Potterton - fan neon flashing, water only gets luke warm.

[deedgess]

Have noticed that one fin of the fan is 'AWOL' (broken). which might suggest the physical defect is registerring somehow? Other than that, the potterton fault finder suggests the fault could be with the pressure switch and googling the problem suggests the PCB is going west. Don't mind replacing whichever is duff - but a little loathe to replace all 3 parts!!! - any suggestions? otherwise, guess i'll start with the cheapest and work my way up....

My advice is to get someone who is competent and GSR to work on your boiler, before you kill yourself and your family!!!

 

[stratobuddy]

Where do the GSR regs start?

Changing a fuse in the boiler plug-top?

Changing a fan in a non-room-sealed boiler if you are a qualified electrician?

Replacing a PCB which is totally outside the "gassy area of the boiler" if you are a qualified electronics engineer?

Cleaning the outer casing even if you are none of the above (after all, that is "working on the boiler")?

Is this the same boiler that you have already changed the heat exchanger and PDV on? It would've worked out so much cheaper not to mention safer, if you'd got a qualified GSR in in the first place.

No, but looking at the fan and pressure switch which are to do with as you say "the gassy area of the boiler"

Depending on the boiler you do have to be gsr go all aspects because as soon as you remove the cover you compromise the seal. Best, really, to take a wide and sweeping judgement that all elements of a boiler must only be repaired or replaced by a gsr engineer. I have always believed manufacturers and suppliers should check for gsr before handing over spares of any sort.

I would rather shell out for a qualified mechanic to fix my car than entrust it to someone who changed a tire on a bike once.

Changing a fuse in the boiler plug-top? Do you know the correct rating of fuse for each boiler?

Changing a fan in a non-room-sealed boiler if you are a qualified electrician? You would be interfering with the combustion process and have not got the skillset/tools to check.

Replacing a PCB which is totally outside the "gassy area of the boiler" if you are a qualified electronics engineer?
Some of the PCB's have pots which need to be set up when changing over a pcb, (soft start for instance) again, you could be changing the combustion process with no means of checking if it is correct.

Cleaning the outer casing even if you are none of the above (after all, that is "working on the boiler")?
If that is your mind set then yes, if you consider this working on the boiler I presume you will apply the same rules to cleaning a gas hob or gas oven?.

The rules are in place to try and stop people who don't know what they are doing endangering themselves and others. I've no doubt some people are intelligent enough to know not to DIY but some people believe that because they have the necessary skills in one subject, this will enable them to transfer their knowledge when it comes to gas. Some people do it to save money, others because they don't like being told they're not supposed to do it.
This internet is a good tool but it is also the bug bear of every decent qualified tradesmen when their skills and knowledge is undermined by someone with google and a few hours to spare. Not only can it put people out of work but it can also put people out of life, think the next time you fancy having a go, if something happens "how will I explain to the court?, the wife?, the neighbours?".
Just sayin'...
