Repairing bobbin thread uptake

make sure the presser foot is at it's hightest position, then thread the top
of the machine
change the needle
make sure the bobbin is not over full
that it is turned the right way in the bobbin case
if none of these suggestions work,,it is also possible that the machne is
out of time & needs to be checked at a repair shop

here's a link for a manual

check the needle to see if it's damaged
have a thread tail for the top thread & bobbin thread of 3-4 inches
try this & see if it helps you
make sure there's a 3-4 inch bobbin thread then, hold the top thread tail (3-4 inches) with your fingers away from the needle & then use the handwheel on the right side of the machine & lower the needle down into the bobbin area & see if it pick up the bobbin thread that way
make sure there's no lint or loose threads in bobbin area

If you threaded the machine with the presser foot up and the is bobbin inserted so the bobbin thread is feeding from the bobbin spool in the correct direction and through the guides as indicated in the manual, then there is a possibility that the timing needs to be adjusted by an authorized Brother tech.

Chances are you will need to retime it if you have checked everything else, if you email me with your make and model I can attach instructions

This is sometimes caused by the upper thread not threaded correctly. You need to thread it first with the pressure foot in the up position. You need to "floss" the thread into the clear plastic guide as this is where the tension is. The tension should be set to E for embroidering. Also make sure you get the bobbin thread in the slot on the bobbin case. Also, lower your pressure foot before you begin embroidering. Hope this helps!

Be sure the bobbin thread is coming off from the left. There is a picture on my Futura bed that shows the correct way to insert the bobbin. If the thread is comming off from the right you will have the problem you described.

Good luck,

There are some different bobbin cases for different machines but the one you have is a pretty common one with a finger sticking out on top. If you examine the bobbin case you will see a slot on the side of it and there is another piece of metal screwed onto it. This is the tension they are describing.
To thread it properly, turn the bobbincase upside down and insert the bobbin in the case so you can see it. Place your thumb on top of the bobbin and pull the thread through the slot on the side of the case and under the piece of metal(the lower tension) which I described to you earlier.. When you have done that, remove your thumb from the bobbin and pull on the thread. It should have some tension on it.
Next,placing a thumb or finger on the bobbin to keep it from falling out, turn the bobbin case over.
Keeping the finger sticking up lift the lever on the
front of the case and insert the bobbin and bobbin case onto the spindle inside the hook assembly(The part that is in the bottom of the machine that turns when the hand wheel is turned.) Don't worry about the thread that is sticking out.
Holding the upper thread under the presser foot ,turn the handwheel towards you until the top thread pulls the lower thread to the top. Pull the thread to the left of the machine, insert your fabric, lower the presser foot and begin sewing
One more thing , The finger sticking up on the bobbin case will go into a slot on the ring holding the hook inside the machine.
Hope this solves your problem.
Be sure you thread the upper part properly. It should go through the tension, then the take up lever and then the needle. Tension should be set at around 5

Sounds like hook/needle timing is off. Check it by doing the following with the power off:
remove bobbin, bobbin case, and needle plate.
push needle all the way to the left.
Turn handwheel toward you watching the needle and bobbin housing hook. The point of the hook should line up right above the eye of the needle.

If not timing, clean bobbin area removing lint and thread.

Check bobbin tension, should get slight resistance when pulling thread.

Make sure using only Husqvarna Viking bobbins.
Make sure the bobbin is unwinding in the correct direction.

Remove fabric. Pull extra long bobbin thread (about 3 inches). Hold upper thread tail in left hand, turn handwheel toward you for 1 revolution. Is the bobbin thread caught by the top thread and pulled through the opening of the needle plate?

If you are still unable to sew, take to an authorized Husqvarna Viking dealer for service or have them send to Husqvarna Viking (SVP) Technical Service Dept for repair. A list of dealers close to you can be found at the Husqvarna Viking website - http://www.husqvarnaviking.com/us

Good luck.

Have you checked to see if the Thread has slipped out of the Tension guides? Here are my quick steps to getting back to happy sewing:

1. Remove bobbin and blow out the dust from in and around the bobbin case, when replacing bobbin... make sure it the thread is traveling the right direction in the bobbin case. (this one never hurts to try, a backwards bobbin causes lots of probelms)
2. Re-thread the machine (the thread in my Janome sometimes comes out of the thread uptake lever causing the problem you described, could mean your threading path might need to be cleaned)
3. New needle (the tiniest bent needle can cause hair pulling issues.)
