Whirlpool Dishwasher

Hi, I have a Whirlpool Dishwasher Tall tub, Model#GU1108XTLQO
The Sani-Rinse lite keeps flashing.
I tried power off and on, nothing changed.
When I pressed Cancel button, both Sani-Rinse and Cancel buttons are blinking.
What else could I try?

Close the door within 5 seconds hit the heated dry, then normal buttons, then hit cancel. Computer should reset.
Problem originated with low temperature water, just check.
If this fails to work, you have a stuck keypad, probably warped, just order a new one, or you can unplug keypad ribbon cable, clean and re-install.
