A. TROUBLESHOOTING
AUTOMATIC ELECTRONIC DIAGNOSTICS
The faceplate timer (PWA) computer has a self-
diagnostic function for the electrical system, except
for input power and water meter. The computer
monitors electronic components _ _r-r-
and circuits for correct opera-
tion. If a malfunction occurs, an 5.
error code appears in the face-
f
plate 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 SELECTbut-
ton. SELECT remains operational so the service per-
son can make the MANUAL INITIATED ELEC-
TRONIC DIAGNOSTICS (below) to further isolate
the defect, and check the water meter.

You will see one of the following displays. All of the
displays show what position the valve is in, if the
turbine is operating, and the position switch open or
closed status.

POSITION SWITCH STATUS: With the valve in ser-
vice, or any of the recharge cycles, the switch indica-
tor will show open -.',--. While the valve is rotating
from 1 position to another, the indicator will show
the switch closed --,_. A defect is probable if indica-
tions vary from this pattern.
WATER METER TURBINE: With soft water in use,
the turbine flow rate display continually repeats a
000 to 140 count for each gallon of water passing
through the turbine. The display will remain a
steady...000 if soft water 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 of the
sensor. You should get a reading in the display. If
you get a reading, unhook the in and out plumbing
and check the turbine for binding.
