having problems with my ferroli f30 combination boiler,when running in central heating mode.once it gets up to temperature it cuts out completely with out the pump running on till the next time the boiler fires up.then it just keeps firing up about every 5mins for about 2min and shutting totaly of again repeating this prosses over and over again and as i said the pump doesn't run on. i've taken out any remote controls for the system,but that makes no odds.its seems to me that when it fires back up it reaches a temperature causing it to shut down,just after some ideas if anybodys got any on this problem,thanks
