FYI - talked to Entegra and did the following (2020 CS 45W) - There is a hot water line above the fresh water tank that should be shut off if your machine only requires cold water. Access was to remove the fresh water tank cover (right side of coach) and just turn the valve off - this keeps any hot water leaks from the valve behind the washer.
