I pulled the water line to the icemaker, ran water through it, seemed fine. I then jump started the icemaker that communicates to the refrigerator to pump water to the icemaker, and water was sent to the icemaker. This showed the water valves and filter were working fine, and pointed to the icemaker. I ordered the icemaker, arrived quickly, with a couple of wire harnesses, icemaker and new arm. I changed the icemaker, and once I snapped it in place, Vala! The water pumped into icemaker.
