A. TROUBLESHOOTING
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, and the manual initiated diag­
nostics.
Notes:
The faceplate display must show a steady time (not
flashing). If an error code shows, first press the SE­
LECT button to enter the diagnostic display.
Press the ON/OFF-HOLD button and hold in for
3 seconds. ^RECHARGE and Fill begin to flash
(or clean backwash begins, if set) as the softener
enters the fill cycle of regeneration. When FILL is
on steady, remove the brine well cover and, using
a flashlight, observe fill water entering the tank.
*Note:
If the CLEAN feature is set to ON, a cleaning back­
wash (CLEAN and Bkwsh or Rinse flashes in the dis­
play, along with the minutes of the clean cycle re­
maining), precedes the recharge.
a. If water does not enter the tank, look for an ob­
structed nozzle, venturi, fill flow plug, brine tubing,
or brine valve riser pipe.
CYCLE FLOW RATES (GALLONS PER MIN.)
FILL (flow to salt storage tank) 0.3 (1.1 liters)
BRINING \ .16 (.61 liters)
BRINE RINSE { .12 (.45 liters)
BACKWASH f (flow to dram)
2.0 (7.6 liters)
FAST RINSE ) 2.0 (7.6 liters)
After observing fill, press the ON/OFF-HOLD
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 a salt bridge is not preventing water with
salt contact.
a. 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.
Again press ON/OFF-HOLD to move the soft­
ener into backwash. Look for a fast flow of water
from the drain hose.
a. An obstructed flow indicates a plugged top dis­
tributor, backwash flow plug, or drain hose.
Press ON/OFF-HOLD 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.
To return the softener to service, press ON/ OFF­
HOLD.
