Customer Questions and Answers for Dishwasher Drain Hose With Check Valve by Whirlpool

Hello Bill, The only drain hose on the unit is the one that goes from the pump housing to the sink drain. It does go up the side of the unit and back down. This loop is necessary for proper draining so if it has to be replaced, this loop has to be present in addition to the loop up to countertop level under the sink before connecting to the drain. There is a fill line that runs from the home plumbing to the water valve and then there is an inlet hose that goes from the water valve to the water inlet assembly on the right side of the unit. There are no other water hoses under the unit external to the pump assemblies.
