The faceplate timer (PWA) computer has a self-diagnostic
function for the electrical system, except put power and
water meter. The computer monitors electronic components
and circuits for correct operation. If a malfunction occurs, an
error code appears in the faceplate display.
The chart below shows the error codes that could appear,
and the possible problems for each code.

CODE
Err1, Err3, Err4
Err5
POSSIBLE PROBLEM
MOST LIKELY _ _,_
wiring harness connections at switch and faceplate not connected / position switch inoperable / motor inoperable
faceplate timer (PWA)
LESS LIKELY
While an error code appears in the display, all faceplate
buttons are inoperable except the SELECT button. SELECT
remains operational so the service person can make the
MANUAL INITIATED ELECTRONIC DIAGNOSTICS (below)
to further isolate the problem, and check the water meter.
PROCEDURE FOR REMOVING ERROR CODE
FROM FACEPLATE:
1. • Unplug transformer from outlet.
• Plug in transformer.
• Wait for 8 minutes.
2. • Unplug transformer from outlet.
• Correct problem.
• Plug in transformer.
• Wait for 8 minutes.
The error code will return ifthe problem was not corrected.
MANUAL INITIATED ELECTRONICS DIAGNOSTICS:
To enter diagnostics, press the SELECT button until 000 - -
shows in the display. See Fig. 48.
TURBINE OPERATION: If no water is flowing through the
softener, the turbine indicator displays three zeros. When
water is flowing, the flow bar scrolls across the display, and
a 000 to 199 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 and flow bar. If you don't get
a reading in the display, 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 plumb-
ing and check the turbine for binding.
POSITION SWITCH STATUS: With the valve in service, or
any of the recharge cycles, the switch indicator will show
open, while the valve is rotating from one position to anoth-
er, the indicator will show the switch closed. A defect is
probable if indications vary from this pattern.
