Timer knobs are LOOONNGG GONE!! Normal, & Auto cycles offer prewash, a rinse (if soil is heavy enough then it will drain0, then main wash, and two rinses. The dishwasher will also do a partial fill & drain after the prewash, first rinse, and after main wash if needed to purge soil & debris that's sensed. Heavy does a hard preash, rinse, main wash, and two rinses. Each cycle offers different target temps and even varies based upon soil level senssed too. (At least on my Bosch that's 3 years old but I doubt sequences have changed much.) Heated dry is passive and is the final rinsee water temp on this dishwasher. It has an intensive or extra dry that raises final rinse temp even more. My model has what Bosch calls CrystalDry that is amazing using Zeolite. Drying result rival that of KitchenAid dishwashers from the 1950s-1970s. And I can put plastic items anywhere, no conccern about plastic melting. Drying temperature inside cabinet is said to be 176 to 178 degrees F. It's pure dishwasher heaven wasshing drying. Spray intensity is also adjusted for soil level.
