Older Bosch dishwashers have heating elements, while modern models use the condensation process to dry the dishes in the tub. Instead of a single heating element, multiple dishwashing elements are used to dry the load. It starts at the final rinse when high-temperature water is sprinkled all over the dishes, making them extra hot. When hot, moist air comes into contact with the stainless steel tub, water droplets form. These droplets will simply trickle down to the bottom of the tub, where they will be drained.
