SECTION5 SERVICE TECH. INFORMATION
A. TROUBLESHOOTING
AUTOMATIC ELECTRONIC DIAGNOSTICS
The faceplate timer (PWA) com-
puter has a self-diagnostic func-
tion for the electrical system, ex- E r F _ _
cept for input power and water
meter. The computer monitors electronic compo-
nents and circuits for correct operation. If a malfunc-
tion 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 INITIATED ELEC-
TRONIC DIAGNOSTICS (below) to further isolate
the defect, and check the water meter.

gallon of water passing through the meter.
If you don't get a reading in the display with faucet
open, pull the sensor from the vane 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.
B. The letter (P) and dashes indicate POSITION
switch operation. If the letter appears, the
switch is closed. If the dashes show, the switch
is open.
Use the RECHARGE button to manually ad-
vance the vane into each cycle and check correct
switch operation.
