If your Bernina 830 or 930 no longer ziz zags, there could be a simple fix to a common problem where the changeover lever mechanism is jamming.
This is a very common cause of these models not zig zaging properly or not at all. There can be other causes of no zig zag but I see this a lot as the main cause.
It's simply just a matter of applying sewing machine oil to the correct place and exercising the changeover lever.
It's also an indication that your machine may need a service as it's likely other parts need cleaning and lubricating.
