What we like about Smeg DI4522

  • Whisper-quiet operation assisted by an Inverter motor and dedicated Silence program
  • Excellent cleaning efficiency enhanced by the SwingWash system to reach all corners
  • Effective natural drying because the Dry Assist function automatically pops the door open to release steam
  • Highly space-efficient 45cm slimline design ideal for smaller kitchens or flats
  • Flexible loading choices with a height-adjustable upper basket
  • Convenient fast washing provided by the Express 50-minute cycle

What we don't like about Smeg DI4522

  • Relatively expensive compared to similar slimline models on the market
  • Electronic controls can feel awkward or non-intuitive to navigate
  • Interior capacity is naturally limited due to its compact 9 place-setting layout
  • Aesthetic finish on newer iterations does not feel as premium as older Smeg units it replaces

Verdict

The SMEG DI4522 is a fully integrated slimline dishwasher measuring 44.6 cm wide, featuring a 9 place setting capacity, an Inverter 2.0 motor, and an operating noise level of 46 dB. It offers 6 wash programs, including an Express 50-minute cycle and an Eco mode, utilizing a Dry Assist automatic door-opening system for natural condenser drying alongside blue anti-drip inserts to improve drying efficiency. Key advantages include a space-saving design ideal for compact kitchens, an efficient SwingWash spray arm system, a delay start timer up to 3 hours, and robust flood protection via the Total AquaStop system. However, notable drawbacks include its low E energy efficiency rating on the updated A-G scale, a maximum delay timer constraint of only 3 hours, and the lack of a child lock mechanism.
