The red light is flashing (Fast Flash - 5 per secnd) on the hot water indicator for my Worcester 24cdi boiler?
Mabs asked:
The red light is flashing on the hot water indicator (D.H.W Demand Indicator) for my boiler which is a Worcester 24 cdi. The Hot water and the central heating are both not working. Any advice of what checks i could make before calling out for a plumber ?

According to this:—customer-care-guide.pdf
… it is:
“Air flow fault (RSF). Flue gas spillage”
I feel confident you should call a serviceman (engineer).
On edit:
Lots of potential causes: bad combustion fan; faulty pressure switch; bad spill switch; blocked/damaged flue; inadequate make-up air.
This isn’t a common error that will have a simple fix.

Did you get it fixed? I have exactly the same problem…
