    Abstract: Methods and apparatuses for washing fabric loads without water or using water only as a co-solvent are disclosed. One method of non-aqueous clothes washing includes the steps of disposing clothing in a wash container, delivering a wash liquor to the fabric load, the wash liquor comprising a substantially non-reactive, non-aqueous, non-oleophilic, apolar working fluid and at least one washing additive, applying mechanical energy to the clothing and wash liquor for a sufficient amount of time to provide fabric cleaning and, thereafter, substantially removing the wash liquor from the fabric load. The working fluid may be selected from the group consisting of perfluorocarbons, hydrofluoroethers, fluorinated hydrocarbons and fluoroinerts.

    Abstract: A method of determining an imbalance condition in a horizontal axis washing machine comprises several steps, including establishing a speed profile for the washing machine, having at least three increasing speed steps, operating a motor to rotate the washing machine drum sequentially through the three speed steps, measuring the power output of the motor at each speed step, calculating an average power output by averaging the power output at the first and second speed steps, calculating the difference between the power output at the third step and the average power output, comparing the difference to a predetermined threshold difference value, and sending a signal indicative of an imbalance condition if the difference exceeds the threshold difference value.
