play changes twice to show "SET" and the flashing
model code.
2. Press the UP button (a few times, if necessary)
to display a flashing "SoS".

troller will restart.

MANUAL ADVANCE REGENERATION
CHECK
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 first, and perform the manually initi-
ated electronic diagnostics.
NOTE: The 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 for 3 sec-
onds. RECHARGE begins to flash as the soften-
er's valve advances from the service to fill position.
2. Remove the brinewell cover and, using a flashlight,
observe fill water entering the tank.
3. If water does not enter the tank, look for an
obstructed nozzle, venturi, fill flow plug, brine tub-
ing, or brine valve riser pipe.
4. 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.
5. If the softener does not draw brine:
= nozzle and/or venturi dirty
= nozzle and venturi not seated properly on gasket
= restricted drain (check drain fitting and hose)
= ineffective nozzle and venturi seal
= other inner valve problem (rotor seal, rotor &
disc, wave washer, etc.)
NOTE: If water system pressure is low, an elevated
drain hose may cause back pressure, stop-
ping brine draw.
6. Again press RECHARGE to move the softener into
backwash. Look for a fast flow of water from the
drain hose.
7. An obstructed flow indicates a plugged top distribu-
tor, backwash flow plug or drain hose.
8. Press RECHARGE 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.
9. To return the softener to service, press RECHARGE
once more.
