5A. 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 DIAGNOSTICS.
NOTE:
The face plate display must show a steady
time (not flashing).
1 . Press the ON/OFFĆHOLD button and hold in
for 3 seconds. RECHARGE NOWbegins 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.
A . If it does not enter the tank, look for an obĆ
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 .35 (1.3 liters)
BRINE RINSE .22 (0.8 liters)
BACKWASH (flow to drain) 1.8 (6.8 liters)
FAST RINSE 1.8 (6.8 liters)
2 . After observing fill, press the ON/OFFĆHOLD
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.
3 . Again press ON/OFFĆHOLD to move the
softener into backwash. Look for a fast flow of
water from the drain hose.
A . An obstructed flow indicates a plugged backĆ
wash flow plug, drain hose, filter screen, or top
distributor.
CAUTION:
Do Not remove the top distributor
from the resin tank. Loss of water softening
resin will occur. See bottom of page 28.
4 . Press ON/OFFĆHOLD 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
ON/OFFĆHOLD.
