Thanks. Thats what I initially thought but I have bled the heat exchanger, the pump, the magnaclean and the rads and its all good.

Sounds very much like the OP is the installer.

If you can't follow installation instructions (as a DIYer or an installer) maybe you should find someone who can.

I'm sure Biasi would be thrilled to know how you are treating their product.

Why are you attempting to give advice on safety critical matters?

OP is your 'plumber' a registered gas fitter?

Sorry OP, the know-it-alls seem to have arrived so I'll leave it them to advise you to get some professional help. Good luck.

Yes, that's right the know-it-alls, otherwise known as the registered, qualified, insured and competent, have arrived.

I very much doubt if they will wildly speculate on diagnosing boiler faults on likely illegal installations, however desperate they are to prove how clever they are.

Did you change an old gravity/pumped boiler for this by any chance?

Hi.
Ive just had a new condensing boiler installed but the plumber cant get it working.

If it is the same plumber, sounds like he really knows his stuff about central heating installation.:eek:

Because it's a three year old Biasi?

Have I missed something about how old it is?

I tend to have the same thoughts as canucklehead.

Its a Biasi that has stood in the box for a good three years.

To answer the questions: I purchased the boiler three to four years ago for a kitchen refit that didnt happen. Since then its been sat, all boxed up, in the loft. The plumber is a retired corgi plumber (who can highly recommended) who now gets a mate, who is gas safe resistered, to check and commission the work. Nothing wrong with that is there? He did suggest that after that period some components may have seized. It was installed whilst I was on holiday and I have a phone message suggesting the pumb doesnt work correctly due to the 'no flow' error the boiler diagnoses. He has contacted Biasi but when told it had been sat for three years they didnt want to help! Since the plumber cant get back to me for a few more days I came on here to get as clued up as possible for his return. As the gas is connected there is no harm in me using the manual to see what I can find along with the help of this forum.
As it happens, I think I have located the problem. It seems that the pin on the diverter is not activating the primary circuit flow switch. When switched manually all seems to work ok. I have repeatedly depressed the pin to hopefully loosen it, and it does work...ish. The boiler now operates correctly but is hesitant at times. I assume there is some sort of diaphram inside the unit to operate the pin. Is this likely to have perished or do you think it will free up? The plumber did mention he had checked a diaphram and it was ok but at the time I didnt know what he was refering to. I would guess it is the same one? Prehaps he just hadnt worked the pin enough?
Many thanks.

Yes it is the same. Having now had a good look around, there is loads of blue/green stuff that has 'grown' around a lot of the joints. This cant be good, right?
For someone that was reliably recommended to me, Im not impressed!
