Verdict

The Bosch SMS6ECC12E Series 6 is a 60 cm freestanding dishwasher featuring a 14 place settings capacity, an ultra-efficient Class A energy rating (54 kWh/100 cycles), and a low water consumption of 9 liters per cycle. Main characteristics and pros include its exceptionally quiet 42 dB operation, a customizable MaxFlex basket layout with a Rackmatic top basket, a VarioDrawer cutlery tier, smart Home Connect Wi-Fi control, an intensive Extra Clean Zone, and Efficient Dry automatic door opening. However, potential drawbacks include a higher upfront cost, long Eco cycle run times reaching 4.5 hours, and a feature-dense menu system that may feel complex to navigate.
