Engine managment light on after washing.

As in title, washed car on weekend to get all the winter crud out under arches with a pressure washer (not engine bay) and the warning light came on when i restarted the car any ideas? it still runs OK. Will it need re-setting or will it self check and reset. Wont be doing this again, its an 07 vrs.
