Wonder if the board got wet during the flush? Might dry out and be ok.

Might have but..I suppose every time we've flushed ours it might have gotten a few drops but it is out of the way of the drain, mostly and encapsulated in plastic or epoxy.
Wires get kinda grungy if unit is not cleaned and where they plug together might have gotten damp. there is one wire that has a looser than I like plastic tubing over plug to thermostat, I think.
