Wash time / soil level is not adjustable on AquaSmart. User guide advises the 'regular' cycles are 12 to 15 mins. Lifestyle cycles aren't detailed on that point.
I've used Regular in HE mode once thus far. Am otherwise investigating the various cycles for specific loads/fabrics, which run in conventional mode.
Water level sensing for HE mode seems to be based on when the bowl floats, although there is a minimum level.
Conventional mode sensing varies per the cycle purpose. Sheets, as covered above, fills to a specific high level, then apparently drains if necessary to get some fabric resistance sensed on the impeller. Bulky cycles also fill to an initial high level, and may fill higher if the load senses for such.
Jeans, Easy Iron, Whites, Colors fill initially to bowl-float, runs some agitation for sensing, then calculates a higher fill level accordingly. The fill level is re-sensed for a deep rinse, it doesn't just go with the same level as the wash. Fills directly to the target level after sensing ... no futzing around with spurts of filling like many of the HE/impeller machines nowdays.
Probably takes a little more water than Calypso for HE mode. Considerably more in conventional mode although the load isn't always fully submerged and floating ... must have some contact with the impeller for good action. Sheets and Jeans (ran just three pairs) had too much water IMO.
