This could be a tough one. The freshwater is only through the master power panel and the switches on the side on this model. So if you have power at the switches, then you should have power at the wiring, unless it is in the breaker on the panel. The aerator, does it show a Fault Signal on the dash? If so then you either have a wiring problem, or a pump failure. These are amperage regualted, and it may run hot wired, though not through the protected system. If it is not getting power out of the dash, then try to see if the Accessory switch is used. If not put the aerator on it and run it manual to fill, and use your recirculator on the timer.
