Troubleshooting
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 dis-
play:
1. Unplug transformer from electrical outlet.
2. Correct problem.
3. Plug in transformer.
4. Wait 6 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 Hole Cover, remove the top cover by
unlocking the tabs in the back and rocking forward, to
observe cam and switch operation during valve rota-
tion.
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
of water passing through
the meter.
3. Symbols in the display indicate POSITION switch
operation (See Figure 35).

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.
a. Press the
r UP button to display the number of
days this electronic control has had electrical
power applied.
b. Press the s 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 (“LL40” for Model WHES40) 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.

r UP or
s DOWN button until the correct code shows.

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.
