Hi,
I’ve searched previous threads with no luck and I’m having the following problem with a Worcester 28i Junior.
This problem started after the room controller was changed to have the heating on for a longer period whilst painting, but has continued now the controller has been back to the previous setting.
The system has the following symptoms:
Thanks in advance,

I’ve searched previous threads with no luck and I’m having the following problem with a Worcester 28i Junior.
This problem started after the room controller was changed to have the heating on for a longer period whilst painting, but has continued now the controller has been back to the previous setting.
The system has the following symptoms:
- If no CH demand, then the boiler will show a fault (1 second flashing)
- It will reset for a few seconds before the fault light begins flashing again
- Will only reset and run if a CH demand is imposed from the room controller
- If CH demand, then boiler will reset on pushing button and start as normal
- With boiler cold (e.g. in the morning), if CH demand then boiler will start as above once reset (as above).
- If DHW demand then the boiler will fault and shutdown.
- If boiler allowed to run for 2-3 minutes before opening hot tap
- Then the boiler will not fault, and produce CH and DHW as normal.
- With boiler cold (e.g. in the morning), if CH demand then boiler will start as above once reset (as above).
Thanks in advance,
Jamie
