I first discovered about the venturis breaking at 4 oclock on a friday, luckily partscenter was nearby and had one in stock. live and learn all the time

 

[Billy Bob Bob]

bet you keep them in stock now old plumb, thermistors (white end) dont stay in stock with me long either,the likes of B.E.S ans antares sell these in packs of 10 but the venturies are a even bigger seller

Quick update guys, I didn't get to this job again today as i had priority stuff come in (there central heating is still working after all!) 🙂

I bought the venturis, as well as APS, and high limit stat. I also spoke to Ferroli who seemed dead certain it was a blocked heat exchanger.

I'm going back tommorow to start trying things, starting with stat and venturis. I will as promised bring this thread to a conclusion so it might be helpful to other people in the future.

My phone just didn't stop ringing today. Its a love hate thing!

 

[Dannypipe]

Right, said I would bring this to a conclusion so I will! First pic is new part fitted in fan.

The boiler did run properly with the cover of. So I took the fan off, looked at the venturi, and visually what i could see looked fine. However I thought I'd remove it to get a proper look at it. The picture of the red crumbled thing is what happened!!

It had the texture of egg shell and fell apart. (Why don't they make them from metal?)

So I fitted the new one, and pushed the cover on, it tried running the hot tap, and it was consistently hot. Problem solved!!

The boiler still cycles during heating only, think this could be that it's so over sized....as I mentioned.

Big thanks to all who commented and I believe it was Gas Man that first mentioned the venturi, so double thanks to you. Client pleased as they don't have much cash and it was a cheap repair and a cheap component.

I injected some F5 into the system as they have a bathroom fitter there at the moment and he says he's happy to drain the system and put the inhibitor in it. The water is as black as the night. So I wonder if there is a slight blockage in the HE?

Anyway, they're happy, I'm happy, you're happy. Everyones happy!!

Danny

glad it worked out danny,a very weak part on all ferroli modenas and f30 f24,and my first suspect when i come across this fault if the waters black ch thermistor will not be long before it gives up,thats what this forums all about helping each other

 

[stevetheplumber]

it does not have a plate heat steve

that would rule that out then

i agree with that sentiment gasman a lot of us dont get many boiler repairs and dont gain that depth of knoledge its great to have the means to tap in to others experience
some one should start a web site with the top five problems on popular boilers
actually the boiler manufacturers have access to the most common faults long before anyone else and should be forced to list them on their websites

 

[Billy Bob Bob]

i totally agree steve,about helping each other,what really winds me up is the manufactures,look at this thread from danny as a example ferroli were adamant it was the heat exchanger cost to buy £350 (twinpass so dear) and as i said it would be the venturies but they wont willingly give out the right advice because they want to rip you on spares,in this case danny would have more than likely replaced the boiler,so this forums invaluable

 

[Dannypipe]

True, client was saying that they would rather have a new boiler than put a £360+VAT part (PTS trade price?) in there boiler. I don't blame them. So a tenner on a component is a winner all round. I like to repair things, and not throw something thats perfectly good in the skip.

Also as I have said, why do they make the part from plastic? it looks like something from a Kinder Egg.

Its a good forum, and I come on here to help people and learn....so I now have this info saved in my noggin for the next time.

It kind of annoys me when people come on for advise and you get no feedback as to if it worked....fine if it didnt but if it did it's useful to post a quick message as it means the thread is available for others in the future.

I've used threads that are 3/4 years old in the past to get me out of a jam with all matter of things from boilers to laptops.

 

[Billy Bob Bob]

thank you for the feedback Danny,always appreciated to all of us on the forum,and i agree with what you say but people are people 2 pm,s this week thanking me for my help but last week none,we give advice for several reasons to help guys like us out,as you have asked and very capably sorted out,and( i may need your advice one day)and to help others(when we think they wont kill them selves)as it was pointed out to me the other day,this forum is growing and is already good but we dont settle for that on here we are the best,and if we cant ask each other(which we could not without the forum,could in the merchants but most are miserable gits) whats the point of the word colleague ?we are all learning all the time

My son repaired his ferroli fan motor circuit board £10 for part from electrical wholesaler.
Ordered part then told the order was cancled. So ordered board £170 next day delivery,
still needed another part £90 . Called in plumbco New ferrolli Boiler £320 how do they do it for that I asked , they make more money on parts.

 

[ifgw77]

Hi All, I'm having the exact same problem; I believe it to be crap in the system. I was just wondering if anyone had the exchanger out on one for the best way to do it.
Thanks and Kind Regards, Ian

 

[plum.bob]

Hi, just wanted to say big thanks all you guys who take time to reply to these threds.
To Dannypipe, i had the same simptoms as you described. Beenscratching my head trying to figure it out, read this, done it, fixed it, customer well happy, and so am I at the gained knowledge.
Several plumbers just said replace fan/ heat exchanger/ circuit board and so on, others just said replace the boiler first as last.
Gas man your knoledge nows no bounds, many thanks.
Theres allways another way.

 

[glenfruin]

I would like to thank all that posted on here as I had they same problem with my boiler....i,m not a plumber but i used the advice and opened up the boiler and carefully vaccumed out the venturi and any other little hoses and pipes.then reassembled and it works perfectly now.no new parts req 🙂 thanks again

Balls. missed this one. moved to private forum.

Keep an eye out lad, stop these cretins using info off the forums where they shouldn't!

 

[Killy Bing]

Tut tut

 

[Killy Bing]

This thread isnt exactly for public eyes either

http://www.ukplumbersforums.co.uk/g...m-public-forum/18940-advice-gas-pipe-run.html

Touch too technical on pipe sizing

 

[Dannypipe]

It's before the days of censorship. Should be in the GS section.
