Check to be sure you don't have the spa on 'spa lock.' If the regular panel is working, then you don't.
It might just be unplugged: did you get Ozone, Spaudio or a remote control? Those all plug into the same area as the Aux panel so they may have simply overlooked the one wire.
In any event, it will be taken care of...
Glad you're enjoying the new tub !!
