I have a Biasi 24S gas combi boiler. It was working fine until tried to have a shower this morning and there was no hot water. The furnace ignites when the heating is turned on but nothing happens when the hot water tap is opened. I've tried running the tap with the heating on, the radiators heat up but the water stays cold. Temperature and pressure gauges are fine and there is definitely gas going in. I don't understand, please help!
