Hi,
I came back from a week’s holiday on Sunday to find the boiler not working. It wasn’t working on either hot water or central heating.
In diagnostic mode the LED’s would sometimes just show a fast flash on LED 1 (‘Faulty boiler or irregular operation’) or alternatively LED 1 and 3 would flash normally with LED 2 Red on constantly (‘Lack of burner ignition’). I noticed the lockout light also came on the last few times I tested it but I’m not sure if this was coming on any of the other times I was testing.
It didn’t sound as if it was even attempting to ignite. I had a similar (but intermittent) problem last year but that time you could hear regular clicking as if it was trying to ignite. This was resolved by replacing the Ignition PCB.
I followed some advice on another post to check the water pump. It sounded as if it was running but I couldn’t be sure. When I took the middle screw out the first bit of water that dripped out looked pretty dirty - is this normal or could it indicate something wrong?
One of the other bits of advice to check whether the pump was working was to put a compass near the pump. I didn’t have one to hand so thought I might be able to feel it with a magnet. I put the magnet near the pump when it was on, it made a little bit of a funny noise and then the boiler started up. Now I’m not sure if it was by sheer coincidence or if by putting the magnet near the pump it somehow freed it slightly so it could spin freely (I can’t imagine it would have been strong enough but who knows). Is this likely or am I grasping at straws?
The boiler fired up fine last night and this morning but I’m worried I didn’t really get to the root cause of the problem and may just stop working again anytime soon. Is there anything else I can do to check?
Thanks in advance,
Mark
