i have a worcester 24 cdi combi boiler, the red light keeps flashing on the radiator dial, no hot water and the damned thing just keeps clicking and will not fire up ? i have pressed the reset button in the past which has worked, but not anymore ! the engineer has changed the condenser twice, but same problem again.
