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 manual initiated diag-
nostics.
NOTE: The face plate display must show a steady
time (not flashing).
1. Press the TOUCH - HOLD button and KROG in for
3 seconds. RECHARGE NOW begins to flash as the
softener enters the fill cycle of regeneration. Re-
move the brinewell cover and, using a flashlight, ob-
serve fill water entering the brine tank.
 If water does not enter the tank, look for an ob-
structed nozzle, venturi, fill flow plug, brine tubing,
or brine valve riser pipe.

water to the drain will begin. Verify brine draw from
the brine tank by shining a flashlight into the brine-
well and observing a noticeable drop in the liquid
level.
NOTE: Be sure a salt bridge is not preventing water
with salt contact.
 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 the TOUCH - HOLD button to move
the softener 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 TOUCH - 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 brin-
ing cycle test.
5. To return the softener to service, press TOUCH
- HOLD.
