AUTOMATIC ELECTRONIC DIAGNOSTICS
The face plate has a self9diagnostic function for the electrical system (except input power). The face plate monitors the electronic components and circuits for correct operation. If a malfunction
occurs, an error code appears in the face plate display.
The chart below shows the error codes that could appear, and the possible defects for each code.
While an error code appears in the display, all face plate buttons are inoperable except the SET button. The SET button remains operational so the service person can make the MANUAL ADVANCE DIAGNOS9 TICS to further isolate the defect.

PROCEDURE FOR REMOVING ERROR CODE FROM FACE PLATE: 1. Unplug transformer 2. Correct defect 3. Plug9in transformer 4. Wait for 6 minutes. The error code will return if the defect was not corrected.
FACE PLATE REPLACEMENT: Be sure the valve is in service position (observe valve cycle indicator. . . see below) when replacingthe face plate.
If, after installing and programming the replacement face place, the valve is not in service position, do the follow9 ing to assure correct cycle orientation, or timing, between the face plate and valve.
Use the MANUAL ADVANCE procedures, below. With the RECHARGE NOW button, advance through the recharge cycles until the valve stops in service position, and RECHARGE no longer flashes in the timer.
NOTE: The valve motor may automatically drive through several valve positions while searching for service.
MANUAL ADVANCE DIAGNOSTIC
Use the following procedures to advance softener valve through regeneration cycles to check operation.
Remove top cover to observe valve rotation.
