GFI not working-blew 2 30 amp service fuses

On my last trip, someone flooded the sink and water flowed over into GFI (GFI is on front of sink cabinet). Tried to turn on AC later and it wouldn't turn on (just hummed). I didn't immediately put 2 and 2 together, but after trouble shooting I found both 30 amp fuses were blown for 30 amp service. Replaced them and tried to reset GFI, but it wouldnt and no GFI outlets worked. This outlet is the only one with reset on it. I got home, replaced GFI, still nothing. None of the GFI's work. Now when I try to plug anything in, it flips the generator breaker, but fuses dont blow.
I've reached the end of my trouble shooting skills. Everything was working before the trip, so I am pretty certain the water caused the issue. Any ideas for thinks to look at??
