WHAT CE1 TYPICALLY INDICATES
Indicates low system water pressure — the boiler has detected pressure below its safe minimum operating range and has stopped to protect itself.
WHAT TO DO
Check the pressure gauge on the front of the boiler; if it reads below roughly 1 bar, most Worcester Bosch boilers can be safely repressurised by the homeowner using the filling loop, following the instructions in the boiler's user manual. If pressure keeps dropping after topping up, that points to a leak or a faulty component elsewhere in the system, and This is not a DIY fix — it requires a Gas Safe registered engineer to diagnose and repair safely.
