Hi I am new here and require a little advice regarding my Ferroli combi boiler. It is about 7 years old now, up until recently it worked fine, I would come in set the thermostat or turn on the hot tap and hear the boiler light ignite and hear/feel hot water being supplied. Recently however the boiler light has not been automatically igniting and I have had to constantly tun off/on/reset for the flame to ignite and supply hot water. Sometimes I have to do this 7 or 8 times as the flame cuts out again within 10 seconds. Can anyone advise me as to what the problem may be ? Thanks in advance, Johnny.
