Having googled through the archives I understand this is a common problem, but it seems my Potterton Suprima boiler requires a new circuit board.
I've been in contact with cetltd.com, as I saw someone in the group recommend them. However I'm a little confused over one issue, as the front panel of my boiler lists the GC code for my PCB as 41.607.75, whereas the PCB they stock, which they say is the same one, is listed as GC 114954.
According to them there are only 2 differant PCB's, which are easily identifyable by the type of reset switch they have. If this is the case then this is indeed the one, however could someone confirm this or explain why the GC codes are differant?
