Retiming a machine needs to be done at a sewing machine repair shop

Timing these machines gets pretty involved such as in just removing the covers. You need a grounding ******** your wrist as the cables all need to be unplugged and you don't want to send a static charge from yourself to the circuit boards. They are expensive. Then you need special sized metal pins to pin several pinning points so the needle, hook, stepping motors and feed dogs all co-ordinate with each other. Also several places need certain guages to set less than .1 millimeter size distances between different places to avoid other problems. You also need several sized torx screwdrivers and the knowledge to adjust the upper and lower tensions. The upper tension alone has at least 3 or four places that need to be in the correct position.
All of the above has to be done in a certain order also.
Its complicated enough. If someone is going to walk you through this over the phone expect it to be complicated. Even if you had a copy of the manual (which could be a copywrite infringment on newer machines) you can expect it to be difficult.
My advice is to leave it to the professionals to have it done right.

First the simple solution. Make sure your needle is inserted flat side to the back and all the way up.
The only other thing I can think of is that your hook is out of time and this will take a technician to re-time it. You may need to take it in for a servicing.

I would start out by putting some cleaner (409) on a q-tip and run it everywhere the thread touches. Guides, tension discs, the under side of the needle plate gets missed alot. Around the hook casing. Then I would just keep sewing on scraps, I know this wastes thread but eventually it will clean itself. A very close zigzag satin stitch would work best.

Hi, it may be possible that you put the bobbin in the case upside down and its turning the wrong way. Flip it over and try it. When looking at the bobbin in the case from the back and you pull the thread, it should turn clockwise.
Hope this helped as anything else may take a tech to diagnose.
