Carver Cascade 2 Water Heater in an Autosleeper Duetto Motorhome 

My burner has become very noisy and I'm convinced the burner needs a good clean. Now I know how to to do it. Great video thanks

Brian, I feel I owe you a beer, send me some details, and I will in receipt send you some. I have spent many an hour trying to measure the rectification element created by the flame, cleaning the burner, and even cleaning out the jet, without ever having removing the jet. Removing the jet uncovered debris, and loosening the burner unit so I could adjust the distance between the jet and the orifice on the burner has just saved me a small fortune. I really didn't realise the jet could be separated! Thank you so much.

After 22 years my burner is very rusty and flaky - this post has give me the confidence to replace the burner - thanks for posting

Wow. I’m surprised I haven’t seen this video before as I’ve had to fix my Cascade a couple of times for other reasons. Really well presented and it’s nice to see someone including technical explanations whilst keeping the ‘how to’ aspects simple. Good Stuff.

Just fixed mine,water in the plastic tray under the pcp board. The solder seems to have been jutting down under the board a touch the water ,also the plastic enclosure was being clamped by the heater casting,so clamping the plastic enclosure. just filed the casting now able to withdraw the unit from the side,and no clamping problems on the electronics. Every thing now works,this video was a great help. Many thanks.

Thank you Brian, very informative and covers the points needed 👍

Thank you sir ,it was really useful, two weeks ago i brought a caravan and i have no idea what it is , there was not any wiring and instruction. thanks for sharing...

What an excellent presentation! We have a caraver rapide., and your video has been so very educational. Please tell your family that you are appreciated and doing a marvellous job. Regards from New Zealand.

Brian, I haven't fixed my cascade yet but am convinced you've just shown me how to do it. Many thanks for posting this very helpful video.

Very well explained and clear video. Very clever guy. Thank you.

Many thanks found the problem with mine .. it was an internal glass fuse gone in the igniter unit great video 👍

excellent instructional video thank you for recording and posting. I now have complete confidence to troubleshoot and recondition my Cascade 2 . Thank you very much

Just fixed my son's Water heater. Many thanks: It gave us the confidence to try it.

Excellent explanation of how the Caver cascade 2 works, especially the flame detection part. I need to replace the burner box as mine has rusted out through it not being used for many years. Thanks Brian ! Great job !

Thank you so much! This helped me solve what could have been, if taken into a shop, much more costly. A clear and concise video

A well explained video and having the electrical side explained helped . excellent narration ..well done

Brian, Thanks so much for that. I am having the same problem. as i live in New Zealand and own an otherwise excellent English caravan I have been at a loss. i have asked various 'van sales and repair firms here on how to rectify this annoying problem. not surprisingly they are all reluctant to share the process you have described. they of course either want to do the job themselves or sell me a brand new module at a king's ransom price. You have helped enormously. Cheers, Roger T. (one grateful Kiwi)

Fantastic video explaining everything clearly. Great job.

Had same issue. Took apart cleaned and test running like a dream. Many thanks for your video

Brian . . . Brilliant video. I am attempting to rebuild a Motorhome and this will certainly help. Thanks Geoff

Thank you for this detailed video!! I was looking on how to remove the burner and this answered all my questions. Much appreciated!!!

I can confirm, this worked for me! Pull it out, give it a good clean 😊

I had the same problem. It was caused by corrosion deposits from the alloy casing covering the burner. Cleaned them out and rubbed down the casing and sprayed with stove black paint. The screws for the stainless panel behind the burner sheared off on removal. I fitted a jubilee clip on the drain plug pipe to keep the panel secure.

Thank you SO much! Just replaced a gas only with a gas and electric. Got EXACTLY this 8 second problem Hopefully your solution will work for me as well Thanks again

Excellent Video and well explained. Thank you Brian, Regards Adrian

Thank you very much for this video. It will help me to solve a similar problem on my son's Camper

Very clear and detailed. Thank you.

Worked a treat. Thanks again

Well made descriptive video and very clear photography too. I looked at primarily for the "how to remove" bit as my burner needs renovating. Would have liked to see the "difficult to see" screws holding the gas valve in......maybe some white arrows pointing to their location?!!

Thanks Brian your video was really helpful. Mark

Thank you very much for this. ❤🎉

many thanks for sharing. we have a 1991 caravan and the water heater didnt work and was just to pricey to replace followed your steps and hey presto we now have hot water.

Nice fix Brian.

Very informative. Many thanks.

Thanks Brian, useful video.

Excellent even from a gas engineer

thanks for video, very useful, robin

Thank you.. great help!!

excellent video!!!

Amazing thanks for the help

I have an Abbey Oxford only on gas, no 2eg electric boiler. I am from Romania. I have all I need, even the leak is fixed from the tank, I have flame, but no hot water. I think this is the same problem you have, since its 1989 built. Thank you I will try to clean it too !

Top job Brian and thanks for a clear and well made film. What a difference in flame size! It must have been a bit slow to heat up in the period before it failed? I'll be ready for that one!

Hi Brian great video very helpful ,i have one of these that is leaking water (external) from the nut looking thing in the middle of the heat exchanger fins (center of) any ideas.thanks

thank you it is a valuable information

Well done!!

Cheers for this!

Really good, thanks

Very helpful thanks for time

We have a 1980s Mercedes 207d motorhome we have used the shower with hot water via the 12v battery worked well now wanting to use it on gas to heat water for showering I turned the gas on then I put the switch on inside the van then put the carver switch on which stayed on green left it on for 45minutes tried Water freezing cold so then left it for 4 hours tank is full of water by the way still cold my unit outside is sealed up around the edges so I need to cut the old seal off unscrew the screws and have a look inside as I can’t really see inside with out taking off the front cover hoping your video will help me sort this issue out as it will be much easier heating water on the gas bottle while we wild camp any advice would be great

great help thanks alot :)

Thanks great help .

hi, can you tell me where the main waterfeed go's into the cascade 2, i built a campervan 2 yrs ago and never bothered connecting it up, theres two pipe connections on the back of it on the right side, i have cold and hot pipes run up beside it from the sinkl but where is the feed from the watertank and pump go too? thanks, Paul

I have this same Water Heater, but for some reason no lights come on the control panel at all, either when Leisure battery or hooked up to the mains, My Volt meter confirmed that power from the Leisure battery was getting to the panel, but still not lights, cant work out what i am missing

I have a problem with actually removing the assembly, the bit that occurs at approx 2mins 25secs into the video.Its loose but the box inside seems to big to come through the hole. Any suggestions

I done the same, Thanks Brian. I do have a problem though... Instead of shutting off,, the burner stays on for a minute, then shuts off for around 1.5 mins, then starts up again, This continues in this manner, not heating the water. Left in this mode for 2 hours, water not even luke warm, Any ideas ?

cool thanks for that

on my spark electrode the porcelain is cracked and broken, will it still work?
