine while observing the feed dogs, and changing your stitch length. If your stich length is set to 0, your should observe your feed dogs moving vertically up and down with no back/forward motion, however, increasing as you lengthen your stitch length. Repeat the previous high speed work out until you notice full strokes of your feed dog...good luck my friend

If your feeddogs look like they are working properly it could be this...I have seen and corrected a few problems like this in the past. What can happen is your needlebar is stuck in the Basting position. Basting is when even though the machine is turning properly the needlebar will only go down every few revolutions. There is a small pin in the needlebar that disengages when Basting stitch is selected (by an electro-magnet). Usually these will stick from hardly ever or not using it. Old oil gummed up usually but can happen in a drop. The pin will not go back in. Possibly (probably also) the needle bar got turned ever so slightly knocking the hole for the pin slightly off so it can't go back in. In which case the needlebar has to be turned to the correct alignment. This should only be fixed by a trained tech. Everyone... use the basting feature occasionally. We have a saying about those. "Use it or lose it".

Because you say all was working for a while before this latest event, it will be the supressor that has failed, they are generally in the foot control (some machines have them in the main body near the power inlet) and it needs to be removed, it only stops interference to Radio & TV and is not necessary for correct function...............your nose will tell you if it is in foot pedal or inside the machine..
Unplug from mains, undo cover/s and find the electronic looking item which is cracked, burnt & probably oozing brown goo and smelling like burned plastic only worse.... Simply remove this from the circuit, clean the region with some denatured spirit, methanol or similar, wait until completely dry and re-assemble....this should fix the problem of the machine "running on" by itself....as to whether you have done a good job of the initial electrical repair, only you will know that.
By the way, how's the dog ? Guess the machine was not plugged in at the time !!

Basically it is a matter of a stuck part. Flip open the top by prying up on the front or ends of the lid. You already noticed the hinges on the back. When you get it open, exercise the right hand lever on top (marked ZZ at bottom and 1-20 at top. If you look just to the right of this lever against the back wall you will see that it moves a little part back and forth into triangle shaped grooves. The part is not going completely into the grooves so drop some oil in there and exercise it a few more times, using your fingers if necessary to make the part move into the triangle grooves at the front and back. After a while it will loosen up where it should operate by itself smoothly . Hope this helps.

If its not the footcontrol (which it probably is) it is most likely the circuitboard acting up. Needs a tech.
