Was wondering whether anyone can help as 2 corgi registered plumbers can't! My boiler is an ideal mini 32 and is approximately 5 years old. It clicks the fan on and off and occasionally fires the boiler about 10 times a minute. It now won't fire for central heating which is great seeing as winter is coming. It had a new diverter valve fitted as it was heating the radiators when asking for central heating but also leaking water out of the over flow off the pressure release valve. I have had two corgi registered plumbers out and they can't find anything wrong with it, one thought that the clock/timer was knackered but there is nothing set in it. Does anyone have any ideas it would be much appreciated
