Brother cs-6000 will not sew, the top thread go through and tangles on back, and the bobbin thread is a straight line and can be easily pulled out, please help, trying to make kids school clothes

bird nesting indicates that the needle thread tension is not tight enough
pull the thread out as if threading the needle and the tension is close when there is resistance to pulling the thread

The motor locked up because the thread is tangled.
Solution:
Remove the tangled thread before continuing the operation.
Clean the bobbin case to remove the tangled thread.
After cleaning the bobbin case, insert the bobbin case properly.
If the needle is bent or broken, replace the needle.
Then, thread the upper thread properly, and continue the operation.

I'm guessing it is because the tension is not just right, the bobbin might not be the right size, the thread type top and Botton might not be the same, or you just might need put in a new needle the right size.

Hi. You "feel" that the machine is threaded correctly? You should probably completely pull the thread out and start over, making certain that it is threaded correctly. Once that is done, double check to make sure the thread is pulled all the way into the tension discs. Make sure also that you have lowered the presser foot. Is the bobbin inserted in it's case correctly? Every aspect is critical to proper function. You may also want to revue your manual.

Hello

Clean out the bobbin area if there are any thread tangles there.

If the bobbin does not fit snugly into the bobbin case, then get new bobbins. You need class A or 15 and they do not cost very much. Make sure they are plastic and not metal.

Refer to the maintenance section of the manual - see the configuration of the bobbin case and shuttle race? The bobbin case as an extending arm and the race a notch. When inserting the bobbin case into the shuttle, turn the handwheel so the needle is at it's highest position. Then lift the lever on the back of the bobbin case and insert the cast into the shuttle, arm pointing straight up toward the bed of the sewing machine.

Now thread the machine with the presser foot up - always - and see if the tangling stops.


There should be a tension setting for your bobbin thread, as well as your top thread. It sounds to me like your bobbin tension setting is not in sync with your top thread.

most common solution to this is to remove the top thread completely from machine and re thread it with the presser foot UP not down. This will allow the top thread to engage properly in the top tension disc

Check the bobbin tension and that the thread is tight around the bobbin. Make sure that the bobbin is in the right way around - the bobbin thread should double back on itself coming out of the bobbin holder.

What kind of thread are you trying to use? Is it a decent fresh thread? If, it is old, throw it out and buy some fresh quality thread. Usually, cheap thread is the problem.

It could be your top threading, your thread tangled, or your thread is old. Try different thread and do this test, with the presser foot up, pull the top thread, it should move smoothly, now put the presser foot down, pull the thread and it should barely move. This usually seats the thread in the tension discs. If, that doesn't do it, insert a new needle.

Ensure that you have routed the bobbin thread properly. Also, if the bobbin case is not installed properly it will give you this problem. Ensure that the protrusion is touching the spring on the body of the machine.

The top of the machine is not threaded correctly. First raise the presserfot then rethread the machine. Bottom looping is usually caused by a lack of top tension. There could allso be a bur on the hook.
