      🗑️

      🔧 Step 1: Remove pump filter

      1. Unplug the washing machine power cord from the wall outlet to cut all electrical power to the unit.
      2. Turn off both hot and cold water supply valves located behind the washer by rotating them clockwise until they stop.
      3. Locate the small rectangular access panel at the bottom front of the washer, positioned 2-3 inches from the left corner and approximately 1 inch above the floor.
      4. Insert a flat-head screwdriver into the small slot or notch at the right edge of this access panel.
      5. Pry the access panel forward gently until it releases from its clips, then pull it completely off and set it aside.
      6. Place 2-3 bath towels on the floor directly in front of the now-exposed pump filter area to catch approximately 1-2 cups of water that will drain out.
      7. Position a shallow container (like a 9×13 inch baking pan) on top of the towels, pushed against the washer base to catch water drainage.
      8. Identify the round black pump filter cap, which is a circular disc approximately 3 inches in diameter with raised grip ridges around its perimeter.
      9. Grip the filter cap firmly with your dominant hand using the raised ridges for traction.
      10. Rotate the filter cap counterclockwise (left) approximately one full rotation until it stops turning and loosens from its housing.
      11. Continue pulling the filter straight outward while maintaining the counterclockwise rotation until water begins flowing into your catch pan.
      12. Once water flow slows to a drip (after 15-30 seconds), pull the filter completely out of its circular housing.
      13. Set the filter aside on the towels where you can inspect it for debris, lint, coins, or small clothing items trapped in its mesh screen.

      🛠️ Step 2: Clear debris from pump

      1. Locate the pump filter access panel at the bottom right corner of the washer’s front face, approximately 4 inches from the right edge and 2 inches from the floor.
      2. Insert a flathead screwdriver into the slot at the top of the access panel cover and pry it open toward you. The panel will hinge downward.
      3. Pull the small black drain hose (approximately 6 inches long) from its holder clip on the left side of the opening.
      4. Place a shallow pan or towels on the floor directly under the hose opening to catch residual water (expect 1-2 cups).
      5. Twist the drain hose cap counterclockwise and remove it. Allow all water to drain completely into your pan.
      6. Replace the drain hose cap by twisting clockwise until snug, then return the hose to its holder clip.
      7. Grip the large circular pump filter cover (black plastic, approximately 4 inches in diameter) located in the center of the opening.
      8. Turn the filter cover counterclockwise while pulling outward. It will rotate approximately one full turn before releasing from the housing.
      9. Remove any visible debris from the filter screen—look for coins, buttons, hair ties, lint clumps, and small fabric pieces. Run your fingers around all edges of the circular filter.
      10. Insert your index and middle fingers into the now-exposed pump housing cavity and sweep around the entire interior perimeter in a circular motion.
      11. Remove any debris found inside the housing, including lint, small objects, and buildup on the impeller blades (you’ll feel 3 flexible rubber blades that should rotate freely).
      12. Rotate the impeller blades with your finger—they should spin smoothly without resistance or grinding sounds. This confirms proper pump operation.
      13. Thread the pump filter back into the housing by turning clockwise until hand-tight and fully seated against the rubber gasket. The filter arrow should point upward when properly installed.

      ⚙️ Step 3: Check impeller for damage

      1. Look down into the bottom of the stainless steel drum where you removed the rotor assembly in the previous step – you’ll see the white plastic impeller with three curved fins protruding upward from the center of the tub base.
      2. Run your fingers along each of the three impeller fins, checking for any cracks, chips, or broken pieces – the fins should feel smooth and continuous with no gaps or rough edges.
      3. Grip each fin firmly and attempt to move it side-to-side and up-and-down – there should be zero movement; any wobble or play indicates a damaged mounting point requiring impeller replacement (part number DC97-21808A).
      4. Examine the top surface of each fin for wear grooves or deep scratches deeper than 1/8 inch – minor surface scratches are acceptable, but deep grooves that span more than 50% of the fin width mean the impeller cannot move water effectively.
      5. Check the center hub where the impeller connects to the stator below – look for any circular cracks radiating outward from the center bolt hole, which indicate stress fractures.
      6. Spin the impeller clockwise with your hand – it should rotate freely with minimal resistance and make a smooth swooshing sound without any grinding, clicking, or scraping noises.
      7. Look at the underside of each fin using a flashlight, angling it to see underneath – check for any broken mounting tabs or separation where the fins connect to the center hub.
      8. If you found any cracks, significant chips, wobbling, or deep wear grooves exceeding 1/8 inch depth, you need to replace the impeller assembly before proceeding – if the impeller passed all checks, continue to Step 4.

