1. Unplug the Central Water Whole Home Filtration
System’s transformer from electrical power.
2. Remove the top cover to expose the valve.
3. Unplug the wiring connections from the back of the
old Electronic Control Board (See Figure 2).
4. Carefully remove the old board by unsnapping it from
its retainer tabs.
5. Carefully snap the new Electronic Control Board into
the retainer tabs.
6. Reconnect the wiring to the new board (See Figure
2).
7. Plug the transformer into the electrical outlet. A
model code and a test number (example: J1.4) briefly
appear in the faceplate display. Then, 12:00 PM and
the words “PRESENT TIME" begin to flash.
NOTE: If “- - - -” shows in the display, press the
UP
or
DOWN button until “dF 1” shows in the
display. Then, press the ENTER button to set,
and change to the flashing “SET TIME" display.
8. Press the
UP or DOWN buttons to set the
present time. Up moves the display ahead; down
sets the time back. Be sure AM or PM is correct.
NOTE: Press buttons and quickly release to slowly
advance the display. Hold the buttons down for
fast advance.
9. Press the ENTER button a few times, until the time
appears on the display, but is not flashing.
10. For information about programming additional
features of the Central Whole Home Water Filtration
System, consult your owner’s manual.
11. If the valve is not in Service position, press the
CLEAN button and hold for 3 seconds to start a
Clean Rinse cycle. The display will flash
“RECHARGE NOW.” In 20 minutes the start up
Clean Rinse cycle will be complete and the valve
and electronic control board will be properly oriented
together. Subsequent Clean Rinse cycles will be for
3 minutes.
If you have questions about installation, call the
Kenmore Water Line at 1-800-426-9345, Monday -
Friday, 7 am to 8 pm, CST.
IMPORTANT: BE SURE THE VALVE CAM INDICATES
“SERVICE” POSITION (See Figure 1) WHEN REPLACING THE
ELECTRONIC CONTROL BOARD (PWA), TO ASSURE BOTH
VALVE AND PWA ARE ORIENTED, OR TIMED, TO THE SAME
CYCLE. If the valve is not in Service position, see step 11
below.
NOTE: When installing the electronic control board (PWA) on
the underside of the top cover, use care not to twist the circuit
board, or force it onto the mounting pegs. Twisting could
damage the printed circuits, or break the display glass.
