    Is their a guide to replace the diaphragm on the above boiler as the pin isn't quite reaching the micro switch for domestic hot water one of the silver slotted screws at the back seems impossible to get a screwdriver on it, or do you undo the 2 brass slotted screws to the left of the diaphragm housing.
    I have read other people saying its only a 20 minute job !

    Would appreciate a guide or info how to do this job.

    Thanks

    Hello is the diaphragm housing secured by two brass screws ? Do I turn off the water in the street and then open the drain valve to drain the boiler or can I get away without draining the boiler ? Thanks

    you dont need to drain the boiler , turn the water off at the cold water inlet valve below the boiler open a hot tap till the water stops running and take the housing out, yes held by two screws
