I found my much looked for sewing machine on a second hand site. A Bernina 830 with lots of feet, extension table etc. Obviously decades old but advertised as fully working. I bought it and drove an hour to collect it. They were happy for me to try it and unfortunately the stitches didn’t work - the thread picked up the bobbin thread at the start but they didn’t make stitches. It also made a higher pitched noise as well as the usual running noise, The thread came out of the needle all the time (we tried changing the needle and adjusting the tension). The seller said she hadn’t used it in about three years and couldn’t remember when it was last serviced. The sale was cancelled.
So, it’s a good price for what’s included and I’m wondering if it’s worth offering a reduced amount and getting it serviced and risking that it’s a relatively minor issue? Has anyone had a similar issue or know how much it is to service an old Bernina (London)? I’m also thinking there may not be parts readily available for this machine?
