How can I isolate if the problem lies with the Control Board or with
the keypad?

Do you have a manual with a schematic? If not, that seems like
the first thing to get. Try a google search for the make and
model--you might find one on-line for free. Otherwise, check
out the Whirlpool website or call their hotline number.

If the keypad is mechanical, you should be able to disconnect
it and ohm out all the circuit paths. If it is an electronic
keypad, then it is likely beyond what a home user can do. The
most common thing with dishwashers is that they have a cam
driven by a clock motor, and the cam engages little micro
switches. These switches go bad, the lever breaks or bends,
or the switch gets out of alignment. Other common items are
sensor switches that get out of alignment or wear out.

Is the keypad replaceable? Where can I buy one? Is there anything on
the control board that I can check with a multimeter?

Parts should be available. Once you know the part number,
search for it in google, or order it from Whirlpool.
