Baby lock esp?re embroidery machine the top thread keeping wrapping around the bobbin when it starts sewing

SOURCE: Brother 2001 sewing and embroidery machine.

The fact that your machine is turning hard says you still have some thread inside the machine that is binding up and activating the safety device. It must turn easily before it will work properly again.
Sometimes the machine must be disassembled to remove these threads.

IT PROBABLY IS THREADED INCORRECTLY. GO SLOWLY BY THE DIAPHRAGM AND MAKE SURE IT IS THREADED CORRECTLY. ALSO MAKE SURE SPOOL PIN HOLDERS ARE IN PLACE THAT HELPS TO GUIDE THE THREAD CORRECTLY.

Insert the bobbin case without a bobbin to see if it will go all the way into the locked position. If it does,the bobbin case and basket are okay.
Check inside the bobbin basket(where the bobbin goes) and see if there is thread or lint wrapped around the spindle the bobbin case sits on. If there is, remove it. If there isn't ,then the bobbin is probably sprung and needs to be replaced.

Have you checked the top thread is correctly placed in the spring of the bobbin case?

SOURCE: Not picking up the Bobbin thread

Sounds like you have to take off the throat plate and clean out threads under it.  Sometime they ball up and prevent the needle from going down and catching the bobbin thread. You can't see themuntil you take off the plate.  Follow the directions.  It is easy.
