Yeah, the standard advice is actually to run your kitchen faucet on hot until you get hot water, before you start the dishwasher.

I'm always rinsing off the bigger gunks of food with hot water anyways as I load the dishwasher, so it's hot already.

At the end of the day it doesn't matter that much. The main point is just, if you have hot water available, it's hard to see why you wouldn't take advantage of that.

I’d assume that wasting a lot of hot water before running the dishwasher negates any price benefits from heating the water with gas instead of electricity. Not to mention the CO2.
