Samsung Dishwasher Circulation Pump Motor Parts — Models & Compatibility

Your Samsung dishwasher isn't cleaning dishes properly, or it's making a grinding noise during the wash cycle — chances are, it's the circulation pump motor. The DD81-01640A is the OEM-grade replacement that powers water circulation through your dishwasher's spray arms. This hub covers compatibility for Samsung DW80F and DW80K series dishwashers, including popular models like the DW80F600UTB and DW80K5050US.

Is This the Right Part for Your Model?

Before ordering, you'll need to verify your exact model number. On Samsung dishwashers, the model tag is typically located on the inside edge of the door frame — open the door and look along the top or side edge. You'll see something like "DW80F600UTB/AA" or "DW80K5050US/AA." Cross-reference that full number (including the suffix after the slash) with the compatibility list below.

About This Replacement Part

The circulation pump motor is what moves water from the sump through the spray arms during wash and rinse cycles. When it fails, you'll notice weak spray pressure, dishes that don't come clean, or error codes related to water circulation. The DD81-01640A replaces part numbers AP5957982, PS10067144, and 3447464 — it's the exact motor Samsung uses in their F600, F800, and K5050 dishwasher lines. This isn't a universal aftermarket substitute; it's built to the same specifications as the original factory part.

The part number DD81-01640A covers both AA and AC suffix variants across these series. Samsung uses the same pump motor assembly whether you've got a basic F600 or the premium WaterWall F800 — the mounting points and electrical connections are identical.

What Causes Pump Motor Failure?

Circulation pump motors typically fail from bearing wear or electrical winding burnout. If you've been running the dishwasher with hard objects stuck in the pump housing — like broken glass, toothpicks, or small utensils — the motor works harder and wears out faster. Power surges can also fry the motor windings. Most Samsung circulation pumps last 7-10 years under normal use, but high-mineral water or frequent heavy-load cycles can shorten that lifespan.

Signs You Need This Replacement

Here's what pump motor failure looks like: dishes come out dirty even after a full cycle, you hear a humming or grinding noise during the wash phase, or the dishwasher displays error codes related to water circulation. Sometimes the motor will run but produce weak water pressure — you'll notice the spray arms barely spinning. If the motor's completely dead, the dishwasher might fill with water but never progress past the initial fill stage.

Installation Overview

Replacing the circulation pump motor requires removing the lower spray arm, the sump cover, and disconnecting the motor's wire harness. You'll need to tip the dishwasher back slightly to access the pump from underneath — have a helper handy, or use a padded surface to protect your floor. The motor bolts in place with three screws, and you'll need to carefully transfer the impeller housing from the old motor to the new one. Most DIYers can handle this repair in 45-60 minutes if they've got basic hand tools and some mechanical aptitude.

Order the Right Part

The DD81-01640A circulation pump motor is priced at $175.99 — that's the OEM-quality replacement without the dealership markup.
