Sometimes my Kenwood Prospero won't start. I'm pretty sure it's failing to release the safety catch when the top is put down. Sometimes a bit of jiggling will fix it. I know there are two other safety catches on the top to make sure that the blender or food processor are in right when in use. Is there a similar one for when the main top of the machine is down? Can anyone tell me where to find it - have opened up the top to look myself and can't see anything obvious...
