SECTION 5 SERVICE TECH. INFORMATION
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
and circuits for correct opera­
tion. If a malfunction occurs, an
error code appears in the face­
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 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.

If you don't get a reading in the display, with faucet
open, puh 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.

POSITION switch operation. If the letter ap­
pears, the switch is closed. If the dash shows, the
switch is open.
Use the RECHARGE button to manually ad­
vance the valve into each cycle and check correct
switch operation.
