Tension Problem

hi everyone... I have a Bernette 46. It was working fine until a month or so ago. Now the top stitch won't drag under the fabric. I can see the bottom stitch coming up just a bit. I've adjusted the tension to super tight, and super loose. It doesn't change the tension. I've re-threaded so many times I've lost count. I think that the thread is getting in between the cylinders/discs just fine. I've also replaced the top thread the bottom thread, tightened the bobbin, cleaned and oiled my machine, and replaced the needle again. The tension is staying the same. Any suggestions ? Do I need a new bobbin casing

Five Tips to Solving Thread Tension Problems

1. Use a brush to clean under the needle plate and in the bobbin case to remove any accumulated lint. Oil if necessary.

2. Replace the needle. Even new needles can be damaged. (I recommend always using a Topstitch needle for decorative stitching because of its sharp point and large eye)

3. Re-thread your machine.

4. Re-set the bobbin, making sure the bobbin is turning in the direction the manufacturer recommends. (Clockwise or counter-clockwise)

5. Change your thread in the top and bobbin so they are the same weight and composition. I like to use a 40wt cotton for this step. Make sure you have your thread spooled correctly. Cross-wound spools need to feed into your machine on your horizontal spool holder and parallel wound spools need to be mounted on your vertical spool holder with the thread unspooling from the back.

If these steps don't solve your tension problems, it's probably time for a tune-up at your local dealer

Thanks
