FWIW
If you google Suprima PCB a number of people have said that re-soldering
all
the suspect dry joints cured the problem.



Poor soldering's a major problem, however, doing it properly is
delicate and quite a lot of people make a mess of it.


Yes quite possibly,
but not an unsurprising statement from someone who makes 50% of their net
income from Suprima repairs.




You should also be aware that there have been two revisions to the pcb in
an
attempt to fix this problem
The latest board (mid 2006) is very different to the original and come
with
a completely new wiring harness,
*IF* you can get potterton to replace your pcb with the latest one at
a
reasonable price this may be better then getting the old original
repaired/exchanged.


On what do you base this ?

The "IF" doesn't exist - they have a fixed price £185 + VAT (I think,
I'm not sure)


your quote
"It could be that Potterton will now be backed into a corner where they
will have to retrofit boilers after the watchdog progs ..."

Also this really boils down to whether the original lockout fault is down
to crap manufacturing or design
I cant (but you may) see much point in continually repairing a crap
design.
