Samsung Dishwasher Circulation Pump Parts — Models & Compatibility

Your Samsung dishwasher suddenly stopped spraying water during the wash cycle, or you're hearing a grinding noise that wasn't there last week. Nine times out of ten, that's your circulation pump calling it quits. The DD82-01589A circulation pump assembly is Samsung's go-to replacement for their DW80 series dishwashers manufactured from roughly 2016 through 2024.

This pump does all the heavy lifting—it pulls water from the sump, pressurizes it, and forces it through the spray arms to actually clean your dishes. When it fails, you'll know immediately because dishes come out still dirty or the washer just sits there humming without doing anything useful.

Is This the Right Part for Your Model?

Look for your model number on the inside edge of the dishwasher door. It's usually on a white or silver sticker and starts with "DW" followed by numbers and letters. The DD82-01589A fits the entire DW80M, DW80N, DW80R, and DW80CG series, plus several others. If your model starts with DW80, there's a solid chance this is your pump.

Cross-reference your full model number against the compatibility list below. Samsung uses the same pump architecture across multiple series, so one assembly covers dozens of models. Don't mix this up with the drain pump—that's a different component entirely that only moves water out of the machine.

About This Replacement Pump Assembly

The DD82-01589A replaces OEM part numbers AP6807546, PS12709106, and 4958704. It's the complete assembly—motor, impeller housing, and mounting bracket all in one piece. You're not just getting the pump motor; you're getting the entire water circulation system that mounts to the bottom of the tub.

Samsung circulation pumps typically last 5-7 years before the motor bearings wear out or the impeller gets jammed by broken glass or food debris. When they go, you'll either hear loud grinding, complete silence where there should be water spray, or the dishwasher will error out mid-cycle with codes like LC, 4E, or 5E depending on the model.

This is a moderately difficult repair—you'll need to pull the lower rack, remove the spray arm, and access the sump area from inside the tub. Plan on about an hour if you're handy with tools. The pump connects via wire harness and three mounting screws, but you'll need to tip the dishwasher back to reach everything comfortably.

Compatible Samsung Dishwasher Models

This circulation pump assembly fits the following Samsung dishwasher models. We've listed the most common series below—if your specific model variant isn't shown but starts with the same base number, it'll likely work:

• DW80M2020US/AA — DW80M Series
• DW80M2020US/AC — DW80M Series
• DW80N3030UB/AA — DW80N Series
• DW80N3030US/AA — DW80N Series
• DW80N3030UW/AA — DW80N Series
• DW80R2031UB/AA — DW80R Series
• DW80R2031UG/AA — DW80R Series
• DW80R2031US/AA — DW80R Series
• DW80R2031US/AC — DW80R Series
• DW80R2031UW/AA — DW80R Series
• DW80CG4021SRAA — DW80CG Series
• DW80CG4021WQAA — DW80CG Series
• DW80CG4051SRAA — DW80CG Series

All models listed use the same pump mounting configuration and electrical connector. The DW80 platform has been Samsung's workhorse dishwasher line for nearly a decade, so parts interchangeability is excellent across the series.

What You Need to Know Before Ordering

At $279.99, this isn't a cheap part, but it's still way less than a new dishwasher. Make absolutely sure the circulation pump is your problem before ordering—if water isn't entering the machine at all, you've got a water inlet valve issue, not a pump issue. The pump only moves water that's already inside the tub.

Test by starting a cycle and listening. If you hear the inlet valve fill the tub with water but then nothing happens when the wash cycle should start, that's your circulation pump. If you don't hear water entering at all, look elsewhere first.
