How to Replace DD97-00403E Drain Hose Assembly on Samsung Dishwasher — Step-by-Step

You notice water pooling under your Samsung dishwasher after every cycle. You trace it back to the drain hose connection — it's cracked where the ribbed section meets the pump housing. This is the DD97-00403E drain hose assembly failing, and it's common on models like the DW80K5050US and DW80J7550UG after a few years of use. The good news? You can replace it yourself in under an hour without calling a tech.

What You Need Before Starting

This repair requires minimal tools and can be done by most DIYers. Here's what to have ready:

• Phillips head screwdriver
• Towels or shallow pan for water
• Flashlight
• Pliers (optional, for stubborn clamps)

Estimated Time: 45-60 minutes
Difficulty: MODERATE

Safety First

Warning: Always disconnect power at the breaker before working on your dishwasher. Water and electricity don't mix. Also shut off the water supply valve under your sink — even though we're working on the drain side, you don't want any surprises if you bump a supply line.

Step 1: Access the Lower Front Panel

Open the dishwasher door and locate the screws along the top edge of the lower access panel (the kickplate at the bottom). Remove these screws and gently pull the panel forward and down to release it. Set it aside. You'll now see the drain pump and hose connections underneath.

Step 2: Locate and Disconnect the Old Drain Hose

The DD97-00403E connects from the drain pump on the left side and routes to the sink drain or garbage disposal. Place towels under the connections — there's always residual water. Squeeze the spring clamps at both ends of the hose (one at the pump, one at the drain outlet) and slide them back. Twist and pull the hose off both connections. Expect a bit of dirty water to drain out.

Step 3: Remove the Hose from Its Routing Clips

Follow the hose path and you'll find it's held by several plastic clips along the dishwasher's base. Gently press the clip tabs and slide the old hose out. Don't force it — if a clip breaks, they're cheap to replace but annoying. Take a quick photo of the routing path before removing the hose completely so you remember how it snakes through.

Step 4: Install the New DD97-00403E Assembly

Route your new hose through the same clips you just freed the old one from. Start at the pump end and work toward the drain outlet. Make sure the hose has a high loop (rises above the connection point) before dropping down to the drain — this prevents backflow. Push the hose firmly onto both the pump outlet and drain connection until they seat completely. Slide the spring clamps forward over the connection points and make sure they click into the groove.

Step 5: Test for Leaks

Don't button everything up yet. Turn the water supply back on and restore power at the breaker. Run a short rinse cycle and watch the connections with your flashlight. Check both ends of the hose and all the routing points. If you see any moisture, tighten the clamp or reseat that connection. Once you're confident it's dry, reinstall the lower access panel.

Testing After Installation

Run a full normal cycle with dishes in the washer. Check underneath one more time after completion. Listen for the drain pump — it should sound smooth, not labored. Your floor should stay completely dry. If the dishwasher drains slowly or you still see leaking, double-check that both hose ends are fully seated and the clamps are positioned correctly in the grooves.

Frequently Asked Questions

Will this DD97-00403E hose fit my DW80J3020US model?

Yes, the DD97-00403E is compatible with the entire DW80J3020 series (UB, US, UW variants) as well as DW80K5050, DW80K7050, DW80R7061US, and many other Samsung models. It replaces the older DD97-00403A part number. Check your model against the compatibility list to be certain.

Why do these drain hoses crack in the first place?

The ribbed section near the pump connection flexes constantly during drain cycles, and the combination of hot water, detergent residue, and vibration degrades the rubber over time. If your dishwasher is 3-5 years old and leaking from this area, it's usually this hose. The material just fatigues.

Can I use a generic drain hose instead of the Samsung part?

I wouldn't recommend it. The DD97-00403E has specific bends, length, and diameter that match Samsung's pump output and routing clips. A generic hose might fit the connections but won't route properly or could restrict flow, making your pump work harder. Spend the money on the OEM-quality part — it'll last another 5 years.
