AUTOMATIC ELECTRONIC DIAGNOSTICS
The face plate computer has a self7diagnostic function for the electrical system (except input power and water meter). The computer monitors the electronic components and cir7
cuits 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 SELECT button. SELECT remains operational so the service person can make the MANUAL INITIATED ELEC7 TRONIC DIAGNOSTICS (below) to further isolate the defect, and check the water meter.

PROCEDURE FOR REMOVING ERROR CODE FROM FACE PLATE: 1. Unplug transformer 2. Correct defect 3. Plug in transformer 4. Wait for 6 minutes. The error code will return if the defect was not corrected.
MANUAL INITIATED ELECTRONICS DIAGNOSTICS
1.To enter diagnostics, press the SELECT button and hold for 3 seconds.
You will see the following display, showing valve cycle position, position switch status (open or closed), and turbine operation.

position switch
indicator (open) turbine count (no water flowing)
TURBINE OPERATION: If no water is flowing through the softener, the turbine indicator displays 3 zeros. When water is flowing, the flow bar scrolls across the display, and a 000 to 199 count repeats for each gallon of water passing through the turbine. To check for positive operation of the turbine if zeros are shown, open a nearby soft water faucet and observe the turbine count and flow bar.
If you dont get a reading in the display, with facuet open, pull the sensor from the valve outlet port. Pass a small magnet back and forth in front of the sensor. You should get a reading in the display. If you get a reading, unhook the in and out plumbing and check the turbine for binding.
POSITION SWITCH STATUS: WIth the valve in service, or any of the recharge cycles, the switch
indicator will show open 
. While the valve is rotating from 1 position to another, the indicator will show the switch closed 
. A defect is probable if indications vary from this pattern.
