I have a Whirlpool Gold Quiet Partner dishwasher model#GU980SCGS3. The dishwasher is leaking profusely on the left hand side of the floor during rinsing and filling. I took the door panel off and pulled the dishwasher out. I unclamped the drain hose and checked for clogs--no clogs. It "appears" the leak is coming from the other end of the the drain hose (where the rubber meets the check valve). Can this part be removed and examined, or replaced? Could the leak be coming from further up the rubber and dripping down. Please help! Thanks.
