The Huebsch has a single pressure switch, so it consistently fills for both wash and rinse cycles in the same way. Ideally, they should have two different pressure switches, one for washing and one for rinsing... but I guess Alliance felt that one was good enough.
I guess I'm a little surprised that it is the other way around for a Duet, but the higher water level makes sense.. more water would equate to less mechanical agitation I suppose.
IMHO, for the Huebsch machines, it's best to adjust it in such a way where, when it is empty, the water just comes up to the lip of the drum. (ie. The Baffle is fully covered in water)
When the washer is filled with water absorbing clothing, the water level will revert back to the "factory full" water level before the switch kicks in.
Does it affect washing performance? I have no idea.. I can certainly tell you that it did certainly affect rinsing performance.. The need to do an extra rinse isn't as necessary anymore with the higher water level.
