WIRING SCHEMATIC
FIG. 41
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 diagnos-
tics.
NOTE:
The electronic control display must show a
steady time (not flashing).
1
. Press the RECHARGE button and hold in for 3
seconds. “RECHARGE NOW” begins to flash as
the softener 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 tub-
ing, 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-pres-
sure (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, stop-
ping brine draw.
3
. Again, press the RECHARGE button to move the
softener into backwash. Look for a fast flow of
water from the drain hose.
An obstructed flow indicates a plugged top distribu-
tor, backwash flow plug, or drain hose.
4
. Press the RECHARGE button 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.
