Hi all,
#
I have had an Ideal Isar HE30 combi boiler for about 5 years, haven’t had any major problems with it so far but I have replaced the fire detect electrode and the spark electrode few months back. A few days ago it started to make a noise that sounds like its struggling, when the hot water is running. The boiler starts up as normal, burner comes on and there's hot water, but a minutes later the water starts to get cooler and the boiler starts to make the struggling sound and then the burner would stop. A minute later the burner starts up again, and the same cycle continues. Normally the burner would be on as long as there’s demand for the hot water. However the boiler runs fine when in central heating mode. I have had the boiler serviced by British Gas recently. I am an Electrical Engineer by trade and tried to figure this out but haven’t had much luck as i don’t really know that much about boilers. The pump and the diverter valve are working as normal too. It seems like the sound is coming from the heat exchanger. Anyone able to give me any helpful suggestions? I would be very grateful...

What was the outcome of this problem mate, i have exactly the same breakdown and I suspect the DHW sensor. I'd like to know what happened on this job if you would please mate

the point of you having a yellow badge rory is you ask in the gsr section and as this was last posted in 2011 i suspect the op has bought a better boiler by now THREAD CLOSED
