Hope someone can shed some light on this problem!..the boiler in either dhw or heating mode successfully ignites for between 10 and 15 seconds typically, then the gas valve shuts off appearing to be switched off by the pcb(measured on voltmeter). Then it will reignite and this cycling goes on indefinitely.Occasionally in dhw mode i can get ten minutes of hot water before it goes into its cycling antics...checked the spark/sense electrode and it seems fine as do the various ntc's.....it's so annoying as it's just out of warranty and i bought this boiler to replace a previous temperamental vokera..btw no fault codes ever appear either...
Anyone have any inspiration??
