    Last time I looked at one of those with that fault, a bit of rusty metal had fallen down from the vent and was stopping the flame heating the thermocouple. Are you sure you cleaned it out properly? If so, and the thermocouple is definitely getting properly hot, try fitting a new thermocouple.

    I had this happen when I filled the water tank up and set about start of season trials. I'd had the little relief valve set the wrong way and as a consequence the whole carver unit was drenched with water. After removing the cover and giving it a good cleaning and drying - and - after maybe a dozen 15 second cut off and red light situations it eventually came good.

    quite agree- thermocouple
    but these heaters , i think, have those funny wire ends , just like the sparker wire, not looking anything like t/couples as we know them . same on the malaga heaters, and i have no idea how they work
    but- i know that they don't mind a bit of a clean with a bit of wet and dry, and i also know that the burners are notorious for rusting away, which can cause rust flakes or poor contact for sparker and t/couple, so best clean to bright metal and blow out any rust debris .
    luckily you can do this kind of maintenance by removing the outer vent cover, then the ally plate which is held by 2 screws.
    if the burner is rusted out you can get them on ebay- but they're dear !

    Carver Cascade Rapid now working.

    I will tell you what I did to get water heater working on gas because I am feeling rather smug tonight. I removed the two screws holding the burner assembly in place slid the burner assembly out. The actual burner was very rusty so I cleaned up all the outside with a wire brush in the Dremmel the centre hole in the burner I found a piece of dowl slightly smaller than the dia of the hole wrapped a piece of emery round the dowl and cleared all the rust from the inside. I then removed the main jet by unscrewing it it was quite difficult because it had thread sealer on it. I then got a piece of wire the same dia as the hole in the jet at the threaded end. I tried to push this through the hole in the jet from the threaded end it wouldnt go through the last little bit of the jet. So I worked it backwards and forwards until it went through easily. I then reassembled everything and pressed the start button it fired up with a much stronger flame and worked perfectly, I should add that before it was igniting and going out after 8 secs.
