Hi Bing, thanks for the review. We're sorry to hear this has been your experience. Please know that your feedback is very important to us and will be shared with the appropriate teams for additional consideration. Your dishwasher is designed to dry using the PureDry® condensation drying system. This is an energy-efficient, closed drying system that does not pull in outside air or use an exposed heating element. This process 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 should 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. To improve drying results, we recommend turning on the Intensive Drying feature. For any product-related inquiries or support, please contact Bosch Customer Care at 800-944-2904 for real-time assistance. Thank you.
