AUTOMATIC ELECTRONIC DIAGNOSTICS
The face plate computer has a selfĆdiagnostic
function for the electrical system (except input
power and water meter). The
computer monitors the electronic
components and circuits for corĆ
rect operation. If a malfunction occurs, an error
code appears in the face plate display.
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
INITIATE ELECTRONIC DIAGNOSTICS to further
isolate the defect, and check the water meter.
CODE
POSSIBLE DEFECT
MOST LIKELY LESS LIKELY
Err 01 motor inoperative / wiring harness or connection to switch / position switch / face plate
Err 02 face plate
Err 03 motor inoperative / face plate
Err 04 face plate / position switch
Err 05 face plate
PROCEDURE FOR REMOVING ERROR CODE FROM FACE PLATE: 1. Unplug transformer 2. Correct defect
3. Plug-in transformer 4. Wait for 6 minutes. The error code will return if the defect was not corrected.
MANUAL INITIATED ELECTRONICS DIAG-
NOSTICS
1. To enter diagnostics, press and hold the
SELECT button until 000 - - shows in the
display.
A. The first 3 digits indicate water meter operaĆ
tion as follows:
000 (steady) = Soft water not in use, and no
flow through the meter.
Ċ OPEN A NEARBY SOFT WATER FAUCET Ċ
000 to 199 (continual) = Repeats display for
each gallon of water passing through the meĆ
ter.
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.
B. The letter (P) and dash (or dashes) indicate
POSITION switch operation. If the letter apĆ
pears, the switch is closed. If the dash shows,
the switch is open.
Use the ON/OFFĆHOLD (Recharge Now) butĆ
ton to manually advance the valve into each
cycle and check correct switch operation.
