    If the programmer doesn’t light up and you have 240v on block x2 (live and neutral in ) then remove the programmer plug from x4 and link the brown to the white for hot water and brown to grey for c/h.
    Could be prog is faulty. Isolate fully as all is 240volts! (I’m assuming this is a non greenstar heat slave. )

    Do you have an integral or remote programmer?

    Could a sensor in the boiler stop it from powering up or would the lcd screen come on anyway with just power to it ?
