So I return..... the boiler has worked fine snce last episode in June //www.diynot.com/forums/plumbing/worcester-danesmore-rs-20-25-lock-out.405591/
Now after replacing Satronic control unit, ignition pack, pump and motor(yes I know cheaper to replace burner etc etc...). The boiler is quieter and fires most times. However sometimes it locks out, on reset the fan starts, ignition sparks then a comparatively long wait time before the oil solenoid clicks almost at end of timer cycle before lock out. On reset fires immediately. Is there a way of shortening the oil solenoid opening time ?
