I do this too. I kinda always thought it's just part of how you operate a dishwasher :) First time I opened it right after its cycle, a huge cloud escapes, so it figures that otherwise it would condense, no?
Another tip then, I don't just open it a few inches but all the way and pull out both racks. That way all the steam escapes within a few seconds and you can close up the dishwasher again. You do need a bit of ventilation but I just open my balcony door. And then, there's a few cups or glasses that have concave bottoms so they gather a bit of water. If you blow hard on them while everything is still hot, the drops will fly somewhere (it's just water), and those glasses will become fully dry thanks to the last bits of heat.
Another tip. If you wrap it up real good so no soap can get to it, you can easily cook a piece of salmon in your dishwasher. It's not a great way (cooks too hot, for too long), but it does work and that's awesome.
Another tip. If you got a compartment for a "shining agent", you can put a mix of white vinegar and ethanol in it. It works. Both of the substances easily evaporate in the heat so you won't get a vinegar smell or anything (unless you use balsamic--good luck with that). An expensive commercial shining agent might work even better, I never tried them.
Yet another tip. Maybe you have a built-in water-softener whose ion-exchanger needs recharging by pouring dishwasher salt into another compartment. The only difference between table salt and this stuff is that the granules are big so it dissolves slower. So, buy big granules table salt instead (the stuff used in table salt grinders), which is much cheaper.
Another other tip. You'll probably still do some cleaning by hand, when you need a specific utensil or something. If you use a plastic dishwasher brush, you can put that one in the dishwasher as well to clean it. I'm unsure why, but I find brushes to last a lot longer when I occasionally clean them in the dishwasher.
If you can trust your dishwasher to not leave weird residue on your stuff, you can also use this method to clean plastic hair-combs every once in a while.
A dishwasher really is a magical device. You can even put some lines of source code in the cutlery rack, and they'll come out with less bugs. True fact.
