We are not getting hot water Whymight that be?

At the moment the boiler does not heat the water. The Green light is on.When the dial is on Radiator/Water the light remains on if we put it to Water only the light goes off.
It is a Potterton 24

Green light should be on 24/7 either water only or with heating. there may be electrical fault on switch contact where you select switch function
