Troubleshooting

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-

lon of water passing 

through the meter.

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:

4

.  Use the RECHARGE button to manually advance 

the valve into each cycle and check correct switch 

operation.
