Fresh fill leaking and overflowing fresh water tank

On my 2019 372rd, my fresh water tank has started to leak out the overflow. The only thing I can figure is the tank fill power fresh valve is leaking. Has anyone else had this happen? Pictures are front and back. Looks like it might be a bit tight to replace...

I take it you're hooked up to the City Water connection.
That can happen if the check valve in the water pump isn't closing properly, either because it's bad or possible dirt stuck in it will allow water to flow backwards thru the pump and fill the fresh water tank.
Running the water pump should clear any dirt.

Ken,

Agree with Michelle's response. I have previously changed a pump for the same issue.

Thanks to both responders, spot on advice. I swapped out my water pump with my spare and problem solved. I would not have thought about the pump being the issue. Thanks, you saved me from opening a can of crimped pex worms to fight a valve that would not have solved my problem. I appreciate this group!

I have water dripping from that valve when I set it to NORMAL, I'm thinking it has froze, as I am using the RV now. Does anyone know where i can buy a replacement? Locally? Also, my pump froze last night. I have a space heater in the compartment, and it has thawed. I turned the water on and the pomp kicked in, and I got some out. I shut it back off. waiting 10 minutes, and tried again with no water. The pump is running like it is trying to prime, but it is not priming. Ideas anyone? LOL I'm working today, but need to tackle this repair tomorrow, as we still have 8 more days in the RV before we return home. Luckily, starting today, there is a warming trend the next 6 days here in upstate NY.
