I have the same dishwasher, Make sure you have turned the water valve on for the pipe that feeds to the dishwasher on the wall behind the dishwasher. Failling that just make sure there are no kinks in the feeder pipe coming from the wall, it can sometimes get trapped or bent when you slide the washer back.
Try disconnecting the pipe from the back of the dishwasher and turn it on slowly into a container just to test that it is supplying water when it's connected. Also if you press the start button for 3 seconds it goes into emptying mode and makes funny noises for about 10 seconds then knocks off. The lights you mention are on the very top of the door as you look down on the washer.
I have the manual and it's not very helpful. It says if no water turn the tap on on wall.
Hope any of this can help please let me know.
