Mira excel shower assembley

I have a Mira Excel, which was fitted around 1991, which is fitted with a power shower pump. The temprature has suddenly gone haywire, in that it goes red hot and then cold, but it works ok with out the power shower although the temprature number has to be almost at its highest. I have cleaned out the filters as you have said to somebody else and the power pump is working ok. I am thinking that the cartridge needs replacing I see that there ar two Post 1990 models. On pieces of paper in the assembly there are numbers F230 764 and 06 1804, but cannot find these on your parts list, help please!!
