They claim there is "no issue with the pcb" , despite the fact that
half the pcbs I repair are Suprimas


I was in my local Plumb Center 2 or 3 months ago and raised the subject
of my Suprima 80 constantly tripping out (this was before I re-made
every solder joint on the PCB thus fixing the fault). The bod behind
the counter told me that last year Potterton changed PCB supplier and,
wait for it, replaced all PCBs in Suprima boilers that were in store,.
i.e. pre-delivery. Does that sound likely?
