      📝

      🔧 Step 1: Listen for grinding sounds

      1. Unplug the washer by pulling the power cord from the wall outlet located behind the unit.
      2. Turn off both hot and cold water supply valves by rotating them clockwise until they stop – these are typically located on the wall 12-18 inches above floor level behind the washer.
      3. Pull the washer away from the wall approximately 24-36 inches to allow access to all sides of the unit.
      4. Plug the washer back into the wall outlet.
      5. Turn both water supply valves counterclockwise to restore water flow.
      6. Open the washer lid and position yourself within 2-3 feet of the machine’s left side where the drive motor is located.
      7. Press the power button on the control panel, select the “Normal” cycle, and press “Start.”
      8. Listen during the initial fill phase (first 30-60 seconds) for any grinding sounds coming from the bottom left area where the pump is mounted, approximately 8 inches from the front edge and 4 inches from the left side.
      9. Allow the washer to advance to the agitation phase (begins after water fills to the sensing level) and listen for grinding sounds from the center bottom of the tub where the drive system is located.
      10. Let the cycle progress to the drain phase (approximately 8-10 minutes into the cycle) and position yourself near the front left corner – listen for grinding from the drain pump area, located 6 inches from the front and 5 inches from the left edge.
      11. Continue through the spin cycle and listen for grinding sounds that increase in pitch as the drum accelerates, indicating bearing or drive pulley issues.
      12. Note the specific cycle phase when grinding occurs – fill, agitation, drain, or spin – as this identifies which component is failing.
      13. Press “Pause/Cancel” twice to stop the cycle once you’ve identified when the grinding sound occurs.

      🛠️ Step 2: Test actuator motor

      1. Locate the actuator motor mounted on the top left side of the transmission assembly, approximately 8 inches from the left edge of the washer tub and 4 inches below the top rim.
      2. Identify the white 6-pin wire harness connector attached to the actuator motor – it has a gray locking tab on top.
      3. Press down on the gray locking tab with your thumb while pulling the connector straight away from the actuator to disconnect it.
      4. Set your multimeter to the 200-ohm resistance setting by rotating the dial to the Ω symbol.
      5. Insert the black multimeter probe into the COM port and the red probe into the VΩ port on your multimeter.
      6. Locate pins 1 and 2 on the actuator motor terminal (the two leftmost pins when facing the connector end) – these control the motor winding.
      7. Touch the black probe to pin 1 and the red probe to pin 2, holding firmly for 3 seconds.
      8. Read the resistance value – a functional actuator motor displays between 300 and 500 ohms.
      9. Move the red probe to pin 3 while keeping the black probe on pin 1, then record this reading.
      10. Test all remaining pin combinations: pins 1-4, 2-3, 2-4, and 3-4, recording each resistance value.
      11. Compare your readings: pins showing infinite resistance (OL on display) or readings below 50 ohms indicate a failed actuator motor requiring replacement with part number W10913953.
      12. If all readings fall within the 300-500 ohm range, manually rotate the actuator shaft (the white plastic gear visible on the motor body) clockwise through one complete 360-degree rotation – it should move smoothly without binding or clicking sounds.
      13. Push the wire harness connector back onto the actuator pins until you hear a distinct click, confirming the gray locking tab has engaged.

      ⚙️ Step 3: Check position sensor

      1. Locate the position sensor mounted on the right side of the stator assembly, approximately 4 inches below the top of the tub. It appears as a small black plastic component, roughly 2 inches long, with a white wire connector attached.
      2. Press the release tab on the white 3-pin wire connector and pull straight out to disconnect it from the position sensor. The connector separates with minimal force of 2-3 pounds.
      3. Set your multimeter to the ohms (Ω) setting at 20K range.
      4. Touch the red multimeter probe to the center terminal pin on the sensor connector and the black probe to either outer terminal pin. The reading should be between 10,000 and 13,000 ohms at room temperature (approximately 70°F).
      5. Test the other outer terminal by moving your black probe while keeping the red probe on the center pin. You should get the same 10,000-13,000 ohm reading.
      6. Rotate the tub basket slowly by hand while maintaining probe contact on the sensor terminals. Watch the multimeter display – the resistance should fluctuate smoothly between 8,000 and 15,000 ohms as the magnet ring inside passes the sensor. Erratic jumps, infinite resistance (OL display), or zero resistance indicates sensor failure.
      7. Inspect the sensor body for cracks, discoloration from heat damage, or moisture inside the connector pins. Any visible damage requires replacement with part number W10183157.
      8. If readings fall within range and the sensor body appears intact, reconnect the white 3-pin connector by pushing firmly until you hear a distinct click, indicating the locking tab has engaged.
      9. If readings were out of range, remove the single T20 Torx screw securing the sensor to the stator bracket and pull the sensor straight out. Install the replacement sensor, secure with the T20 screw tightened to finger-tight plus one-quarter turn, then reconnect the wire harness.

