RESETTING TO FACTORY DEFAULTS:
To reset the electronic controller to its factory default for
all settings (time, hardness, etc.):
1.
Press the SELECT button and hold it until the display
changes twice to show “CODE” and the flashing model
code.
2.
Press the UP (
È
) button (a few times, if necessary) to
display a flashing “SoS”.
3.
Press the SELECT button, and the electronic controller
will restart.
4.
Set the present time, hardness, etc., as described on
pages 11 & 12.

This check verifies proper operation of the valve motor,
brine tank fill, brine draw, regeneration flow rates, and
other controller functions. Always make the initial checks,
and the manual initiated diagnostics.
NOTE:
The electronic control display must show a steady
time (not flashing).
1
. Press the RECHARGE button and hold in for 3 sec-
onds. “RECHARGE NOW” begins to flash as the sof-
tener enters the fill cycle of regeneration. Remove the
brinewell cover and, using a flashlight, observe fill
water entering the tank.
If water does not enter the tank, look for an obstructed
nozzle, venturi, fill flow plug, brine tubing, or brine
valve riser pipe.
2
. After observing fill, press the RECHARGE button to
move the softener into brining. A slow flow of water to
the drain will begin. Verify brine draw from the brine
tank by shining a flashlight into the brinewell and
observing a noticeable drop in the liquid level.
NOTE:
Be sure water is in contact with the salt, and not
separated by a salt bridge.
If the water softener does not draw brine, check for
(most likely to least likely):
=
Dirty or plugged nozzle and venturi.
=
Nozzle and venturi not seated on the gasket, or
gasket deformed.
=
Restriction in valve drain, causing a back-pressure
(bends, kinks, elevated too high, etc.).
=
Obstruction in brine valve or brine tubing
=
Inner valve failure (obstructed outlet disc, wave
washer deformed, etc.)
NOTE:
If water system pressure is low, an elevated drain
hose may cause back pressure, stopping brine draw.
3
. Again, press the RECHARGE button to move the sof-
tener into backwash. Look for a fast flow of water from
the drain hose.
An obstructed flow indicates
a plugged top distributor,
backwash flow plug, or drain
hose.
4
. Press the RECHARGE but-
ton to move the softener into
fast rinse. Again look for a
fast drain flow. Allow the
softener to rinse for a few
minutes to flush out any
brine that may remain in the
resin tank from the brining
cycle test.
5
. To return the softener to
service, press the
RECHARGE button.
