Automatic Electronic Diagnostics

This water softener has a self--diagnostic function for the ele ctrical system (except input power and/or

water meter). The wa ter softener monitors electronic components and circuits for correct operation.

If a malfunction occurs, an error code appears in the display.

The troubleshooting chart shows the error codes tha t could appear, 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.
