GlowWorm 30CXi completely dead

Dont mean to be ignorant but what did you mean about the forum rules?

Know its frustrating but forum rules dont allow us to give advice opening boilers to somone who is not gas safe, but am familiar with this paticular boiler and I am quite confident that your PCB is fine and its a quick fix,
Have done quite a few breakdowns with this model and its never been the PCB with the info you have give.

I would disconnect the pressure sensor and see what happens then, if the pressure sensor goes it looks like a board fault when it isn't. The pressure sensor is easy to spot, pink salmon colour. it is one of the first things I test when I go to a glow worm with what looks like a faulty pcb, obviously sometimes it is the pcb but it is so easy to check, just unplug the sensor and see what happens

Never come across the pressure sensor fault, used to go to 30ci for breakdowns reg on contract firm I worked for but that was mainly due to them not being flushed before installed!!!! Have changed half dozen boards on the ci and cxi and they've all had the fan pulsating and screen flashing.

True what they say...you learn something new everyday. Cheers fazed.

its not a common fault, just one I have come across in the past, when I looked closely at the pressure sensor it had sprung a tiny leak and shorted out across the wiring, not say it is that but it's too simple not to try it

Having said that I would get your man to ring GW tech if in any doubt beforehand and they will run through an additional test you can do to confirm

good luck with that one, just make sure you have a cup of coffee & 20 fags to hand before you phone them, worse customer service i have ever come across, helpful when you get through it's the 40 mins on hold that pisses me off

 

[suavegit]

With you on that one. Make sure you got plenty of tea on the go. Although you might be lucky and get through straight away, has happened once or twice

Well, after the comments on here, I've cancelled the engineer coming back tomorrow with a new PCB. I now need to find another who can come out in a hurry and has GlowWorm knowledge.

To answer some other comments, the flow sensor was disconnected, as were all of the other low-voltage elements, one by one. Also, some internal reset stat something or other was checked too if that makes any sense.

And frustrating isn't the word - infuriating is closer to it. Just don't see the point in a forum where people can only answer with "I know what's wrong but can't tell you" - just needs a nah nah na nah nah and a sticky out tongue to go with it I understand the logic about gas safety, however I imagine the chancers are going to meddle regardless, whether you share info on here or not. I doubt you are protecting anybody and in reality just making it difficult for people like me, who could have shared the info with my engineer and had a fixed boiler and an engineer who has gained some more knowledge for the future - everyone benefits. Anyway, I sense I'm getting into an argument I won't win on here so will say no more.

Options for tomorrow are either contact GlowWorm themselves and look into the fixed price repair and service contract (is it any good?) or find a local GlowWorm specialist who can come out. Decision may come down to whoever can turn up first. And if I take another punt on another random engineer, who's to say they will know any more than the last?!

Gareth,

A good engineer with a multimeter does not necessarily need to know the Glow worms inside out although does help. There are so many different boilers around that you do have to ring technical lines sometimes to help diagnose faults I.e getting resistance values for components and such like.

I also would like to know what the simple fix is, wonder if he was on about the reset (high limit stat) but you didnt point to any of those symptoms. As in previous post your man could have rung GW tech while in front of the boiler and done the dc voltage check to prove pcb fluffed.

Personally think you would have been ok with pcb change but thats only my opinion.

Cant help with Glow worm questions.

Hear you on the sharing front especially as misses pregnant. Can be a cynical bunch sometimes. No offence intended

Had a similar problem on one once and the culprit was the main on/off switch the one on the boiler worked by the rotary control knob.

 

[wizbongre]

Second engineer came out yesterday and also diagnosed PCB as the cause. He checked and there was no DC current coming out of it.

He's coming back today to replace it, as well as the dripping filling loop check valve that started all this by leaking.

Fingers crossed...

 

[ollski]

Doing one right now, done one yesterday. There must have been a powercut in this area in the last few days because they knock the SYMS out regularly.

Why do you think that your engineer is a nupty who needs your help to fix your boiler?

As thats his job dont you expect him to know more then you do?

If he needed help then he would ask in the closed part of this forum for RGIs.

Erm, no-one said anything about him being a numpty, or him needing my help. I said I could have shared information with him to help fix the boiler. Where's the harm in that, or is it only a valid fix if the engineer comes up with the diagnosis and fix on their own?

Yes I do, however as pointed out I doubt any engineer knows everything about every heating system.

That assumes he is active on these forums - am sure not all RGI's are.

As a non RGI customer, I am over a barrel hoping that the engineer I call out has the knowledge and experience to fix my problem - if he has the knowledge but not the experience, where's the harm in me sharing some info from on here with him?

Anyway, the PCB has been replaced and the boiler is now back up and running again. Subsequently, the leaking filling loop has been replaced too so hopefully no more slow leak from the system.

So, did you pay the first engineer who correctly diagnosed the pcb for his trouble, when you cancelled his second visit?

 

[Agile]

If you pay an engineer to fix your boiler then you expect that he will be competent to diagnose the fault without needing your help.

If he is a nupty and gets it wrong then you certainly dont need to pay for parts which dont fix the problem.

If he is in any doubt about his ability then he should not take on the job.

Most boiler parts are not returnable so its a big risk for him if he does not get it right first time.
