AUTOMATIC ELECTRONIC DIAGNOSTICS
This water softener has a self-diagnostic function for
the electrical system (except input power and water
meter). The computer monitors electronic compo-
nents and circuits for correct operation. If a malfunc-
tion occurs, an error code appears in the display.
The troubleshooting chart shows the error codes that
could appear, and the possible malfunctions for each
code.
While an error code appears in the display, all buttons
are inoperable except the SELECT/MENU button.
SELECT/MENU remains operational so the service
person can perform the Manual Initiated Electronic
Diagnostics, see below, to further isolate the problem.
TO REMOVE AN ERROR CODE:
1. Unplug the power supply.
2. Correct the problem.
3. Plug the power supply back in.
4. Wait for at least 8 minutes while the timer operates
the valve through an entire cycle. The error code
will return if the problem was not corrected.

MANUALLY INITIATED ELECTRONIC
DIAGNOSTICS
Use the following procedures to advance the water
softener through the regeneration cycles to check
operation.
Lift off the Salt Hole Cover, remove the top cover
faceplate assembly by unlocking the tabs and lifting,
to observe cam and switch operation during valve
rotation.
1. Press and hold SELECT/MENU for 3 seconds until
"000" shows in the display.
2. The first 3 digits indicate water meter operation as
follows:
000 (steady) = Soft water not in use, and no
flow through the meter.
OPEN A NEARBY SOFT WATER FAUCET.
000 to 199 (continual) = Repeats for each gal-
NOTE: If you don't get a reading in the display with
faucet open, pull the sensor from the valve
outlet port. Pass a small magnet back and
forth in front of the sensor. If you get a read-
ing in the display with the magnet, unhook the
in and out plumbing and check the turbine for
binding (See Figure 18).
3. The last 2 digits in the display indicate POSITION
switch operation as follows:
Correct Switch
Displays
Valve in service, fill, brining,

4. Use the RECHARGE button to manually advance
the valve into each cycle and check correct switch
operation.
