No water to icemaker or in-door dispenser

Side by side with dispenser has lost water to dispenser and icemaker at same time. Refer is on a boat and a bitch to get to so am trying to narrow things down before moving it.

Ice dispenser works, lights in dispenser work and filter reset works. Had load of ice in maker that didn't eject right away but eventually did after a day or two of use with bought ice and no water refill after ejecting.

Hard to believe both sides of valve would fail at the same time or is there something common to both in the valve?

Is there anything common to both ice water and dispenser water other than the board behind the dispenser?

Thanks, Jon
