Dispenser Assembly
The dispenser assembly provides automatic
dispensing of detergent, bleach, and fabric softener
as long as the user
fi lls the compartments prior to
starting the washer.
The products added to the dispenser are diluted
with water before they are dispensed into the wash
tub. This is accomplished by a water diverter that
sprays a controlled jet of water into the proper
compartment at the correct time. The water diverter
movement is provided by a motor-driven cam
located on the dispenser tank. The diverter motor
and water valve are operated by the control board.
At the start of a cycle, after the wake-up routine
is completed, the dispenser moves into the proper
position before
fi ll takes place.
