I have a Potterton Suprima 80 with all the signs of the PCB lockout
problem.  Is replacement of the PCB a DIY job from the angles of 1) is
it possible without specialist tools and without specialist electronics
knowledge/skills 2) is a layman allowed to do it by law?

I'd appreciate any information you have.

Mike

Loads of people have tried this on here. I don't think it's supposed to be 
too challenging if you're slightly techie.

Isn't it about time these Suprima's were shipped with at least one spare 
PCB? Or to make life easier, maybe just perhaps modified?

If these Suprimas were a TV or something, you'd have grounds to sue the 
seller, even outside the warranty, on the basis that it wasn't fit for the 
job and should have lasted longer. I wonder if it's worth trying?

No, just be sensible and mark which lead came from where, most all are
on keyed plugs. If you've got a digital camera then take some close-ups
first in case you end up with an extra wire;!..

I'm sure if your getting one from the groups resident Suprima authority
then I'll expect it comes with instructions.

And AIUI if your doing it for yourself then you need to be "competent"
and thats really down to you, but your not touching the "gas/es" side of
it, so I wouldn't be that concerned.

The things a heap of cack and possibly the worst boiler ever made.

Any advance on that statement?......

Couldn't agree more - 5 year old Suprima 100: just replaced leaking heat 
exchanger and will, probably, be replacing the PCB when I get back from 
hols (leaving SWMBO to look after unheated house!!)

See my ealier thread.

It's no more difficult than replacing a circuit board in your PC. You only 
need a screwdriver to undo the holding screws.

As others have pointed out, just be sure to note which plug goes where and 
you'll be fine.

Not sure about the legality, but even the engineer who looked at mine 
admitted people can and do change these boards themselves (even though 
perhaps they're not supposed to).

Drop down the panel

undo the 4 screws holding the pcb in place

remove the connectors

Replacement is, as they say, the reverse of the above

Apart from the temp sensor connector and the OH stat connector, it's 
impossible to get it wrong, as all the connectors are of different 
length

apart from the HT lead, and earth connector, which are obvious

You would have to be bloody incompetent NOT to be able to replace a 
Suprima board.
