    Hi,

    I have a Truma Combi in my MH, I have just put the water heater on and the Orange light comes on no problem to say it is heating up then when it goes out I run the hot water and it is stone cold.

    Heating is working OK

    Any thoughts on how to rectify would be greatfully appreciated
    Thanks
    Gary

    I had the same problem when we first got our motorhome. Make sure that you have taken the cap off the vent for the boiler. When you turn it on do you hear it fire up? If you do then don't run any water for at least 30 minutes and then check it. I think we were trying the water too soon and then it was topping itself up with cold again so we never got past luke warm.

    Hi Gary,
    Hmnn, just been looking through my manuals but no mention of your fault.
    I assume you've checked the usual things like :
    Is there water to the system.
    Have you set the temperature.
    Purged the system ie, turn all the taps on.
    Dump valve closed..
    There is mention of a slow-blow fuse in the pcb but I'd think this unlikely if you have heating.

    Other than the above, sorry, sounds like a
    call to Trauma may be in order.

    Be interested if and when you get a result

    Good luck
    Tony

    Hi Gary,

    If you dont have any luck, give Glenn or Ian a ring on Monday, they will know the answer.

    It takes over an hour to heat the water or at least ours did so give it a bit of time.
