Verdict

The Bosch SMI6ECS12E Series 6 is a semi-integrated 60 cm dishwasher offering a spacious 14 place setting capacity, a premium stainless steel interior tub, and an exceptionally quiet noise level of just 42 dB. Key characteristics include an outstanding Class A energy efficiency rating consuming only 54 kWh per 100 cycles, 9 liters of water consumption per Eco cycle, and advanced integration with the Home Connect Wi-Fi app alongside specialized hardware like the MaxFlex basket layout, 3-stage Rackmatic height adjustment, a dedicated VarioDrawer cutlery level, and a triple-nozzle Extra Clean Zone for stubborn stains. Main advantages include highly flexible interior loading, significantly reduced operating costs, specialized program downloads, and the automatic door-opening EfficientDry system that delivers excellent drying performance on all items including plastics. On the downside, the dishwasher lacks a physical floor light projection to track remaining cycle progress from the outside, its highly efficient eco-cycles carry an extended running time of 4 hours and 30 minutes, and some users have noted initial configuration quirks with its smart application pairing.
