Time to replace pcb on boiler?

[Harry Bloomfield]

Maybe the real fault was one of those which was quickly fixed ( low cost repair ) and then the PCB changed ( high profit "repair" ).

There are a lot of "reconditioned" PCBs on sale, one has to wonder how much these reconditioning / repair these PCBs needed and where they came from.

I agree completely, it is a nice little earner. I have inspected a few supposedly repaired/refurbished PCB's, whilst I would expect some evidence of repair, I have never spotted any.

How about non speculation and actual facts, this is from Vaillant website (available publicly) https://vaillantgroup.intelliresponse.com/public/?requestType=NormalRequest&id=1990&source=5&question=Ecotec F61&interfaceID=2

Which lists a PCB failure at the very bottom of the list, which suggests it to be the least likely cause.

Almost any boiler fault can be due to the PCB's software misbehaving, when it reports a fault - when it could be the PCB itself at fault. They idea is to discount the cheaper issues first, rather than blame the most expensive item.

Does this all seem legit to you?

It does to me. Cost is fine and guy diagnosed it correctly. I don't know why some jump the conclusion, every time, that someone is at it.

If he had just serviced it, it makes me suspicious that he may have created the potential issue deliberately, during the service, in anticipation of a callback.

That would be some trick Harry...Servicing a boiler and " planting" a fault with a slow burn time of a week..on any component..let alone a pcb..

Lots of armchair experts on this thread. Ive never replaced anything but the pcb for a F61 fault on a vaillant. Considering Wolseley book price for an ecotec pcb is £230 then £250 fitted is very reasonable (Note: He probably didnt pay book price for the part)

Maybe the real fault

More likely Bernard you are talking rubbish.

This is more what we are concerned about, as it all seems very coincidental. In hindsight, we probably should have had a second opinion first, but we were just in a bit of a rush to get stuff sorted for moving...

The engineer was correct in his diagnosis, he cannot have created that fault to gain extra work, and id say he knows his onions if he pitched up with the correct part. Plus his charge was more than reasonable.

He probably moved the "fault after 1 week of my visit" dipswitch into the on position.
Then put it back to off on return visit.

very common fault and the wireless alarm has absolutely nothing to do with it, you have had the correct job done at a very reasonable price, by someone experienced in these boilers regardless of what the armchair experts on here are telling you

 

[bernardgreen]

egardless of what the armchair experts on here are telling you

So what happens to this suspect PCB if the gas technician takes it away..... In some industries a suspect PCB would be destroyed on site to prevent it accidently re-used.

Not quite reconnecting a plug fully would do it and generate a fault.

I imagine it got chucked in the bin or correctly recycled. Modern boiler PCBs are far too complicated for your average RGI to fix with a soldering iron.

Every F61 I've had has needed a new PCB. Seems like the engineer is suspected of being dodgy because he knew his stuff and quickly and efficiently fixed the boiler. No pleasing some people.

No it doesn’t, it’s the highest percentage of likelihood of the failure.

Also I’ve only ever had F61 as a pcb failure too
