If necessary, do the Calibration proce-
dure [AUTO SETUP].
Check the correct position and condi-
tion of the electrode.
Check the PCB.
Check the gas valve and replace it if
necessary.
Reset the fault and do the Calibration
procedure [AUTO SETUP].
If necessary, replace the gas valve or
PCB.
Check the gas supply, fume ducts and
condensate drain. Check the correct
position and state of the electrode
After about 3 minutes the error is reset.
Reset the fault and do the Calibration
procedure [AUTO SETUP].
Initially solve the problem, reset the
fault and check correct ignition.
Do the Calibration procedure [AUTO
SETUP]. Replace the board if neces-
sary.
Reset the fault and check for correct
ignition. Do the Calibration procedure
