Low pressure from jets

Hi There, I'm a newbie here and a rookie with fixing hot tubs.
I just picked up a used 2002 Down East Providence Spa.
It runs on 220 it has one pump with low and high speed.
It is a balboa control system (light leader board).
I'm having trouble with low pressure form the jets.
I can hear the motor run in low and high. The high setting has the pressure of a garden hose.
The jets are open, some are even missing so they are open.
The filter is removed, still low pressure.
I suspected possible debris clogging the impeller or a broken impeller.
Its not that. I thought possibly a broken slice valve. Those seem fine.
Any suggestions on what to check next? Could the circuit board need replacing? Can that effect the pressure?
Thanks Ted

Replace the missing ones and your pressure should return. Your system is wide open with missing jets - same logic akin to having a broken water main on your street and your house has very little pressure.
