A:Answer Hi, thanks for your question and for your interest in Bosch! Our 300 Series dishwashers are designed to dry using the PureDry® condensation drying process. This is an energy-efficient, closed drying system that does not pull in outside air or use an exposed heating element. It works by heating the dishes with hot water during the final rinse. The cooler stainless steel pulls moisture from the dishes. The inside of the unit will be wet at the end of the cycle, but the dishes will be dry. It's important to note that plastics don’t retain heat as well as other dishware materials and don’t dry as well. If you have additional questions, feel free to contact Customer Care at 800-944-2904 for real-time assistance. Thank you again for considering Bosch!
