hi - i have a riello G2S burner on my boiler.
i think it ran out of oil - it was very low & wouldn't start so assumed out of oil.
refilled & bled without pump running - the pump but still wouldn't fire.
heres whats happening:
1) motor runs for about 20sec then system locks out.
2) no fuel is getting to the nozzle or air damper valve.
3) with bleed valve open & pump running fuel output same as without pump running.
4) cleaned fuel line filter - found inlet into it from tank was clogged.
5) removed pump - cleaned screen filter - no significant debris & pump rotates freely.
6) removed pump solenoid valve & found ok - can anyone explain its function?
any help greatly appreciated.
