water not getting to ice maker

changed both inlet valves, did diognostic on old ice maker. replaced with a new one from partselect.I have a cupple notes of interest. One, do not count on the instructions sent with part , I't took me a while to figure out that they do not necesarly apply to my unit. no diognostic light on new unit. and you don't have to follow the same procedures. I finished the project but the added help hindered me more than helped.
