worcester 9.24 pcb urgently required

[mcav]

Hi Tony, and thanks for your reply.

Just to clarify, I pay around £200 per year to this company to keep my boiler running, not for them to pitch up and say they want to sell me a new one.

As mentioned, the boiler is running right now, with the only problem being that it is taking a little bit longer to ignite. I saw the igniter spark perfectly when the engineer moved the igniter contact a little closer to the metal pin of the igniter (he moved at away from the pin again) He then decided that the fault must be with the PCB which he says is incapable of sending a strong enough spark to the igniter. If that is the case, I would imagine that it would not spark at all. I also noticed that there seemed to be something built up on the contact for the spark which I think could affect its ability to conduct the spark.

So basically, the boiler is working for the time being. Can the PCB actually be at fault or is it possible that the igniter is problematic?


Any assistance is appreciated.

Unfortunately, your imagination is not up to the standard required!

The spark should be about 14,000 volts which will jump a gap of about 5-6 mm although the gap is usually set to about 4 mm!

Are you really unable to understand that its quite possible for a spark generator circuit may still be providing an output voltage but not at the full voltage?

Tony,

Is there any particular reason why you seem to reply as if you are trying to win some kind of argument?

As I stated, it was sparking continuously until the engineer separated the pin and contact. Now it sparks less frequently, which is reflected in the fact that it takes as bit longer to ignite the boiler. As I mentioned, the boiler is igniting.

If you are hell bent on just replying with rhetoric, please do not bother. It is assistance I am looking for, not pedantic commentary.

Thanks.


Simon.

I'm updating this post because I have a solution to my problem.

I was not convinced by the engineer's insistence that I needed the new PCB. I raised a complaint. Yesterday evening, an engineer confirmed that the PCB was absolutely fine and it was in fact the electrode that was damaged beyond repair (it actually fell apart in his hand when he removed it to look at it). To be clear, the first engineer had 'proved' that it was the PCB and 'proved' that the electrode was fine. The electrode and gas injector have been replaced (injector as a precaution). I'm posting this because while I am sure most engineers are not like this, if I had not question the initial verdict, I'd be shelling out for a new boiler right now, instead of soon.

I think that if you read back over what I was telling you then you will see that I was on the right track.

What do you expect the BG engineer to do when they get a commission of about £25 for booking a quote appointment with you?

Hardly likely to encourage him to fix your boiler.

I would always say go to a competent independent who specialises in repairing boilers rather than just installing them.

It's a whole £10, Tony!

A customer can't go to a "competent independent", they can only go to an "independent". There is only an educated guess, at best, as to whether or not an engineer is "competent" even if he/she does specialise in breakdowns. If only it was so simple!

Oh dear, I think I have just thrown away the PCB for my old 9.24 boiler.

I kept so much of it down in the cellar for spares to flog on the bay but never bothered. Tidied up a little while ago.

Good job it wasn't needed.
