Water heater problem

We have a Truma water heater fitted in our caravan. When we switched it on yesterday we heard it click on then 30 seconds later it clicked off, its not working. It was fine last week when we were away. We have changed the fuse, switched the mains off for
30 minutes and there's plenty of water in the system. I have read about a reset switch but can't locate one on my system. We're due to go to Ireland tomorrow and don't have time to take it to be looked at. Any ideas please.

    you dont say which type of Truma....im familar with the Combi 4E and 6E.....which are both space heaters and water heaters.

    there is a cover on the top of the unit which needs to be slid off and you will see a round shaped recess (hole....)...the red reset button is down at the bottom of this hole and requires a pencil or similar to press fully home....

    have you tried other powers sources....ie gas on its own, just to check the heater is actually working and its not the electric (mains) supply to it?

    Thank you for your replies. It is an Ultrastore Rapid if that makes sense. I can't slide the lid off but it appears to be working although it was switched off at the panel. We have hot water! Not sure if it is gas powered now perhaps , how would we know?

    You may be able to hear Burner from insde the Van if not - Turn Off Gas Supply - open a Hot Tap and drain water untill Cold - turn Off tap - Turn Gas Back On - go outside to where Exhaust Outlet is situated  - you should be able to hear Burner and feel Exhaust Gas Heat if the burner has Ignighted.

    What are Control Panel lights showing?

    Did you forget to remove the gas outer cover and after a few seconds the heater realizes and switches itself off?

    Our Truma Ultrastore  has two completely separate controls - one for gas (which unfortunately looks like an electric switch) and the other for electricity.  They are in separate areas of the van, too!  Perhaps yours is the same.

    Thank you all for your help. We have taken the cover off as we're worried about gassing ourselves! It only has one control ValDa which is why we don't know whether it is working on gas. We're moving on tomorrow so will try your suggestions out at the next
    place.

    As you say your Heater has only one control, I think you may have the Ultrastore Rapid GE fitted in your Van.

    You may wish to download this - http://www.truma.com/downloadcenter/ultrastore_rapid_installation_instruction.pdf

    It includes the operating instructions and a note that - If the cowl is positioned vertically below an opening part of a window, the water heater must be fitted with an automatic shut-off device to prevent operation when the window is open.

    Hope this is of Help.

    You won't gas yourself. The gas heating assembly is sealed from the caravan, and a thermocouple prevents gas escaping when the flame isn't lit. Many people use gas safely to heat their water off EHU. In the longer term, it sounds like your electric element
    is faulty, causing the safety trip to cut out.
