Worcester 350 boiler - low pressure light - gauge at right pressure?

Suggest you take out low pressure switch and either clean or replace it .as the water is not moving overnight it may be that dirt is lodging on the end of the sensor or water may be leaking into the sensor once you get it fired the heat and movement will masked the problem .You could link out the switch temporarily and see if the problem persist.dont think it will

I know the gauge is working ok, beacause when the system warms up, the pressure gauge shows a higher pressure.

are you sure the gauge is correct. it may be low on pressure and the gauge is stuck on 1.5 bar.
