Noticed there was no hot water so checked the boiler and its really struggling like a pump is failing?

I replaced the PCB 18 months ago and no problems or noise since.

Any ideas? Obviously pretty urgent given the weather :eek:

The failing noise is coming from the boiler itself, its a closed system with an expansion vessel.

I've turned the pump up from 1 to 3 and at least its running but its bl00dy noisy making a screeming noise? - edit: just to be clear I don't know what the part is in the boiler that's making the noise but it sounds like a pump. The central heating pump near the 3 way valve is what I turned up to 3 and its running like a champ :)

There is no pump in the boiler case! as said if noise is coming from the boiler then FAN is the likely culprit :rolleyes:

ok I may have got that wrong if a couple of resets were what actually got it going. So if its the fan can I give it a knock to get it going and can I replace tomorrow morning DIY?

Atm its basically not running and so I guess the boiler is auto shutting off :(

The boiler is overdue a service by 6 months, is it possible that's caused the problem or would the fan have died?

Can I open the cover and bang it with a hammer?!!!

Cheers

This may seem a bit obvious (and it does sound like a faulty fan), but you have checked the system pressure havent you?

guessing is right. if the boiler itself is screaming , the likely hood is the fan.

but

this involves entering the combustion chamber and replacing the fan can have an effect on the safe operation of the boiler. coupled with your mention of an overdue service, why not get a fixed price repair from the big company and have the safety checks carried out at the same time?

fair point gavinda, accepted. I will get the service in. But for now I have the fan out and I think it just needs some lubrication on the spindle/axle. How can I do this? The part I found for replacement on ebay looks like its HE only as it doesn't have the back plate so I may not be able to get a replacement part today, although will probably pop down to plumbers merchant just in case they have one, get some coal on the way :)

The plumbers merchant had one in stock, so I've fitted that and all good. Have a CO1 alarm on the boiler so will leave it it there and book a service - cheers fellas - toasty :)
