I have a Side by side AEG fridge freezer RS 643 Vertuoso - everything works fine EXCEPT that the display icon which indicates water/ice cubes/crushed ice does not illuminate nor does it make ice cubes nor dispenses them. Water is on, freezer works fine, light inside works fine...BUT the ice dispenser appears not to be working. Any ideas? I've checked the connectors inside - they are fine. Is there an overload switch, maybe ? or some kind of cut out ?
