📋 What You’ll Need

  • Upper spray arm support bearing
  • Water distributor seal

    • 🔧 Step-by-Step Repair Instructions

      🔧 Step 1: Inspect upper spray arm support bearing

      1. Open the dishwasher door fully until it rests horizontally at approximately 90 degrees from the closed position.
      2. Pull out the lower dish rack completely and set it aside on the floor or counter.
      3. Pull out the upper dish rack completely and set it aside with the lower rack.
      4. Locate the upper spray arm assembly mounted to the underside of the upper rack support rail, centered in the dishwasher tub approximately 18-20 inches from the door opening.
      5. Grip the upper spray arm firmly with both hands and rotate it counterclockwise while pulling downward with steady pressure until it detaches from the mounting hub (typically requires 1/4 to 1/2 turn).
      6. Look at the exposed spray arm mounting hub protruding downward from the water supply tube – you’ll see a white or gray cylindrical support bearing approximately 1 inch in diameter with a center hole.
      7. Place your index finger on the bearing surface and move it side-to-side and up-and-down to check for excessive play – movement greater than 1/16 inch indicates wear requiring replacement.
      8. Rotate the bearing clockwise and counterclockwise with your fingers – it should turn smoothly without grinding, catching, or resistance.
      9. Run your fingertip around the inner edge of the bearing hole checking for rough spots, cracks, or missing plastic pieces that feel like notches or gaps.
      10. Examine the bearing for discoloration – brown, orange, or white mineral deposits indicate water leakage past worn seals.
      11. Check the rubber or silicone O-ring seal at the base of the bearing housing for flat spots, cracks, or hardening by pressing it with your fingernail – it should compress and spring back.
      12. If the bearing shows any excessive movement, rough rotation, visible damage, or seal deterioration, replacement is necessary using the appropriate bearing assembly kit for your dishwasher model number.

      🛠️ Step 2: Check water distributor seal

      1. Locate the water distributor assembly at the top of the dishwasher tub, directly beneath the upper spray arm mounting point in the center of the ceiling.
      2. Remove the upper spray arm by turning it counterclockwise 90 degrees and pulling straight down to release it from the distributor mount.
      3. Use a Phillips-head screwdriver #2 to remove the 3 screws securing the distributor cover plate, positioned in a triangular pattern approximately 2 inches from the center point.
      4. Pull the distributor cover straight down to expose the water distributor chamber and seal assembly.
      5. Examine the rubber seal ring (typically black or gray, measuring approximately 3 inches in diameter) seated in the circular groove around the distributor inlet pipe.
      6. Run your finger completely around the seal’s circumference, feeling for these specific defects:
      7. Check for mineral deposits or white calcium buildup on the seal surface by scraping gently with your fingernail.
      8. Verify the seal sits flush in its groove with no raised or lifted sections—the top surface should be level with the surrounding plastic housing edge.
      9. If the seal shows cracks, hardening, or compression damage, grip it at any point and pull upward and outward to remove it from the groove.
      10. Clean the seal groove using a cloth dampened with white vinegar to remove mineral deposits and residue.
      11. Install the new seal (part number W10195677 for most models) by pressing it into the groove, starting at the 12 o’clock position and working around clockwise until the entire circumference seats completely in the channel.
      12. Confirm the seal sits evenly with no twisted or overlapping sections—you should see consistent rubber height around the entire circle.

