Drying Features
The Avanti includes a rinse aid dispenser to aid in drying and prevent spots, while the SPT boasts a heating function during its drying cycle. This feature can enhance the drying effectiveness, ensuring that dishes come out drier and cleaner.

This could influence your decision if drying performance is a critical factor for you.
Energy Efficiency
Both dishwashers are ENERGY STAR certified, indicating they meet or exceed federal guidelines for energy efficiency. This certification means that both units can help save on utility bills while being environmentally friendly.
