Customer Questions and Answers for Dishwasher Spray Arm Radial Ring Bearing by Whirlpool

Tom, No, the spray arm components would not normally cause a drain issue in a dishwasher, you will want to replace them in order to maintain proper washabilty. You may want to start by disconnecting the drain hose from the plumbing under the sink and drain the dishwasher, this will usually clear any minor clogs in the pump and drain hose. You may need to disconnect the drain hose from the pump assembly and check the "Drain Check Valve" 675238 for clogs or debris. Good Luck and Thanks
