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 elec-
tronic components and circuits
for correct operation. If a
malfunction occurs, an error
code appears in the face plate
display.
MOST LIKELY
CODE
Err1 motor inop. / wiring harness or connection to switch / position switch / face plate
Err2 face plate
Err3 motor / face plate
Err4 face plate / position switch
Err5 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.
