Dishwasher won't heat up or dry dishes

We have a portable dishwasher and I noticed the dishes are coming out wet and weren’t hot to unload like before. I opened it midcycle and the heating element was cold.

From what I’ve read, it’s the heating element or the high temperature thermostat. Where would I find the high temperature thermostat underneith?

My boyfriend is going to check the heating element for continuity of the circuit (I found directions on Internet). How do we check the thermostat?

Does anyone have the part numbers for each part?

Just follow the wires that run from the heating element and you’ll find the thermostat, more then likely it’s on the base of the unit on the right perhaps…continuity test both the element and thermostat. Voltage test the lines going to the element when it’s in drying cycle it should be 120v if not then you have the thermostat our or the main control board is bad. Here’s some video’s to help
