      🔧 Step 1: Check base pan for water accumulation

      1. Open the dishwasher door fully until it rests in the horizontal position.
      2. Pull out the bottom dish rack completely and set it aside on the floor or counter.
      3. Locate the circular filter assembly in the center of the dishwasher floor – it consists of a cylindrical mesh filter approximately 4 inches in diameter.
      4. Grasp the cylindrical filter and rotate it counterclockwise one-quarter turn (90 degrees) until it unlocks.
      5. Lift the cylindrical filter straight up and out of the sump area.
      6. Remove the flat fine filter screen beneath it – this is a rectangular piece measuring approximately 10 inches by 6 inches that sits loosely on the floor.
      7. Set both filter components aside in your sink.
      8. Look into the now-exposed sump opening – you’ll see a white plastic impeller blade at the bottom, approximately 2 inches below the dishwasher floor level.
      9. Use a flashlight to shine light into the sump cavity and inspect for any standing water, which indicates the base pan beneath may be flooded.
      10. Remove the lower spray arm by pulling it straight up off the center mount – it requires no unscrewing.
      11. Tip the dishwasher backward approximately 45 degrees by lifting from the front edge while a second person stabilizes from behind, OR pull the unit forward out of the cabinet space until you can access the front toe kick panel.
      12. Remove the toe kick panel by locating 2 Phillips-head screws at the bottom corners (one screw 2 inches from each side edge).
      13. Use a Phillips #2 screwdriver to remove both screws, then pull the toe kick panel forward and down to release it.
      14. Shine your flashlight into the base pan area beneath the dishwasher tub – you’re looking for any water pooling in the black plastic pan that sits under the stainless steel tub.
      15. Water present in the base pan indicates a leak and will trigger the float switch, preventing the dishwasher from running.

      🛠️ Step 2: Inspect door seal for damage or gaps

      1. Open the dishwasher door fully to 90 degrees until it rests in the horizontal position.
      2. Locate the rubber door gasket – a continuous gray or white loop running along the entire perimeter of the tub opening, approximately 0.75 inches wide.
      3. Start your inspection at the bottom left corner where the seal meets the tub lip.
      4. Run your index finger along the inside channel of the seal, moving right across the bottom section (approximately 24 inches). Feel for any sticky residue, food particles, or calcium buildup that could prevent proper sealing.
      5. Press the seal firmly against the tub edge every 4-6 inches. The seal should spring back immediately when released. If it stays compressed or feels brittle, note this location.
      6. Continue along the right vertical side (approximately 18 inches). Look for any visible gaps between the seal and the white or stainless tub edge – the seal should contact the tub continuously with no light visible through gaps.
      7. Check the top section (24 inches) where water pressure is highest. Look for three specific damage types: cracks (thin lines in the rubber), tears (split sections), or compression marks (permanent flat spots from the door pressing).
      8. Complete the inspection on the left vertical side (18 inches), returning to your starting point.
      9. Close the door slowly and observe the seal compression. With the door latched, the seal should compress uniformly by approximately 1/4 inch around the entire perimeter.
      10. Run your hand along the outside bottom edge of the closed door. You should feel no air movement or detect moisture from previous cycles.
      11. If you found cracks longer than 1/2 inch, tears of any size, gaps exceeding 1/8 inch, or sections that won’t compress, the seal requires replacement (Bosch part number 00754700 or equivalent).

