A friend of mine installed the exact same Kitchen Aid dishwasher that I have when she had her house built 2 years ago so it would be a 2007-08 model. Living alone, the only time the dishwasher is used is for family gatherings. The first time she used the dishwasher it would not drain because we found out the plumber had neglected to remove the plug from the plumbing drain connector. Ever since however, she has problems with the dishwasher draining - sometimes it will and most of the time it won't. Last night it wouldn't. The cycle was finished and the bottom of the tub was full of dirty water. I turned on the Rinse/hold cycle and then cancel but the water did not drain although I can hear the pump running and the drain hose is hot so the dishwasher is pumping the water. When it has happened before I did the same thing and the water did drain. The kitchen plumbing does not have an air gap but the drain hose is looped from the bottom of the cupboard to the top, exactly as it is installed in my house and I have no problems what so ever. Any ideas as to why it sometimes will not drain? I'm thinking there is some kind of problems with the plumbing? Thanks.
