Hi all
Sorry to repost but better info this time.
Above boiler initially seemed to be cycling ( 20 secs on/150 secs off) on CH quarter thermo setting.
Boiler would fire, temp lights go to 60 degrees, boiler stops, temp lights go back down to 40 degrees within seconds.
Bloke at Biasi suggested CH probe. Changed - but does the same.
Now noticed another symptom. After running CH on high therm setting (3 quarters to full), after running DHW for shower for 5/10 mins, CH appears to be reluctant to come back on.
Now starting to suspect Diverter/Diaphragm.
Help?