      ⚙️ Step 3: Test spray arm rotation

      1. Open the dishwasher door fully until it rests horizontally at a 90-degree angle from the cabinet.
      2. Pull out the bottom dish rack completely and set it aside on your workspace.
      3. Locate the lower spray arm at the center bottom of the tub—it’s a plastic propeller-shaped component typically 6-8 inches in diameter with multiple water jets angled at 45 degrees.
      4. Grasp the spray arm hub (the center raised portion) with your hand and attempt to rotate it clockwise, then counterclockwise—it should spin freely 360 degrees with minimal resistance, making approximately 2-3 full rotations before stopping naturally.
      5. If the spray arm doesn’t spin freely, remove it by pulling straight up on the hub or unscrewing the center cap counterclockwise (depending on your model’s design)—most lift off with 2-3 pounds of upward force.
      6. Inspect the spray arm mounting hub underneath where the arm sits—you’ll see a cylindrical post approximately 0.5-1 inch tall with a diameter of 0.75 inches.
      7. Look for food debris, mineral deposits, or broken plastic pieces around the mounting post and inside the spray arm center hole.
      8. Clear any obstructions using your fingers or a toothpick.
      9. Reinstall the spray arm by aligning the center hole over the mounting post and pressing down or threading the cap clockwise until it seats flush against the tub bottom.
      10. Spin the spray arm again—it should now rotate with smooth, continuous motion requiring only light finger pressure to initiate movement.
      11. Repeat steps 2-10 for the upper spray arm, which you’ll find by looking up at the underside of the top rack—it’s mounted to the center of the tub ceiling.
      12. Leave both racks removed for the next testing step.

      🔩 Step 4: Replace bearing assembly

      1. Lift the outer tub assembly and flip it upside down on your work surface so the bearing housing faces upward.
      2. Locate the large circular bearing housing in the center of the outer tub – it’s typically 8-10 inches in diameter with a silver or bronze metal ring visible.
      3. Position a flat-head screwdriver (5/16-inch wide blade) between the outer bearing race and the tub housing at the 12 o’clock position.
      4. Strike the screwdriver handle firmly with a rubber mallet using controlled hits until the bearing race begins to lift approximately 1/4 inch.
      5. Move clockwise to the 3 o’clock position and repeat the striking process, then continue to 6 o’clock and 9 o’clock positions.
      6. Continue rotating and striking around the entire circumference until the outer bearing race pops free from the housing – you’ll hear a distinct metallic ring when it releases.
      7. Remove the bearing race completely and set aside.
      8. Clean the bearing seat cavity using a wire brush attachment on a drill, removing all rust, detergent residue, and old grease.
      9. Wipe the cavity with a rag dampened with degreaser until the metal surface appears uniformly clean.
      10. Apply a continuous 1/8-inch bead of marine-grade sealant around the entire circumference of the bearing seat.
      11. Place the new bearing assembly (verify the part number stamped on the bearing matches your model’s requirement) into the housing with the sealed side facing down into the tub.
      12. Position a bearing installation tool or a section of 2×4 lumber (8 inches long) flat against the outer bearing race.
      13. Strike the wood evenly with a rubber mallet, rotating around the bearing circumference every 3-4 hits.
      14. Continue until the bearing seats flush with the housing surface – no gap should be visible between the bearing edge and tub housing.
      15. Allow sealant to cure for 2 hours before proceeding to shaft installation.

      đź“‹ Step 5: Replace water distributor seal if damaged

      1. Lift the water distributor assembly up and out of the dishwasher tub – it will separate from the base where the seal sits.
      2. Locate the rubber seal on the bottom of the distributor housing – it’s a black O-ring style gasket approximately 2 inches in diameter sitting in a circular groove.
      3. Insert a flat-head screwdriver (4mm width) under one edge of the old seal and pry it up and out of the groove. Work around the circumference until the entire seal releases.
      4. Clean the seal groove using a clean cloth dampened with white vinegar, removing all mineral deposits, food particles, and old lubricant residue. The groove should appear smooth and uniform.
      5. Unwrap the new seal (common part numbers: WD01X10134, 5304506469, or DD81-01629A depending on your model) and wipe it down with a dry cloth to remove any packaging oils.
      6. Apply a thin bead of food-grade silicone grease (approximately 1/8 inch wide) around the entire circumference of the seal – this aids installation and creates proper compression.
      7. Position one section of the new seal into the groove at the 12 o’clock position, then use your thumbs to press and roll the seal into the groove working clockwise and counterclockwise simultaneously until the entire seal seats evenly.
      8. Run your finger around the installed seal – it should sit flush in the groove with no twisted sections or raised areas protruding more than 1/8 inch above the groove surface.
      9. Lower the water distributor assembly back into position in the dishwasher tub, aligning the center shaft with the mounting hole at the bottom center of the tub.
      10. Press down firmly until the distributor sits flat – you should feel resistance as the new seal compresses, creating a watertight connection between the distributor and tub base.
