nylon radial bearing ring disentigrated/nut ok/lower split ring worn...would this be cause of dishwasher not draining completely ??
Answer 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
If I purchase the nut do I need a new Nylon Radial Bearing ring?
Answer Hello. If your nylon radial bearing ring is ok, then you can reuse it. If it is wore or broke, then replace it. Hope this helps.
