I had the same problem in our ACE 30.3 2019.
To trouble shoot, I went to lowes and bought two connection hoses from lowes, and took the the entire faucet to our garage sink.
Before connecting it, I detached the hose that connects from the "mixer" to the faucet head.
I tried blowing through it, (yes, with my mouth) and it allowed air to pass easily. - Well that doesn't make sense. -
I then connected it to the wall, and it worked fine.
WHAT?
I put it back in the coach, and it worked fine.
My suggest is to leave it in the coach, disconnect the single hose that goes to the faucet head, and see if you can blow through it.
It may start working, or at least you know where the problem is not.
Yes - I do expect some you to doubt this happened. I couldn't even explain it to my wife, she thought I was an idiot and it couldn't be true.
