Samsung Dishwasher Detergent & Rinse Aid Dispenser Parts — Models & Compatibility

Your Samsung dishwasher's detergent dispenser assembly controls the timing and release of both detergent and rinse aid during the wash cycle. When this component fails, you'll notice dishes coming out covered in undissolved detergent pods, streaky glassware, or the dispenser door not opening at all. This hub covers replacement dispenser assemblies compatible with Samsung DW80M, DW80N, and DW80R series dishwashers.

Is This the Right Part for Your Model?

Before ordering, you'll need your dishwasher's full model number. Open your dishwasher door and look along the top edge of the door frame or on the side edge — you'll see a label with the model number starting with "DW80" followed by additional characters. Cross-reference this with the compatible models list below. The DD81-02628A replaces older part numbers AP6807446, PS12593036, and DD81-02202A, so if you've found any of those numbers in your research, this is the updated replacement.

About This Replacement Part

The DD81-02628A is a complete dispenser assembly that includes both the detergent cup and rinse aid reservoir with the electronic actuator mechanism. Samsung designed this as a single-piece replacement rather than individual components because the dispenser door mechanism integrates directly with the control board's wash cycle programming. The assembly mounts to the inside of the dishwasher door and connects via a wiring harness to the main control. When the control board signals the appropriate time in the wash cycle, the actuator releases the spring-loaded door to drop detergent into the tub. The rinse aid portion works similarly but dispenses liquid gradually during the rinse cycles.

Common Signs You Need This Part

Dispenser failures typically show up as detergent pods or powder remaining in the closed cup after the cycle completes. You might also see the dispenser door physically stuck shut or, less commonly, stuck open from the start of the cycle. Rinse aid problems appear as spotty glasses and dishes that aren't drying properly. If you're adding rinse aid but the level indicator never goes down, the dispenser mechanism has likely cracked internally. Some failures happen suddenly after a power surge, while others develop gradually as the plastic actuator arm wears down from hundreds of open-close cycles.

Compatible Samsung Dishwasher Models

This dispenser assembly fits the following Samsung dishwasher models. All are front-control models from Samsung's mid-range and budget lines manufactured between 2017-2020:

• DW80M2020US/AA-00 — 24" Built-In
• DW80M2020US/AA — 24" Built-In
• DW80M2020US/AC — 24" Built-In
• DW80N3030UB/AA-00 — 24" Built-In Black
• DW80N3030US/AA-00 — 24" Built-In Stainless
• DW80N3030UW/AA-00 — 24" Built-In White
• DW80N3030US/AA — 24" Built-In Stainless
• DW80N3030UW/AA — 24" Built-In White
• DW80R2031US/AA-00 — 24" Built-In
• DW80R2031US/AA — 24" Built-In
• DW80R2031US/AC — 24" Built-In
• DW80R2031US/AC-00 — 24" Built-In

Note the suffix codes after the model number (like "/AA" or "/AC") — these indicate production revisions but use the same dispenser assembly. If your model number starts with DW80M, DW80N, or DW80R and isn't listed here, check the full compatibility list on the product page or contact support with your complete model number.

What's Included

The DD81-02628A comes as a complete assembly ready to install. You get the main dispenser housing with both detergent and rinse aid compartments, the electronic actuator already attached, the wiring harness connector, and the mounting clips. You don't need to transfer any parts from your old dispenser — this is a direct swap. The rinse aid cap is integrated into the assembly, so you won't need to save that separately.

Installation Overview

Replacing the dispenser requires accessing the inner door panel. You'll disconnect power, remove the door's inner panel screws, carefully detach the old dispenser's wiring connector, remove two mounting screws holding the dispenser in place, and reverse the process with the new unit. The trickiest part is aligning the dispenser so it sits flush with the door panel and doesn't interfere with the door closing mechanism. Budget 45-60 minutes if you're methodical and take photos during disassembly.

Why This Part Fails

Samsung's dispenser assemblies typically fail from one of three issues: heat stress from the drying cycle causing plastic warping, detergent residue jamming the actuator mechanism, or electronic component failure in the actuator motor itself. Hard water areas see faster failures because mineral deposits build up inside the rinse aid chamber and restrict the dispensing mechanism. Using non-HE or excessive detergent accelerates wear because extra suds create back-pressure when the door tries to open. The DW80M and DW80N series had some early production runs with actuator springs that were slightly undersized, leading to premature failures in the 3-5 year range.

Prevention Tips

After installing your new dispenser, you can extend its life by using only HE-rated detergent in the recommended amounts — usually one tablespoon of powder or one pod, not two. Run a cleaning cycle monthly with dishwasher cleaner to prevent buildup. For the rinse aid chamber, wipe away any spills immediately since dried rinse aid turns sticky and can gum up the dispenser valve. Don't slam the dishwasher door shut; the impact can stress the dispenser's mounting points over time.
