What we like about NEFF S257ECX21E N70

  • Excellent cleaning results, especially with the intensive Chef 70°C program for stubborn stains
  • Extremely quiet operation at a low 42 dB noise level
  • Useful TimeLight feature that projects the remaining cycle time onto the kitchen floor
  • Open Dry automatic door opening system that improves air drying efficiency
  • Flexible Flex 2 basket layout with an adjustable RackMatic upper basket and a dedicated cutlery drawer
  • Convenient Home Connect smart app integration for remote monitoring and control

What we don't like about NEFF S257ECX21E N70

  • Long cycle duration when running the energy-saving Eco program
  • A cutlery drawer layout that some users find fiddly or tedious to pack compared to an upright basket
  • Lower energy efficiency grade (Class D under newer EU rating standards)

Verdict

The NEFF S257ECX21E N70 is a fully integrated, 60 cm XXL built-in dishwasher offering a spacious 14 place setting capacity and an operating volume of 42 dB. Key characteristics include 8 wash programs—highlighted by the high-temperature Chef 70°C cycle for stubborn stains—and 4 special functions like VarioSpeed Plus and IntensiveZone. Notable pros feature the Open Dry automatic door-opening system for enhanced drying efficiency, TimeLight floor projection for program status, a highly adjustable Flex 1 basket system with an extra drawer, and smart operation through Home Connect Wi-Fi integration. On the downside, the appliance carries a relatively modest D energy efficiency rating on the modern A-G scale, and its standard Eco wash cycle requires a lengthy 4 hours and 35 minutes to complete.
