Here is the parts breakdown
Replacement parts for WHIRLPOOL GU2400XTPS7 Undercounter Dishwasher | AppliancePartsPros.com

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.
