    Problem with Grant Combi Boiler - no hot water

    Got home late last night but managed to quickly disconnect the pump and you are absolutely right, there is another arrow on the head which is pointing the wrong way! Although it looks identical it seems like I have ordered the wrong pump somehow... Is it possible to unscrew the pump head and...

    Pump is the same way around as the old one, happy it's going the right way. If it's a blockage what's the best way of clearing it? Thanks for the help!

    Yes, all the lights are behaving as they should be. It just runs for five minutes without the heat exchanger getting even warm before the overheat cut off activates. Was wondering if it might be a thermistor?
