To clarify on that part, yes, a dealer could deny warranty work for something like a black tank valve you attempted to fix yourself and then you bring it in for warranty work specific to the black tank valve. However, if the water heater went south and everything is OEM and still under warranty, they cannot deny warranty for the WH even if you fixed your own black tank valve.

I would just choose to fix the valve myself also, given the OPs distance from the dealer. Shouldn't be very difficult or costly to replace.
