Quick Clean Up
Use this cycle for pre-rinsed or lightly-soiled loads. The cycle automatically adds a fill and brief pre-
wash, purging cold water from the hot water line improves washing results, without adding time for
water heating periods. Initial display time: 48 min.
Rinse Only
Use this rinse cycle for rinsing dishes, glasses and silverware that will not be washed right away.
Initial display time: 10 min.
AUTOMATIC PURGE FILTRATION (APF)
The soil sensor (pressure switch) monitors water pressure at the output of the drain pump. The
pressure is created by the concentration of soils trapped against the accumulator screen. As pressure
builds, the water level in the drain tube loop is pushed higher. When the water level in the tube rises
10 inches (the equivalent of 10 inches of water column pressure) the soil sensor switch closes indicat-
ing to the electronic control that high soil levels are present.
The electronic control invokes the APF feature in specific intervals of the Pre-Wash and Wash peri-
ods. Up to five intervals are available to enable APF events. As many as three APF events may occur
in any one of these intervals, however, APF events will be spaced no less than one minute apart.
APF operates for a total of 10 seconds while the wash motor continues to operate. The accumulator
screen will be cleaned from jets on the underside of the lower spray arm as the washing action contin-
ues.
During the first five seconds, the drain motor turns on and the fill valve is activated. This purges the
soiled water from the accumulator and begins to add fresh water. For the remaining five seconds, the
drain pump is turned off, but the fill valve remains activated to bring the wash water back to the proper
level.
