There is a trouble shooting document behind the kick panel at the bottom of the machine. Follow the steps to determine which component is at fault. It could be corrosion at the P1 connector:
My whirlpool dishwasher gold GU2475XTVQ0 had rapid blinking lights that started with the "4 Hour Delay" LED and changed to others when other buttons were pressed. The machine would not run. I followed the instructions located behind the kick panel and verified the keypad was the issue and not the control circuit by elimination.
The big surprise for me was that when I used a straight pin to resistance check all of the buttons, they checked out OK. I reconnected the 14 pin connector (P1) to the control and found that the buttons/LEDs were behaving correctly! I believe that pushing the straight pin into the 14 pin connector removed any corrosion in the 10 year old device and permitted the keypad to communicate with the control again.
I reassembled the dishwasher door and it ran with no problems. I was ready to replace the keypad for $150, but didn't have to!

QuietGuard3: Clean light flashing 7 times? Press Heated Dry, press Normal Wash, then press Heated Dry again and press Normal Wash again (that's 4 button-presses) and that should fix it.

I may have fixed my similar problem- I opened up the machine to get access to the control panel as tech17 advised- then in addition to disconnecting the mylar ribbon, I disconnected all the connections to the control panel.... keep in mind to ensure not to confuse any of the connectors you disconnect. Running a cycle at this time... seems as if working.. can't tell if water is running or just the motor- -- HA! -- i confirmed no water being pumped in.... We then found a float switch (Item 30 on schematic) that got loose from its casing on the front interior right lower side... we put that switch into its proper place and now ALL IS WELL!!!! Yippee!!!

check the filter and make sure you are using good soap tablets. Check also that the salt container is full.

Try resetting it. Locate the switch in your breaker box, and flip it off- then on again. Hope that works!
SOURCE: unit will not run. cannot enter diagnostic mode.
i would say that you have a bad touch panel..99 percent positive
