ABSTRACT:
A method to wash varying clothes load sizes with the same level of water is provided for a washer having a controller. A clothes load size setting signal is received in the controller. A mechanical duty cycle is set through the controller as a function of the clothes load size setting signal. A high-concentration wash step may be performed where a wash basket of the washer is spun at certain speeds while a highly concentrated wash bath solution is sprayed, extracted, and re-sprayed over the clothes load. On the completion of this high-concentration wash step, the washer is filled to a common water level regardless of the clothes load size setting signal. The clothes load is then processed through a wash cycle until completed.
