      🔧 Step 1: Remove and clean filter assembly

      1. Open the dishwasher door completely until it rests horizontally.
      2. Pull out the lower dish rack entirely and set it aside on the floor or counter.
      3. Locate the cylindrical filter assembly in the center of the dishwasher floor, approximately 10 inches from the front door edge.
      4. Identify the three-part filter system: the outer cylindrical mesh filter (approximately 4 inches diameter), the inner fine mesh filter, and the flat circular filter plate beneath.
      5. Grasp the outer cylindrical filter at the top rim with your dominant hand.
      6. Turn the cylindrical filter counterclockwise one-quarter turn (90 degrees) until it stops rotating.
      7. Lift the cylindrical filter straight up and out of the basin—it will come out as one piece with the inner fine filter attached.
      8. Separate the inner fine filter from the outer cylinder by pulling them apart with both hands.
      9. Lift out the flat circular filter plate from the dishwasher floor by grasping its edge and pulling upward—no twisting required.
      10. Rinse all three filter components under warm running water (120-140°F) for 30 seconds each to remove loose debris.
      11. Apply 2-3 drops of liquid dish soap to a soft-bristled brush (toothbrush works well).
      12. Scrub the mesh surfaces of both cylindrical filters using circular motions, spending 15-20 seconds on each section.
      13. Scrub both sides of the flat filter plate, paying attention to the perforated holes.
      14. Rinse all three components under warm running water for 20 seconds each until no soap residue remains and water runs clear through the mesh.
      15. Shake each component 3-4 times to remove excess water.
      16. Insert the flat circular filter plate back into the dishwasher floor basin, seating it flush with the surrounding surface.
      17. Align the inner fine filter inside the outer cylindrical filter.
      18. Place the assembled cylindrical filter into the center opening, aligning the arrow or tab marking on the filter with the corresponding mark in the basin.
      19. Turn clockwise one-quarter turn (90 degrees) until you feel it lock into place—the filter should sit flush and not wiggle when touched.

      🛠️ Step 2: Clean sump area thoroughly

      1. Locate the sump assembly at the bottom center of the dishwasher tub – it’s the circular or oval-shaped depression approximately 8 inches in diameter where water collects during the wash cycle.
      2. Remove the cylindrical filter assembly by grasping it and turning counterclockwise 1/4 turn, then lifting straight up and out of the sump.
      3. Look inside the now-exposed sump chamber and locate the chopper blade (a plastic propeller-like component approximately 3 inches in diameter) at the bottom.
      4. Use a wet/dry vacuum with a crevice attachment to extract all standing water from the sump – insert the nozzle down into the chamber until it reaches the bottom.
      5. Remove any visible food particles, broken glass, or debris from the sump using needle-nose pliers to reach down and extract items.
      6. Mix 2 cups of warm water with 2 tablespoons of dish soap in a container.
      7. Dip a stiff-bristled brush (like a toothbrush or detail brush) into the soapy water and scrub the inside walls of the sump chamber in circular motions, working from top to bottom.
      8. Scrub around and underneath the chopper blade – move the blade manually with your fingers to access all surfaces beneath it.
      9. Check the sump screen (a perforated metal or plastic disc at the very bottom) for clogs by looking through the holes – they should be completely clear.
      10. Use a straightened paperclip or toothpick to clear any blocked holes in the sump screen by pushing through from top to bottom.
      11. Flush the sump by pouring 1 cup of clean water into it while the vacuum is running at the bottom to extract the dirty rinse water.
      12. Repeat the flushing process until the extracted water runs clear with no debris.
      13. Wipe the rim of the sump opening with a clean microfiber cloth to remove any remaining residue.

