Flow rates for washing machines are expressed on the water rating label by the average total water consumption.
The most water efficient washing machines have at least a 5 star WELS rating (55 litres per wash. Load capacity 8kg)
Washing machines are tested for:
• average total water consumption
• rinse performance
• severity of wash
• soil removal
• wash of a normally soiled cotton load (at the rated load capacity of the machine)
• water efficiency rating (based on total water consumption and rated capacity)
• water extraction.
