Hi all,
Thanks to ollski and Paul yesterday.
I still have the same fault with the ignition of my Suprima 60 can anyone suggest another angle of attack.
Fault:
With mains power on Red LED flashes, press reset green LED on, fan runs green LED flashes, then flashes faster as ignition cycle takes place no spark from electrode. This cycles twice more then fan cuts out and red LED flashes. Once the boiler is back to a red flashing LED gas can be smelt from around the electrode area.
Continuity of all major components outside the PCB checks out, continuity of tracks and components on PCB and re-soldering as far as possible check out.
Electrode, electrode lead, thermister, and overheat stat have been changed.
PCB is a re-con, worked ok for a few weeks then system started to degrade, not comming on with timer in the morning, locking out during the day but would work after re-set, then eventualy lost spark even if re-set was pushed.
Using an independant ignition spark the burner lights and runs normal, C/H flow is achieved as normal until heat exchanger reaches its stat cut off. when heat exchanger cools below the stat the boiler cycles to run again. without using independant ignition spark, no spark at the electrode.
Surely this points to the spark generator, (a new PCB I fear)
Im stummped, any takers please.
