Abstract: A dishwasher includes an independent presoak system which may be activated by a user of the dishwasher. The dishwasher presoak system utilizes a storage tank, supply tubes, and set of nozzles which are independent from components used in a washing cycle such that a presoak detergent is applied to items placed within a washing compartment of the dishwasher without being diluted by a standard wash cycle. As part of the presoak system, the dishwasher features a detection system which allows the user to select an automatic presoak operating state whereby the dishwasher utilizes a sensor to determine if items placed into the washing compartment are sufficiently dirty to need a presoak cycle prior to a washing cycle. The dishwasher further relies on a control system to analyze samples taken of the dirtiness levels of items placed within the washing compartment and determine whether a presoak option is necessary or suggested.

Abstract: A domestic dishwasher includes a wire rack that does not include any rolling elements that would otherwise allow the rack to roll between an extended position and a retracted position. Instead of rolling elements, the rack includes sliding surfaces that slide along corresponding surfaces inside the dishwasher and/or on a dishwasher door. The rack may be a lowermost rack.
