How can I fix control panel of Zanussi oven?

I stupidly knocked over some hot water which seems to have got into the control panel of my Zanussi oven.(Built-in ZBM878X) The time clock is repeatedly flashing and nothing else works. I suppose this means I will have to replace the control panel. Anyone have any ideas? We live in Greenwich should you happen to know a local specialist. Would be grateful for any replies.
