📋 What You’ll Need

  • Drain pump
  • Cleaning tools

    • 🔧 Step-by-Step Repair Instructions

      🔧 Step 1: Check drain pump operation

      1. Turn off the circuit breaker that powers your dishwasher at the main electrical panel.
      2. Open the dishwasher door fully until it rests in the horizontal position.
      3. Remove the bottom dish rack by lifting it straight up and out of the tub.
      4. Locate the circular filter assembly in the center bottom of the tub and twist it counterclockwise approximately 90 degrees, then lift it straight up to remove it.
      5. Remove the rectangular fine filter screen underneath by pulling it straight up.
      6. Look into the sump area where the filters were seated—you’ll see a circular white plastic cover approximately 4 inches in diameter with a center hub.
      7. Grasp the center hub of this cover and rotate it counterclockwise one-quarter turn, then lift the entire chopper blade assembly straight up and set it aside.
      8. Shine a flashlight into the now-exposed sump opening—the drain pump impeller sits at the bottom, appearing as a white plastic propeller with 6-8 blades.
      9. Use needle-nose pliers to remove any visible debris, food particles, or objects blocking the impeller (common items include toothpicks, fruit pits, and small utensils).
      10. Manually rotate the impeller clockwise with your finger—it should spin freely with slight resistance. If it binds, catches, or won’t rotate at all, the pump motor is likely seized.
      11. Restore power at the circuit breaker and close the dishwasher door.
      12. Start a rinse cycle and listen for the drain pump motor—it activates approximately 10-15 seconds after starting the cycle and produces a low humming sound for 60-90 seconds.
      13. If you hear clicking, grinding, or no sound at all during this drain phase, the pump motor has failed and requires replacement (part number 154844301).
      14. If the pump runs smoothly and water drains from the tub, the drain pump is functioning correctly.

      🛠️ Step 2: Inspect drain hose for kinks or clogs

      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 bottom left rear corner of the tub interior, approximately 3 inches from the left edge and 2 inches from the back wall.
      3. Close the dishwasher door and pull the unit forward approximately 12 inches away from the wall to access the rear panel.
      4. Look behind the dishwasher to identify the corrugated gray or black drain hose (1.5 inches in diameter) that exits from the left side of the unit and runs upward toward the sink drain or garbage disposal.
      5. Trace the entire length of the drain hose from the dishwasher to its connection point under the sink, checking for:
      6. Straighten any kinked sections by gently repositioning the hose into a smooth curve with no angles sharper than 90 degrees.
      7. Disconnect the drain hose from the garbage disposal or sink drain tailpiece by loosening the hose clamp with a 5/16-inch nut driver, turning counterclockwise 3-4 full rotations.
      8. Pull the hose end free and hold it over a bucket or towel (expect 1-2 cups of standing water to drain out).
      9. Inspect inside the hose opening with a flashlight, looking for food particles, grease buildup, or standing water that doesn’t drain completely.
      10. Insert a straightened wire coat hanger or drain snake into both ends of the hose, pushing through any blockages until the wire passes freely through the entire length.
      11. Flush the hose by running hot tap water through it for 30 seconds until water flows clear and unobstructed from the opposite end.

