Could you double-check the model number? Brother doesn't list "H23-B1 model 30" or any part of that as a home or industrial sewing machine model number.

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.

I had the same problem with my Shark Euro Pro 7133. My problem was in threading the upper thread. The manual does not quite explain so I had to figure this out the hard way.
In threading the upper thread . the thread first goes down from the spool througt a groove. When it comes up it must catch a silver lever that moves up and down before moving it down againPlease let me know whether this helps.
