Position the door at a 30- to 45-degree angle. Fill
the reservoir with a liquid automatic dishwasher
detergent until the detergent reaches the threads
of the reservoir access. The dispenser tank holds
approximately 45 ounces of liquid dishwasher
detergent (about 1 to 2 months' supply).
Place the cap on the reservoir access threads, push
down, and then turn clockwise until the cap is tight.
To remove the detergent reservoir:
Note: Removing the reservoir access collar causes
structural damage to the collar. It must be replaced
with a new part (Part # WD35X10059).
Remove the outer door panel. (See
Outer Door
Panel
.) Insert a small, fl at blade screwdriver into the
slot in the side of the retaining collar and push the
screwdriver handle counterclockwise while turning
the reservoir access collar counterclockwise a
quarter turn. Remove the retaining collar. Unplug the
tube from the reservoir outlet and disconnect the
sensor from the control module.
Detergent Level Sensor
The SmartDispense detergent level sensor consists
of a single-level detection continuity sensor and
includes the following components:
• A grommet seal
• A
LOW DETERGENT LED indicator light
• A wire harness
When the detergent in the reservoir drops below
the continuity sensor, a signal is sent to the control
board, and the LOW DETERGENT LED indicator light
is turned on. The light indicates 3 to 7 wash cycles
are left before the detergent reservoir is completely
empty.
Note: The LOW DETERGENT LED may look like it
is illuminated when in fact it is not. An illuminated
indicator shines bright red.
Note: If the SmartDispense system is not being
used, the LOW DETERGENT light can be turned off
(or on) by pressing the ADDED HEAT button 5 times
within 3 seconds. There are 3 audible beeps when
the light goes off.
The sensor is similar to the type used in several
automotive applications, such as the windshield
wiper fl uid reservoir.

The control takes a reading of the detergent level at
power-up (when power is restored from an outage)
and each time the door is closed and latched.
The control outputs a pulsing 5-VDC analog signal
to the sensor and monitors the return voltage.
Changes in the quantity of detergent in the tank
change the amount of current drawn by the sensor.
Note: The dispenser tank comes as an assembly.
It includes the sensor with wire harness, gasket,
and retaining collar. The complete assembly part
number is WD35X10058.
