Combined Heating and Water not working

    We had the central heating and water heating system in our house replaced about 2 years ago with a nice SEI approved system which has been pretty good up until now.
    Right now the Myson control panel backlight is not on, but is still displaying the time etc. I have a feeling that this is the problem, and that there is an easy solution, but for the life of me I can't work out what it is...
    The boiler appears to be OK, with the gas pressure at about 0.6 bar, well above the 0.2 required.
    I have tried turning off the switch below the timer, and when I do the timer goes blank until I turn it back on again.
    There are no electrical fuses tripped, and the LED on the switch below the timer is on.
    It's been like this for a couple of days, so our only hot water is from the kettle or electric shower, and the house is getting a bit cold... :-)
    It's amazing how little information on this kind of thing is on the web.

    Does anyone have any idea what might be wrong?

    It's possible it is the programmer but you will need to have some one take a look. Do you know where your zone valves are? might be in your hotpress. It will be a brass valve with a plastic box on it. If you can find them there is a lever on it that you can slide to manual and this should start the boiler. You will have to slide it back to turn it off again.

    You should call someone in to check the controls out.

    I'll give that a go, but I remember the installer saying something to me about the significance of the backlight not being on, and I'm trying to remember what it was....
    Thanks.

    I set both zone on the control panel to 'on' and then set both valves to manual, but there was nothing.
    The lights didn't come on on the valves, and the boiler didn't fire up either.
    I am thinking I'm going to need professional help on this one... :(

    If it's in any way relevant, it's a Myson dual zone control panel, myson valves, a little myson wiring box in the hot press and a Baxi boiler.
