The boiler works fine for domestic hot water and the pressure remains at a constant 2 bar.
When the Central heating is turned on, the boiled fires up ok briefly but then shuts down.
It then goes through a restart sequence 5 times before locking out with the blue light off then flashing briefly on. The Lockout Reset button flashes too.
Any ideas?
