Hot water from the tap works with no problems but the radiator side does not come on at all. Things I've checked:
* Boiler is in DHW + CH mode
* Radiator temp control on the boiler panel set to max
* Room thermostat is calling for heat (set to 30c)
* Digital programmer is calling for heat (tried Timed, Advance, Boost and Constant)
* Pressure needle in in the green zone.
Boiler is an Alpha HE CB33. Can anyone suggest any ideas what could have gone wrong?
