19ELECTRONIC DEMAND TIMER FEATURES, AND SERVICE, continuedCalifornia Efficiency RequirementYour water softener has a “High Efficiency” feature with an “ON” or “OFF” setting. This softener settingis shipped in the “OFF” position, which utilizes the maximum rated capacity while most often achievingmaximum salt efficiencies. When installing this unit in the State of California, you MUST turn this settingto the “ON” position which may initiate more frequent recharges, however it will operate at 4000 grainsper pound of salt or higher.If you wish to turn the Salt Efficiency feature “ON” ( icon will show in display), follow the instructionson page 18.feature / service: AUTOMATIC ELECTRONIC DIAGNOSTICS . . . . . . . . . . . . . . . . . . . . . . .The timer computer has a self--diagnostic functionfor the electrical system (except input power andwater meter). The computer monitors the electroniccomponents and circuits for correct operation. If amalfunction occurs, an error code appears in thetimer display.The following chart (below) shows the error codesthat could appear, and possible defects for eachcode. While an error code is displayed, all timer but-tons are inoperable except for the SELECT button.SELECT remains operational so the service personcan make the Manual InitiatedElectronic Diagnostics to furtherisolate the defect, and check thewater meter.ERROR CODE DISPLAYEDErr 01 Err 03 Err 04 Err 05POSSIBLEDEFECT' wiring harness, or connection to switch ' position switch ' motor inop-erative ' valve defect causing high torque' timer (PWA)DEFECTTO REMOVE AN ERROR CODE: (1) unplug transformer (2) correct defect (3) plug transformer in (4)TO REMOVE AN ERROR CODE: (1) unplug transformer (2) correct defect (3) plug transformer in (4)Wait for at least 12 minutes.

First, make the following visual checks.VISUAL CHECKS: (1) Is there electrical power tothe outlet the softener transformer is plugged into?(2) Is there salt in the storage tank? (3) Is the plumb-ing bypass valve(s) directing water for soft waterservice? --see page 6-- (4) Is the valve drain hoseopen to the drain, not elevated too high, and unob-structed? If you do not find a problem with the visualchecks, continue below.NO SOFT WATER TIMER SHOWS WRONG TIMEAND DAY, AND/OR IS FLASHINGElectrical power was off.