      ⚙️ Step 3: Check drain hose for kinks or blockages

      1. Open the dishwasher door fully and remove the lower dish rack by lifting it straight up and out.
      2. Locate the drain hose connection point at the rear left corner of the dishwasher tub, approximately 2 inches from the bottom.
      3. Use a flashlight to trace the corrugated gray drain hose from its connection point toward the back of the unit.
      4. Close the dishwasher door and pull the unit forward 12-18 inches to access the rear panel area. You may need a second person to support the weight.
      5. Look underneath the dishwasher at the drain hose routing. The hose runs from the left side of the pump assembly toward the right rear corner, then loops upward before exiting through the cabinet.
      6. Run your hand along the entire length of the drain hose, feeling for any sharp bends, pinch points, or crushed sections. A proper bend has a radius of at least 2 inches—anything tighter indicates a kink.
      7. If you find a kinked section, gently straighten it by repositioning the hose clamp (if present) or adjusting how the hose routes through the space.
      8. Disconnect the drain hose from the sink tailpiece or garbage disposal connection (typically secured with a hose clamp requiring a flathead screwdriver or 5/16-inch nut driver).
      9. Hold the disconnected end over a bucket or shallow pan.
      10. Pour 2 cups of water into the drain hose at the dishwasher end. Water should flow freely through and exit within 3-5 seconds.
      11. If water backs up or drains slowly, insert a drain snake or straightened wire coat hanger into both ends of the hose, pushing through any debris accumulation.
      12. Flush the hose again with 4 cups of hot water until it flows clear and unobstructed.
      13. Reconnect the drain hose to the disposal or sink tailpiece, positioning the hose clamp 1/4 inch from the end and tightening until snug but not overtightened.

      🔩 Step 4: Test drain pump operation

      1. Locate the drain pump assembly at the bottom center of the dishwasher tub, directly below the filter housing where you can see the black circular pump housing with the white impeller cover.
      2. Restore power to the dishwasher by flipping the circuit breaker back to the ON position or plugging the unit back into the wall outlet.
      3. Close the dishwasher door and press the power button on the control panel.
      4. Press and hold the “Start” button and the “>” button simultaneously for 3-5 seconds to enter diagnostic mode—the display will show “0:01” when successful.
      5. Press the “>” button repeatedly until the display shows “0:03″—this is the drain pump test cycle.
      6. Press “Start” to activate the drain pump.
      7. Listen for the pump motor engaging—you should hear a steady humming sound coming from the bottom center of the unit, lasting approximately 60 seconds.
      8. Open the door during operation and visually confirm the white impeller inside the pump housing is rotating counterclockwise when viewed from above.
      9. Place your hand near the drain hose connection point at the back right side of the unit (under the sink, typically 18-24 inches from the floor) and feel for water pulsing through the hose—this confirms water is being pumped out.
      10. Watch for water draining from the dishwasher tub—the standing water should completely evacuate within 60-90 seconds.
      11. Press “Cancel” or “Reset” to exit diagnostic mode when the drain cycle completes.
      12. If the pump runs but no water drains, the impeller is blocked or the pump housing has internal damage requiring pump replacement (part number 00642239).
      13. If the pump does not run at all, verify the electrical connector is fully seated, then replace the drain pump assembly.
      14. Turn off power at the circuit breaker before proceeding to Step 5.

      đź“‹ Step 5: Replace drain pump if not operating properly

      1. Locate the drain pump at the bottom center of the dishwasher tub, directly beneath the filter assembly opening.
      2. Disconnect the single wire harness from the pump motor by pressing the locking tab on the white plastic connector and pulling straight away from the pump body.
      3. Use needle-nose pliers to squeeze the hose clamp on the drain hose (right side of pump) and slide it 2 inches away from the pump outlet.
      4. Twist and pull the corrugated drain hose off the pump outlet barb – expect residual water to drain out (approximately 1/4 cup).
      5. Locate the inlet hose on the left side of the pump and repeat the clamp removal: squeeze the spring clamp with pliers, slide it back 2 inches, then twist and remove the hose from the inlet barb.
      6. Remove the three T20 Torx screws securing the pump assembly to the sump housing – one at the front center and two on the sides, spaced 3 inches apart.
      7. Rotate the entire pump assembly counterclockwise 1/4 turn (90 degrees) to release it from the bayonet mounting tabs in the sump.
      8. Lift the pump straight up and out of the sump housing.
      9. Position the new pump (Bosch part #00611332) into the sump opening, aligning the two tabs on the pump base with the slots in the sump housing.
      10. Rotate the pump clockwise 1/4 turn until it stops – you’ll feel it lock into place.
      11. Install the three T20 Torx screws, tightening each in a star pattern to finger-tight plus 1/4 turn.
      12. Push the inlet hose onto the left barb until it bottoms out (insert 1 inch deep), then slide the spring clamp back over the connection point.
      13. Push the drain hose onto the right barb until fully seated, then reposition and release the hose clamp over the connection.
      14. Reconnect the white wire harness connector until you hear a distinct click.
