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.
MANUAL INITIATED ELECTRONIC
