Assuming your hand wheel can turn and needle can move up & down. For a zig zag machine, it could be your timing belt broken/loose or your timing gear/upright gear has worn out. Suggest you send for service/repair.

I have a Bernina 770QE. The bobbin (black) is stuck in the bobbin casing (chrome). How do I get it to release?

Take the bobbin assembly loose and turn your hand crank and move it until the hook is at the top. Pull assembly apart and clean the assembly with qtip and sewing machine oil. It will likely be dirty that is causing parts to stick. If the bobbin spring feels weak it may be a good idea to replace it.

How to remove broken off needle from pfaff machine

Pfaff Machines are difficult to work on so I would only recommend you to take it to your repairman.
For the basics though you can remove the bobbin case assembly and see if you can see where the needle may have dropped and gotten caught on the bobbin case assembly. Replace the bobbin case assembly after you have tried to remove the piece. If you can pick up your machine and shake it slightly and hear the part moving around then you can feel sure it is on the bottom of the box that holds the machine. As long as it is in this location it won't pose a hazard for your machine. If you still feel there is a hazard then go to your local repairman.

The bobbin driver assembly is not moving. Is this controlled by a gear that can be repaired or tightened?

1. There are gears that drive the hook assembly. Many machines have plastic gears and can be broken or will dry out and break due to age. Yes, the gears can be replaced.
2. The bobbin driver assembly does not suppose to spin! Under the bobbin assembly is the hook (sharp object) that turns.
3. Test the machine to see if it will sew by placing the needle on the far left and then on the far right. Try both to see if it will sew. If it is sewing on one or the other you will need some adjusting from a qualified repairman. The needle just for your information is swinging too far to one side or the other. The other most likely possibility is the timing is off.

The wheel on the right side of the machine is sticking, and now it is stuck and won't move.

a. Rotate backwards a little. This should loosen it up some.
b. Remove the bobbin assembly and put it back together carefully.
The bobbin case on top loading has a part that must be moved toward the back to prevent the bobbin case from rotating. (It has two screws usually)
c. Before replacing the bobbin case put a drop of oil on the race. (race is a little area that looks like a race track)

How to replace bobbin assembly correctly on my singer merritt 4530 ? the threads been getting caught all around the bobbin assembly.

Yes, it should, and you might want to download your user's manual free at the Singer website, because replacing the bobbin case is pictured there.on page 41, along with instructions.

However, I can tell you that the feed dog plate with the two screws in is DESIGNED to be removed, and must be removed to get the bobbin case back in. It's important that you follow the instructions; the case must be inserted correctly so that it does NOT move, and make sure that it sits evenly in the bobbin basket (the thing that holds the bobbin case. While you are at it, you might want to also clean the basket, using q-tips with a drop of ONLY sewing machine oil on the cotton, making sure you also get under the lip before you put the bobbin case back in.

The part that holds the bobbin case down must have enough room for thread to move across the top of the bobbin case without getting jammed. Turn the hand wheel while you monitor the movement of the thread. If it gets jammed you will have to adjust the holder by loosening the bottom screw and move just a small amount. Also check your bobbin to make sure it is the right size. If it is too high it will jam the thread.

Loose top thread bernina 1008, tension problem but no solutions yet...

Are you sure you are getting the top thread between the tension discs? You should be able to tell the difference when you lower the pressed foot.

Bobbin case not working

does the hook assembly move when you rotate the handwheel? If "no" then the lower gears are shot.

When i sew the bobbinbinds up underneath plate and stops

What are you doing when this happens, embroidery or sewing? Also are you creating a nest, or does the bobbin not move freely?

Check to see that the bobbin is not over wound. The thread should not touch the sides of the bobbin case. This can happen if the bobbin adjustment, the white dial adjacent to the bobbin winder, has been turned and the bobbin winder kicks off too late.
