There is a high looped hose on the side of my Bosch integra 800 barely used craigslist dishwasher (take out after 6 months in a new kitchen of a manor home to convert the kitchen to a commercial kitchen for a bed and breakfast). In this case, is the under sink high loop not needed before it enters the side of the garbage disposal? The hose runs down from the high loop under the cabinets (removable toekick, accessible for inspection) and then up through the cabinet floor to the gd. The top of the high looped hose on the side of the dishwasher is a good 12 inches higher than where it enters the gd.
