Troubleshooting
While an error code appears in the display, all buttons
are inoperable except the SELECT button. SELECT
remains operational so the service person can per-
form the Manual Advance Diagnostics, see below, to
further isolate the problem.
Procedure for removing error code from
display:
1
. Unplug transformer from electrical outlet.
2
. Correct problem.
3
. Plug in transformer.
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 SELECT for 3 seconds until “000”
shows in the display, then release.
2
. The 3 digits indicate water meter operation as
follows:
000 (steady) = Soft water not in use, and no flow
through the meter.
Open a nearby soft water faucet.
000 to 199 (continual) = Repeats for each gallon
of water passing through
the meter.
3
. The letter “P” and a dash (or dashes) indicate
POSITION switch operation (See Figure 40). If the
letter appears, the switch is closed. If the dash
shows, the switch is open.
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
information is available and may be beneficial for
various 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 number
of regenerations initiated by this electronic control
since the code number was entered.
6
. Press and hold the SELECT button until the model
code (rH32) shows in the display. This code
identifies the softener model. If an incorrect model
code is displayed, the softener will operate on incor-
rect configuration data.

r
UP or
s
DOWN button until the correct code shows.
8
