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.
