Service Tech Information
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-
NOTE: The faceplate display must show a steady
time (not flashing). If an error code shows, first
press the SELECT button to enter the diagnostic
1. Press the REGENERATION button and hold in for 3
seconds. RECHARGE NOW begins to flash in the
display as the softener enters the fill cycle of regen-
eration. Remove the brinewell cover and, using a
flashlight, observe fill water entering the tank.
2. When FILL is on steady, 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.
FILL (flow to salt storage tank) 0.3 (1.1 liters)
BRINING (flow to drain) .15 (.57 liters)
BRINE RINSE (flow to drain) .1 (.38 liters)
MAX. BACKWASH (flow to drain) 2.0 (7.6 liters)
MAX. FAST RINSE (flow to drain) 2.0 (7.6 liters)
4. After observing fill, press the REGENERATION but-
ton 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 liq-
uid level.
NOTE: Be sure a salt bridge is not preventing
water with salt contact.
5. If the softener does not draw brine:
• nozzle and/or venturi dirty or defective
• nozzle and venturi not seated properly on gasket
• restricted drain (check drain fitting and hose)
• defective nozzle and venturi seal
• other inner valve defect (rotor seal, rotor & disc,
wave washer, etc.)
NOTE: If water system pressure is low, an elevated
drain hose may cause back pressure, stopping
brine draw.
6. Again press REGENERATION 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 distributor,
backwash flow plug or drain hose.
8. Press REGENERATION to move the softener into fast
rinse. Again look for a fast drain flow. Allow the soften-
er to rinse for a few minutes to flush out any brine that
may remain in the resin tank from the brining cycle
9. To return the softener to service, press REGENERA-
TION once more.
