My Bernette 65 sewing machine isn't pulling my main thread through. Bobbin tread is being pulled fine. What could the problem be?

It sounds like it! Take it in for service.

thread the machine correctly( follow the operators manual)
wind the bobbin properly and when placing the bobbin in the bobbin carrier pull the thread down the small slot and under the spring plate
thread for the needle always comes in from the left (The side of the groove in the needle ) and out the cut away side
pull a long piece of thread for the needle out and hold it while you turn the machine over
after 1 or 2 revolutions the needle thread will bring up the bobbin thread and you then pull both threads out a bit
if you don't have a user/operators manual there are 2 options
one is to go google and type in --user manual for bernina bernette model 65 sewing machine and down load the pdf version
the other option is to visit manchester shops ( cloth and fabric shops ) and talk with the sales people as may of these places have a sewing circle of people who will be only to willing to help you.

The bobbin spindle needs to be moved to the left in the slot to disengage the winding mechanism. (It may be easier to do this with the bobbin on the spindle. The bobbin and spindle should be moved to the right after putting the bobbin on for winding.)

The directions and pictures for winding the bobbin are on page 30-31 of the manual. The manual is available from Bernina on their support page for the out-of-print Bernette machine manuals: .http://www.bernina.com/en-US/Support-US/Out-of-Print-Manuals/bernette-manuals/Bernette-Sewing-Machines .

I hope this helps.

The bobbin will move only when the thread is being pulled. The problem with your machine is that the timing has missed aligned. It will need service. 99% of all sewing machine misalign due to continued use.

Try going to this link and download the manual for either the Bernette 410 or 715 and look at the directions for threading and inserting the bobbin:

Bernina may not have a manual for your particular model, but these models may be close enough that you can still use the directions for your machine.

Try changing the needle

Try rethreading the machine top and bobbin

Make sure the bobbin is turned the correct way In the bobbin case

It's possible that the machine needs to be checked for a timing problem

try a new needle--one that is for the fabric being sewed
then try to adjust the top thread tension again, if the stitches remain loose and the tension won't adjust then the tension knob needs to be checked to see if there is something wrong with it.
also check to make sure the bobbin is inserted correctly into the bobbin case, if the bobbin is not turned the right way in the bobbin case the sewing machine will not stitch correctly.

Grasp the threads and hold them down when you start your seam. If it still happens make sure your thread is seated into your upper tension mechanisms. If that still isn't solving your problem... CLEAN between the tension discs with some sturdy fabric folded in half. (wax build up from threads can cause issues)

Good luck

If the bobbin thread is coming up to the top, then the thread is not under tension correctly. I think that this is a top loading bobbin so the bobbin will go into the bobbin holder, then you pull the thread back and press it into a tension device - should hear it click into tension. Now pull the thread back towards you and it should not come out of the tension. The bobbin should turn anticlockwise as the thread is pulled from it.

These bobbin holders usually will have a small adjustment dial on them and it should have the standard setting marked in red. It is very unusual that you would need to change this but check that it hasn't been messed with perhaps. If you have the machine manual check where they say the dial should be set. More likely that the thread is just not into tension fully or at all.

The manual may give you other troubleshooting tips too.

A good resouce is www.sewing.about.com for general machine tips, cleaning and threading issues.

Hope this helps.

Have you checked the upper tension? It can do that.
