sorry can't help but didn't want your wee sorry blue face hanging around overnight as everyone else seems to have gone to bed! My hubby maybe could help as he fixed the truma water heater on our old caravan last year. although an Abi and much older than your Elddis. It too would work on gas but nothing when switched to electric. Unfortunately, due to an excess of Gordons and Schwepps, he is asleep on sofa and I cannot waken him. I will show him your post in the morning if that is any help?

There are two gas models BN/BS with 10litre or 14 litre boiler. apart from the fuses, you cannot repair these things your self. Like an electric kettle the 1.5KW element goes. My advice is: Drain it out, unscrew it from the Gas and Water. Take off the cables and take it to a Truma main dealer for service. If you take it to a caravan dealer, then 9 times out of 10 they will sell you a new one, and the gas ones are not cheap. Good luck!.

dear all please help haveing problem with truma water heater works fine on gas but will nut heat on elctric at all,.
have checed all fuses and all ok van is 2004 elddis534L.
Is your 534L the Avante version? Have you tried the following - in the on/off switch for the boiler there is a cartridge fuse on our Avante 482 of the same vintage. Is this OK? Also have you checked the MCB switches? Oddly enough they should be UP for on.
Looking at the wiring diagram for the Avante as well as other Explorer Group models it would appear that the water heater is on a spur which includes two mains power points. The mains spotlights also work from the same source on the MCB box. Might be worth checking that all these are working OK. Also check if your fridge is working OK on 240v as this also takes its power from the same outlet on the MCB.If all these are OK then that would suggest to me a problem with the water heater.
Yes vic it,s an avante but every thing else is working fine i spoke to dealers a saleman., but he said he thoughtit was heating element..
it works fine on gas and all fuses are fine but he said the 2nd switch above door was water heater only also there was no reset button on the truma system as was on carver.,
------------- IAN avant d,i,y er try to help if i can.
The Truma boiler does have an over-temp reset switch but unlike the Carver it's self resetting. What you need to do is disconnect the mains supply to it, in other words switch the electric heater off, now wait several minutes for the reset switch to cool down and it will then automatically reset.
It's called a 'Self Hold' reset and how it works is this, when it trips it of course disconnects the power to the water heating element but as it does this it also connects a tiny internal heating element to the mains which keeps it above the trip temperature. So until the mains power is switched off it cannot cool down and reset.
Problem can be if you don't know how it works or if you don't give it long enough to cool and switch back, it then reheats itself and you need to wait all over again... but this time for longer!!
Probable reason for it tripping is not switching it off last time out, if you then get to site and hook the van up before you've filled the boiler it overheats and trips out.
