Potterton Suprima boards are legendary for how cheap and nasty they are. It's a shame because otherwise it's a good boiler - very simple with cast iron heat exchanger and very compact (which will make it a pain to replace). It's also efficient for a non-condensing boiler.

Easy to avoid them now as the company doesn't exist any more - the brand name has been part of Baxi for some years.
