D/W no longer has enough water pressure to turn the arms (water sort of dribbles out of the bottom arm and nothing out of the upper arm). The motor continually runs until "cancel drain" is input. Not sure if this is a recirculating pump problem or a water valve issue or something entirely different. Have cleaned the filters/screens, impeller turns easily, water/drain hose are clear. Any suggestions on what I coulda/shoulda/woulda? I'm happy to either order parts to begin repair or embark on other steps to get clearer diagnosis... much obliged in advance for your consideration and assistance.
