My hot water and central heating Combi will only run for about 3 secs, even after a system reset or power off. When I turn on the tap, the boiler runs, fires up, produces a few seconds of hot water, then turns off. Same with the heating. A reset gets me another few seconds!
Water pressure is OK. The boiler is a Ferroli Domina.
Any idea what the problem is? Can I do anything to work round it in the short term?
Thanks Tim
