We test on a normal, cold wash. When this doesn't exist on a machine, we use the closest approximation to a normal, cold wash. This is because your feedback tells us this is what you mostly use. Because of this selection, you'll sometimes see differences between what the energy and water labels say on the machine and our results. This is because manufacturers try to get as good an energy and water label as possible, as the more stars they have, the better the chance a consumer will buy their product. Unfortunately, often this means the program the manufacturer selects is not what consumers will choose at home.
