I have a Kitchen aid model KUDS01DJBL0 There seems to be a two fold problem: 1) cannot set reset cycel even tho the panel lock is off. When you close the door the light for normal goes on but you cannot select another cycle even after opening the door. 2) Once you start the diswasher it steams, heats but the water does not seem to be flowing. I've checked for obstructins with the float inside the machine, there are none. The water arms are all free. I'm perplexed. I'm not sure if it would be the water valve assembly or the control sensor panel. HOw do I differentiate?

You have to touch certain of the front panel touchbuttons in a certain pre-specified order. This sequence will cause the built in computer to initiate a "Diagnostic Mode", the repairman will step quickly through all the cycles at 1-2 minute intervals so that he doesn't waist his time. At the end of the diagnostic steps the computer will revert back to normal mode. You will need the "controls and cycles diagnostic sheet for repairman" map-sheet to be able to do the above, this sheet was with the machine when you first bought it.
I suspect the computer in your machine is stuck in the "Diagnostic mode" and is not getting out of it.
