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 the flashing model code.
2. Press the UP button (a few times, if necessary)
to display a flashing "SoS".
3. Press the SELECT button, and the electronic con-
troller will restart.
4. Set the present time, hardness, etc., as described
on pages 12-14.
MANUAL ADVANCE RECHARGE CHECK
This check verifies proper operation of the valve
motor, brine tank fill, brine draw, recharge 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). If an error code
shows, first press the SELECT button to enter
the diagnostic display.
1. Press the RECHARGE button and hold in for 3
seconds. RECHARGE begins to flash as the
softener's valve advances from the service to fill
position. 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's valve into the brine position. 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. This may take
15 to 20 minutes.
NOTE: Be sure water is in contact with the salt, and
not separated by a salt bridge (See "Breaking
A Salt Bridge" section).
If the water softener does not draw brine, check for
(most likely to least likely):
= Dirty or plugged nozzle and venturi, see
"Cleaning the Nozzle and Venturi" section.
= Nozzle and venturi not seated on the gasket, or
gasket deformed.
= Valve seals leaking (See Troubleshooting).
= Restriction in valve drain, causing a back-pressure
(bends, kinks, elevated too high, etc.). See
"Install Valve Drain Hose" section.
= Obstruction in brine valve or brine tubing.
NOTE: If water system pressure is low, a too-long or
elevated drain hose may cause back
pressure, stopping brine draw. Avoid drain
hose runs longer than 30 feet. Avoid elevat-
ing the hose more than 8 feet above the floor.
3. Press the RECHARGE button to move the
softener's valve into the backwash position. Look
for a fast flow of water from the drain hose. Check
that the drain can adequately handle the flow and
volume.
An obstructed flow indicates a plugged top
distributor, backwash flow plug, or drain hose.
4. Press the RECHARGE button to move the soften-
er's valve into the fast rinse position. 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's valve to the service posi-
tion, press the RECHARGE button.
