Boiler fault ?

Thank you for your reply
I brought new PCB for £80 to day found that it did the trick
now notice that the green lead lights alternate across in pairs 30 40 – 50 60 – 70 80 when I use DHW any ideas what this means

70+80 means no flame has been detected.had this fault recently . was advised to change the ionisation electrode,£40. did not cure the fault.the cure was to change the printed circuit board £130+. bought a reconditioned unit for £50 from all-spares-direct1,part no 1308723.they gave very good service. check all connections,fuses etc first.
