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 transformer.
2. Correct the problem.
3. Plug the transformer 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.

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.

the valve into each position and check correct switch
operation (See Figures 29-31).
3. While in the "aspirate" (A) position, check the noz-
