I was wondering if you could help me, I have a Ariston MicroCombi 23/27 MFFI in my flat which is great; giving hot water through the taps, great heating but since 4 weeks ago has only been giving luke warm water for the power shower. I have tried a number of things but not tampered under the cover of the boiler, can you help?

Needing a hot shower!
