The following conversion factors may be used to convert the water consumption on new EU energy labels from litres per cycle (L/cycle) into litres per year (L/year):
Dishwasher: multiply water consumption figure on EU energy label by 280 (to go from L/cycle to L/year).
Washing machines: multiply water consumption figure on EU energy label by 220 (to go from L/cycle to L/year).
This follows equivalent guidance for converting energy consumption (see KBCN1462).
