About two months ago we suddenly found that our morning ritual of having the hot water heater come on at 7am to heat the water, and then switch over to take the ice out of the air, stopped working.
After reading up on some online forums, I found the most likely cause was that one of the two 900w elements to have failed. The gas was working perfectly and it still worked on power but just ever so slowly.

The van was due to have its annual check for water ingress so I asked one of the really busy techies there to check the resistance on the elements. They were both the same.. strange.. if one is blown, it will have a different resistance reading.
A couple of weeks later, I took Rafe to another RV workshop where I was told there were a couple of “clever truma people” who would sort it for me. After a week of having the van and removing the heater, cleaning and reinstalling it, it still wasn’t working.
A big disappointment !
Back to square one.
So.. time to find a Truma Guru and get this fixed once and for all..
While we were in Wellington recently, we were in a shopping mall and Fiona was doing the shops. I was sitting in the “husband waiting chair” . I got on the phone and via some friends, I was put onto Peter Webster who owns RV Repairs who are just up the road in Albany.. yippee!
Still sitting in the “Husband waiting chair” I called Jan at RV Repairs and booked Rafe in for some heater surgery.
After taking Rafe up on a Saturday morning, Peter’s electronics man, a really nice guy also called Peter, who tested the heater with an amp meter found it was only pulling just over 1 amp on full bore.. it should be pulling about 6-8 amps. So he started to take the unit out of Rafe and stick it on their specialist Truma test trolley.
Within an hour, I got a phone call saying that one element had a normal resistance, the other was as dead as a dodo.
After trying to take out the old element, they found the element had virtually exploded in the heat exchanger and when it went, it had damaged the heat exchanger.. two choices, new heat exchanger or new unit.
Heat exchanger $2000 plus odd with two elements. There would be several hours to install the heat exchanger in the heater on top of this. The other choice was a new Heater unit .. mid/late $3000’s. I chose the heater. At last the thing will now heat properly again 🙂
Truma’s new policy for replacement elements is to provide a heat exchanger with two elements due to installation failures!
I was absolutely rapt with the two Peter’s getting straight in to solve the problem without any fuss.. They’re clever guys too . Peter W (the owner) is a boat builder and spray painter by trade and the other Peter an aeronautical engineer so they’re perfect for solving a Truma heater problem 🙂 and with lots of knowledge left over !
They’re also motorhomers themselves and great fun with not just two Peter’s but three.. 🙂
