DIAGNOSTICS
The faceplate
timer
(PWA)
computer
has
a self-
diagnostic
function
for the electrical
system,
except
for input
power
and
water
me-
ter. The computer
monitors
elec-
tronic
components
and
circuits
for correct
operation.
If a mal-
function
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 but-
ton. SELECT remains
operational
so the service
per-
son
can
make
the MANUAL

to further
isolate
the defect,
and check the water
meter.

WATER
METER
TURBINE:
With soft water

continually
repeats
a
000 to 140 count
for each
gallon
of water
passing
through
the
turbine.
The

is not in use (open
a nearby
soft water
faucet
to check).
If you don't
get a reading
in the display,
with facuet
open,
pull
the sensor
from
the valve
outlet
port.
Pass a small
magnet
back and forth
in front
