My Baxi boiler is flashing on red 50 and there is no heating or hot water. When you turn the dials for the temperature and hot water, there is no click. Is it the PCP board?

Answer from Lee Carruthers, technical officer – heateam, the service division of BDR Thermea:
It sounds like the boiler is going to need a new PCB or air pressure switch. A gas safe engineer can call from site regarding checks on fan power APS voltages etc.
