Cure
Check the circulating pump and hea-
ting system
Vent the system
Check the correct parameter setting
Disconnect the power supply to the
boiler for 60 seconds and then reins-
tate the boiler
Do complete manual calibration
Reset the fault and do complete
manual calibration.
If necessary, replace the gas valve or
PCB.
Check that the fume ducts and the
condensate trap are not blocked.
Check the correct gas supply pres-
sure.
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 condensate trap are not blocked.
Check the correct gas supply pres-
sure.
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
complete 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 cali-
bration and, if necessary, replace the
PCB.
Check the gas supply, fume ducts
and condensate drain. Check the
correct position and state of the elec-
trode 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.
