Hi there,
my machine just started making a knocking sound as i sew and now makes big loops on the backside of the material. is there something i can adjust myself?
thanks
thanks. i ended up talking to a local repair person over the phone, and figured out that the black plastic bobbin case had chipped slightly at the spring, causing it to wobble. so i ordered a new one, and hopefully this will solve the problem.thanks.

Are you using old thread? Is the needle threaded correctly, is the thread the same in the bobbin as the top. Are the thread and needle the correct size for the material? Is the stitch length and tension correct for the material? :-)
Maybe it just needs new carbon brushes. My Bernina 830 Record resembles the Pfaff very closely. I had issues with the motor stuttering. Changed the carbon brushes and it runs like a top!
If you have cleaned & lubricated the machine as indicated in your manual and the problem continues, the machine needs to go into the shop for professional service.

Sounds like the hook timing is off. You don't need a new hook but you may need a new position finger. If you are unfamiliar with working on sewing machines then it needs to go to the shop. This is a great machine and is worth keeping up. Pfaff doesn't make the all metal hook anymore which is a shame.
I don't have the same brand as yours, but on my machine there is a little screw on the bobbin case that you tighten to increase the bobbin tension. If you've got one, turn it 1/8 to 1/4 turn at a time.
Try installing a brand new needle. A bent/dull needle will frequently not pick up the bobbin thread.
If a new needle doesn't help, then most likely the machine has been knocked out of time (the needle and hook are out of sync). You can search for sewing machine timing to see if you want to try to fix it yourself or take it for service. Timing is usually affected when a needle hits something hard (like a pin, the needleplate or a hard seam of fabric) and is deflected
