    Hi guys,
    As the title says no hot water
    I have a trumatic c 3402 with the brown control panel
    the heating is working but the hot water won't heat up.
    as in the water is cold even when you turn on the hot tap.
    the temperature is the same hot or cold.
    I tried changing to hot water only, and between 40c and 60c but no joy
    Am I after tripping something, or any ideas?
    Thanks for any help

    Are you on EHU? If so check the main trip switch. Is this your first trip from winterising? If so check the frost trip has been reset, else it will continue to drain water. Most important don't worry you'll be right. (y) Cheers. Terran

    Hi, if you're not on EHU then I'm assuring you're heating by gas? Is your thermostat at the "gas" setting?
    Just a thought make sure your external flue cover is removed, otherwise the gas won't ignite for safety reasons when heating water by gas.......

    I would echo MHVirgins comments regarding the external flue cover as we experienced this!! Suddenly remembered the handover instructions and whipped the cover off.
    Note that taking the cover off did not start the water heater but switching it off and then on again did the trick!

    The Truma C3402 is gas only. Obvious question - is the gas on? Must be yes if heating is working. I would get a gas engineer to look at it as it would appear that the water heating part needs fixing/replacing.

    Graham, thanks for this useful information, I didn't realise that this particular model was gas only. I was assuming that it was either/or........you know what they say about never assuming:rolleyes:

    This is weird. As far as I know there is one burner, so if the hot air works so does the water heater. If you select hot air you always get hot water. If you select water only it just turns off the blower.

    Are you sure you are turning the tap the right way ?

    Are waiting at least half an hour ?

    Good point Brian. I've just checked the manual and you're right, there is only a single burner.

    Sorry for not replying.
    quite cold here at the moment so I dumped all the water in case I did damage to the pipework from it freezing.
    eventually I started again from scratch. filled the van and filled the boiler and this time it WORKED.

    hot water YIPEE! heating working as well

    Honestly don't know what I was doing wrong but at least it is working-thank god

    weather freezing again, so drained it just in case. will wait until weather improves and will test it again.



    thanks for all the help.

    just as an aside, I have read on here that you should hoover/clean the fan on the traumatic 3402 c as it can get clogged up and the heating does not work as well

    has anyone done this as I cannot find anything online as to its location or how to do it.

    Brilliant well done! (y) Now if you can figure out what you've done differently you can avoid it happening again ;)

    Great news! Glad you've got it working again......it's a real b*gger not having hot water.
    We take it for granted and are completely lost without it(y)

    I think the hoover reference would have been as part of a service, a few on here are qualified to do it themselves, a few others do it themselves anyway, a lot don't bother with servicing, the rest of us pay once a year for a habitation service.

    It does seem a lot to pay, but what price your safety, not to mention comfort if it helps keep things working, hot water and cold beer for instance (y)

    There are not many of us who have not thought something was seriously wrong, only to find a setting wrong somewhere

    I've just had a look at the manual and can't see any mention of cleaning the fan. It's not something I've done.

    EDIT - I agree fully with what David has said about habitation servicing.

    Hi gjh

    I see that you have the same model no.
    I am heading to france soon so am just trying to find out as much as i can about the heating.
    I did not even know that there was heating in a van, let alone hot water, before we started looking for a van.
    I have run the heating but not overnight.

    Do you find the heating good from that model and what would you have the thermostat at.

    I thought there was no service schedule for Truma Combi's, according to Truma they don't need servicing, unless the earlier ones are different.

    There is no "service schedule" as such in the manual but there are general safety notes and it does make a point of saying that the gas system should be tested every 2 years. All the gas appliances are tested annually as part of our habitation service. That's what I was referring to and what I think David meant.
