No power to Caple DI414 Dishwasher?

Hi,

Have just moved into a house that has the above machine installed as a built in unit. However pushing the on button does absolutley nothing. I have checked the socket and fuse both of which are fine. The water supply would appear to be good as it is coming from the same pipe as the cold tap, which is functioning fine.

I'm out of ideas, having never owned a dishwasher before I'm wondering if I'm missing the blindingly obvious here?
