3. Product Features
The Rinnai RKW-405A-SV dishwasher is designed for convenience and superior cleaning performance, incorporating several innovative features:
3.1. Smooth Rack (Lower Basket)
The lower basket features clear position signs and shorter pins, making it easier to load various types of dishes without confusion. This design not only simplifies placement but also optimizes water flow to ensure thorough cleaning of every dish.
3.2. Circle Rack (Upper Basket)
The upper basket is designed in an arc shape, aligning with the rotating nozzle's movement. This significantly increases the volume of water directed inside glasses, ensuring that even glasses at the ends of the rack are thoroughly cleaned. Note: The number of cups that can be set and the rack shape may vary depending on the specific model.
3.3. Vital Sterilization Wash Function
This function adjusts the water temperature to optimize the activity of enzymes in dishwasher detergent. This effectively dissolves and lifts oil stains, making them easier to remove. By precisely controlling the temperature, the function maintains the sterilization performance of the detergent while also reducing power consumption, offering an economical and effective cleaning solution. This feature is available in Standard, Intensive, Night Eco, Reservation, and Silent courses. Test results indicate over 99% sterilization effect.

The 'All-Top Control' centralizes all operation buttons on the top panel, allowing for comfortable operation without bending down.
