I am now wondering if there is anything wrong with the unit at all and how I can check that both elements receive voltage? I would greatly appreciate your knowledge and input please? Many thanks. Robert
I read your strip down post with much interest. We had a hab check done recently and the engineer reported that one of our elements was not working. How he deduced this without taking the Truma to bits I don't know. Anyhow, took his word for it. I have now got the unit out and removed the end cover. I have measured the resistance and both read 58 ohms which probably means they are both okay, (230*230)/900=58.
I found your Truma boiler repair posting from April 16 2018 online so I joined this site to get more info and pictures. The problem now is that I cant find it on here. There is a posting from 26th April with no content I can find. Is it possible for you to send me the posting complete with the pictures as I am having the same problem as you
Just been avidly reading your Truma boiler repair posting, as I have the same issue, and hopefully will be attempting mine. Looking at your photos, do you think it would be possible to test/check the elements resistance, at the printed circuit board position (adjacent to where the mains wire connects)
My Truma boiler has frozen and has a little bit inflated, so there is no space between the boiler and the fins on some points. I bent the fins on theese points to create some space there. But then I noticed that the plate is touching the boiler too, because the boiler has inflated there too. I don't know the reason, why the plate is there and if it has/hasn't touch the boiler or the fins.
Hello, I have read your great thread about disassembling Turma combi. I have a question of the image https://www.motorhomefun.co.uk/forum/media/img_3480.22866/. Do you have any idea, why there is the plate above the fins? Does the plate touch the fins, or is there some space between? Or does the plate touch the boiler?
