WP does offer a Deep Fill option, at least on some of their machines across the brands. The question is, what is the level that the GE fills to? To the top of the basket?
I wonder if the auger does help move larger and more bulky items around better or it's just there to assuage the wary "old school" buyer that they are getting a washer that's familiar. They don't lock the lid for just safety reasons. I would hope it gives a better performance than some of the Bulky-Bedding cycle vids on YouTube of t/l washers that can't turn over a bulky item even once.
When I had the Whirlpool wash-plate machine, the higher water level cycles worked fine with large loads, but a large volume of water for smaller loads let the clothes "float" on the surface of the water and washing performance was almost nil.
Some of the top load machines from LG and Samsung fill completely on certain cycles, Bulky-Bedding, etc. but I've not seen one of these that has a specific "Deep Wash" or "Deep Fill" option.
And then Bob's question is still pertinent, if the hot water is dumbed down to 100F or lower, what's the point of a tub full of cool-cold water? Perhaps for rinsing, which I would like the option of, but if you can't get hot water for washing - even tap temp at 120F filling a large drum like that would end up at least 20F degrees cooler by the time it's full.
