Dishwasher is not drying

My dishwasher recently stopped drying my dishes. I called for a repairman to come check it out and he ran diagnostics on it and said it’s all fine. He even showed me on his computer and when he ran the test the heating element worked! However when the dishwasher runs on it’s normal cycle you can tell the heating element doesn’t turn on…especially when it’s suppose to be drying.

So I’ve replaced the heating element and control board and it’s still not working. I’m trying to take a shot at the high temperature thermostat but I’m having a hard time finding where it’s located or even the part number for my model.

I’ve research and troubleshooted as much as I can tell, but am still having no luck. Any ideas on what else I could do, or even point me in a direction as to where this high temperature thermostat could be on my model?

Thanks.
