Flashing lights??? HELP!!!?

The other day my Electrolux Dishlex DX302 decided not to drain completely, we did a "dry load" (no dishes in the dishwasher) and that seemed to fix that problem... we used it a couple more times, everything was fine, but now all I get when I turn it on is "- -" flashing along with ALL of the other lights at the same time and won't let me do anything... HELP!!! I need this thing - I'm fresh out of an operating room and can't stand long enough to do dishes :( can someone please tell me what the heck I can do to fix???
