Hi, my name is Peter.
You should have 120 volts to the water valve during the fill cycle. Check the float switch in the front right corner for continuity. If the float switch is good and no 120 volts at the water valve then I would ohm the wires from the board to the water valve. if they are good then you have a defective control board.
You may send additional questions directly to me.
