Service Tech Information
FIG. 62
The faceplate timer (PWA) computer has a self-diag-
nostic function for the electrical system, except for input
power and water meter. The computer monitors elec-
tronic components and circuits for correct operation. 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 button.
SELECT remains operational so the service person can
make the MANUAL INITIATED ELECTRONIC DIAG-
NOSTICS (below) to further isolate the defect, and
check the water meter.
PROCEDURE FOR REMOVING ERROR CODE
FROM FACEPLATE:
• Unplug transformer from outlet.
• Correct defect
• Plug in transformer.
• Wait for 8 minutes.
The error code will return if the defect was not corrected.
MANUAL INITIATED ELECTRONICS DIAGNOSTICS:
1. To enter diagnostics, press the SELECT button once
to go to the Main Menu. Move the black bar to
Service Mode and press Select. Move black bar to
Diagnostics and press Select.
You will see the display, showing valve cycle position,
position switch status (open or closed), and turbine
operation.
TURBINE OPERATION: If no water is flowing through
the softener, the turbine indicator displays 3 zeros.
When water is flowing, a 000 to 140 count repeats for
each gallon of water passing through the turbine. To
check for positive operation of the turbine if zeros are
shown, open a nearby soft water faucet and observe
the turbine count. If you don't get a reading in the dis-
play, with faucet 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.
