What makes a chicken coop easy to live with?

[Bramble]

Hello! My heating has packed up, I'm freezing and can't get a plumber! I don't suppose anyone knows how I can fix "Error 125" on this system, by any chance? All replies gratefully received, thank you!

It's a component fault according to the instructions - so you'll need a plumber I'm afraid

Don't forget to mention the code when you book them, and stay warm til then. Will British Gas not come out?

[Bramble]

Thank you aunty e, that's what my manual said, but i'd hoped there might be a magic fix!! Im still trying to get through to BG - thank you so much for your reply!

When my boiler stopped working a few years ago, i called British Gas, but had to sign up to the annual service scheme,( It was cheaper than paying for the call out fee and parts ) and the man was out the next morning.......glad i did as the new fan he fitted cost a fortune and i didn't pay any extra except the 12pds mth for the service.....stayed with them and get my annual check up.

[Bramble]

Thank you Angie and Auntie E - your support has been very much appreciated (and all the other Omleteers who I know have read the post, it's good to know you are there!)

Well, I couldn't get through to BG, they say they are massively busy due to the weather, so I thought I'd try to reset the boiler (I know, I shouldn't mess, but I thought it had to be worth a try). The first reset just resulted in "Error 131" (which isn't in the manual) a different error message from the first one, but an error nonetheless and I still had no heating, so I tried again ... and this time (she says, whispering, with fingers crossed, touching wood etc) it's worked, the radiators are heating up! No idea what the problem is, I'm just hoping it's sorted itself.

Thank you so much everyone.

Glad you now have heat ! Hubby cracked a radiator pipe this evening (major decorating work and the pipes were sticking out of the floor waiting for the plumber to move them). He's managed to seal it with gaffer tape so we didn't have to drain down the system but we daren't have the heating on

 

I am so glad I got a woodburning stove last year I'll have to make sure I keep that stoked up all day tomorrow.

hubby is a plumber this is what the codes means

 

e 125 circulation fault could be faulty pump or and ice blocking a pipe

e 133 flame failure

My boiler conked out this morning and it was due to the condenser pipes outside being frozen, even though they were lagged. A kettle or two of hot water sorted them (and a son who is a plumber) and we are leaving it on overnight now, in the hope that it will keep things moving. Perhaps yours is/was similar. Glad its working now.

[Bramble]

Thank you everyone, I can't tell you what a difference your support makes, the only downside to living alone (apart from chucks, dog, fish etc) is that when something goes wrong I'm on my own! Anyway, as Egluntyne suggested, I kept the heating on overnight and (again touching wood, with fingers crossed and whispering very quietly), it is still going this morning.

Thank you to all!

[WitchHazel]

bramble, is it a condensing boiler?

 

if so, take note of Egluntyne's pos

This was a really common problem last year, and plumbers all over the country were making a fortune on call outs where that was all that was needed. You need to work out where the pipes go outside, and the check them.

 

If it's not a condensing boiler, then I have no idea how to resolve the problem.

[Bramble]

Thank you so much WitchHazel, yes, it is a condensing boiler, think I've worked out where the pipe is (at least I'm assuming it's the short pipe that's on the outside of the wall near to where the boilers on the inside, if you know what I mean). I've definitely made a note of egluntyne's tip - that's definitely one to add to the manual! The pipe doesn't look frozen, but who knows. I'm just wondering if leaving the heating on 24/7 would stop that pipe freezing?

[Aunty e]

Don't do that! Lag it with some of that foam pipe lagging! Our gasman warned us about that last year, and we did the same and have had no problems thus far, even though chook water has been freezing left right and centre.

[Bramble]

I have looked 'ont internet to check if the pipe I think is the condensate pipe actually is, but I don't think it is. Descriptions all say it will be a white plastic pipe which goes down to a drain etc. The only external pipe is a brass/metal pipe, I suppose about 4-6" long (and probably about 1/2" diameter) which comes out of the wall by the boiler and then bends at a right angle, but as far as I can see, it doesn't go anywhere so I wonder if this is just a vent? I'll lag it anyway, but don't think it's the condensate pipe ... ? Guess I'll just call BG (or try) if it happens again?

