Service: Manually Advance Regeneration Check
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
electronic diagnostics.
NOTE: The face plate display must show a steady time (not flashing).
Press the TOUCH or HOLD button and hold 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, brine
tubing, or brine valve riser pipe.
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.
NOTE: Be sure a salt bridge is not preventing water with salt contact.
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 & disc, wave washer, etc.).
NOTE: If water system pressure is low, an elevated drain hose may cause back pressure, stopping
brine draw.
Again, press the TOUCH or 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.
Press TOUCH or HOLD 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.
To return the water softening system to service, press TOUCH or HOLD. 5
