The boiler just blew it's 3rd logic board (at £130 a pop)... first when
in warranty, the other 2 outside warranty. Some suppliers won't even
sell you the part unless Corgi regtd.

This time board has been changed, and a new wiring harness came with it,
so fair bit of rewiring of boiler.

I contacted Baxi ... asked if there are any know problems on Baxi
Barcelona ... response was no problems.

I then asked if 3 logic boards in 5 years is acceptable, and what is
their MTBF for these boards ... to be told that information is not
available.


Apart from board failures, everything else runs a treat it's very fast
to heat up, fairly quiet and compact.


Anybody else any issues with this model boiler. ?


A little goggling will show you how much I appreciate these boilers.
I think my quote was something like "they would win a competition for the
poorest boiler ever made in both the design and reliability categories".

Isn't it possible for a third party to engineer a replacement controller
using open source software development? - or is there a Gas law against
such an idea?

Often thought about it, but the (e.g. insurance) implications, if there
were a problem are significant. Where there's a processor involved, you
can have secondary functions which might not be obvious without having
access to the software You would also prolly have to put up with a court
case brought about by Baxi,

Many boilers are just kits, using generic parts. Vaillant, Glow Worm,
Broag, Raventheat, Heatline, BIASI, Baxi, etc, etc, use the Giannoni heat
exchanger. Many use Grundfos or Wilo pumps, Dung Gas valves, Honeywell
3-way valves, Honeywell hydro assembly, etc. Parts are interchangeable. Go
to HRPC and the makers state the Honeywell type and part No, so they just
take one off the shelf.

Anyone can make one of these kits up (Ravenheat started making kit boilers),
except in one crucial part, the pcb. Yet I see no reason why a generic pcb
can't be made, Maxie may put us right in knowing some differing makers
using the same pcbs.

I read years ago, when they were talking about the OpenTherm protocol and
what functionality it should contain, about a generic pcb, with the same
sockets and plugs on the pcbs and colour coded etc. It was just wishful
thinking at the time. I don't think anything came of it. It would have
meant the user could just slide in a new pcb if one burnt out - a true DIY
job. The pcb was to have diagnostics and would indicate when parts of it
were kaput and needed changing. Then third party companies could make them
and keep prices down.

Yup. My brother's one broke down at least twice a year - and he certainly
got his money's worth out of his gas board service contract. Final straw
was the heat exchanger started leaking - on a boiler only four years old
or so. Even although repairs were 'free' the system was down for several
days each time while they tried to repair it - waiting for parts etc - so
he finally replaced it.

Whoops... err... I did in Feb 2007 after the Potterton lockout problems
reported back then on BBC's Watchdog programme.

There are off the shelf controllers for more basic boilers and fires.
Pactrol is a typical 3rd party "sequencers" used by a number of smaller
manufactruers.

However building your own boiler is such a non-starter so I won't even
start on that.

My point is that generic parts makes matters cheaper and parts freely
available.

It works pretty well for PC's. They're modular, interchangeable, and
component prices are very good.

Last time I looked you had to buy the correct motherboard for the
processor. And there are how many different processors? Sure you can buy
different makes of PCI etc boards and power supplies may be
interchangeable to some extent. But then the same might apply to some
boiler parts like pumps etc.

But PCs are made by the million for world wide sales. Boilers not.

Gas valves contain that mixture too and they are generic. Maxie, there is
no reason why a generic pcb can't be made. OpenTherem control is pointing
that way. Changing a pcb could be no different to changing a light bulb.
