"in the states, Canada, Aus etc"
I can't speak for Oz, but in the US, most newer washers, with a few exceptions like Speed Queen/Huebsch (top as well as front loading) use a PITIFULLY small amount of water to "wash" the clothes, no matter what cycle you select. My 2012 Frigidaire FL fills to about three-quarters of an inch of water in the empty (!) drum on the "Normal" cycle and maybe up to two inches on the "Bulky" cycle. Like Pierre's Whirlpool FL, it also has no onboard heater. When the "Hot" temp is selected, the initial fill is with hot tap water but if it needs to add additional water during the first few minutes of the wash cycle, it does so with cold water only, thus dumbing down the "hot" temp to what used to be warm.
I solve this annoying problem by having a two gallon watering can filled with hot water on stand-by. Once the machine has all of it's two cups of wash water in the drum, I dump the hot water in the watering can into the machine via the detergent drawer. Sounds like something out of the century before last, but it's the only way to actually get the clothes truly clean.
Our pencil pushers in Washington need to come up with something better than prohibiting modern washing machines from using a decent amount of water in order to save the planet.
