Advice please for non-igniting Worcester 24i

[ZuD]

Hello,

I'd really appreciate your advice on my Worcester 24i RSF.

We came back from holiday to a leaking aav. I've replaced that (and the pressure release valve that conked out mid process) but the boiler still won't ignite for hot water or central heating.

Although the circuit board didn't seem wet, there were water marks on the casing, so I left the board to dry out over four days, and have tried a hairdryer on it. Still no ignition.

The red light is on constant, I've changed the fuses, the relays look ok, the fan works, the pump sounds like it's working, and so I'm not entirely convinced it's the circuit board that's the problem.

The flow switch was replaced a couple of months ago so I doubt it's that.

Is it possible it's something else? Following the aav leak, there was sitting water on the metal under the combustion chamber. In your experience, do the connectors to the ignition corrode in these circumstances? They look a bit grubby but not too bad and seem well encased. Are they easy to replace? (I'm a DIY novice)

Should I admit defeat and try a new circuit board?

Thanks for your help!

As your not gas safe you need to get a gas safe engineer as you have already broke the law

no you should admit defeat and get a gas engineer in to fix your boiler

I got a pretty good idea what it is but am not prepared to tell you as mentioned already you have broken the law and i dont think anybody else should tell you either, we pay a lot to train and have all the correct equipment

Well said destroyer.If we answer these questions we might as well ebay our tools

OK, thanks everyone - got the message loud and clear! I have called an engineer. Still curious to know what the fault may be but appreciate why you don't want to tell me. Sorry to have misunderstood the purpose of this forum.

Sorry if any upset caused but gas is only allowed to be worked on by gas safe registed engineers

I think the lads have given you priceless information as ultimately tinkering on your own could cost you your life or that of your family.

if you was gas safe registered we would tell you, but unfortunately your not..and by already removing the PCB wow?..have you done the mandatory electrical checks? before??..if not then as stated have an engineer look at the issue he will resolve it..and make sure he is gas safe registered..not a cowboy!.. good luck.

Thanks, Hardy1. I'll ask the engineer to give it all a check-over. I've contacted a Corgi-registered person whose done a service on my boiler before so I know he's good.

SimonG, yes, true, I see that now. I only meant that the forum is probably more for professionals to exchange ideas, tips etc between each other and that it's less about giving people in my situation detailed advice (other than when it's appropriate to call in a professional).

If you'd asked about most other aspects of plumbing you'd have got a lot more info but gas is a different matter and not something that we encourage DIYers to tamper with.

Fair enough, I appreciate that.