      🔩 Step 4: Replace shift actuator if needed

      1. Locate the shift actuator mounted on the left side of the transmission assembly, approximately 8 inches up from the base of the washer tub.
      2. Identify the white plastic shift actuator housing with a gray motor attached – it measures roughly 4 inches long by 2 inches wide.
      3. Disconnect the wire harness connector from the actuator by pressing the locking tab on top of the connector with your thumb while pulling the connector straight away from the actuator body.
      4. Remove the single 1/4-inch hex head mounting bolt securing the actuator to the transmission bracket using a 1/4-inch nut driver, turning counterclockwise 4-5 full rotations.
      5. Grip the actuator body firmly and pull straight out away from the transmission – you’ll feel resistance for the first 1/2 inch as the actuator shaft disengages from the transmission shift mechanism.
      6. Inspect the white plastic drive coupler on the end of the old actuator shaft – if it shows rounded edges, cracks, or missing teeth, replacement is necessary.
      7. Align the new shift actuator (part number W10913953) so the shaft points toward the transmission opening and the mounting hole lines up with the bracket hole.
      8. Push the actuator shaft into the transmission opening until the mounting hole aligns perfectly with the bracket – the shaft will insert approximately 1 inch deep.
      9. Insert the 1/4-inch hex head bolt through the bracket and into the actuator mounting boss, turning clockwise by hand until finger-tight.
      10. Tighten the mounting bolt with the 1/4-inch nut driver to snug fit – approximately 20-25 inch-pounds (do not overtighten as the plastic housing can crack).
      11. Push the wire harness connector onto the actuator terminals until you hear and feel a distinct click, confirming the locking tab has engaged.
      12. Verify the connector cannot be pulled off without depressing the locking tab.

      📋 Step 5: Test agitate and spin modes

      1. Plug the washer power cord back into the wall outlet.
      2. Turn the water supply valves (located on the wall behind the washer) clockwise to the fully open position.
      3. Open the washer lid and fill the tub with water to approximately 6 inches deep, or press the power button and select a small load wash cycle to add water automatically.
      4. Press the power button once. The display panel will illuminate showing “0:00” or the default cycle time.
      5. Rotate the cycle selector knob (located at the top right of the control panel) to the “Normal” wash setting. You’ll hear a single click as it lands on each position.
      6. Press the “Start/Pause” button once. The lid lock will engage with an audible click within 3-5 seconds, and the red lid lock light will illuminate.
      7. Watch the agitator (the plastic post in the center of the tub) for 30-45 seconds. It should rotate back and forth in 180-degree sweeps, creating a swirling water motion. The agitation speed should be approximately 60-70 strokes per minute.
      8. Press “Start/Pause” to stop the cycle after verifying agitation works properly.
      9. Rotate the cycle selector knob to the “Spin Only” or “Drain & Spin” setting (approximately 6 positions clockwise from Normal).
      10. Press “Start/Pause” again. The tub should begin draining first if water is present, taking 2-3 minutes to empty completely.
      11. Once drained, the spin basket will accelerate gradually over 20-30 seconds, reaching a maximum speed of approximately 700 RPM. You’ll hear the motor pitch increase as speed builds.
      12. Allow the spin cycle to run for 60 seconds to verify smooth operation without excessive vibration or grinding noises.
      13. Press “Start/Pause” to stop the test cycle. The spin basket will coast to a complete stop within 15-20 seconds.

      💡 Pro Tips

      Take photos as you disassemble components – they’ll be invaluable when putting everything back together. If you encounter resistance or something doesn’t seem right, stop and reassess rather than forcing it.
