Samsung Dishwasher Middle Spray Arm Assembly Parts — Models & Compatibility

Your Samsung dishwasher's middle spray arm is the workhorse that ensures your upper rack dishes get properly cleaned. When plates come out with food residue or you notice weak water flow from the center of the machine, it's usually this assembly that's failed. This hub covers the DD82-01064A middle spray arm assembly that fits dozens of Samsung dishwasher models from the DW80F, DW80J, DW80K, DW80M, and DW80R series.

Is This the Right Part for Your Model?

Your dishwasher's model number is typically located along the top edge of the door opening or on the left side panel. You'll see something like "DW80F600UTB" or "DW80K5050US" — match this against the compatibility list below. Samsung used this same spray arm design across multiple series from roughly 2014 through 2020, which means one part fits a wide range of models.

About This Replacement Part

The DD82-01064A is the complete middle spray arm assembly that mounts to the center of your dishwasher's tub. This isn't just the spinning arm — it includes the mounting bracket and water distribution system that feeds the upper rack. Over time, hard water deposits can clog the spray holes, or the bearings that allow rotation can wear out. You'll notice dishes on the upper rack staying dirty while the lower rack comes clean, or you might hear a grinding noise during the wash cycle. This assembly replaces part numbers AP5800424 and PS8764562, so if you're finding those numbers in your research, you're looking at the same part. At $111.99, it's significantly cheaper than a service call, and the swap takes about 15 minutes once you pull out the lower rack.

Compatible Samsung Dishwasher Models

This middle spray arm assembly fits the following Samsung dishwasher models. If your model number isn't listed but starts with DW80F, DW80J, DW80K, DW80M, or DW80R, there's a good chance it's compatible — just verify the model number format matches.

What Causes Middle Spray Arm Failure?

Hard water is the biggest culprit. Mineral deposits gradually clog the spray holes until water pressure drops to nothing. The bearing that allows the arm to spin freely also wears down over years of use, especially if you're running the dishwasher daily. Sometimes a piece of silverware or a broken dish fragment will jam the assembly, cracking the plastic housing. If you've been using low-quality detergent or skipping rinse aid, you're accelerating the buildup. Once the arm stops spinning properly, the upper rack becomes essentially useless — water just dribbles out instead of spraying forcefully across your dishes.

Series Coverage

This part works across Samsung's main dishwasher lineup from the mid-2010s through recent models. The DW80F series was Samsung's entry into quieter operation, the DW80J series added improved filtration, and the DW80K through DW80R models refined the design without changing the core spray arm engineering. That's why one assembly covers so many years — Samsung got the design right and stuck with it.
