Ariston A27 MFFI combi boiler noise and malfunction

[paulmcahill]

Hi all, we have an Ariston A27 MFFI combi boiler which is bahaving strangely. When a hot tap is opened a strange noise builds to a crescendo and then tails off when you turn off the tap. Befiore this started happening I replaced the air pressure switch when the boiler started to fail in start up when timed heating events ocurred. If the boiler was given a clout on the side it would light immediately hence the lead up to changing the AP switch. Despite the new AP switch the boiler would revert to the same behavior occasionally!! Now when the Hot tap is opened we get the rising , fairly loud trumpeting noise which tails off when the tap is closed and then the boiler refuses to start and the fan doesn't run (which is a new thing). By trial and error, if the boier is left switched off at the fused spur, ie no power to boiler for 2 days the boiler will relight without a problem once power is restored!! Will be OK for a few days, sometimes more or less, the noisy hot water continues and then once more after drawing hot water the boiler will refuse to start. HELP it's driving me crazy!! What is more annoying is that when I bought the boiler I specifically ordered a male one!!!!!lol!! Gotta keep sane with a little light humour - no offence intended.

If you can help I would be extremely grateful, regards, Paul Cahill

Sounds like it is time to get a rgi in to service the boiler and check the whole thing over.

Thank you for your reply to my posting bengasman, this I would love to do, unfortunately the system is installed in our home in NW France and not one of the artisans in our area will touch it as the boiler is 'unknown to them' and they claim the boiler is not available in France. I bought the boiler etc here in the UK as I could not find a similar one in France which was fitted with a time clock, something French boilers seem not to need although they are now starting to creep in! Surely it cannot be so different from a plethora of other makes available in France?

So if anyone is willing to offer their services...................don't be shy!!

Regards, Paul Cahill

That was not a very clever move Paul.
It said clearly in the documentation that this boiler is for UK only. Continental models are different and you now have an illegal and dangerous situation, get rid of the boiler in a safe way asap, and I don't mean rip it off the wall yourself.
If anyone over there finds out you have an illegal model, illegally installed, you are in deep manure. It is only in England that a man's home is his castle, on the other side they have real laws to make sure houses are safe.
And forget about insurance ever paying out if you are unlucky enough to have a fire.
They just go: ah, mais oui, eez illegal, vuk ov, we no pay you, ha ha ha, and goodbye lifesavings.
And to be brutally honest, I think they are right. You put not only your own life at risk, but also that of your family and those who happen to be nearby for the sake of saving a few bob.
You know the boiler is dangerous, but you shrug it off and try to do a bit of experimenting.
