Combi/shower problem

My mother?s shower is playing up. Apparently it has taken to starting off fine but then going cold after a couple of minutes. I went up and had a look and as far as I can make out, the boiler seems to be behaving normally when you run a hot tap. Even at relatively low flows it kicks in and starts heating the water. The problem only happens with the shower. It?s been looked at by a plumber who hasn?t been able to fix it, all he?s done is to crank the boiler temp up to max. I?ve tried turning it back down but this hasn?t helped apparently. I don?t know what kind of mixer valve the shower has (whether thermostatic or pressure balancing) but irrespective of this, it *used* to work fine and now doesn?t. The shower head is clear and there are no obvious obstructions. Any thoughts? My mother is getting rather fed up with it. Tim

Very probably but as it?s only 5 years old, I don?t think my mother would fall for it. ;-)

As an aside - why do we expect someone who was trained to install and connect pipes to be the ideal person to fix a boiler? The skills or aptitude is more akin to a washing machine technician.

Logic and control system architecture seems to defeat most plumbers.
