Fresh Water Storage Tank Leaking

[Texas Clodhopper]

I filled my fresh water storage tank a couple of days ago using the auto-fill method. Once full, of course, it started running out the tank overflow. I set the inside auto fill control to off but apparently, it didn't turn the valve off since water continued to flow until I turned the park supply off. I know about the overflow drain being too low being problematic and I replumbed that some time ago. I'm running currently just the pump because if I turn the park water on it fills the tank and here I go again. Any suggestions?

Thanks.

See if this is your scenario:

Resolved - Autofill did not auto shutoff!

Came back from a long dog walk to find a pool under my coach and water gushing out the overflow and thankfully not bays, door, windows! Autofill display showed "Ready" and not filling yet it was obviously still filling. It did start a filling cycle before I left for the dog walk. Something...

Let me ask the glaringly obvious question: Is the valve in your wet bay set to auto fill?

Lol...yes, the valve is set to auto fill and the inside switch is set to off. I'm sure it's that solenoid valve stuck open and I'll wait until I'm home to tackle removing the hose reel. Thanks for all the suggestions.

Apparently whatever gremlin was causing my issue moved out. The only thing I did today was move the water valve from manual fill to automatic fill several times so maybe a foreign object was stuck inside the valve.
