Truma water heater problem
I have a 2013 Ford Tribute T-615 motorhome with an Ultrastore Rapid GE Truma gas and electricity water heater.
It works fine with electricity, but I have a problem with the gas. It will fire up for about 15 seconds then automatically cuts out.
I got it checked out when it went for its habitation check and they said it was fine and sure enough when I got it home and tried it, it was ok.
But on the first trip out a few weeks later I still had the same problem and I cannot get it to work.
Any one got any idea what the problem might be and if I can fix it myself? I have tried all the usual stuff - changing gas cylinder to up the pressure, leaving it and retrying a number of times, ensuring boiler exhaust cover is off etc.
Grateful for any input.
Thank you
