£700 for repairs to Ariston mincrogenus boiler and still not fixed...

[treefan]

Hi
Im going crazy over my Ariston Mircogenus 24 boiler (6 years old).

Its not heating water properly and you only get some hot water to the nearest bathroom as the water pressure has to be lowered. The ensuite gets no hot water at all!

So far I (well, my plumber) has

1. Replaced PCB board (£250).
2. Replaced secondary water exchanger (£190)
3. Replaces hot water sensor (ditto)
4. Desludged system (£250)

Water is still not heating properly!
Im tearing my hair out....what else can I don to get this boiler working????

find a cheaper gas engineer unless your in london those prices are absurd

Get a new engineer who knows what they are doing.
Where do you live?

Option 2 is to get a new boiler fitted.

Not everyone has the money to replace their boiler every 6 years.

What so throw away £700 plus I would hazard a guess a few days off work, seen it all before, crap boiler would have advised to replace with anything with a 5 or 7 year warranty or left with custard to get another engineer who "thinks" he can do a cheap repair........ hindsight is a wonderful thing, but a good substitute is real world experience

 

[Dannypipe]

Its had £700 thrown at it, and it's still not right. So they probably havent assessed the problem properly. £250 to desludge the system, isn't money spent on the appliance.

I repaired a boiler last week. £700 repair! I advised a change might be order of the day, but they didn't have a couple of grand to replace it. Like I said, not everyone does.

I agree with what you're saying in priciple, but like I say, not everyone can afford to heed your advise.

700 quid??? Was it this man.....

 

[treefan]

yep I feel like this...

and yes, a new boiler would have been the answer but I dont have the cash for this

post your location up in the need a plumber/gas engineer section there are loads of knowledgeable folk on here who can fix this for you

 

[buckley plumb]

sorry but would not have spent that much on a boiler that cost less than that new

As above get a better engineer to check, divertor valve is not passing or faulty dhw flow switch can't be much else?

 

[John_]

Just a thought could it possible be that the diverter valve is letting by? Thoughts anyone?

i bet if the plate heats been replaced and a powerflush done some rubbish has gone in the dv bottom safety spring and is holding it open

 

[mountainman]

I suppose the obvious question is with the CH off, does the heating circuit get hot on hot water only demand?

Yep a good chance, I could, as we all could.....say how to test for this, but I think it's best the OP gets a recommended RGI in!

Hi
Ariston Mircogenus 24 boiler

you only get some hot water to the nearest bathroom

Regardless of what may or may not be wrong with the boiler, you can't make a silk purse from a sows ear!

 

[buckley plumb]

have you got a mixer shower or tap turn off cold to boiler and open a hot tap there should be no flow if you have flow then a mixer is passing worth a check

That's awesome advice, once had this on my sisters WB, they had unknown to me hot and cold outside taps both joined by a y piece to wash the dog, trigger off on hose, both taps left open you can guess the rest, cold diluting the hot! Nrv's now fitted
