Good Morning

I'm not sure on your exact model ,

Sometimes there is a valve you need to open to fill the fresh water instead of using city water .

If you are using the gravity fill , there is a vent hose which may be kinked or collapsed

I can see a Val that says fresh water tank filled and local Supply but either way it feels like a vapor lock there must be a kinkline somewhere where do I look for that
RV Mechanic: Nachum Wagschal, RV Mechanic replied 1 year ago

put it on fresh water fill , to fill the tank

it is very possible there is a problem with the vent hose , sometimes there are even spider webs that block them

RV Mechanic: Nachum Wagschal, RV Mechanic replied 1 year ago

there should be about a half inch diameter hose coming from your water tank that is your vent hose
