Maintenance has been ignoring me , is there anything I can do to fix this? When they were here last fixing my sink he mentioned that this tube is dirty and needs to be cleaned… my dishwasher works fine but it isn’t cleaning well. I’ve cleaned the filter and ran a white vinegar load through it. But there’s this one weird dirty film on the walls of it and my dishes come out smelling not so clean. It was just replaced in March when I had my
Unit renovated. Any advice is appreciated
