AUTOMATIC ELECTRONIC DIAGNOSTICS
This water softener has a self-diagnostic function for
the electrical system (except input power and/or water
meter). The water softener monitors electronic com-
ponents and circuits for correct operation. If a mal-
function occurs, an error code appears in the display.
While an error code appears in the display, all buttons
are inoperable except the SELECT button. SELECT
remains operational so the service person can perform
the Manual Advance Diagnostics, see below, to further
isolate the problem.
TO REMOVE AN ERROR CODE:
1. Unplug power supply from electrical outlet.
2. Correct problem.
3. Plug power supply back in.
4. Wait 8 minutes. The error code will return if the
problem was not corrected.
MANUALLY INITIATED ELECTRONIC
DIAGNOSTICS
1. To enter diagnostics, press the SELECT button and
hold for three seconds. The display will change to
show turbine count, valve cycle position, and posi-
tion switch status (open or closed).
Position Switch Indicator (Open)
TURBINE OPERATION: If no water is flowing through
the softener, the turbine indicator displays three zeros.
When water is flowing, a 000 to 140 count repeats for
each gallon (3.8 liters) 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 read-
ing in the display with faucet open, pull the sensor
housing from the valve outlet port (see Fig. 45). Pass

You should get a reading in the display. If you get a
reading, unhook the inlet and outlet plumbing and
check the turbine for binding.
POSITION SWITCH STATUS: With the valve in serv-
ice, or any of the recharge cycle positions, the position
switch indicator will show the switch open. While the
valve is rotating from one position to another, the posi-
tion switch indicator will show the switch closed.
There is likely a problem if indications vary from this
pattern.
OTHER INFORMATION: While in the diagnostics
screen, the following information is available and may
be beneficial for various reasons. This information is
retained by the electronic controller from the first time
electrical power is applied to the unit.
= Press and hold the
number of days this controller has had electrical
power applied.
= Press and hold the
number of regenerations initiated by this controller
since the model code number was entered.
NOTE: If the electronic controller is left in the diagnos-
tic display (or a flashing display when setting
times or hardness), the normal time of day dis-
play automatically returns if a button has not
been pressed for 4 minutes. To return to the
diagnostic display, repeat step 1, above.
