you need to establish if the connection you made to the pipework is letting water through, take a hose from your washing machine connect it to your new plumbing and check if water is flowing when the valve is turned on, if it is and you say the d/w is new get a call in for service repair. if no water is flowing its time to go back to the drawing board. the flow meter/jug is next to solenoid valve
