Needed to determine if problem was with control panel (keypad) or circuit board. Cleaned corrosion off ribbon cable with Majic Eraser as per directions on internet (http://www.instructables.com/id/DIY-fix-your-Maytag-dishwasher-on-the-cheap/), and dishwasher lights worked better but dishwasher still wouldn't run. Then ran diagnostics per dishwasher “users manual/troubleshooting guide” that came with the dishwasher by pushing keypad buttons in 1-2-3-1-2-3-1-2-3 sequence. Instructions said to press any three keys in the sequence. Had to try several different sets of three keys for the 1-2-3-1-2-3-1-2-3 sequence, since I didn't know which key or keys were stuck. Flashing light then blinked diagnostic code as per “users manual/troubleshooting guide”. Diagnostics that came up were 2-1 (stuck key) and 10-1 (soap dispenser solenoid). Since key was stuck, ordered new control panel (keypad) rather than new circuit board. Installed new control panel and dishwasher is working just fine. I am not a repairman; anyone can do the fix by following the instructions.
