    Hello,
    While using the shower, the water started to run cold. When I checked the boiler, it seemed to have lost all electrical power with the display blank. I've checked the fuse which is ok but I can't get it to come on. I'm not qualified but wondered if someone could suggest a possible cause or if there is something basic I could try please.
    Thank you
    Nigel

    You would need to be able to measure AC voltage and trace the supply towards the boiler.

    Many of these faults are caused by accidentally turning off a switched fused spur!

    But if not competent in dealing with mains voltage then calling a boiler engineer would be safer!

    Thanks Tony,
    I did switch off the power at the spurred fused socket below the boiler but have switched it back on again. As I say, I checked the fuse and wiring inside the box - looks fine, and the main fusebox for the house is ok. Do you think by just doing that, it's tripped something? I don't have a meter to check the voltage, is there anything else I can try?
    Many thanks,
    Nigel

    You cannot see electricity and the only way to test is with meters!

    If you cannot do it yourself then call a boiler engineer!

    Thank you Tony. There's a small fuse in the circuit board that had blown. I replaced it a couple of times, but it keeps blowing so I think I'll have to get an engineer. Thanks for your time.
    Regards,
    Nigel

    Thanks for that Tony. I'm in Ashford, Kent. Is that not too far for your mate?
    Best wishes
