Yup, that board's toast.
C2 was just about fried completely off.

Just make arrangements, and get it in, as they'll just swap out the board.
No, there's no water sensors, but there is residue on the board, mostly around the capacitor C2. That around the power connector is a clue though. Fortunately, the service techs probably won't have the time to make an issue of it, be in too much of a hurry to get it completed, and won't be able to tell the difference of it's origin anyway.
