AUTOMATIC ELECTRONIC DIAGNOSTICS
This water softener has a self-diagnostic function for
the electrical system (except input power and/or water
meter). The water softener monitors electronic com-
ponents and circuits for correct operation. If a mal-
function occurs, an error code appears in the display.
While an error code appears in the display, all buttons
are inoperable except the PROGRAM button. PRO-
GRAM remains operational so the service person can
perform the Manual Advance Diagnostics, see below,
to further isolate the problem.
Procedure for removing error code from display:
1. Unplug power supply from electrical outlet.
2. Correct problem.
3. Plug power supply back in.
4. Wait 8 minutes. The error code will return if
the problem was not corrected.
MANUAL ADVANCE DIAGNOSTICS
Use the following procedures to advance the water
softener through the regeneration cycles to check
operation.
Lift off the salt lid, remove the top cover by unlocking
the tabs in the back and rocking forward, to observe
cam and switch operation during valve rotation.
1. Press and hold PROGRAM for 3 seconds until
"000" shows in the display, then release.
2. The 3 digits indicate water meter operation as fol-
lows:
000 (steady) = Soft water not in use, and no flow
through the meter.
Open a nearby soft water faucet.
000 to 140 (continual) = Repeats for each gallon
3. Symbols in the display indicate POSITION switch
operation (See Figure 39).
4. Use the RECHARGE button to manually advance
the valve into each cycle and check correct switch
operation.
NOTE: Be sure water is in contact with the salt, and
not separated by a salt bridge (See "Breaking
A Salt Bridge" section).

5. While in this diagnostic screen, the following infor-
mation is available and may be beneficial for vari-
ous reasons. This information is retained by the
computer from the first time electrical power is
applied to the electronic controller.

UP button to display the number of
days this electronic control has had electrical
power applied.

b. Press the
DOWN button to display the num-
ber of regenerations initiated by this electronic
control since the code number was entered.
6. Press and hold the PROGRAM button until the
model code (LLCS) shows in the display. This
code identifies the softener model. If an incorrect
model code is displayed, the softener will operate
on incorrect configuration data.
7. To change the code number, press the
s
DOWN button until the correct code shows.
8. To return to the present time display, press the
PROGRAM button.
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, 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 soft-
ener's valve advances from the service to fill posi-
tion. Remove the brinewell cover and, using a
flashlight, observe fill water entering the tank.
