broken boiler after last night's rain

vegas07

after the torrential downpours last night, the boiler has gone on the blink!!

the 'exhaust malfunction' light has come on..... so we're thinking a load of water has gone in the flu (is this a possibility?)

so, does it sound like i need a professional to help me out OR what are the chances of it drying out overnight and the boiler working in the morning (guessing slim, but living in hope!)

also, if i need to get someone out is it worth signing up to BG homecare and doing a call out through them?

thanks in advance for any advice or ideas,
Rach

It sounds as though something is obstructing the flue. Is it vertical or horizontal? Has anything been like moss, lichen or leaves been washed in or over the discharge perhaps? I think it unlikely to be just water. Last winter I had a problem with a bird roosting in the flue outlet which meant the boiler would work in the daylight hours but not at night. I think if you sign up to a maintenance contract they will not do anything for the first 28 days.

This could very easily be water in the flue, I have had it 3 times before in other houses.
It does not have to be an incorrectly installed flue as some will say, as the rain can sometimes travel horizontally.

It soaked the fan which then burnt out, so I had to replace it each time.
(although I actually rewound the coil instead).

You should get a gas safe registered engineer to look at it.

Although bg's fixed price repairs may be cheaper.
(watch out for them condemning it just so you buy a new one from them).
