Cure
See fault F07
Check the electrical system
Fill the system
Check the water pressure switch
Check the wiring or replace the sensor
Reconnect the external probe or disable the out-
side temperature mode
Check the correct positioning and operation of
the heating sensor
Check the correct positioning and operation of
the return sensor
Check the circulating pump or system blockage
Vent the system
Check the correct positioning and operation of
the heating sensor
Check the correct positioning and operation of
the return sensor
Check the circulating pump or system blockage
Vent the system
Check the PCB parameter and modify it if neces-
sary
Check parameters and carry out a 100% calibra-
tion
Check the position of the electrode, replace it if
necessary. After replacement, repeat the 100%
calibration
Reset the fault. Open the hot water tap and and
wait for the flame to stop flashing (about 2 min-
utes)
Check the earth connection, to the electrode &
replace the PCB if necessary
Try disconnecting the power supply to the boiler
for 10 seconds and replace the PCB if necessary
Load the parameters
Repeat the loading procedure within 5 minutes
from the boiler power supply and replace the
BCC Service key if necessary
Connect the PCB to the Gas valve
Check the wiring or replace the Gas valve
Disconnect the power supply to the boiler for 60
seconds and then reinstate the boiler
Reload the firmware or replace the PCB
