the hw works fine on my combi boiler but the ch starts for a few seconds then switches off , wait for about ten minutes then the same happens again or when it eventually comes on it has a mind of its own
common pcb faults on these had 3 of these boilers in my friend rented house and 2 of them developed this fault of turn the boiler off then on heating comes on then nothing for a while then fires up then off again drove the tenants mad i would advise you change the boiler as u will have problems very soon again with this boiler as they have alot of common problems gas valves pcb leaking diverter valves overheatstats i can go on and on

I know this sounds silly, but do you have a room thermostat? If so, is it turned up sufficiently? It's still pretty warm right now 20c may not be enough to fire the boiler properly.
