Hot Water Problem Saunier Duval 30e?

I have to close down hot water tap on bath to a trickle for hot water. Any faster flow results in luke warm bath. Boiler continually lights closes down and relights on about a 30 second cycle. Problem seems to be getting steadily worse over time.

I have sound plumbing, not gas, and electrical abilities and would like to learn more about the sytem if this helps. Any pointers would be appreciated.

Hi, you'll probably find it's due to a rubber diaphram the size of a of baked bean can lid. As time passes, it starts to perish which results in the pressure dropping which'll stop the bolier firing up. They're extremely cheap to replace.
