Verdict

The SMEG ST311CS is a 60 cm fully integrated built-in dishwasher offering a 13 place setting capacity, operating with an energy efficiency rating of Class C and consuming 12 liters of water and 73 kWh of electricity per 100 eco cycles. Main characteristics and pros include its electronic controls, 5 versatile wash programs (including Eco, Mix, and an intense 70°C Ultraclean cycle), a 3-6-9 hour delay timer, Single Acquastop flood protection, and a highly efficient Dry Assist system that automatically opens the door at the end of a cycle to optimize natural condenser drying. On the downside, it features a relatively high 51 dB(A) noise emission level (Class D) and lacks a third-level cutlery drawer, utilizing a standard lower-basket cutlery setup instead.
