d2 is the code symbol for delay after central heating. and is not a fault code.. however if this is coming on then stopping the operation of the boiler then it usually points to a sticking diverter valve.

There is a parameter on the pcb to change would take 30seconds to do. Never replace ur pcb for these faults. Hold down reset untill u see t5 press reset 1 more time it will then say p01 press the heating temp button until u see p02 press the hot water temp button until it changes to numberv2 and that will fix ur problem
