AUTOMATIC ELECTRONIC DIAGNOSTICS
This softener has a self-diagnostic function for the
electrical system. The computer monitors electronic
components and circuits for correct operation. If a
malfunction occurs, an error code appears in the dis-
play.
The chart below shows the error codes that could
appear, and the possible malfunctions for each code.
Code
Possible Problems
Err01 Motor, Valve Position Switch
Err03 Motor, Valve Position Switch, Wire Harness
Err04 Valve Position Switch
Err05 Electronic Control Board (PWA)
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 Manually Initiated Electronic Diagnostics to
further isolate the problem.
TO REMOVE AN ERROR CODE:

. Unplug the power supply.
2
. Correct the problem.
3
. Plug the power supply back in.
4
. Wait for at least 8 minutes while the timer operates
the valve through an entire cycle. The error code
will return if the problem was not corrected.