      Step 4.

      🔩 Step 4: Clean pump housing

      1. Locate the pump housing, which is the white or gray plastic chamber directly behind where the drain pump was mounted at the lower right front of the machine.
      2. Use a Phillips-head screwdriver #2 to remove the 2 screws (one at the top, one at the bottom) securing the pump housing cover if your model has a separate cover piece.
      3. Pull the pump housing cover straight toward you to expose the impeller chamber inside.
      4. Shine a flashlight into the circular impeller chamber (approximately 3 inches in diameter) and look for debris, coins, buttons, hair clumps, or fabric fibers.
      5. Reach into the chamber with your fingers and manually rotate the impeller blades clockwise 2-3 full rotations to check for obstructions that prevent smooth spinning.
      6. Remove any visible debris by hand, pulling items straight out through the opening.
      7. Dip an old toothbrush into a mixture of 1 cup warm water and 2 tablespoons white vinegar.
      8. Scrub the interior walls of the pump housing using circular motions, paying attention to the grooved seal area where the pump connects (approximately 0.5 inches deep around the perimeter).
      9. Clean the impeller blades by scrubbing each of the 6 individual blades with the toothbrush, removing any buildup or residue.
      10. Wipe the housing interior with a clean microfiber cloth, removing all loosened debris and cleaning solution.
      11. Inspect the rubber gasket seal on the pump housing opening (the black O-ring approximately 2.5 inches in diameter) for cracks, tears, or hardening.
      12. If the gasket appears damaged, pry it out of its groove using a flat-head screwdriver and replace it with a new gasket (part number DC64-03203A).
      13. Rotate the impeller blades again—they should now spin freely with no grinding sensation or resistance when turned by hand.

      đź“‹ Step 5: Reinstall and test drainage

      1. Position the drain pump assembly back into its mounting bracket at the bottom right corner of the washer cabinet, approximately 4 inches from the front panel and 3 inches from the right side.
      2. Insert the two 8mm hex bolts through the pump mounting holes and hand-tighten them first, then secure with an 8mm socket wrench, tightening each bolt 3-4 full rotations until the pump housing sits flush against the bracket without gaps.
      3. Slide the ribbed drain hose onto the pump outlet (the larger diameter fitting on the pump’s right side) until it covers 2 inches of the outlet pipe.
      4. Position the spring clamp over the hose connection with the clamp’s screw mechanism facing upward for access, then tighten the clamp screw with a flat-head screwdriver until the clamp compresses visibly into the hose ridges—approximately 5-6 clockwise turns.
      5. Reconnect the white 2-wire electrical connector to the drain pump motor by aligning the connector’s tab with the slot on the pump terminal and pushing until you hear a distinct click.
      6. Run the drain hose to the standpipe or laundry sink, securing it at a height between 30-40 inches from the floor—this prevents siphoning during fills.
      7. Restore power to the washer by plugging it into the wall outlet.
      8. Select the “Rinse + Spin” cycle on the control panel and press Start.
      9. Pour 1 gallon of water directly into the drum through the door opening.
      10. Listen for the drain pump to activate within 30 seconds—you’ll hear a distinct humming sound and see water flowing through the clear drain hose section.
      11. Verify water drains completely within 2-3 minutes by checking the drum is empty and no water pools at the bottom.
      12. Check all hose connections for moisture or dripping by running your hand along each joint while the pump operates.
