Verdict

The Bosch SMS6ZDI48E Series 6 is a 60 cm freestanding stainless steel dishwasher featuring a 13 place setting capacity, a Class C energy efficiency rating consuming 74 kWh per 100 cycles, and a water usage of 9.5 liters per Eco cycle. Its main advantages include the advanced Zeolith drying system for bone-dry results even on plastics, an Extra Clean Zone in the top basket for heavily soiled items, 8 wash programs alongside 4 special options like SpeedPerfect+, a quiet EcoSilence Drive motor operating at just 42 dB, and smart control compatibility via the Home Connect app. On the downside, its premium Class C energy rating is slightly lower than some top-tier Class A alternatives, it lacks a dedicated cutlery drawer in favor of a traditional lower-basket cutlery basket, and it carries a higher initial purchase price than lower Series 4 models.
