Dishwashers are incresibly simple machines if you exclude the PCB.

Your machine drains, so the drain pump works. Your machine fills, stops filling, and heats. So the magnetic valve that "lets the water in" works. Also whatever controls the amount of water (not familiar with your brand) likely also works. And the heating element is also fine.

The next thing hat would have to stat is the washing pump. But it doesnt. That could mean the pump has an issue. This is not unlikely, the can be damaged if something slipped your filter or evem if you wash lots of floury or similar stuff. Thats like sandpapering it for years. The pump is usually among the most expesive parts, but depending on what you got it might not be necessary to change the whole thing. Altough repairing a pump is kinda difficult if you never done it.

I dont really understand why you thing its the door latch? I dont know your brand and i'm not really a technician but the dishwashers I know have a simple on/off fuction in their door switch. "If door is open, do nothing" so it shouldnt even drain or fill if the latch was the issue. Again, not sure if that is true for your machine.

It could be an interlock that prevents the machine from sending water all over your kitchen by checking the latch. If the switch is bad, it might be stuck in the off position, as that would be the safest way to have it designed.

Could be, but I find it strange that the machine then starts in the first place. Like, in the washers I know the door switch is (simply put) the second thing in the line with the first being the Power On/off switch.

So the machine shouldnt even drain/fill/heat if the latch was at fault. Which also makes sense because it prevents the kind of energy waste OP is experiencing.
