I've been curious about how much it costs to run the dishwasher after your earlier post, CCF. Here's what I found from the SF Gate:
Multiply the wattage of your dishwasher (most models fall in a range between 1,200 and 2,400 watts) by the number of hours you run it each day. Divide this number by 1,000 to find the number of kilowatt-hours the dishwasher uses. Multiply this number by your cost per kilowatt-hour to come up with the daily cost of running your dishwasher. For example, suppose your dishwasher is rated at 1,800 watts, you run it for two hours a day and your electricity rate is 13 cents. Multiply 1,800 by 2 to get 3,600 watt-hours, or 3.6 kilowatt-hours. Multiply this figure by 13 cents, resulting in 46.8 cents. So it costs you just under 50 cents a day to run your dishwasher.
Those are pretty much our Dishwasher wattage and costs per kilowatt hour. Fifty cents a day.

Run your dishes at night. There are many reason to do it. The Kitchn lists three good reasons for delaying the cycle until after you’ve gone to bed. 1. The humidity is better handled by your AC when there isn’t as much natural humidity in the air. 2. You can avoid the sound because you’re sleeping. 3. It can be cheaper. The cost of your energy consumption varies a bit based upon the time of consumption, because some utility companies arrange their pricing so peak hours cost more, either by charging a variable transportation fee or just adding a demand charge.
Not sure if you run yours at night, but this seems to be one answer.
And this from the SF Gate: Air-Drying
Select the air-dry cycle instead of the heat dry cycle for drying the dishes after the load is complete. If you don't have this option on your dishwasher, when the load has finished washing, turn the dishwasher off and open the door a crack to let the dishes dry. This keeps available heat inside, but allows the dishes to air-dry. This saves about 15 percent of your total dishwasher's energy use.
Saving 15% of 50 cents isn't impressive to me, but maybe the combination of running it at night and using air dry could take the load of your A/C?
Our dishwasher beeps when it's done and wakes us all up. We're still struggling to make it stop, but both DD and I have been known to yell, "shut up" to the dishwasher in the middle of the night!
