The bobbin seems to be stuck and will not move...all it's doing is 'eating' the thread...what do i do? Thanks

It sounds like you haven't threaded the bobbin thread correctly. Remove bobbin, bobbin case. If it is stuck, do Not, do not force the assembly, rather look for tangled threads and calmly snip the thread and remove. Once the tangle is gone, remove bobbin and bobbin case. Rethread it carefully. And contact me if you continue to experience difficulty. Ayou may need step by step directions.

1. You need to remove the bobbin case and adjust the tension. The tension should allow the thread to move with a slight tension. Clean the area with a qtip. The bobbin case sits in a an area that is called the race. The race needs one drop of oil. Replace everything.
2. Replace the needle. Make sure it is in the right direction. Thread the top while the foot is up. If the thread gets stuck while threading there is a problem. The thread should move easily while the foot is up. After you thread the machine except the needle you can put the foot down. Now pull on the thread. It should give you a slight amount of tension. Usually four is a good number. If the tension is too tight you can adjust as needed. Now, thread the needle. Hold the thread under the foot while you turn the hand wheel. The bobbin thread should come up.
3. Give your machine a try with a slow speed.

computerized so could be anything

tension or sewing action parts needs a service

I had this problem with my 7570. I kept trying to wiggle the hand wheel. Took everything apart I could to get at it. Finally after many try's it moved and I was able to use a tweezers to get the tread out. A friend suggested applying a drop of oil to the bobbin case and letting it sit. She said it would desolve the thread some so you could move it.

a bit difficult unless you are a machine mechanic or have a detailed workshop manual beside you
I would not waste time DIY and would take it to a reputable sewing machine repair shop

First... make sure you are threading it correctly. It MUST be threaded with the foot up.

Do a test seam. Make sure you put the presser foot DOWN when you sew.

Make sure you grasp and hold the bobbin and top threads as you begin the seam. (this is good practice for any seamstress on any machine.

If you still get loops, tighten top tension.

Also check the bobbin case for burrs. drag a finger nail along edges to feel for it catching. If you find one take a small bit of extra fine sand paper and file it off.

Good luck

try changing needles
clean under the needle plate & in the bobbin area for loose thread or lint
make sure the bobbin is inserted into the bobbin case correctly--if the
machine won't pick the thread up from the bobbin correctly take the bobbin
out of the case & turn it around & try it that way.

the bobbin case does not move, just the bobbin.. if the machine is still under warrenty, I would take it back & get another sewing machine,, and probably not from them

This happened to me. I took apart the bobbin and there were no threads stuck. It moved freely, but the hand wheel was still stuck. So I checked the belt between the handwheel and the motor. I tugged on it (while the machine is off) and tugged on the belt to turn the handwheel. It took a couple tuggs to make the handwheel move, but once it started moving, it seemed to unfreeze. And I was back to normal. I can’t tell you what happened, but it’s fine now.
