      🔧 Step 1: Check pump and drain hose

      1. Unplug the washing machine from the electrical outlet.
      2. Turn off both hot and cold water supply valves located behind the machine by rotating them clockwise until they stop.
      3. Pull the washing machine forward approximately 24 inches from the wall to access the rear panel.
      4. Locate the drain hose—a corrugated gray or black flexible hose approximately 1.5 inches in diameter connected to the back of the machine, positioned 8 inches from the right edge and 18 inches from the bottom.
      5. Disconnect the drain hose from the standpipe or laundry sink by pulling it straight out.
      6. Hold the disconnected end over a bucket and visually inspect inside the hose opening for blockages, lint buildup, or foreign objects.
      7. Insert a flashlight into the hose end and look through the length—you should see light clearly through unobstructed sections.
      8. Remove the three 1/4-inch hex head screws securing the lower front access panel, located 2 inches above floor level across the bottom front of the machine.
      9. Pull the access panel forward at the bottom edge and lift up to release the top clips, then set aside.
      10. Locate the drain pump assembly—a black cylindrical component approximately 4 inches in diameter positioned in the lower right corner, 3 inches from the right side and 4 inches from the front.
      11. Identify the round pump filter cap (approximately 3 inches diameter) on the front face of the pump housing.
      12. Place a shallow pan directly beneath the pump filter to catch residual water (expect 1-2 cups).
      13. Rotate the pump filter cap counterclockwise 1/4 turn until it stops, then pull straight out.
      14. Remove any debris, coins, lint, or foreign objects from inside the filter housing using your fingers.
      15. Shine a flashlight into the now-empty filter cavity and visually confirm the pump impeller (small white plastic propeller) rotates freely when pushed with your finger—it should spin 3-4 complete rotations without resistance or grinding sounds.

      🛠️ Step 2: Clean coin trap filter

      1. Locate the access panel at the bottom front of the washer, positioned 2 inches up from the floor and extending across the lower right corner, measuring approximately 8 inches wide by 4 inches tall.
      2. Insert a flat-head screwdriver into the small slot at the top edge of this access panel, positioned at the center of the panel’s upper edge.
      3. Pry the panel downward and outward using the screwdriver as a lever point—the panel is held by 4 plastic clips and will release with moderate pressure.
      4. Set the access panel aside and locate the circular coin trap cover, which is a round black plastic cap approximately 3 inches in diameter, positioned directly behind where the access panel was.
      5. Place 2-3 bath towels on the floor directly beneath the coin trap opening, extending at least 12 inches outward—approximately 1-2 cups of water will drain out.
      6. Grip the coin trap cover and turn it counterclockwise using both hands until it stops turning, typically 1.5 full rotations.
      7. Pull the coin trap filter assembly straight out toward you—it extends approximately 4 inches and consists of a cylindrical housing with an internal mesh screen.
      8. Empty any standing water from the filter housing into a bucket or allow it to drain onto the towels.
      9. Remove any coins, buttons, lint, or debris visible inside the cylindrical housing and from the mesh screen using your fingers.
      10. Run the filter screen under warm tap water while scrubbing with an old toothbrush to remove accumulated lint and residue from the mesh openings.
      11. Inspect the rubber gasket seal on the coin trap threads—it’s a black rubber O-ring approximately 2.5 inches in diameter—and wipe away any debris or buildup.
      12. Insert the cleaned filter assembly back into the opening, pushing it fully in until it seats against the housing.
      13. Turn the coin trap cover clockwise 1.5 rotations until hand-tight and resistance increases noticeably.
      14. Snap the access panel back into position by aligning the 4 clips and pressing firmly until you hear 4 distinct clicks.

