Verdict

The Bosch SMV4ECX21E is a 60 cm fully integrated Serie 4 dishwasher offering a 14 place setting capacity, a VarioDrawer third cutlery rack, and a highly efficient Class B energy rating consuming 65 kWh per 100 Eco cycles and 9.0 liters of water per cycle. Its main characteristics include an exceptionally quiet 42 dB operation, an EcoSilence Drive motor, and smart Home Connect Wi-Fi integration. Notable pros feature the EfficientDry automatic door opening system for enhanced drying, a 3-stage Rackmatic height-adjustable upper basket, and an InfoLight floor beam to signal operation. On the downside, the standard Eco program has a lengthy run time of 3 hours and 35 minutes, it lacks a TimeLight remaining-time projection, and some users note the initial lack of a custom front panel since it arrives completely built-in ready.
