Val W Eden , UT June 17, 2019 Appliance: Samsung Dishwasher DMR57LFS/XAA-0000 Samsung Dishwasher Dmr57lfs/Xaa-0000 / : Impeller that pumps water to wash arms was broken at its' hub. How to replace Dishwasher Spray Arm Holder Nozzle. Dishwasher model DMR57LFS calls for a DD97-00136A impeller that is no longer available. I ordered impeller DD94-01003A which fits perfectly and dishwasher is working great. Not sure why this part is not shown as a suitable substitute. 2 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
