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.

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).
