Whirlpool quiet partner iii does not heat water

my quiet partner iii dishwasher does not heat water for the wash cycle, what systems should I check to fix this. i did not see a thermostat or min heat sensor on the part number.

Here is the parts breakdown

Here is the tech sheet

Try the diagnostics.
Then, I would check the heating element and the hi-limit thermostat with a meter for resistance, see the tech sheet.
If OK
Check the wires going up to the control board.
If OK
Check the thermistor for resistance.

is that the same as the vent? pardon my ignorance, but UIdont see a thermistor in the parts diagram. :confused:
