The low pressure light is on (not flashing) everything is calling for heat pressure is just over 1bar. The last time we got someone out he seemed a decent bloke and told me it was the fan and could need replacing but would the low pressure light come on? is it a symptom of the low pressure? Also would it be considered dangerous to remove the cover where the fan is housed and to try turning it thus to kick start it up while everything is switched on?

If system pressure is above 1 bar then pressure is fine. If there is a low pressure light it's usually tripped by a low water pressure switch. Would probably guess the water pressure switch is blocked
