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.

hi kerbsidemotors,

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?

Pam

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.,

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.
