The kitchenaid dishwasher (model KUDC25CHSS1) appears to have the 'child lock' engaged on the led display panel. The 'energy saver dry' light is flashing red and when I attempt to push 'cancel' it only...
On my unit, I had the same problem (child lock LED on, or flashing.The cancel process of pushing anything was not possible, as a bad/stuck switch prevented any input from the control panel buttons.
The underlying cause of the problem turned out to be a faulty switch associated with the "Light China" button. I determined this by removing the control panel from the door and using a digital multimeter with OHMS and DIODE settings, was able to check each individual push-button switch using the following table to check the 12 switches (applies to the KUDC25CHSS1 model).
There are 2 ribbon cables, it is the larger of the two cables you need to check. Pin 1 is noted on the ribbon. You can use 2 normal sized paper clips to insert into the ribbon cable and make your connections. (My Ohm meter has aligator clips on its leads which helps a lot...maybe another set of hands would help if you don't have these kind of leads).
-Using OHMS: the reading should be infinite (open circuit, so no reading/no connection inside the switch) when not pushing the button, otherwise you will receive a reading when you push the switch.
-Using DIODE/beep: Ensure polarity is followed in the table below. When connected, pushing the associated button will cause a beep to occur, otherwise there will be no beep and no reading.

All my switches checked out OK, except for the "Light China" switch. On the OHMS settings I was never able to measure an open circuit for that switch, which means the switch was always closed. or connected.
I noticed that "Light China" was pin 2 and "Rinse only" also used pin 2, which happen to be cycles I never use. With power turned off, I carefully removed some of the plastic surround of the matching connector on the Control Board right next to it's associated Pin 2 all the way to the bottom. Then I carefully bent over pin 2 as close to the connector base as possible. Making sure all the remaining pins were straight, I plugged on the control panel ribbon cables and all is well again.
Prior to trying this I was resolved that I needed to buy a new dishwasher because I wasn't going to pay over $350 for a new control panel. Instead, I eliminated 2 unused cycles at no cost, and maybe I can get some more use out of this dishwasher.
