What is wrong with my ravenheat white star combination boiler,?

Try removing the programmer or disconnecting the input to the boiler

Oned would have thought the engineers would have tried to narrow doen where the fault is but, just on case, suggest this:

Disconnect the room thermostat at the boiler to eliminate that and its wiring. If the boiler goes off, there is a fault in the termostat and / or its wiring. If the boiler doesn't go off, there is a fault in the boiler.

Reading this thread suggets it may be worth thinking about a new boiler (And not a Ravenheat one):
