Our combi boiler sounds like a fog horn

[Paul Lake's Left Knee]

I would adopt the Malcolm Tucker response to how to fix a paper jam but it can be used for a boiler as well...

Way-Hey, the return of a boiler thread, it's been a while. Who says global warming is a myth..

 

[s1ty m]

Ever since we moved in it's occasionally done this every few hours or so. This last week has been fucking unbearable, we've even had to turn the heating off at night because it was keeping us and the neighbours up.
We had our yearly gas check and boiler service earlier in the week and we mentioned it the blokes who didn't have a clue and wasn't that fucking interested tbh.
When it goes off, it lasts for anything from a couple of seconds to almost a minute. I'm hope the plumbing and heating gurus on bm can identify the problem, and no, I don't know what make of boiler it is.
It's going off about 3 times an hour. On the plus side, at least when it's foggy we would be safe from passing oil tankers, even if we are about 60 fucking miles inland.

I might need some water adding in to the system. Is there a tap near the boiler that is for this purpose? Ours does this occasionally and the engineer who came to look at it just added some water and it stopped. That said, I'm still a bit puzzled where the water went...evaporation?

It's a combi boiler on the mains water supply. How could it need water adding?

If turning down the boiler stat has made it worse, that's baffling - to reach a higher cut-off temperature the boiler would have had to be on longer than at lower, so why it should make the noise more is strange (but then so's the noise). Very odd.

Brick its windows, set it on fire and then shag its sister

Could it possibly be something as simple as a pipe that isn't secured properly and it's vibrating. We had this in work and it was incredibly loud.

I was going to say this last night but if you say you had a plumber out then surely he would have checked for something so basic?

Wow, what a coincidence, my boiler has just gone on the blink!!!

It is a top of the range Worcester Bosch floor standing model. It had a fancy display on the front that tells you everything the boiler is doing etc.

The boiler suddenly stopped working and the display is saying "The D5 condensate pump float sensor is faulty-----replace part number 875477654 to rectify fault"
........any "experts" on here know what on earth the fault could be. The display is a bit vague etc.

It sounds like there's a fault on the pump float sensor

Haha, the water, gurgling noise sounds like it's repressurizing?

 

[remember arthur mann]

When they came and serviced the boiler he turned down the temp on the boiler and said it might make a difference. Tbf it has, it's made it worse.

Stop employing cowboys !

Cheers Andyhinch. Deleted the post as it's working now. It was a bit tongue in cheek as to the fault code. I think even people on here would have figured that one out!
A quick kick must have freed the condensate pump float switch.
Once the condensate cleared, the boiler fired back up. It is a few weeks overdue it's annual service, so i will mention this when they come...

Sounds like it was just sticking on constantly resetting itself, things like that tend to confuse the shit out of themselves, Stonys sounds like an air blockage in the system causing cavitation

 

[york away to this!]

Your boiler is haunted. Have a seance to establish the problem.

 

[kaz7]

Have you tried switching it off and on again

 

[Dave Ewing's Back 'eader]

Impossible mate. Curry is banned in my house.

I could accept the invite for afternoon tea, then Stony! I don't want a lot sugary stuff either!

Had this problem a few years ago it turn out to just be a loop pipe or something not fitted properly, plumber sorted it easily

 

[stony]

Cheers for all the replies. I'm still waiting for Bodgit and Scarper to call me back. Useless twats.

 

[quiet_riot]

I seem to recall our old house did this when you opened a tap very quickly - turned out a new stop-tap (outside) sorted it.

 

[i kne albert davy]

Maybe fan bearings on way out mate if its intermittent.

 

[Tuearts right boot]

First thing's first. You need to check that the Sky dish on the roof isn't in fact an actual fog horn and you live overlooking the storm battered North Yorkshire coast.