      ⚙️ Step 3: Clean filter assembly

      1. Locate the cylindrical filter assembly at the bottom center of the dishwasher tub, directly beneath where the lower spray arm sits.
      2. Grip the outer cylindrical filter (approximately 4 inches in diameter) and rotate it counterclockwise one-quarter turn until it releases from the locked position.
      3. Lift the cylindrical filter straight up and out of the dishwasher tub, removing it completely.
      4. Grasp the flat, fine mesh filter screen (approximately 6 inches by 4 inches) located directly beneath where the cylindrical filter was positioned.
      5. Lift the fine mesh filter up at a 45-degree angle, tilting it toward the back of the dishwasher to disengage the rear tabs, then pull it forward and out.
      6. Look inside the now-exposed filter housing and locate any large food debris or objects, removing them by hand.
      7. Carry both filter components to your kitchen sink.
      8. Hold the cylindrical filter under warm running water (110-120°F) and use a soft-bristled dish brush to scrub the mesh openings from the inside out, working in circular motions.
      9. Flip the cylindrical filter and repeat the brushing process on the outer mesh surface, paying attention to the bottom perforated plate.
      10. Hold the fine mesh filter under warm running water and brush both sides using straight strokes parallel to the mesh pattern, removing all visible food particles and grease buildup.
      11. Inspect both filters under good lighting—the mesh openings should appear clear with no blockages visible when held up to light.
      12. Return to the dishwasher and wipe the exposed filter housing area with a damp cloth, removing any accumulated debris from the sump area.
      13. Position the fine mesh filter back into the tub floor, inserting the rear tabs first at a 45-degree angle, then pressing the front edge down flat until it sits flush.
      14. Place the cylindrical filter into the center opening, aligning the arrow marking on the filter with the arrow on the housing, then rotate clockwise one-quarter turn until it locks into place with resistance.

      🔩 Step 4: Verify dishwasher installation height

      1. Locate your measuring tape and position yourself directly in front of the open dishwasher door.
      2. Measure from the floor to the top edge of the dishwasher’s top panel where it meets the underside of your countertop. The correct installation height for the FGID2476SF is 34 inches minimum to 34.625 inches maximum.
      3. If your measurement falls below 34 inches, proceed to adjust the leveling legs:
      4. If your measurement exceeds 34.625 inches:
      5. Locate the two rear leveling legs at the back bottom corners, accessible by tilting the unit forward slightly or reaching underneath from the front.
      6. Adjust the rear legs using the same 3/8-inch wrench, matching the front leg adjustments to maintain a level plane.
      7. Place a 24-inch spirit level across the top front edge of the dishwasher, running left to right.
      8. Verify the bubble centers between the two lines, indicating perfect level side-to-side.
      9. Rotate the level 90 degrees, placing it front-to-back along the left side edge.
      10. Confirm the bubble again centers, showing proper front-to-back leveling.
      11. Re-measure the floor-to-top height one final time, confirming it reads between 34 inches and 34.625 inches.

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

      1. Locate the drain pump at the bottom center of the dishwasher, directly beneath the sump assembly where water collects during cycles.
      2. Disconnect the gray corrugated drain hose from the pump outlet by squeezing the spring clamp with pliers and sliding it back 2 inches along the hose.
      3. Pull the drain hose straight off the pump outlet—expect approximately 1-2 cups of residual water to drain out into your towels.
      4. Locate the black wire harness connector on the right side of the pump body, measuring approximately 1 inch square with 2 wire terminals (white and black wires).
      5. Press the locking tab on top of the connector with your thumb while pulling the connector straight away from the pump terminals until it releases (requires about 5 pounds of force).
      6. Remove the 3 T20 Torx screws securing the pump housing to the sump assembly, positioned at 12 o’clock, 4 o’clock, and 8 o’clock positions around the pump perimeter.
      7. Rotate the entire pump assembly 1/4 turn counterclockwise while pulling downward to disengage it from the sump bayonet mounting tabs.
      8. Position the new drain pump (part number 154844301) with the outlet port facing toward the right side of the dishwasher.
      9. Insert the pump into the sump opening and rotate 1/4 turn clockwise until the mounting holes align with the threaded inserts in the sump housing.
      10. Install the 3 T20 Torx screws and tighten in a star pattern to finger-tight plus 1/4 turn (approximately 15-18 inch-pounds).
      11. Push the wire harness connector onto the pump terminals until you hear and feel a distinct click, confirming full engagement.
      12. Slide the drain hose onto the pump outlet until it bottoms out (approximately 1.5 inches of insertion depth).
      13. Reposition the spring clamp 1/2 inch from the end of the hose over the pump outlet connection point.
