If water consumption isn't something the customer or government cares about, then the customer will choose on other metrics. Americans aren't generally going to buy a European washing machine that takes an hour longer to clean their clothes.
Europeans are going to look at the energy efficiency sticker that by law must be displayed with the machine, either out of altruism, to reduce the running cost, or because the machine with A must be better than the one with G. See the coloured symbols on [1] and the more detailed information if you click one, showing capacity, water use per cycle and typical annual electricity use.
Walmart's site [2] doesn't show this information anywhere.
Walmart does not sell washers, those are all resellers using the Walmart website as a platform, and almost no on would buy an appliance there.
All the energy usage and other details would be on the website of a retailer that actually sells appliances, like Home Depot/Lowes/Best Buy/Costco/etc.
