Questions and answers
I can’t get my green star I to stay operating it keeps turning off
The Worcester Greenstar i System boiler may keep turning off due to several possible reasons:
1. No Power – Check if the boiler has a permanent mains supply. Inspect Fuse F1 (2.5A) or Fuse F3 (0.5A) and the transformer. If faulty, replace the control board.
2. No Live Demand – Ensure there is a live demand at ST10-L from an external room thermostat or timer. Some older thermostats may not return proper voltage.
3. Diverter Valve Issue – If the boiler operates without a live demand signal, check that no permanent live feed is present at ST10-L from another source.
4. Incorrect Piping – Ensure the cold inlet and DHW outlet are correctly piped and not crossed.
5. Flow Turbine Issue – If the boiler is not operating during hot water demand, test the flow turbine.
Further troubleshooting may require checking the control board and other electrical components.
