Reset Code for Whirlpool Dishwasher

My Whirlpool Quiet Partner III dishwasher will not start. There was a power failure. Since then the LED above the "Glass Xpress" button flashes continually and the "Time Remaining" indicator shows "- -". I have tried several pushbutton sequences that are reset codes according to info I found on the internet but nothing works. Can you give me the correct code for this model number and any other troubleshooting recommendations? Thanks.
