As per the title, the PCB on the boiler failed after 10 years - so I've replaced it by myself (exchanged the faulty one with a refurb one and with a 1-year warranty). All is good, but the hot water is not hot enough! Even if I turn the bath or kitchen tap to the max.
Is it possible that this is the adjustment somewhere or that refurbed PCB is storing some weird values? Not sure how to reset everything to default.
Any guidance is much appreciated.
