samsung refrigerator

I am looking for a part that is not shown on any of the diagrams. the part attaches to the under side of a water valve, part #ap4165558 and above water nut part #ap4140125.

I know the part you’re describing and have not been able to identify it or find it anywhere either. It apprears to be an impeller of some sort to push water up the back of the refridgerator to refill the ice maker. The service/parts manual for the RS2544SL doesn’t show the item in the drawings. I’m considering buying the specific manual for the S2544SL/XAA (for another $25) but I don’t want to waste the money if the diagrams are going to be the same as the other service manual for the RS2544** model. I’ll keep searching and post if I find it. Let me know if you have any luck. Thanks-
