The energy consumption of a clothes washer is measured under conditions specified in an Australian Standard. Over a year, it is assumed that the clothes washer is used 7 times per week at rated capacity on a warm wash (warm CEC in red). A value for a cold wash energy of 7 times per week is also shown on the label (cold CEC in blue). The clothes washer is labelled on the "normal" or "regular" program (program specified for a normally soiled cotton load). The energy consumption of a clothes washer includes both electrical energy for motors and pumps and the energy embodied in any imported hot water or electrical energy used to heat the water internally. The majority of energy for a clothes washer is to heat water on a warm wash.
The measure of energy service for a clothes washer is rated load capacity. This is the value declared by the manufacturer and defines the test load used in the Australian Standard.
To be eligible for an energy label, a clothes washer must be able to meet a minimum level of wash performance, a minimum level of spinning performance and a must not exceed the "wear and tear" limits that are defined in the Australian Standard.
The Base Energy Consumption defines the "1 star" line for particular products. An additional star is awarded when the CEC of the model is reduced by a defined percentage from the BEC. The energy reduction per star is 27% for clothes washers. For example, a model that had a CEC that was 0.73 of the BEC or less would achieve 2 stars. Similar, a CEC of 0.533 (0.73 x 0.73) of the BEC or less would achieve 3 stars and so on.
For clothes washers, front and top loading models are rated on the same basis. The warm wash energy consumption and a component of residual moisture (spin performance) is used to define the star rating in comparison with the BEC. Therefore a model that has a good spin performance may get a marginally higher star rating than a model of the same capacity and CEC with a poor spin performance.
The detailed star rating equations are contained in the document 
"Equations for Appliance Star Ratings".
There is an overview of how star ratings are calculated for other products on this site.
