Service Information
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 first, and perform the manually initiated elec- tronic diagnostics.
NOTE: The display must show a steady time (not flash- ing). If an error code shows, first press the SELECT button to enter the diagnostic display.
1. Press the REGENERATION button and hold in for 3 seconds. “RECHARGE”, “Serv” and “Fill” begin to flash in the display as the softener enters the fill cycle of regeneration.
2. When valve reaches “Fill” position, remove the brinewell cover and, using a flashlight, observe fill water entering the tank.
3. If water does not enter the tank, look for an obstructed nozzle, venturi, fill flow plug, brine tubing, or brine valve riser pipe.
4. After observing fill, press the REGENERATION 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 liq- uid level.
5. If the softener does not draw brine: = nozzle and/or venturi dirty
= nozzle and venturi not seated properly on gasket = restricted drain (check drain fitting and hose) = ineffective nozzle and venturi seal
= other inner valve problem (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.
6. Again press REGENERATION to move the softener into backwash. Look for a fast flow of water from the drain hose.
7. An obstructed flow indicates a plugged top distribu- tor, backwash flow plug or drain hose.
8. Press REGENERATION 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.
9. To return the softener to service, press REGENERA- TION once more.
