Vaillant ecoplus

[quality]

Hi all
Been to one of these this evening customer says its clicking and no heating or hot water.

I took the front off and I was amazed !!!!!

The suction pipe / air inlet was melted all over the front of the main heat exchanger as was the wiring loom that feeds the air pressure switch and gas valve etc.

I cleared off all the melted plastic separated all the shorted out wires and gave it a try and it worked like a good en.

I did not take any readings or any thing I just turned it off and said I will come back tomorrow which I will but

Has anyone experienced this with a Vaillant eco as they all very similar

ps I do not know the history of the boiler as its the first time I have seen it

cheers

yes i have experienced it and gas safe have a tb on it get back there and make it safe the heat exchanger gasket has failed it may be a right off

No worries I capped it anyway as it was late an to be honest I could not be bothered as its been another long day.
Thanks for the TB bit

All the early Ecotec boilers had neoprene exchanger gaskets replaced with graphite ones under warranty. Boilers that had not been registered could not be traced so there will still be some out there with the old gaskets.

sounds like qualitys custard will need a new boiler

Think you can tell if its had a gasket change,as the replacement washers that came with the graphite gasket were lock in type rather than the flat type..I think thats correct ,i might be talking crap..

I will let you know the outcome tomorrow but gas man is on the money

should have a updated sticker fitted on the case but i think not in this case as the air intakes melted(it knda gives the game away)

To be honest I do not think it has been touched since it was installed

There was a certain ambiguity when I asked when was it last serviced

 

[Billy Bob Bob]

sell them a nice baxi duotec..............they dont have this fault,just for your info quality glowworms have the same fault,being part of valiant and sharing the same heat exchanger also the heat line vizo 24 + imported by yes you guessed it valiant

Yea your right again Gas man !! I am still having issues with a ideal isar he 30 did have a lot of graphite coming through on the inlet ,the boiler was noisy on low fire demands,and locked out ,checked all gaskets,seal on boiler then changed gas valve ,worked 4 couple of days but is playing up again going back to see it saturday,i think its pulling graphite through thge supply,can i get a filter fitted on inlet as i am concernd about fine particals affecting the new valve WHAT DO YOU THINK!!!

What year were ecotecs fitted with the new graphite seal?

 

[Billy Bob Bob]

not sure about a inlet filter some gas meters have them fitted, if you think its dragging debris through the gas line have a word with the supplier

[Kmort78]

Cheers Dan, Its ringing bells tbh, I serviced a gloworm system boiler last month and the service kit gasket set (2parts) was graphite.

Been back today as gas man said its gasket on burner, to cut a long story short I have a list of parts as long as my arm to make the repair good, which total to nearly £400 plus my bonus and a days pay £360.00.

I advice it would not be much more money for a new boiler.

We agreed on a price TO REPAIR IT

Some people are totally mad

 

[Billy Bob Bob]

how much is the new heat exchanger costing?

how much is the new heat exchanger costing?

123 + vat
I was quite surprised how cheap the heat exchanger flange and gasket kit was at just £60

When I spoke to vaillant to day they confirmed my suspisions that the boilker had never been registered as they had repaired 8000+ boiler free of charged due the the gasket faliure

 

[Billy Bob Bob]

less than i thought

Either way repair or new boiler I will get my money but I know which way I would have gone
