What could be causing my dishwasher to display a "water Inlet" error?
Actually it turned out to be a stuck impeller issue. Saw this video on youtube which was very useful. I didnt even have to use a broken fork - just a wire hanger to jiggle the impeller and everything worked fine (till the impeller gets stuck again...:(
