I have threaded my Bernette 90E and after I put the bobbin in it only works backwards. This is the first time ever its doing this. How can I fix it?

The manual for the Bernina Bernette 65 are available from the manufacturer here: https://www.bernina.com/getdoc/6d2754b8-af09-4edb-a6a6-7a4c57965b8d/bernette-55-65-80e-90e . The three dials, from left to right, are thread tension, stitch length, and stitch width (page 9, page 12 of the PDF). See page 24 (page 42 of th ePDF for the pictures of the appearance of the correct tension versus the incorrect top thread tension. For best tension testing, use different color top and bobbin threads. Do use the same thread type and needle appropriate for your fabric and use scrap from that same fabric. In general, if the top thread is visible on the under side of the stitched fabric, increase the tension (turn the dial to a higher number). If the bobbin thread is visible on the top of the fabric, reduce the tension (lower number). Make sure that the machine is properly threaded. (Make sure that the presser foot was up during threading and is raised when you adjust the tension dial.) Start with the tension at 4 and change the tension in small steps. (Do not turn the dial more by 0.5 before stitching a line to test the tension again. You want to avoid over-correcting.) When the tension is correct, the top and bobbin threads will meet between the two layers of fabric for a normal seam.

I hope this helps.

(These steps are the same for any sewing machine with user tension adjustments.)

Do you have the bobbin in correctly? Clockwise or counterclockwise...
Is the needle in correctly? It could be backwards.
Rethread the bobbin if the thread is not wound on properly...too fast makes the thread too tight, too slow and it can wrap onto the bobbin in a haphazard way.
Check to be sure have the correct needle for your machine...matches stitch etc..
If your machine is electronic...turn it off so it goes back to any default settings.
seems like a lot, but one little thing...

Do NOT try to turn the handwheel backwards. This will frequently cause the machine to malfunction requiring professional service to repair.

Consult your owner's manual in the Troubleshooting Section for solutions to your problem. Check to make sure the bobbin winder is still not activated.

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 .

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.

1. Your bobbn is in backwards
2 your needle is in wrong (backwards or too low)
3you are using the wrong bobbin
4 your machine timing is off

hi! there,
open needle plate if the shuttle race and the bobbins has been pull out that making noise,or accumulation of thread under bobbins, if nothing there, run machine and check if shuttle race and bobbins are moving,also with the needle if not,there are opening at the bottom of machine try to open if some gears are broken,or belt is slip.
if broken gears there a lot of parts before you can pull out gear, beside the timing order you cannot put back.this should be done by technician expert
in sewing machine.take this to service center.
cheers have a nice day just rate me.

Possibly you have the bobbin back in upside down and its turning the wrong way. Happens all the time. If you mean it will not pick up the bottom thread then maybe the needle is in backwards or the machine is out of time. I doubt you will have to replace a part but if it does or you need to have the timing adjusted you will have to maybe look at the Yellow Pages or here online and find the nearest sewing machine repair or dealership and have them look at it.
Good luck

Our Bernette E90 timing was off due to a jam (design flaw I think)...Instructions on how we fixed it.

1. To correct timing, tip over machine and unscrew inspection plate.

2. Find the gear and unscrew the 2 grub screws so the gear is free from the shaft

3. Turn the main sewing machine handle to manually get the hook (pointed piece) of the housing (see arrow) to be directly behind the needle

4. Hold it the tightly, and turn the handle again, the needle should be able to go up and down while holding the hook in position.

5. When the needle is at it lowest and starting to move back up and the hook is directly behind tip the machine over and tighten the 2 grub screws on the gear underneath.

6. Replace inspection cover and you’re done
