Maytag dishwasher not complete draining

I rarely use the dishwasher, but i do on occasion just so to keep it active. Never had put dirty dish's in it for fear of clogging, so when i do use it I set for Pots and Pans, and Normal wash.In such cases, after the washer shuts off, I notice some water near the drain that did not completely drained. The manual says to set it to Normal wash, wait 35 seconds than it should drain. First I find that instruction to turn on Normal wash an oxmoron...by setting it there, you can hear the water running again..so your adding more 'fuel' to the 'fire'. I know for a fact that it is not clogged by food, cause that is the one thing i made sure of not to add uneaten food scraps to it. Open to Any suggestions, please.
