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

I cured a soldering fault on a Profile after some kind advice from
Geoff.

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.

The boiler was installed roughly 5 years ago so I guess they won't rush
an offer:-(

I'll have a look inside when the weather warms up a bit.


Curiously, we have two identical boilers installed at the same time in
the same block of flats. Clutching wooden desktop, only one has given
trouble!

missing "So far" in txt.

Yes. Perhaps Potterton suffer from *Friday* production issues.