      ⚙️ Step 3: Tighten all hose connections

      1. Locate the drain hose connection at the bottom rear left of the dishwasher, approximately 4 inches from the left side panel and 2 inches up from the base.
      2. Grip the ribbed plastic drain hose where it connects to the drain pump outlet (a white plastic fitting approximately 1.5 inches in diameter).
      3. Use groove-joint pliers with 10-inch handles to tighten the spring clamp securing the drain hose by squeezing the two tabs together and sliding the clamp 1/4 inch closer to the pump connection point.
      4. Move to the water inlet valve located at the bottom front right corner, 3 inches from the right edge and directly behind the toe kick panel.
      5. Identify the braided stainless steel supply line connected to the inlet valve’s threaded brass fitting (marked with a blue plastic cap on top).
      6. Use an adjustable wrench set to 7/8 inch to grip the brass hex nut connecting the supply line to the inlet valve.
      7. Turn the nut clockwise exactly 1/4 turn until it stops moving and feels snug against the valve body—you should feel resistance at approximately 15-18 ft-lbs of pressure.
      8. Check the circulation pump connection at the center bottom of the tub, where a black corrugated hose connects to the sump assembly.
      9. Verify the worm-gear clamp (a metal band with a screw mechanism) is positioned squarely on the ribbed section of the hose, approximately 1 inch from the pump connection.
      10. Use a 5/16-inch nut driver or flat-head screwdriver to turn the worm-gear clamp screw clockwise 2-3 full rotations until the hose compresses slightly and cannot be rotated by hand.
      11. Tug firmly on each hose connection with 10-15 pounds of pulling force—none should slide more than 1/8 inch from their connection points when properly secured.

      🔩 Step 4: Check for leaks around pump connections

      1. Locate the circulation pump in the sump area at the bottom center of the dishwasher tub, approximately 8 inches back from the front edge.
      2. Identify the three connection points on the pump assembly:
      3. Use a flashlight to inspect each connection point, looking for:
      4. Run your finger along the underside of each hose connection where it meets the pump, feeling for moisture or soft, swollen rubber.
      5. Check the inlet hose spring clamp (located at top left connection): verify it sits 0.25 inches from the end of the hose and maintains firm pressure – squeeze the clamp tabs with slip-joint pliers to test tension.
      6. Inspect the rubber gasket inside each hose connection by pulling the hose back 0.5 inches (loosen clamp first if needed) – the gasket should be black, pliable, and without cracks or flat spots.
      7. Examine the pump housing itself for hairline cracks, focusing on the seam where the white plastic pump body meets the black motor housing.
      8. Place a dry paper towel under each connection point, then run a rinse cycle for 3 minutes – immediately after cycle ends, check towels for dampness to identify active leaks.
      9. If leaks are present, mark the location with a grease pencil directly on the pump housing for repair reference.

      đź“‹ Step 5: Replace door seal or repair leaks as needed

      1. Open the dishwasher door fully to 90 degrees.
      2. Locate the existing door seal (rubber gasket) running along the entire perimeter of the tub opening—it sits in a channel approximately 1/4 inch deep.
      3. Starting at the top center of the door opening, grip the seal firmly and pull it straight out from the channel, working your way around the entire perimeter until completely removed.
      4. Use a damp cloth to wipe out the channel, removing any debris, old adhesive residue, or calcium buildup.
      5. Unpack the new door seal (Bosch part number 00686980) and identify the thicker portion—this is the top section.
      6. Starting at the top center, press the thicker portion of the new seal into the channel using your thumbs, pushing firmly until it seats completely into the groove with no gaps visible.
      7. Work your way down both sides simultaneously, pressing the seal into the channel in 3-4 inch sections, ensuring it sits evenly without twisting.
      8. At each bottom corner, press firmly to seat the seal around the curved radius—the seal should follow the channel smoothly without bunching.
      9. Complete installation across the bottom, stretching slightly if needed to eliminate any slack.
      10. Run your finger along the entire perimeter, pressing any loose sections until the seal sits uniformly in the channel.
      11. Close the door and inspect where the seal contacts the door face around the entire perimeter.
      12. If you see gaps larger than 1/16 inch between the seal and door, locate the 8 door latch mounting screws (4 on each side, accessed by opening the door) using a T20 Torx bit.
      13. Loosen each screw 1/4 turn, then close the door and tighten them to 18-20 inch-pounds, working in a star pattern to ensure even pressure.
      14. Test by running a rinse cycle and checking for leaks at floor level.
