Verdict

The Bosch SMS2ITW12E Series 2 is a 60 cm freestanding dishwasher featuring a 12 place setting capacity, an EcoSilence Drive motor operating at 48 dB, and smart integration via the Home Connect Wi-Fi app. It offers 5 wash programs including Eco 50°C, Auto 45-65°C, and Intensive 70°C, alongside specialized functions like Extra Dry, Half Load, and a personalized Favourite button. Main advantages include efficient performance consuming 10.5 liters of water and 92 kWh per 100 cycles under energy class E, reliable AquaStop leak protection, and intelligent AquaSensor soil detection. However, notable drawbacks include its lower energy efficiency rating, a basic Polinox/stainless steel hybrid interior tub rather than full premium steel, and a fixed lower cutlery basket that reduces overall loading flexibility.
