Third-party reviews

What we like about Smeg STL342CSL

  • Seamless total integrated built-in design blends perfectly with modern kitchen cabinets.
  • Excellent washing coverage provided by the dual rotating Orbital Wash System.
  • Fast and energy-efficient drying using the Dry Assist+ automatic door opening system.
  • Highly flexible interior organization with the customizable FlexiDuo third basket tray.
  • Convenient ultra-fast programs including a 27-minute express cycle for lightly soiled items.
  • Discrete operation due to a low noise level and an Active Light beam indicator projected onto the floor.
  • Smooth-sliding, adjustable door alignment achieved via the FlexiFit hinge system.

What we don't like about Smeg STL342CSL

  • High retail purchase price makes it a significant financial investment compared to standard models.
  • Brand customer support is widely criticized by users as unhelpful and difficult to deal with for post-purchase resolutions.
  • General user sentiment highlights frequent long-term quality and electronic durability concerns for the appliance brand.

Verdict

The SMEG STL342CSL is a 60 cm fully-integrated built-in dishwasher featuring a 13 place setting capacity, a 3-basket FlexiDuo layout, and an efficient C-class energy rating with a 9-liter water consumption rate per cycle. Operating at a quiet 44 dB noise level, its primary advantages include an Orbital wash system for even water distribution, 11 distinct wash programs—such as a 27-minute Express cycle and a 75°C Hygiene sterilization program—and the Dry Assist+ natural condenser system that automatically opens the door at the end of a cycle to maximize drying efficiency. However, a potential disadvantage is that it lacks smart connectivity features, and it comes completely hidden without a front kitchen panel included, requiring a custom cabinet door match.
