Flow rates for dishwashers are expressed on the water rating label by the average total water consumption.
The most water efficient dishwashers have a 6 star WELS rating. (10 litres per wash. 15 place settings)
Dishwashers are tested for:
• average total water consumption
• wash of a soiled load (equal to the maximum number of place settings the machine can carry)
• washing and drying effectiveness.