      ⚙️ Step 3: Test pump operation

      1. Locate the drain pump at the lower right front of the washer, approximately 4 inches from the bottom and 8 inches from the right edge when facing the machine.
      2. Identify the drain pump’s white wire connector with 2 wires (black and white) attached to the pump motor terminals.
      3. Set your multimeter to AC voltage mode at 120V range.
      4. Touch the black multimeter probe to the black wire terminal and the red probe to the white wire terminal while the connector remains attached.
      5. Press the power button on the washer control panel to turn the unit on.
      6. Select the “Drain & Spin” cycle using the cycle selector knob.
      7. Press the start button and observe the multimeter reading within 5 seconds.
      8. Confirm you see approximately 120 volts AC on the multimeter display when the pump activates—this indicates the control board is sending power correctly.
      9. Listen for the pump motor humming sound and observe if water drains from the drain hose into your bucket positioned behind the washer.
      10. If voltage is present but the pump doesn’t run, disconnect power, unplug the washer, and remove the white wire connector from the pump by pulling it straight off the terminals.
      11. Set your multimeter to resistance (ohms) mode with range at 200 ohms.
      12. Touch one probe to each of the two metal terminals on the pump motor where the wires connected.
      13. Read the resistance value—a functioning pump shows between 5-15 ohms; infinite resistance (OL on display) means the pump motor windings are open and the pump has failed.
      14. If resistance reads 0-1 ohms, the motor windings are shorted and the pump requires replacement (part number W10876537).
      15. Reconnect the white wire connector to the pump terminals by pushing firmly until it seats fully against the terminal housing.

      🔩 Step 4: Clear any blockages

      1. Locate the drain pump filter access panel at the bottom right front of the washer, approximately 4 inches from the right edge and 2 inches above the floor.
      2. Insert a flathead screwdriver into the slot at the top of the access panel and pry downward to release the two clips holding it in place.
      3. Pull the small black drain hose (approximately 1 inch diameter) from its holder on the left side of the opening.
      4. Place a shallow pan (minimum 2-cup capacity) directly under the drain hose end.
      5. Twist the black cap on the drain hose counterclockwise and pull it straight out to drain residual water into the pan.
      6. Replace the drain hose cap by pushing it in and turning clockwise until snug, then return the hose to its holder.
      7. Grip the large round drain pump filter (approximately 4 inches diameter, located on the right side of the opening) and rotate it counterclockwise one full turn.
      8. Pull the filter straight out from the pump housing.
      9. Remove any debris from the filter screen including coins, buttons, lint, hair, or small fabric items using your fingers.
      10. Insert your index and middle fingers into the circular pump opening where the filter was removed.
      11. Sweep your fingers clockwise around the entire interior circumference of the pump cavity, feeling for and removing any objects, fabric, or buildup.
      12. Run the filter under warm tap water while rubbing the mesh screen with your thumb to dislodge embedded lint.
      13. Inspect the rubber O-ring seal on the filter’s outer edge—it should be continuous with no cuts or flat spots.
      14. Insert the clean filter back into the pump housing, aligning the arrow on the filter with the arrow on the housing.
      15. Rotate the filter clockwise until it stops and sits flush with the pump housing face—approximately three-quarters of a turn.
      16. Snap the access panel back into place by pressing firmly on the bottom edge first, then pushing the top until both clips engage.

      đź“‹ Step 5: Test drainage

      1. Locate the drain pump at the lower right front of the washer cabinet, approximately 4 inches from the bottom and 8 inches from the right side panel.
      2. Place a shallow drain pan or four bath towels on the floor directly in front of the drain pump access area to catch residual water (expect 1-2 cups maximum).
      3. Rotate the drain pump filter cap counterclockwise one full turn while holding a cup beneath it to catch initial water release.
      4. Continue rotating the filter cap counterclockwise 3-4 additional turns until it comes free from the pump housing, revealing the impeller inside.
      5. Insert your index finger into the pump cavity and rotate the impeller clockwise, then counterclockwise – it should spin freely with no grinding sensation or obstruction.
      6. Remove any debris, coins, or lint wrapped around the impeller blades using needle-nose pliers if necessary.
      7. Thread the filter cap back into the pump housing clockwise until hand-tight, completing approximately 5-6 full rotations.
      8. Reconnect the washer to power and turn it on.
      9. Select the “Drain & Spin” cycle using the cycle selector knob positioned at the top center of the control panel.
      10. Press the green “Start” button located at the upper right of the control panel.
      11. Open the washer door and pour 2 gallons of water directly into the drum.
      12. Close the door and observe the drainage cycle – you should hear the drain pump motor activate within 10 seconds, producing a steady humming sound at approximately 60 decibels.
      13. Watch the viewing window on the door as the water level drops completely within 2-3 minutes.
      14. Check underneath the washer and around the drain pump area for any water leaks using a flashlight.
      15. If water drains completely with no leaks and the pump runs smoothly without unusual noise, the drainage system is functioning correctly.
