Was in my local plumbers merchants on Friday and the conversation
turned to the above boiler.

I observed how poor they are and that I had only stopped mine from
randomly locking out by removing the PCB and re-making all the soldered
connections. Whereupon, bloke behind counter commented that he had
replaced his Suprima after the heat exhanger had crumbled away and also
that Potterton had changed the PCBs in all unsold Suprima boilers last
year having changed the PCB manufacturers. Interesting, no?

Not before time - shame it's a good earner

Potterton assert that there is "no issue with the pcbs" ha ha
