That's interesting....
I have a Suprima 50 and over the last 3 years since install, its had a new solenoid about a year ago and a new HT lead (3 weeks ago). Now its developed a problem where gas ignites and then after 3-4 seconds extinguishes. The three re-tries happen and then we enter lockout.
We thought we'd take the tried and trusted route of total power off to the boiler and leave for 5 minutes. 7 out of 10 times the fault goes away for a few hours but then returns. So... when time passes with no activity... it get better... is there a logical conclusion? Duff capacitor? Heat failure?
Either way Geoff, expect a call from me soon for a new PCB!
By the way, what's the difference between these parts on your website Geoff:
Potterton - Suprima - 407750 - 114954
Potterton - Suprima - 510216 - 114954
My user guide refers to 114954 PCB Issue 04..?
Cheers
