Verdict

The Bosch SMH4ECX28E is a 60 cm, fully-integrated Series 4 dishwasher with a 14-place setting capacity, operating via a durable EcoSilence Drive motor. It features an outstanding Class A energy rating, consuming only 0.543 kWh of electricity and 9 liters of water per eco cycle. Main advantages include its ultra-quiet 42 dB operation, Vario sliding hinges designed for seamless integration in low-plinth or tall cabinetry, flexible loading via the VarioDrawer 3rd cutlery rack and a 3-level adjustable Rackmatic top basket, and automated moisture control using the EfficientDry auto-door-opening system. On the downside, the Eco program cycle is quite long at 4.5 hours, and drying performance on plastics may be less effective compared to higher-end models with active heating elements.
