Bernina 830

Since the top tension is normally set on (with the foot down) the lever provides for movement of a small pin in the disc assembly when the hold down is lifted. I think that was part of my problem in that the pin would not come out and engage the tension discs all the time each time I lowered the foot. Intermittent problems are the worst. I tiny bit of thin lube and working the pin in and out a few times seemed to help

Glad things are working for you now and thanks for sharing your problem-solving! I sew on a 30+ year Bernina sometimes and that still does a better job than the newer machines we've got on hand. ( Use a lot of donated machines at church)
