Question about Singer Quantum 7322 De'cor Mechanical Sewing Machine
The top thread catches the bobbin thread, but has no tension, so the bobbin thread fills in the satin stitches, zigzags, etc. You can't even see the color for all the white bobbin thread. I've cleaned everything completely and retreaded countless times. I've tried adjusting the top tension up and down to no avail. I tried regular straight stitching and the top thread just lays on top, feeding out only because the feed dogs move the fabric. The threads are "caught" like they should be, but not with the right tension.

It sounds as though the design is stitching but the machine is skipping stitches. If this is the case, be sure you hoop the tear away in the hoop with your fabric.Make sure the fabric is taut. Use a new needle and a good quality thread.If this doesn't solve your problem, try the design on a different type of fabric.

I just fixed this on my pfaff 230-the problem is the needle position dial-the middle dial with the chrome lever on the right-has froze up .
remove the dial-it doesn't come off by the screwhead in the middle of the dial ,the screw you need to loosen is the one under the wider end of the part of the dial you hold-you will need a glasses screwdriver.
once it is off ,heat the exposed shaft with a heat gun while turning the shaft back and forth with pauses for dripping 3 in 1 oil on the shaft so the heat melts the hardened grease and draws the 3 in1 in to flush out the old grease and lube the shaft.
eventually you will be able to turn the shaft easily-then when it cools off replace the plastic dial.make sure your upper dial is on "0" there is a cam on it that will push down the other end of the chrome lever.
This will work-there is no plastic in the shaft and arm assembly to melt and you don't have to dissasemble from the top-that sucks.

Make sure to thread the machine with the presser foot up to insure the thread is seated into the tension control.
Always free-motion with the presser foot down.
Try a lower setting on the tension.

You don't have much info here to go on. I take it that it embroiders fine otherwise, ie on the built in designs. Is it a Janome card? Does it do it on a particular card / design? Have you changed the bobbin thread that you use? Check the top tension - even though it is 'automatic', it does require adjustment at times. Have you changed / using stabiliser that you use? Is the bobbin correctly threaded?
Check these things
