Water Hardness Test and Calibration
Test Water Hardness
The automatic liquid dishwashing detergent
dispenser (SmartDispense
TM ) dispenses the optimum
amount of detergent to clean the dishes. This
amount of detergent introduced during each cycle
is based on the soil level of the dishes and the
hardness of the water. Therefore, the correct water
hardness setting is very important for both optimum
cleaning of dishes and detergent usage.
Prior to the fi rst use, this dishwasher must be
calibrated for water hardness. This process requires
the use of a water hardness test strip (part #
WD01X10295). This part can by shipped by mail.
The 4 light green stripes will change color. The
harder the water, the more stripes will change from
green to red.
Water hardness should be tested following the
instructions on the test strip package shown above.
Note: If all stripes remain green after the test, the
outcome is "0 RED". The value to be entered into the
dishwasher is "1".
Convert the test reading according to the table
below.

Note: 1 grain per gallon = 17.1 parts per million.
SmartDispense TM Calibration
The calibration process will differ slightly depending
on whether the dishwasher is front mount control
(PDW8000 series) or top mount control (PDW9000
series).
Front Mount Control (PDW8900)
Dishwasher must be in standby mode. Close and
latch the door. Press normal wash to illuminate the
lights on the control panel.
Press Cookware pad and Delay Hours pad
together and hold for 3 seconds.
The current hardness setting will be shown on
the Time Remaining display.
Enter the value from the test strip using the
Cookware pad to increase the value or the
Normal Wash pad to decrease the value.
Press the Start/Reset pad to return the
dishwasher to normal operation. The last
displayed value will be saved as the water
hardness value.
Top Mount Control (PDW9700, PDW9900)
Dishwasher must be in standby mode. Press up
arrow to wake up control and illuminate the lights
on the control panel.

arrow pad to increase the value or the down
arrow pad to decrease the value.
Press the Start/Reset pad to return the
dishwasher to normal operation. The last
