Troubleshooting
AUTOMATIC ELECTRONIC DIAGNOSTICS
The electronic controller has a self-diagnostic function for
the electrical system (except input power and water
meter). The computer monitors the electronic compo-
nents and circuits for correct operation. If a malfunction
occurs, an error code appears in the display.
The chart on the previous page shows the error codes
that could appear, and possible problems indicated by the
codes. While an error code is displayed, all timer buttons
are inoperable, except for the SELECT button. SELECT
remains operational so the service person can make use
of the Manually Initiated Electronic Diagnostics to further
isolate the defect, and check the water meter.
TO REMOVE AN ERROR CODE:
1
. Unplug the transformer.
2
. Correct the problem.
3
. Plug the transformer back in.
4
. Wait for at least 8 minutes while the electronic con-
troller operates the valve through an entire cycle. The
error code will return if the problem was not corrected.

MANUALLY INITIATED ELECTRONIC
DIAGNOSTICS
1
. To enter diagnostics, press and hold the SELECT but-
ton until “000 - -” appears in the display.
FIG. 33
2
. The first 3 digits indicate water meter operation as fol-
lows:
000 (steady) = Soft water not in use, and no flow
through the meter.
OPEN A NEARBY SOFT WATER FAUCET.
000 to 199 = Repeats for each gallon of water
passing through the meter.
NOTE:
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. If you get a reading in the display with
the magnet, unhook the in and out plumbing and
check the turbine for binding (See Figure 32).
3
. The last 2 digits in the display indicate position switch
operation as follows:
4
. Use the RECHARGE button to manually advance the
valve into each cycle and check correct switch operation.
5
. While in this diagnostic screen, the following informa-
tion is available and may be beneficial for various rea-
sons. This information is retained by the computer
from the first time electrical power is applied to the
electronic controller.
a
. Press the UP (
È
) button to display the number of days
this electronic control has had electrical power applied.
b
. Press the DOWN (
–
) button to display the number of
regenerations initiated by this electronic control
since the model code number was entered.
6
. Press the SELECT button and hold in for 3 seconds
until the model code (see table on page 3) shows in
the display. This code identifies the softener model. If
the wrong number shows, the softener will operate on
incorrect configuration data.
Correct Switch

Valve Cycle Status
– –
Valve in service, fill, brining,
backwash or fast rinse position.
–
P
Valve rotating from one position
to another.
7
. To change the code number - Press UP (
È
) or DOWN
(
–
) button until the correct code shows.
8
. To return to the present time display, press the
SELECT button.
If the model code was changed,
make all electronic controller settings.
NOTE:
If the electronic control is left in a diagnostic dis-
play (or a flashing display when setting times or
hardness), present time automatically returns if a
button is not pressed within 4 minutes.
