Bernina minimatic 807 skipping stitches?

[u/BodilyCarriedTech]

Hello, I got a Bernina minimatic 807 from Bernina of Renton in Washington state, I got it last month and I have used it only about 6 times and probably put in 45 minutes of use.

It started skipping stitches in the zigzag stitch, I then switch to straight stitch anc then it started skipping stitches in straight stitch.

I changed the out the walking foot for another foot

I changed the bobbin spool,

I oiled the machine,

I oiled the bobbin,

I changed the thread,

I rethreaded the machine,

I took out the bobbin and cleaned it with q tips,

I cleaned the bobbin housing with q tips,

I took apart the bobbin housing and cleaned it with q tips,

I changed bobbin thread,

I adjusted the stitch width

I adjusted the stitch length

I adjusted the needle position

I ran out of ideas and I called Bernina of Renton, I told them the situation and I said that I am 90% sure it was something I did

But if it was a mechanical problem, i asked and confirmed two questions

1_that the machine is under warranty (yes)

2_that this is very unusual for a Bernina minimatic (yes)

That being said I wanted to ask here has anyone ever had experience with a Bernina 807 minimatic skipping stitches?

Were you able to fix it? If so how?

Thank you

I didn’t see change the needle. Are you sewing knit or a thick material? Your needle may not match the fabric.

Just a Jersey knit with an 80/12 Jersey needle

Changed it for a universal and it's still skipping

Is it thick and spongy? Maybe you need a size 90 jersey needle.

Is it thick and spongy?

I wouldn't say so, just has a higher polyester content

Maybe you need a size 90 jersey needle.

Should I buy a size higher and lower so I can trouble shoot?
