Watched on-line video + consulted manual that came with dishwasher. actually, manual sufficed as it was an easy job (replacing the hose). [getting the dishwasher removed from under granite counter top proved a bit more challenging but manageable. Comments below pertain to entire job: read manual, unhook dishwasher plumbing, remove dishwasher from housing, remove hose/replace hose (trivial: 2 minutes), put it all back together. ]
