Whirlpool wont drain

dishwasher wont drain on its own..checked for clogs but found out if you just let it run it skips the drain cylce..if you turn the knob manually with your hand through all the cycles it will drain when it hits that cycle. is the timer out?

Sounds like the timer is the culprit.
