Fresh water filled, but not by me

We have a rockwood 8325 ss 2016 new in January it has 2 grey holding tanks the one for overflowed and kitchen sink had about. 3 inches of water because I didn't open the drain. Went under camper and valve open and drained water ok. But checking the fresh water tank as a routine ,I check all tanks, the fresh water tank was showing full with all lights on. I didn't fill it, it has always been empty since new. Can their be a conection between the grew water tank and the fresh water tank?? Which would not be good or is their a valve to fill fresh water tans from the normal hose connection that I don't know about?? I am worried that grey water is in my fresh we're tank.

no chance grey and fresh are connected in any way . have you opened your fresh water tank drain ? if so did water come out . if not then the sensors are reading wrong .i know when my tank is empty it reads 3/4 full but as soon as i add water it reads correct . stupid sensors . if yes then the check valve on the pump maybe allowing water past and into the tank

Occasionally the back flow check valve in the water pump will not seat and allow some water to flow into the FW tank when connected to public water. To remedy this, disconnect public water open faucet until water stops. Turn on water pump and let water run for a min. Shut off water pump and reconnect to public water.
