Have you checked Consumer Reports? They sometimes give info like that.
If you want to really know then unhook the drain tube and run a load into a
couple of 5 gal buckets. Repeat for each of the different cycle options.
Probably be interesting to do even if you did find the manufactures claims.
Are you more concerned with just water usage or 'hot' water consumption? If
I anticipate running out of hot water from showers and laundry etc., then I
will run the dishwasher last. My DW will heat the incoming water with the
heating elements if not hot enough.

Hi Kevin -
I am concerned about hot water only. I have two 50 gallons water heaters
- one by kitchen - one on the other end of the house by laundry. The one
in the kitchen serves two bathrooms 90 feet away. I know it is stupid -
but I bought the house this way.
I plan to put one new tankless water heater right next to the bathrooms
and maybe run an insulated line up and over to the kitchen. The kitchen
has a sink and dishwasher - that is all. I was thinking maybe an under
sink water heater could serve the sink and dishwasher.
I am just in the planning stage. I hate waiting 90 seconds for hot water
in the bathrooms. :-) I also hate that I am heating 100 gallons all the
time for two showers - a load of clothes - and a load of dishes daily.
I know - I have too much time on my hands :-)
Money is no object within reason. Also the utility company will give me
$450 for each electric water heater I replace with a gas one.
