Yet another Potterton Suprima question!

[Agile]

In 2006 it should have been a condensing boiler installed.

In 2006 the boiler must have been old stock as they stopped making them several years before that.

I would only buy a gas valve from Parts Centre in a dire emergency.

Last one I bought significantly cheaper in the local area.

The final year of manufacture was 2006.

 

[DP]

So safe to say could easily have been fitted in 2007 I presume.?

 

[Agile]

Well that is surprising if they made them until 2006.

But even so the new PCB was not made until rather later.

The Siemens one was introduced in 2006.

Right then, can we agree that my boiler was installed in 2006 ( it was around the birth of my second daughter, it was done in a hurry because of this and was a direct replacement for the one that was in before, no doubt to keep installation to a minimum). As far as I know it has not had its PCB replaced before I did it a couple of weeks ago, but it is possible it was done as part of an issue when the gas valve was replaced.
All these things are moot though. I only want to know what is wrong with the boiler/system now, and how to progress. If you would like me to test some stuff I can do so, I may even have a contact thermometer lying around in the garage to check pipe temps if required. I have no problems checking out electrical systems etc, what I don't know is what to look for.
Any help in this matter is heat appreciated.

That is a distinct possibility as on that model it was sometimes found that a faulty gas valve would damage the original style of PCB.

Can you post a picture of the control panel of the boiler?

Again, you must be dreaming Sir. Explain how a gas valve switched by a relay will kill the board?
Precision and careful checking seems to be out of the window.

AND, I have the original board

Tony, like you say to other posters, care to reply to what I asked?

Thank you moderator, I was beginning to give up on this thread. Anyway please find attached a photo of my control panel, currently working for over 36 hrs but only lasted a couple before that. The HW is set on timer for twice a day, the CH is on all the time off a programmable thermostat.

Tony are you assuming faulty gas valve will kill the pcb or do you know that to be a fact.

Moderator. My response is relevant to what mr Agile posts. What he writes is based on assumption unless he can prove otherwise, what I posted is after Inexamined an old style pcb, so feel is relevant to the thread.

 

[Migs73]

Why does what PCB was in my boiler years ago matter. It is surely the PCB that is in it now that is relevant. I have posted a photo of the PCB I replaced, and a photo of the replacement, both if these are the newer style Siemens PCB. Both if these have shown the same 10 red flashes as a fault code, after my pump was replaced. It was a couple of weeks later that I first noticed the fault as it was tripping on lockout before that. The guy who installed the pump told us it would take a week or so for the system to "bed in" and it did. But after that the current fault manifested itself.

 

[Migs73]

And ?

I assume this is a request for more information. Please could you be more specific and tell me what information you would like me to tell you.

It is a distinct possibility that any defective item that uses a switched electrical supply can damage the switch that controls it. The risk increases when the switch has been selected without consideration that the controlled item may become defective and take far more current than the switch can handle.

The damage may not be immediately obvious. The switch still works but will degrade into total failure very quickly. Applies to relay contacts and semi-conductor devices.
