The first knackered Potterton PCB of the season.

[Hugo Nebula]

My Potterton Suprima 30 was refusing to fire up for more than a few seconds yesterday, so I followed Potterton's Fault Finding flow chart. This got me as far as "are the two yellow wires to the thermister (sic) shorted?", which was a no. The next but one step was "are the two white wires to the temp control shorted?", which was a yes and therefore "replace Electronic Control", by which I assume they mean the PCB.

However, as part of checking, I inspected the wiring to the thermistor and carefully pulled it in and out. On reassembling everything, it now seems to be working as normal. Is it possible that it is the thermistor not conducting heat properly rather than the PCB?

Sorry - I can't help with your question but an an aside, how do I get hold of a Fault Finding flowchart for my boiler: a Potterton Netaheat 60e ? The only relevant document I can find is the User's Guide at

Unlikely I would have thought

Even if it doesn't have heat sink compound around it, being physically held in place, there's bound to be reasonable conduction to it from the immediate area.

What's the resistance at room temp and up at operating temperature ?

Flowchart?

You're joking

A) don't top post B) give us the symptoms

This disclaimer means that at least there are grounds to stop them

Unless anyone has a better disclaimer, I suggest anyone who takes offence to them stealing Uk-diy material, use what I have written above, i.e.

we can complain to their ISP, as this specifically states that they are not allowed to reproduce it

What you need is a disclaimer along the lines of "diyprojects promise to pay me £100 for each post reproduced. Reproduction of this post constitutes acceptance of these terms". Either that or start a thread with a title they wouldn't like and keep replying to it to put it at the top of their forum each time.

When my P S 80 adopteded the 'fire, fail to fault' mode of operating this time last year I remade all the solder joints on the PCB and it has worked fine ever since. Correction; it has worked as well as one can expect from that model ;-)

Err ... no

by copying posts which they are specifically told they may not, there is some come back with their ISP and thus they can be kicked

The Netaheat is not a complex boiler although it was ahead of the game 20 years ago.

What's the problem?

in a similar theme, who gave google to reproduce posts, and place contextual adverts? it would be interesting how much advertising money google get from people searching through this group...

prehaps google could provide some sort of community web space for hosting faq's or similar to compensate?
