AUTOMATIC ELECTRONIC DIAGNOSTICS
This conditioner/refiner has a self-diagnostic function for
the electrical system (except for input power and/or
water meter). The controller monitors electronic com-
ponents and circuits for correct operation. If a malfunc-
tion occurs, an Error code is displayed (See Figure
132).
FIG. 132
The troubleshooting chart on the previous page shows
the error codes that could appear, and the possible mal-
functions for these codes.
When an error code appears in the display, pressing
SELECT () will display the Diagnostics screen (See
Page 21), so a service technician can further isolate the
problem.
REMOVING ERROR CODE
1. Unplug transformer from electrical outlet.
2. Correct problem.
3. Plug in transformer.
4. Wait for eight minutes while controller operates valve
through an entire cycle. The error code will return if
the problem was not corrected.

MANUAL DIAGNOSTICS
1. Display the Diagnostics screen, following the proce-
dure on Page 21.
2. Press the DOWN () or UP () buttons to scroll
through the list. The following items are displayed:
Time (current)
Position time (counts down the time remaining
in the current valve position)
Current position (of the valve: service, fill,
brine, backwash, fast rinse or moving) See
“Manual Advance Recharge Check” on next
page for position verification.
Requested position (of the valve)
Motor state (on or off)
Valve position switch (open or closed)
Turbine count (indicates water flow) See fol-
lowing section for turbine diagnostics.
Tank light switch (open or closed)
RF module (detected or not)
Error code
FIG. 133
3. A steady display of “0” (zero) indicates no water flow
through the meter (i.e. no conditioned water being
used).
4. Open a nearby conditioned water faucet.
5. The number in the display should count upward from
0 and reset for each gallon of flow (at 200 on some
models, for example).
6. If the display reading does not change with the
faucet open, pull the wire harness from the valve out-
let port (See Figure 134).

7. Pass a small magnet back and forth in front of the
sensor.
8a. If the displayed Turbine Count does count upward
with each pass of the magnet, disconnect the outlet
plumbing and check the turbine for binding.
8b. If the displayed Turbine Count does not count
upward with each pass of the magnet, the sensor is
probably faulty.
CHECKING THE TURBINE
1. Display the Diagnostics screen, following the proce-
dure on Page 21.
2. Press the DOWN () button to scroll through the list
until Turbine Count is displayed (See Figure 133).
