I remain to be convinced: A dishwasher uses an average 18l per cycle, a bowl uses about 6l. Dishwashing happens twice a day so I use 12l and no electricity.
How much water do need to run before you get hot water at the tap? This will depend on how close your boiler/hot water cylinder is to the kitchen sink. I haven't measured mine but it does add up as there is about 6m of pipe to my cylinder. All that water has to be heated. Not all the water used by a dishwasher has to be heated, the first rinse water is cold.
