My sewing machine tension is suddenly messed up and nothing seems to fix it
Hi, I was sewing when my machine suddenly made this little thump noise (it does that quite often so i didn't think much of it) but ever since my stitches come out like this (pictures 1-frontside, 2-backside,
the numbers represent tension on the tension wheel from 0-low to 9-high tension )
Also while im sewing on fabric when the needle goes thru the fabric it makes a teeny tiny thump noise but when I run the needle without fabric then it sounds normally.
I've tried adjusting the tension (pictures), changing the needle, changing the presser foot, rethreading the bobbin thread a couple of times, changing the upper and bobbin thread to a completely different thread, changing the fabric, cleaning EVERYWHERE out of dust, changing the stitch length and type, tightening that little screw on the bobbin and NOTHING worked and my stitches still come out messed up.
I've had this sewing machine for not even a year long and I don't sew super often. It's Łucznik Polonia 2018 (the red one).
Pls help I just started a cool project and I was so excited about it but now I'm stuck ☹️
