Observation:
When a new PCB is fitted to the appliance it will need to reset when the appliance is powered up for the first time.
If the appliance will not reset make sure all connections have been refitted correctly and that the BCC has been fitted.
The PCB's fitted to the boiler at production are factory set for the boiler model and output.
The replacement primary PCB's are supplied as a universal spare part and as such are not pre-set so a Boiler Chip Card (BCC) MUST also be ordered for your specific boiler range and output.
Ensure that the correct chip is installed and that it is fitted the correct way round with "TOP" facing up.
