Few inches of water standing at bottom of dishwasher after cycle. I have removed all parts (from the lower rotor blade and below, which amounts to about 4 pieces, including the round screen) in an attempt to find food or anything else that might be causing blockage. I can hear motor during drain cycle so I don't think pump is issue. I can't find any breakdown diagrams for my model so I am not sure where to go next. I am a little limited in exploration as the previous home owner had bright idea of tiling floor after machine installed so I can't pull it out. Any assistance would be appreciated. :confused:
