hi, hope you help,having one or two problems with the combi boiler,basically sometimes its fine & othe time it wont fire up or sometimes just goes off automatically(ie no burner ignited) & then it takes a while to start it back up,but if you give it 5 mins by switching the boiler off & then restart it can be fine for a couple of days . when it has switched off before & you reignite the burnes you can here it starting ip (i presume thats the pump) but it doesnt go to the igniter stage,but switch off for 5 mins & you here the first sound then switch on the radiator & you can here the burner kick in straitaway,any ideas? my normal engineer is on hols in dubai for another 3 weeks. thanks again
