    My first post im a registered engineer, not used forms before so hoping I've posted this right?

    I have attended a no heat or water on my neighbours bias compact he combi,

    Fan would not opperate, they were no power at the fan and fuses good so I determined that is was a pcb fault.

    Replaced pcb- fan now operates but.
    Only fires for hw not for heat when called for,

    Also the actuator on diverter valve does not opperate.

    So I now believe that the air pressure switch maybe faulty as well as the diverter actuator.

    Could it be that these parts could have been damaged from a power surge when the pcb packed in?

    Cheers Riley,
    I will send you a picture of my card.

    Im just trying to get back out on the tools again so a bit rusty on fault finding on the newer appliances, been working at a college for some time now so 80% of my plumbing knowledge is all pipe bending calculations and bending skills

    I've found the parts were not too expensive so I've ordered them and try and see how I get on.
