This check verifies proper operation of the valve
motor, brine tank fill, brine draw, regeneration
flow rates and other controller functions. First,
make the initial checks and the Manually Initiated
Electronics Diagnostics.
NOTE: The control display must show a steady
time (not flashing).
1. Press the TOUCH OR HOLD button and hold in
for three seconds. RECHARGE NOW begins to
flash as the water softening system enters the
fill cycle of regeneration. Remove the brinewell
cover and, using a flashlight, observe fill water
entering the brine tank. If water does not enter
the tank, look for an obstructed nozzle, venturi,
fill flow plug or brine tubing. See Care and
cleaning of the water softening system section.
2. After observing fill, press the TOUCH OR HOLD
button to move the water softening system
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 over an extended period of time.
NOTE: Be sure a salt bridge is not preventing
water from contacting salt. See Care and
cleaning of the water softening system section.
If the water softening system does not draw
brine, check:
■
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 and
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 the TOUCH OR HOLD button
to move the water softening system into
backwash. Look for a fast flow of water from
the drain hose. A slow flow indicates a plugged
top distributor, backwash flow plug or drain
hose.
4. Press the TOUCH OR HOLD button to move the
water softening system into fast rinse. Again
look for a fast drain flow. Allow the water
softening system 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 water softening system to
service, press the TOUCH OR HOLD button.
