What causes the Worcester Bosch 2969 fault?
This fault occurs when the boiler's Intelligent Filling System detects that it is adding water too frequently to maintain pressure. It suggests that water is escaping from your central heating system, usually through a pipe leak or a faulty component like the expansion vessel. To prevent potential flooding or damage, the boiler stops refilling automatically and shuts down.
This fault often appears in autumn when the heating is first turned on after summer, as the change in temperature and pressure can expose small leaks or weakened seals.
