Energy efficiency (10%)
If a machine has an “auto” cycle, we select it over the “normal” cycle. We do this because an auto or sensing cycle should be designed to give optimum results for every wash. We put each dishwasher through its paces at least twice and the scores are averaged.
To really test a dishwasher’s ability to clean, we carefully dirty each test load with a range of foods and let them dry for 15 to 18 hours. And we’ve added baked-on porridge to the foods we’ve always used (such as baby cereal, spinach, egg yolk, tomato juice, tea and butter). Each of the foods plays a crucial part in assessing how the dishwasher performs and they’re there to test things like filtration, spray-arm effectiveness, rinsing and automatic sensors.
