AUTOMATIC ELECTRONIC DIAGNOSTICS
The faceplate computer has a self--diagnostic func-
tion for the electrical system (except input power and
water meter). The computer monitors electronic
components and circuits for correct
operation. If a malfunction occurs, an
error code appears in the faceplate
display.
The chart below shows the error codes that could
appear, and the possible defects for each code.
While an error code appears in the display, all face-
plate buttons are inoperable except the SELECT
button. SELECT remains operational so the service
person can make the MANUAL INI-
TIATED ELECTRONIC DIAGNOS-
TICS, below, to further isolate the de-
fect, and to check the water meter.

TROUBLESHOOTING,
MANUAL INITIATED ELECTRONIC DIAGNOSTICS
1.
To enter diagnostics,
press the SELECT/EXIT
(
¿
) to enter the menu. This
screen contains informa-
tion that can be used to
troubleshoot errors. Use
the (
-
) and (
¯
) buttons to
scroll through all lines on
this screen.
The first line shows time of day and error code.
Second line is
Pos:
which shows what position the
valve is in. Example: Service, Fill, Brining and Brine
Rinse, Backwash and Fast Rinse. The clock to the
right counts backward the time for each of the posi-
tions to be completed.
The next line is
Req Pos:
which is for requested
position, or what position the valve is travelling to.
Next line displays
Motor:
, either on or off, and
Sw:
either open or closed.
Next is
Trbn:
and
Gals:
which indicate water meter
operation as follows.
000 (steady) = conditioned water not in use...no flow
through the meter.
--open a nearby CONDITIONED WATER faucet--
000 to 151 (continual) = repeats display for each gal-
lon of water passing through
the meter.
If you don’tget a reading in the display, with a faucet
open, pull the sensor housing from the valve outlet
port. Pass a small magnet back and forth in front of
the sensor. You should get a reading. If you
do get
a reading
, disconnect the outlet plumbing and
check the turbine for binding. If you
don’t get a
reading
, the sensor is probably defective