Very grateful for all the replies ... thanks everyone

[Steve the Gas]

Bramble the pipe you describe is the PRV- Pressure Release Valve, this terminates outside to release any over -pressure beyond 3 bar nominally.

The condensate is plastic and should terminate into a 'foul' drain. The latest recomendation is that externally that this should be in at least 32mm diameter, but I would bet yours is 19.5 or 22mm. If so lag it asap - as suggested. Sacking works if you have it.

 

What pressure is the guage reading on your boiler please- I may be of some help................... clue is in the name

Thank you! I've found the condensate pipe, I think, it's white and plastic and goes below the boiler into the drain under the sink, so it isn't frozen. The pressure is just about on two (bar?) well sort of half way between one and two really, but it's well within the green section, if that helps?

[Steve the Gas]

That all sounds good then.

The error codes can happen from time to time, merely requiring a reset- for no apparent reason. If it's not been serviced within a year - I would suggest you do.

[Bramble]

Thank you very much, Steve, I am organising a service, so we'll see what happens. Thank you for your help, it's happened again so am trying to get hold of British Gas (again!). Very grateful for your help, shame you're not closer, or I'd book you!!!!!!! Thanks again

[Steve the Gas]

You're welcome as is anyone on here

[The Dogmother]

You're welcome as is anyone on here

 

you might live to regret that Steve!

[Angie]

Haha!!!! Steve the plumber/boilerman.....you're a marked man now.....

[Steve the Gas]

 

Bring it on..................

[Bramble]

HELP!!!!!!!!!!!!! It's happened again! Seems to be when I turn the thermostat up, the boiler's still running but the radiators don't heat up and I get "Error 125". BG came out yesterday and said they couldn't find a fault (except one valve which the chap said wasn't seated quite right or something, he dealt with that, but thought it probably wasn't the problem), so I've just 'phoned them again and they say they can't come out again until next Thursday!!!! Have reset the boiler and it's running again for the time being, but wonder if there's anything else I can do? SOOOOOOOOOO fed up.

 

Any ideas very gratefully received ... thanks

[Steve the Gas]

Have you got a leaking hot tap............... and I mean a drip?

 

Pottys have very sensitive diverter valves. Therefore, any drip will make the boiler go into hot water mode rather than CH.

 

Any other info you have may be useful too.

[Bramble]

Hi Steve the Gas, I didn't dare hope that you would read my post! No, as far as I know, none of the taps are leaking/dripping, they are all mixer taps, if that makes any difference?

I've tried bleeding all the radiators, they seemed fine - no air. All the radiators (except one) have those valves on them (thermostat valves?), a couple are turned down lowish (eg the spare room, which is empty at the moment). I've just been round and turned them all up so they're all on roughly the same setting, might having them on different settings cause the problem (I thought that's what those valves are for?).

The system (and house) is about 2.5 years old.

The manual says E125 is a circulation problem (but I'm guessing you already know that!!).

The problem seems to come when I turn the main thermostat up (having left the heating on very low when out)

Can't think of anything else to tell you, sorry, but completely I'm clueless about this kind of thing.

Thanks Steve!!

[Steve the Gas]

Any rooms you are not using - turn the TRVs to minimum.

This will push any heat into the other rads. If you have a problem rad, come back and let me know.

The circulation prob - could be the pump is sticking and starting to die. If you can there is a large (size of a 10p piece) screw in the middle of the pump head. Undo this screw - there will be a dribble of water but not much - use a ragg or 2.

Check to see if the pump is turning - you will be able to see the shaft. This shaft has a screwdriver slot in the end. Turn the shaft with screwdriver - this may help for a few days....

If it is the pump, it will eventually die.

Pm me as I missed this post yesterday- soz.
