PROBLEM: WON’T RUN AND LED ABOVE KEY(S) IS BLINKING
Stuck key(s) or shorted circuit(s) in keypad.

Checking keyswitch contacts:
■ Unplug dishwasher or disconnect power.
■ Remove connector P1 from the control board.
Using the table below, measure the resistance across the switch when the key is pressed.
NOTE: The meter must be connected with the proper polarity.

If using an ANALOG readout meter:
The resistance reading should go from infinity (open circuit) down to a readable ohm level.
The level may be different depending on your meter, since there is a diode in the circuit.

If using a DIGITAL readout meter:
The resistance reading should go from infinity down to a readable ohm level.
The level may be different depending on your meter, since there is a diode in the circuit.
If available, you could use the “Diode Test” function of a digital meter, which will give a voltage of about 1.2 VDC during the test.
➔If any switches fail this test, replace the console panel/keypad assembly.
➔If all switches test OK, replace the machine control board

That is an outstanding analysis, Willie! I am truly impressed!  

After much weeping and gnashing of teeth, I was finally able to find something on the C5 error in this ancient-of-days electronic monstrosity and it's pretty close to what Sublime Master Willie's well-reasoned conjectures...
