Questions & Answers

For Whirlpool Dishwasher Spray Arm Retainer Nut (Part Number: OEM18041517)

Cindy for Model Number kudi24se

I've got much the same question as Sarah S. did, plus a second one about draining (actually our original problem). The gasket below the arm retainer on my dishwasher is paper thin and flexible. The part you're recommending looks way too thick, and based on yet another person's comment about that nylon bearing, I believe it will prevent the arm from moving if installed. Suggestions re: gasket below the retainer nut? (I don't know whether it was previously fixed in place on the underside of the nut or below it because someone else took the dw apart. Next time we photo document as we go.) And our first problem was actually that the dw hadn't fully drained. Having taken apart the lower wash arm assembly and looked at food screens and drains, we ran it again, and there's still a little water in the bottom, but not much. Apparently, some water is necessary to keep pump seal moist? We didn't get deep enough in to look at the check valve, but if we have further drainage problems, that will be the next thing we examine. Thank you so much, Cindy

Cindy, The spray arm bearing will sit down inside the spray arm and will work for your unit. For the draining you will want to check the check ball to make sure that it is moving freely.

Sarah, The Radial bearing ring WP9742946 serves two purposes, it acts as a seal, to keep the water in the spray arm and produce a higher rate of force on the water to clean the dishes, and it acts as a "smooth" surface for the sprat arm to turn or rotate on. If it's distorted, it needs to be repalced as well. Thanks

Hello Annette. You will need to try to use needle nose pliers to hold the nut to unscrew it. You can also try cutting a slot in the top of the nut and using a flat blade screwdriver to unscrew it. Hope this helps.

Hello Annette. You will hold the spray arm and turn the nut with the wing on top to remove it. Hope this helps.
