3.4 Detergent Usage
Use standard dishwasher detergent pods, liquid, or powder. The integrated softener allows for the addition of dishwasher salt to reduce spotting, lower detergent usage, and extend the machine's lifespan.
4. Deep Cleaning and Drying Technology
The dishwasher is equipped with 3 high-pressure spray arms that deliver full 360° coverage for a thorough clean. All cycles, except Fruit, alternate cold and hot water 3-4 times. The 167°F high-temperature wash effectively dissolves heavy grease. Following the wash, auto hot-air drying (except for Fruit and Delicate cycles) ensures dishes and baby bottles come out sparkling clean and completely dry.

The Air Refresh option provides an additional hour of heated drying. After this, the dishwasher automatically enters a 72-hour intermittent ventilation mode, which helps maintain spotless dishes, eliminate odors, and ensure prolonged dryness.
