Dishwasher was installed less than a week ago.  I was unfamiliar with the new drying technology -- where after rinsing, water drops on dishes are drawn to stainless steel sidewalls where they condense and slide down the walls into the drain -- instead of a heating coil at the bottom of the cabinet.  I like the advantages of this new drying technology: less energy consumption, no melting of plastic dishware due to heating coil, and no steam venting out the top and front and warping the underside of a countertop.  
This technology only works and works well when the "water boost" setting is used.
