Automatic Electronic Diagnostics
This water softener has a se lf--diagnostic function for the electrical system (except input power and/or
water meter). The water softener monitors electronic components and circuits for correct operation.
If a ma lfunction occ urs, an error code appears in the display.
The troubleshooting chart shows the error code s that could appea r, and the possible malfunctions for
each code.
While an error code appears in the display, all buttons are inoperable except the PROGRAM button.
PROGRAM remains operational so the service person can perform the Manual Advance Diagnostics,
see below, to further isolate the problem.
