Thetford C3 water inlet valve

I need to replace the electric valve on my C3 unit but I cant see the part looking in through where the cassette is housed. Am I correct in assuming I will have to remove the back panel to get at it, or does the whole lot have to come out? Anyone had to replace one of these before?

Ok found it lurking under the tissue holder, talking to myself again
