cod. 3541V300 - Rev. 00 - 02/2021
Cure
Check that the fume ducts and the con-
densate trap are not blocked. Check
the correct gas supply pressure.
Do a manual calibration to adjust the
CO . If necessary, do a complete
2
manual calibration.
If the problem persists, replace the
PCB.
Check that the fume ducts and the con-
densate trap are not blocked. Check
the correct gas supply pressure.
Do a manual calibration to adjust the
CO . If necessary, do a complete
2
manual calibration.
If the problem persists, replace the
PCB.
Reset the fault and proceed with com-
plete manual calibration.
Initially solve the problem, reset the
fault and check correct ignition.
Do a complete manual calibration and,
if necessary, replace the PCB.
Reset the fault and check for correct
ignition. Do a complete manual calibra-
tion and, if necessary, replace the 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.
Check if there are pressure peaks in
the DHW circuit. If necessary, modify
parameter b11.
Check the correct position and condi-
tion of the electrode.
Check the PCB.
Check the gas valve and replace it if
necessary.
