What we like about Siemens SN23HI02KE

  • Whisper-quiet operation at 42dB
  • Smart features and convenient remote control via the Home Connect app
  • Significantly faster washing cycles with the varioSpeed Plus option
  • Flexible loading and unloading with the varioFlex basket system
  • Generous 13 place settings capacity

What we don't like about Siemens SN23HI02KE

  • Dishes and plastics can occasionally come out damp, requiring manual towel drying
  • The standard Eco mode cycle takes a long time to complete (around 4.5 hours)
  • The primary wash program sometimes struggles to completely remove stubborn, baked-on food from pots and pans
  • Energy efficiency class is only rated D
  • Lacks a dedicated third cutlery drawer, relying instead on a traditional cutlery basket

Verdict

The Siemens SN23HI02KE iQ300 is a 60 cm freestanding dishwasher with capacity for 13 place settings, an iQdrive motor, and quiet 42 dB operation. It offers six programmes, four special options, 9 litres of water use per Eco cycle, and a Class D rating at 84 kWh per 100 cycles. Benefits include Home Connect remote control, flexible varioFlex baskets, and varioSpeed Plus for faster washing and drying. Drawbacks are the middling Class D efficiency, an Eco cycle lasting around four and a half hours, and a conventional cutlery basket rather than a third upper tray.
