MANUALLY INITIATED ELECTRONIC
DIAGNOSTICS
Use the following procedures to advance the filter
through the recharge cycles to check operation.
Remove the top cover faceplate assembly by unlock-
ing the tabs and lifting, to observe cam and switch
operation during valve rotation (See Figure 31).
1. Press and hold for 3 seconds the SELECT button,
until one of the screens shown in Figure 30 is dis-
played. If the valve is in service, backwash or
aspirate position (observe markings on the valve
cam), the display should show “000 - -”, meaning
the position switch is open. When the valve is
moving, the display should show “000 - P”, mean-
ing that the position switch is closed.

2. Use the RECHARGE button to
manually advance
the valve into each position and check correct switch
operation (See Figures 32-34).
3. While in the “aspirate” (A) position, check the noz-
zle & venturi by removing the screen from the
barbed fitting on the inlet of the check valve and
determining whether there is suction. Put the
screen back in place when finished checking.
4. 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
á
UP button to display the number of
days this electronic control has had electrical
power applied.
b. Press the
â
DOWN button to display the num-
ber of automatic or manual recharges initiated
by this electronic control since the model code
number was entered.
5. Press the SELECT button and hold in for 3 sec-
onds until the model code shows in the display.
The model code should be “HAAIF”. If the wrong
number shows, the filter will operate on incorrect
configuration data.

Troubleshooting
FIG. 29
AUTOMATIC ELECTRONIC DIAGNOSTICS
This filter has a self-diagnostic function for the electri-
cal system. The computer monitors electronic com-
ponents and circuits for correct operation. If a mal-
function occurs, an error code appears in the display.
The chart below shows the error codes that could
appear, and the possible malfunctions for each code.
Code
Possible Problems
Err01 Motor, Valve Position Switch
Err03 Motor, Valve Position Switch, Wire Harness
Err04 Valve Position Switch
Err05 Electronic Control Board (PWA)
While an error code appears in the display, all buttons
are inoperable except the SELECT button. SELECT
remains operational so the service person can per-
form the Manually Initiated Electronic Diagnostics 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.
