The wash pump starts
6 seconds before the fill/rinse

runs for 3 seconds to evacuate
air from wash pump before
the pumped final rinse begins.
Solid state timer control
prevents the rinse aid pump
from running after the
fill/rinse valve closes.
Note 2:
Solid state timer control
prevents detergent pump
from running longer than
time required to fill/refill
wash tank.
