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 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.
