How do you adjust the tension on a Bernina 180
There are two tension adjustments, which should be done with a proper set of weight gauges - top and bottom thread tension should be carefully balanced to get the best stitch formation. It is best that you assume the top tension is correct and adjust the bobbin tension to match. Load the bobbin with thread of one colour and put a spool of the same thread but a different colour on the top. Thread-up the machine, load the bobbin and sew-off a satin-stitch on max width zig-zag. In this configuration, there should be a very small 'bead' of the top thread showing along each side of the satin-stitch on the underside of the material. If there's excessive top showing, the bobbin tension is too high and if none, the bobbin tension is too low. To adjust the tension, remove the bobbin case and you will see a spring around the edge with two screws through it. One of the screws holds the spring in place and the other adjusts the tension - this is furthest from the edge of the spring and is in a small 'cup' in the spring itself. To reduce tension, turn the screw VERY SLIGHTLY anticlockwise and to increase it turn it clockwise. Make very slight adjustments and re-check sewing-off the satin-stitch every time until you get the required thin line of top showing down each side of the stitch on the underside. Ideally this should be done with Mettler Metrosene thread, but as we're just balancing against the top tension, it shouldn't matter too much provided you use a good thread top and bottom.

Why won't Bernina Artista 630 turn on?
If the machine won't power up its most likely a problem with the power board inside of the machine. I have replaced a bunch of bad power boards on the 600 and 400 series Berninas over the years. The 600 and 400 series machines use the same board. I service and sell lightly used Berninas on eBay under the user name bushvideo.

Can you tell me what the bobbin image on the
Hi, most likely your bobbin sensor is being blocked by something. Common causes are a dirty sensor. Q-tip on the eye of the sensor inside the bobbin door. Or there is fuzz blocking it. Next take out the bobbincase and the bobbin. Look in the bobbincase and you will see a round spring. This spring acts like a brake for the bobbin. Sometimes these springs will get moved and out of position blocking the little space that the bobbin sensor reads through. Reposition the spring so you can see through it and the bobbincase.
That should do it.
