AUTOMATIC ELECTRONIC DIAGNOSTICS
This water softener has
a self-diagnostic function
for the electrical system
(except into power and/or
water meter). The water
softener monitors electronic
components and circuits
for correct operation. If a
malfunction occurs, an error
code appears in the display.
While an error code appears in the display, all buttons
are inoperable except the MODE/SET button. MODE/
SET remains operational so the service person can
perform the Manual Advanced 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.

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

number of regenerations initiated by the
electronic control since the code number was
entered.

mode code (H31 for the GXMH31H) shows in
the display (see Figure 20). This code identifies
the softener mode. If an incorrect model code is
displayed, the softener will operate on incorrect
configurations data.
7. To change the code number, press the
DOWN button until the correct code shows.
8. To return to the present time display, press the
MODE/SET button.
9. Press the MODE/SET button to return to the
present time display. If the code was changed,
