Smeg dishwashers independent test
(Translated)Show original

Third-party reviews

What we like about Smeg STL323BQLH

  • Efficient drying system with automatic door opening (Dry Assist+)
  • Spacious and adaptable interior with a flexible third cutlery basket (FlexiDuo)
  • Increased commercial height suitable for larger plates and tall dishes
  • Excellent water coverage and deep cleaning provided by the Planetarium wash system
  • Quiet operation with a dedicated low-noise program mode
  • Floor-projected status indicator light (Active Light) for integrated design tracking

What we don't like about Smeg STL323BQLH

  • High premium price point compared to standard dishwasher brands
  • Standard eco and normal wash programs take a relatively long time to complete
  • General brand feedback notes that customer service can be difficult to deal with for repairs
  • Integrated styling means a custom kitchen front panel must be sourced separately

Verdict

The Smeg STL323BQLH is an 86 cm maxi-height, fully integrated 60 cm dishwasher featuring a 14 place setting capacity, an Inverter 2.0 motor, and a patented Planetarium Wash System that rotates at 65 RPM for complete water coverage. Key advantages include an energy-efficient Class B rating consuming 64 kWh per 100 cycles, a low 42 dB operating noise level, a flexible FlexiDuo third cutlery tray, and a Dry Assist+ automatic door-opening system that enhances drying efficiency. However, its oversized 85.8 cm height requires non-standard tall cabinet niches, and the eco-program features a lengthy cycle duration of 4 hours and 25 minutes.
