@bajaespuma: Its a cruel no win compromise.
That single knob dishwashers is all anyone really needs. A filter and two wash arms is all anyone needs. A heated wash is all anyone really needs.
But, the market doesn't work that way.
You could either buy a simple BOL DW that would have some unwholesome combination of no water heating (BOL Maytags), short main wash, no filter, fewer water changes, no upper wash arm, ect, ect but would last 40 years at the cost of having your dishware coming out of the machine like it went in the machine
-OR-
You could get clean dishes through a filter, water heating, upper spray arm, normal wash times, versatile racks ect at the cost of reliability/dependability/longevity brought upon by rapid advance timers and its complex interlocking circuits to mimic cycles and sequences that no one actually needs.
I've never seen a single knob fixed timing Whirlpool Power Clean Filter Module DW before, and there is lays the heart of the problem I think.
