My water pump went out last summer, leaking into the compartment. In replacing it I noticed the circuit board on the floor also, although at the time I didn't realize it was a circuit board. Fortunately, none of the water that leaked got into it, but I made it a point to raise it up off the floor anyway. Reace told me later that that fix has been done.
