Ok there is one water hose connected. There are a couple of things to try. One is there is a float / sensor in the bottom on the inside of the unit that if it is stuck in the up position will cause the symptom you described. The other would be a failed solenoid on the wate inlet valve. With the main power to the dishewasher off You can check the soleniod to see if it has 2 - 12 Ohms resistance between the two coil terminals. (one wire will have to be disconnected to perform this test) If it passes the resistance test slide the teminals partially on so that the metal is still exposed on the solenoid terminals and turn the power back on. Then check for 120V to chassis ground on both terminals. If you have the 120V then either the solenoid plunger is stuck or the water valve internal diaphram center hole is clogged. Just make sure to reattach the terminal correctly. I have been known to give these water valves a nice rap with the handle of a big screwdriver to attempt to unstick them. Sometimes it works sometimes it does not. Lastly if you never saw the 120V then most likely as I said initally the inside cabiner float is stuck in the up position. You can grab this and gently lift it up and down. It should fall to the bottom position under it's own weight. If it does not then you need to clear the gunk preventing proper operation. It should also click near the top position as you raise it and again as it is lowered. (Unless it is an electroinc sensor) Pretty sure yours is mecanical.... If it looks like a finger sticking up it is electronic. If it looks like an inverted measuring cup without a handle it is mechanical. Lastly if you have verified the water inlet valve continuity and power along with the float / sensor yet you still get no water losen the water line and see if there is water pressure. Hope this helps.
