Hi all, I've read the messages from 2006 and before regarding
potterton boilers. I have a Suprima 50L which is "locking
out" (showing as a red LED). The boiler tries to fire up, initiates,
lights, runs for about 15 seconds and then locks out again. Now the
reason for posting is that the engineers have been out twice and
replaced the circuit board within the boiler and the air pressure
switch. They run a quick test, i.e. turn it off and then turn it back
on again, and the boiler always fires up. The infuriating thing is
that as soon as they have gone, the boiler locks out again (after
about an hour). This has been ongoing for about 2 weeks now and is
costing a fortune in repairs.
I think that it is not the boiler itself, but the honeywell control
unit that runs the programme. Should I get this replaced as well?
