AUTOMATIC ELECTRONIC DIAGNOSTICS
The face plate computer 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 malfunc­
tion occurs, an error code appears
in the face plate display. СГГ
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. The SELECT button remains operational so
the service person can make the Manual Initiated
Electronic Diagnostics to further isolate the defect,
and check the water meter.

WATER METER (A) SWITCH (B)
A. 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 display for
each gallon of water passing through the meter.
If you don’t get a reading in the display, with the
faucet 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.
