Verdict

The Bosch SMS2HKW04E is a freestanding 60 cm Serie 2 dishwasher with a 13 place setting capacity, operating efficiently with an eco-program water consumption of 9.0 liters per cycle and an energy consumption of 84 kWh per 100 cycles (Class D). Main characteristics and pros include its remarkably quiet operation at just 42 dB, a reliable EcoSilence Drive brushless motor, AquaStop 24/7 flood protection, and smart Wi-Fi integration via the Home Connect app for remote control and monitoring. It also features practical loading options like a height-adjustable top basket and an Extra Dry setting for tougher loads. However, a potential drawback is its standard heat-exchanger drying system, which can occasionally leave plastic items slightly damp compared to premium Zeolith-assisted models.
