There are a few things you can try -
1. Extend the bobbin thread longer outside and push it away from you.
2. When you make the Stiching pressure lever down then see whether it sits properly or is lose and creating gap.
3. Clean the bobbin seat. Check for its free movement.

If the solenoid has failed the fuse may not be affected. A solenoid is a big switch so they can fail without blowing the fuse. You may need to replace the solenoid.

To be sure it is top thread, suggest you try a thread of a different color other than the bobbin.

Assuming its top thread, you need to increase top thread tension.

Other causes; Uneven feed of top thread can cause nesting of top thread. The machine uses a horizontal spool for top thread. Be sure you use a spool cap that is as big or larger than the spool. Pay particular attention to threading instructions on which direction the thread drops from the spool. If backwards, flip spool.

See following video, testing tension

hi there
regarding Error E924 at JUKI control it means Motor driver failure ( Motor driver has broken.) or you can first check motor connection if connected secure or there's lose connection. other ways try to change motor with new one or check control box only with working machine to confirm Error coming from motor or control box.

Turn it to either extreme and then see if the feed dogs hit the plate when you hand turn the hand wheel towards you. Sometimes the feed dogs or plate have been replaced and they have set the stich length so that the feed dogs won't hit the ends of the plate.

If straight stich slide plate is in position only straight stitches are available.

See pg 31

With the needle, bobbin and bobbin casing removed, Force it with the hand wheel in the normal direction of travel. You can't break it. It will free up. Then run it for 30 seconds at full speed. If it does it again, it needs serving and the timing adjusted.

Three beeps that repeat after a pause and occur when you power on your computer indicate a problem with the system memory. Three beeps that play and then stop as the computer starts successfully mean that the BIOS was restored.

You should make sure it is grounded. Also, is it getting oil from the pan? Blown fuses usually mean there is an overload in the motor. Check that the belt is not too tight.
