Verdict

The Bosch SMS4HTW03E is a freestanding 60 cm Series 4 dishwasher in white, offering a 13-place setting capacity and operating quietly at 46 dB. It features a heat exchanger drying system, 6 wash programs (including Eco 50°C, Auto 45-65°C, and Intensive 70°C), and 4 special options such as SpeedPerfect+, Half Load, and ExtraDry. Its main pros include smart Wi-Fi integration via the Home Connect app, a flexible Vario basket system with a height-adjustable Rackmatic top basket, a low water consumption of 9 liters per cycle, and robust AquaStop leak protection. On the downside, it has a modest energy efficiency rating of Class D (consuming 84 kWh per 100 cycles), its Eco program has a very long cycle duration of 4 hours and 30 minutes, and its standard drying capabilities can struggle with plastic tableware unless the ExtraDry option is manually activated.
