Position Switch Status; Timer Pwa Replacement - Kenmore IntelliSoft 420 Series Owner's Manual

POSITION SWITCH STATUS: With the valve in service,
or any of the recharge cycles, the switch indicator will
show open, while the valve is rotating from one position
to another, the indicator will show the switch closed. A
defect is probable if indications vary from this pattern.
NOTE: If the faceplate is left in a diagnostic display
(or a flashing display when setting times or hard-
ness), present time automatically returns if a button
is not pressed within 4 minutes. To return to the
diagnostic display, repeat step 1.
2. Press the RECHARGE button to advance the valve
to each position and observe the switch and position
indicators to verify component operation, or to possi-
bly isolate a defect.

ed.

SELECT button until the normal operating display
shows.
To change the number: Press the UP or DOWN
button until the correct model code (HF46) shows.

TIMER PWA REPLACEMENT
Be sure the valve is in service position when replac-
ing the timer PWA (observe valve cycle indicator). If
after installing and programming the replacement timer
PWA, the valve is not in service position, do the following
to assure correct cycle orientation, or timing, between the
faceplate and valve.
Use the MANUAL ADVANCE procedures with the
RECHARGE NOW button, advance through the recharge
cycles until the valve stops in service position, and
RECHARGE no longer flashes in the display.
NOTE: The valve motor may automatically drive through
several valve positions while searching for service. If an
error code occurs, unplug the transformer, then plug in
again.
