a) The deviation between the displayed water consumption and the measured value shall not be greater than 20%;

b) The deviation between the displayed electricity consumption and the measured value shall not be greater than 20%;

c) The local unit or remote unit can synchronously check the statistical information of water and electricity consumption of the intelligent washing machine according to different washing cycle dimensions.

Note: Washing cycle dimension can include washing times, days, weeks, months, years, cumulative, etc.

4.3.6 Self-cleaning function

Intelligent washing machine shall be equipped with the function to keep itself clean or conduct self-cleaning automatically and avoid secondary pollution, and shall meet at least one of the following requirements:
