Samsung Dishwasher Drain Hose Assembly Parts — Models & Compatibility

Samsung's DW80 series dishwashers share a common weak point: the drain hose assembly. If you're seeing water pooling under your dishwasher or hearing gurgling sounds during the drain cycle, this DD97-00403E replacement hose assembly is what Samsung techs install to fix it. This hub covers drain hose compatibility across Samsung's most popular dishwasher models from 2015 through 2023.

Is This the Right Part for Your Model?

Your model number is stamped on the inside edge of your dishwasher door — open it and look along the top or side frame. It'll start with "DW80" for most Samsung dishwashers using this hose. Double-check that your model appears in the compatibility list below before ordering, because Samsung uses different hose configurations for their DW60 and older DW70 series.

About This Replacement Part

The DD97-00403E is Samsung's updated drain hose assembly that supersedes the older DD97-00403A version. It's the complete assembly — you're getting the corrugated drain hose with both connection fittings already attached, so there's no need to hunt down additional clamps or adapters. The primary failure mode here is leaking, which typically happens where the hose connects to the pump housing or where it exits through the cabinet base. Over time, the rubber connections harden from heat cycles and detergent residue, causing small cracks that turn into puddles on your floor. This replacement restores the watertight seal your dishwasher needs to drain properly without flooding your kitchen.

Compatible Samsung Dishwasher Models

This drain hose assembly works across Samsung's DW80 dishwasher lineup, including their premium WaterWall and StormWash models. The models below all use the same DD97-00403E hose configuration:

• DW80H9970US — WaterWall series
• DW80J3020UB, DW80J3020US, DW80J3020UW — J-series basic models
• DW80J7550UG, DW80J7550US — J-series mid-range
• DW80K5050UB, DW80K5050UG, DW80K5050US, DW80K5050UW — K-series StormWash
• DW80K7050UG, DW80K7050US — K-series premium
• DW80M9550UG — M-series top-tier
• DW80R7061US, DW80R9950US — R-series latest generation

What You're Replacing

This isn't just a piece of rubber tubing. The assembly includes the main drain hose (about 6 feet long), the pump outlet connector that seals against your dishwasher's drain pump, and the cabinet exit fitting that routes water to your sink drain or garbage disposal. When you order DD97-00403E, you're getting everything needed to replace the entire drain path from pump to plumbing connection. No need to reuse old clamps or fittings — it's all included.

Why This Part Fails

Leaking is the telltale sign your drain hose needs replacement. The hose itself can develop pinhole leaks if it's been kinked or crushed against the cabinet frame, but more often the rubber connection points deteriorate first. Every wash cycle pushes hot water through these connections under pressure, and detergent residue accelerates rubber breakdown. After 5-7 years, even a hose that looks fine externally can have connection seals that are hard and brittle. You'll notice water under the dishwasher after cycles, or sometimes a slow drip that only appears during the drain phase.

Installation Overview

You'll need to pull your dishwasher out from under the counter to access the drain connections. The old hose twists off the pump outlet and disconnects from your sink drain connection under the cabinet. Route the new DD97-00403E hose the same way the old one ran — avoid sharp bends that could restrict drainage. Secure both ends firmly, then run a test cycle while the dishwasher is still pulled out so you can verify there's no leaking before pushing it back into place.

Cross-Reference Numbers

If you're cross-checking parts from a service manual or another supplier, this drain hose assembly has been sold under several different part numbers: DD97-00403A (the original version), along with generic reference numbers 113268, AP6981640, and PS12749174. They all refer to the same functional part, though DD97-00403E is Samsung's current production number and includes minor improvements to the connection fittings.
