Please can u tell me how I get the fitted toilet to work as when I push the blue button on top of toilet to flush it won't work.
It could be that the fuse has blown and needs replacing. The fuse is normally located inside the box where the waste cassette is housed. If you open the cassette locker and remove the cassette, the fuse should be located at the back near the top. Once you have found the fuse holder, remove and change the fuse. Hopefully the toilet should now work.
