Verdict

The Zanussi ZDLN2521 is a 60cm fully integrated dishwasher with a 13-place setting capacity and an 'E' energy rating, making it a reliable choice for medium-sized households. Key characteristics include 6 wash programs (including an Eco 50°C and a fast 30-minute wash), an AutoSense sensor that optimizes water/energy usage, and an AirDry feature that automatically opens the door by 10cm for natural, efficient drying. Main pros are its quiet 47 dB noise operation, highly efficient 9.9L water consumption per cycle, and the highly flexible QuickLift upper basket that accommodates bulky items. However, it does have a few drawbacks, such as a longer standard cycle time (up to 227 minutes on Eco), reliance on a standard cutlery basket rather than an upper tray, and the absence of a half-load option for smaller washes.
