Single Rack Wash TM
The Single Rack Wash TM bypasses the lower spray
arm, directing the water fl ow only to the upper
rack. A plastic-covered steel ball, released by a wax
motor-controlled magnet, is forced by the water
fl ow to block the venturi for the lower spray arm.
Cleaning power is directed to the top basket ONLY
through the middle and upper spray arms. In Single
Rack Wash
TM , the tub fi lls with approximately 0.1 to
0.2 gals. less than a normal wash cycle.
Normal Wash Cycle: The pump fi lls with water
to the level indicated. The magnet on the end of
the wax motor holds the ball out of the water fl ow
path. The impeller spins counterclockwise to a high
velocity. Water fl owing from the impeller outward,
fi lls all chambers.

Single Rack Wash TM Cycle: The pump fi lls with water
to the level indicated. At the same time, the wax
motor energizes and pulls the magnet away. This
releases the ball from its position at the bottom of
the guide rail.
The impeller spins counterclockwise to a high
velocity. The water fl ows from the impeller and
carries the ball up the guide rail. The ball wedges
into the low-arm channel restricting the fl ow from
the lower spray arm. The water fl ow is now diverted
to only the upper and middle spray arms.
