No water coming into hopper but supply lines good, water inlet valve just replaced new, and rest of machine seems to work fine. Is it possible that not all the water is drained out and as a result a sensor will not engage the valve to open?
You will want to check to make sure that the pressure hose is not kinked or clogged, and check to make sure that the dome that the hose connects to on the tub is not clogged. If this checks ok then you will want to check to make sure that you are getting power to the water valve. If there is no power then you will want to check to make sure that the timer is sending power to the valves.
