I would take some fabric to sew and try it out. You are paying for it to be fixed....you can check and make sure it is.

Considering the Bernina 830 is a very sensitive machine (I have a 830LE) I would ask the service tech to set it up & put it thru all stages while you watch. Say you want to make sure you are using the machine right. Ask questions as you go ...like threading, bobbin, embroidery, BSR, different stitches, etc. Try different threads & needles. Ask him to show you how to clean it & oil it. Take fabric along to sew on & make sure you have some big enough to fit the large hoop for embroidery a few times. Also take ALL your bobbins along & have them checked for worn paint. If they are worn this can cause the machine to not function right. Bernina is supposed to replace them for free, if the paint wore off, as it was an issue a while back. One more thing the 830 requires it be level on your sewing table or this could throw the timing off.

That machine is so complicated. I would go as far as to make an appointment with the tech, so he can sit down with you while you try it out.

YES. Absolutely. I'm sure you have the right to make sure it is running correctly.

I agree with all of the above comments. I take my 830 to the same tech....same dealer all the time. Every time I take fabric to do a test and always ask if my updates are up to date. Each time I learn something useful.

I would definitely try it out there. Read my story about my 830 on "Bernina 830 fixed!!!". Please copy that into advanced search. I am unable to copy thread title and paste into the reply box. Can anyone tell me how to do that? Thanks.

Oh yes, I agree with thimblebug as you want to make sure it is truly fixed!!
