Webasto water heater

Having problems with our Webasto water heater, the cabin heater works but not the water heater, I looked at the troubleshooter and it says to locate the reset button but I can't find it, any ideas please

II work on certain models of webasto heaters what model is yours

I,ve got a Cotswold with the Webasto heating and will almost certainly be the same as yours. I have done a lot of research  etc on the system which is really good now I understand it all in quite a lot of detail. I had a new control panel as it would not operate the dump valve.
Very  easy to replace.
However I have spoken to the following who are the UK dealers for Webasto and are very very very helpful. Will explain whatever you need to know.
They are Butler Technik (sorry if you are already aware of them),
ask to speak with Steve Winter. Tel number 01427 787121
Really helpful. I have also spoken to a chap called Paul at Webasto UK tel 01302 381145. Another very helpful chap.
As I said I have come to know the system well so if I can help further please let me know.
I can,t help with a reset button, did not know there was one but it will re set if you remove the 3 fuses in a particular order and replace them in the opposite order. They will probably be on top of the leisure battery under the seat. I can let you know the order but I think it is in the handbook. (or did I get the info from the above person, can,t remember)
PS When you say the water heating does not work are you trying it on electric or diesel or both

PS. If all else fails ask them for your nearest accredited dealer, they will have a diagnostic computer thingy much like a car diagnostics and it will give pretty much the history of what problems its had in the past if any as well as the current problem
From Webasto website it looks as though your nearest dual top certified installer is RVS engineering at Cardiff

I don't work on the duel top but the other heaters will reset if you disconnect it from the power supply for a few minutes.

Yes I agree as I said pull the 3 fuses in a specific order. This disconnects all the circuits to the heater for a re set

Thanks everyone, I did the fuse thing and it started working again, however on our last trip, this last weekend, the heating wouldn't work again. We did the fuse procedure but it kept showing Error 01 and wouldn't reset or work on any setting. I may be being stupid but the only thing I did different was that I filled the water tank and there was a leak underneath the van, which I assumed was an overflow, would this have caused this error?
