ABSTRACT:
Applicant discloses a front load washing machine with the wash/run cycles modified to include a single, longer than normal wash cycle which also uses more water than normal. A single, longer than normal rinse cycle is provided, which also uses more water than normal. Typically the spin cycle may be run longer than normal. The effect of running only a single wash and a single rinse cycle, even though more water than normal is used in each of those cycles is to save water over the multiple “drain and fill” cycles.
