Galley Gray Tank sensors
Leave the gray valve open for 1/2hr after removing the hose. Sometimes there is enough moisture on the sidewall to complete the circuit.
It's possible there is food particles from washing dishes and such. You can add a tissue digester, fill the tank and haul it home. Them when you get there use a dump station.
