What does energy class A mean for a dishwasher?
Energy class A is the most efficient band on the current A-to-G EU dishwasher label. The classification is calculated from standardized Eco-program performance and is intended to compare machines at their rated capacity.
The label also reports energy per 100 Eco cycles, water per Eco cycle, rated place settings, Eco duration, and airborne-noise information. Compare all of these fields because two A-rated machines can differ in water use, capacity, noise, and cycle time.
Class A does not mean every program uses the Eco figure or that cleaning and drying are automatically superior. Quick, intensive, hygiene, and extra-dry options can consume more, while rack design and loading habits determine whether the rated efficiency is achieved in daily use.
How much energy and water does an A-rated dishwasher use?
An A-rated dishwasher commonly uses about 0.49–0.55 kWh and 9–10 L of water on its Eco cycle. At one cycle per day, that is roughly 180–200 kWh and 3,300–3,700 L per year, although actual consumption changes with programs, loading, inlet conditions, and maintenance.
Eco cycles reduce heating demand by running longer. Automatic, intensive, quick, hygiene, and extra-dry modes may use more energy or water, so compare the cycles expected in normal use rather than applying the label value to every wash.
Capacity changes the interpretation: most A-rated machines hold 14 settings. A full load can be efficient per item, while repeated partial loads, overcrowding, or rewashing can remove much of the saving.
