Troubleshooting
AUTOMATIC ELECTRONIC DIAGNOSTICS
The electronic controller has a self-diagnostic function
for the electrical system (except input power and
water meter). The computer monitors the electronic
components and circuits for correct operation. If a
malfunction occurs, an error code appears in the dis-
play.

The chart on the previous page shows the error
codes that could appear, and possible problems indi-
cated by the codes. While an error code is displayed,
all timer buttons are inoperable, except for the
SELECT button. SELECT remains operational so the
service person can make use of the Manually Initiated
Electronic Diagnostics to further isolate the defect,
and check the water meter.
TO REMOVE AN ERROR CODE:
1. Unplug the transformer.
2. Correct the problem.
3. Plug the transformer back in.
4. Wait for at least 6 minutes while the electronic con-
troller operates the valve through an entire cycle.
The error code will return if the problem was not
corrected.

MANUALLY INITIATED ELECTRONIC
DIAGNOSTICS
1. To enter diagnostics, press and hold the SELECT
button until “000 - -” appears 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 = Repeats for each gallon 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 36).
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.
5. While in this diagnostic screen, the following infor-
mation is available and may be beneficial for vari-
ous reasons. This information is retained by the
computer from the first time electrical power is
applied to the electronic controller.
a. Press the UP () button to display the number
of days this electronic control has had electrical
power applied.
b. Press the DOWN (–) button to display the num-
ber of regenerations initiated by this electronic
control since the model code number was
entered.
