Manual Advance Regeneration Check --- Model WHES30
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 electronic control display must show a steady time (not flashing). If an error code
shows, first press the
PROGRAM button to enter the diagnostic display.
1. Press the RECHARGE button and hold in for 3 seconds. RECHARGE begins 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.
If water does not enter the tank, look for an obstructed nozzle, venturi, fill flow plug, brine tubing, or
brine valve riser pipe.
2. After observing fill, press the
RECHARGE 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. This may take 15 to 20
minutes to notice.
NOTE: Be sure water is in contact with the salt, and not separated by a salt bridge... see “Breaking
A Salt Bridge” section.
If the water softener does not draw brine, check for (most likely to least likely)
•
Dirty or plugged nozzle and venturi, see “Cleaning the Nozzle and Venturi” section
• Nozzle and venturi not seated on the gasket, or gasket deformed
• Restriction in valve drain, causing a back--pressure (bends, kinks, elevated too high, etc.),
see “Install Valve Drain Hose” section
• Obstruction in brine valve or brine tubing
• Inner valve failure (obstructed outlet disc, wave washer deformed, etc.)
NOTE: If water system pressure is low, an elevated drain hose may cause back pressure, stopping
brine draw.
3. Again, press the RECHARGE button to move the softener into backwash. Look for a fast flow
of water from the drain hose.
An obstructed flow indicates a plugged top distributor, backwash flow plug, or drain hose.
