The heating system is fine but the boiler doesn't work correctly driving an Aqualisa Quartz digital shower installed about 6 months ago.In the morning I have to get the heating going before I get any hot water out of the shower. Even then the shower is not hot enough and the blue light continues fllashing. If I turn off the shower I get hot water out of the tap. Any ideas please on what the problem might be ?
