Samantha, firstly the water heater is not a Carver Trumatic, it is a Carver Cascade.
As for the lighting sequence, if you get a yellow light as well as a green, then it is a lack of 12v.
This could be a broken wire, or a problem with the switch or burner module.
You should get it checked out by a competent engineer.

hi it is not a cascade it definataly says carver trumatic on the boiler and the control box is a truma, we have had many vans with the cascade, but never with this system.
It's a Carver 'B0' Damian, produced around 83 to 86 and mostly fitted in ABI vans. It's the forerunner to the Truma Ultrastore and just about identical to the current version!
So Samantha green and orange light but no mention of a red light? it's either green, orange, red, or just green and red, which is it. Or perhaps in other words 3 lights or two?

hi one we switch the water heater switch on the green light comes on and then instantly followed by the orange light and both lights then stay on.
Damian,
A little history lesson:
Carver produced the first storage water heater for touring caravans in 1979 - The Cascade. an all copper mushroom shaped tank. In response Truma produced the Trumastore in 1981. As Carver were only sold in the UK, any caravan manufacturer that was interested in exporting to the continent needed to fit the Truma. Carver were sole agnets for Truma and so they also offered the 30mB Trumastore rebadged as the Carver BO.
1984 carver launched the Cascade 2, followed in by the Cascade 2GE

you are exactly right that is what it says on the top of our boiler sticker a bit worn but that is how i knew it says carver truma etc would you know why we have the green and orange light on together as we are only used to the cascade versions, would the ights mean the same or not?

Hi Gary and John, thanks for the information.
I have not come across one of those yet, thankfully.
I did a search last night, but could only come up with the Truma
Trumatic, which is a blow air heater.

Sam, first it should be green and red, not orange, that's what's confusing me, with three lights green and orange would come on together.
I did ask two lights or three? but as you only talk of two I'll base the answer on that, however I will call 'your orange' red so the rest will make sense.
Green means on and nothing else, red means fail, ie, it's gone through it's start cycle and not detected the flame is lit, this causes the control to shut down and show the red light. Again if three lights it's the same but orange goes out replaced with red.
The start cycle is around ten seconds, so, first green, then if no flame detected red should follow after ten seconds. If however green and red come on together? then the start cycle has reduced to nought seconds, this is a control board fault and needs repair before we can go further.
Thanks for the precise history lesson John, I expected you'd know!
