Samsung DW80J3020US/AA-00 dishwasher Parts

The Samsung DW80J3020US dishwasher is a standard 24-inch built-in model. Its overall cabinet dimensions are 23 7/8 in. wide x 24 1/2 in. deep x 33 7/8 in. high, which helps you confirm fit in a typical under-counter dishwasher opening (see the DW80J3020US user manual).

Here are the published overall dimensions for this exact Samsung dishwasher model:

Even with a standard 24-inch dishwasher, we recommend measuring your space and connections so the unit sits level and the door clears properly.

• Measure the cabinet opening width at the front and back
• Measure height from floor to underside of countertop (check for tile thickness)
• Measure depth to confirm the door can open fully
• Confirm the unit can be leveled (front-to-back and side-to-side)
• Check that the water line and drain hose routing will not kink when pushed in

Dishwasher “size” is often used two ways: the nominal class (24-inch built-in) and the actual cabinet dimensions. Using the DW80J3020US dimensions helps prevent installation issues like rubbing doors, poor leveling, vibration/noise, and leaks from strained hoses.

If you are troubleshooting after installation (for example, long cycles or blinking lights), our Samsung dishwasher error codes guide can help you match symptoms to likely causes.

If your Samsung DW80J3020US dishwasher won’t start, the most common causes are a door that isn’t fully latched, Control Lock being turned on, no cycle being selected, or a power or water supply issue. We recommend following the start sequence in the DW80J3020US user manual.

• Close and latch the door firmly; the dishwasher will not run if the latch is not engaged.
• Press START before closing the door (this model can require START first, then door close).
• Make sure Control Lock is off (hold Sanitize for 3 seconds to toggle).
• Select a cycle (Auto, Normal, Heavy, Quick+) before pressing START.
• Confirm power: the unit is on, the plug is seated, and the breaker is not tripped.
• Confirm water: the supply valve is open and the line is not kinked.

On DW80J3020US, “information codes” can show as blinking cycle selector lights. If you see blinking patterns, use the Samsung dishwasher error codes reference to match the pattern to a likely cause (water supply check, leak check, high temp heating check, etc.).

A dishwasher that won’t start is often protecting you from running with an unlatched door, locked controls, or no water supply. Fixing the root cause prevents mid-cycle stops, drain issues, and error codes.

To clean your Samsung DW80J3020US dishwasher, we recommend wiping the interior and door, cleaning the spray nozzles if wash performance drops, and running an empty cleaning cycle (Normal with Sanitize) to remove buildup and odors. Follow the steps in the DW80J3020US user manual.

• Turn off power at the control panel; let the unit cool if it just finished a hot cycle.
• Remove dishes and check the bottom of the tub for debris.
• Wipe the inner door, door edges, and tub with a damp cloth.
• Clean the exterior with a soft damp cloth; avoid harsh chemicals on the control panel.
• Run an empty cycle periodically to freshen the interior.

Our model-specific guidance for DW80J3020US is:

• Fill the detergent dispenser and run Normal with the Sanitize option.
• If white spots or odor remain: run Normal empty and without detergent until it drains, then pause and place 8 oz of white vinegar in a cup on the lower rack and let the cycle finish.

If the dishwasher is leaving food behind, the spray nozzles can be clogged.

• Lower nozzle: pull upward to remove, rinse holes, reinstall, then rotate by hand to confirm it seats.
• Middle nozzle: remove the upper rack, remove the nut, clean, reinstall, and hand-tighten the nut.
• Upper nozzle: remove the cap by turning counterclockwise, clean, reinstall, then tighten the cap.

Keeping the DW80J3020US clean helps it wash and dry better, reduces odors, and can prevent clogs that lead to draining or cleaning problems.

For troubleshooting after cleaning (for example, if you see blinking lights or an information code), use our Samsung dishwasher error codes guide.

On the Samsung DW80J3020US dishwasher, we typically find the model number on the rating label located just inside the door opening, along the inner edge of the tub (commonly on the left side). That same label usually lists the serial number too.

Check these common spots in this order:

• Open the dishwasher door and look along the inner left side of the tub opening
• Check the top edge of the tub opening (near the door latch area)
• Check the inner right side of the tub opening if you do not see it on the left
• Look for a rectangular sticker or metal plate labeled “Model” and “Serial”

The rating label usually includes:

• Model number (example format: DW80J3020US)
• Version code (often shown after a slash, such as DW80J3020US/AA)
• Serial number
• Electrical ratings (volts/amps) and other specifications

Samsung dishwashers often use a version code (like “/AA”) that can change which parts fit. Using the full model and version from the label helps us match the correct dishwasher parts and troubleshooting info the first time.

For diagrams and model identification details specific to this unit, use the DW80J3020US manual.
