Hi,
Recently our combi boiler started turning itself off randomly (the pilot light kept going out) and although we can reignite it immediately it isnt long before it goes out again. This happens when the central heating is on, and most often if we run the hot tap while the heating is on. However we can run the hot water with the heating off and the boiler works fine.
We called out an engineer and he said it was being caused by our mixer shower not allowing enough water through which was causing limescale. When he left though the boiler worked fine for a month, but now its started switching off again when the heating is on.
So I have a couple of questions:
1. Is the engineer right? I fail to see how the shower can be causing this, when it is the central heating that causes the problem. We can run the shower without the heating fine, same as the hot taps. Also, the problem reoccured this morning BEFORE the shower had been run.
2. If its not the shower, what could it be?
The pressure gauge seems fine, the red arrow is in the centre of the green area, and the black area is about a third of the way into the green.
I would be grateful for any help, I am going to call for an engineer again, but I'd like a second opinion from someone.
Thanks,
Luke.
