Whirlpool Clean light blinks 7 times

My Whirlpool Gold dishwasher’s clean light blinks 7 times. I cannot find the service manual to see how to reset this. I’ve tried several buttons, hitting cancel, then shutting the door. It’s still blinking at me!

To reset unplug it or remove power from it for a couple minutes.

If that does nothing check the heater should be around 20 ohms, the hi-limit thermostat should be 0 ohms, and the thermistor See the tech sheet.
If all OK check the wires that go from theses parts up to the control board.
If Ok
The control boar is probably toast.
