What we like about Sharp QW-NA1DF45EI

  • Large capacity accommodating 15 place settings
  • Quiet operation at 45 dB with QuietMode
  • Turbo Fan system ensures highly efficient drying performance
  • Flexible configuration with fully foldable racks and adjustable upper basket
  • Useful choice of wash programs including Eco 50°C and Express 50 min

What we don't like about Sharp QW-NA1DF45EI

  • Long cycle duration for the Eco wash program reaching nearly three hours
  • Unsatisfactory cleaning performance on heavily soiled items when using shorter rapid cycles
  • Potential stability issues where the bottom rack may tilt forward if front-loaded before the back
  • Known customer complaints regarding manufacturer warranty service responsiveness and engineer scheduling

Verdict

The SHARP QW-NA1DF45EI is a full-size, 60 cm freestanding stainless steel dishwasher designed with a generous 15 place setting capacity and a 3-basket system featuring an adjustable upper rack. Key specifications include 5 wash programs (Eco 50°C, Express 50min, Hygiene, Intensive 65°C, and Quick), a 45 dB noise rating, a 9-liter water consumption rate per eco cycle, an LED/graphic display with touch controls, a 24-hour delay timer, and a Microban antibacterial filter system paired with active turbo fan drying. Main advantages include its exceptionally spacious interior with flexible loading, highly efficient water usage, a very quiet operational profile, and dedicated hygiene options. On the downside, its lower 'E' energy efficiency rating under revised standards leads to a higher consumption of 97 kWh per 100 cycles, and some users note that very tall plates must be angled or carefully placed to avoid striking the spray arms.
