      ⚡

      🔧 Step 1: Test lock actuator

      1. Unplug the washer from the electrical outlet or flip the circuit breaker to cut power to the unit.
      2. Open the washer door fully and locate the door lock assembly on the right side of the door opening, approximately 2 inches from the top edge of the door frame.
      3. Use a Phillips-head screwdriver #2 to remove the 2 screws securing the front panel’s top right corner near the door lock area.
      4. Grasp the top of the front panel firmly with both hands and pull it forward approximately 1 inch, then lift upward to disengage the 6 bottom clips. Set the panel aside.
      5. Locate the door lock actuator—a gray rectangular component measuring approximately 3 inches wide by 2 inches tall, mounted directly behind where the door latch engages.
      6. Identify the wire harness connector attached to the back of the lock actuator—it has 5 wires (typically black, white, red, brown, and orange).
      7. Press the tab on top of the connector and pull it straight back to disconnect it from the lock actuator.
      8. Set your multimeter to continuity mode (ohms setting).
      9. Locate pins 1 and 2 on the actuator connector (with the tab facing up, these are the two leftmost pins on the connector body itself).
      10. Touch one multimeter probe to pin 1 and the other to pin 2. A working lock actuator shows 50-150 ohms resistance.
      11. Now test pins 3 and 4 (the two rightmost pins). You should read 1500-2000 ohms.
      12. If either reading shows infinite resistance (OL on the meter) or zero resistance, the lock actuator has failed and requires replacement (part number 137353320).
      13. If readings are within range, reconnect the wire harness by pushing the connector firmly onto the actuator pins until you hear an audible click.

      🛠️ Step 2: Check door closure

      1. Open the washer door fully until it stops at its maximum open position (approximately 90 degrees from the front panel).
      2. Look at the door latch mechanism located on the right side of the door opening, positioned 2 inches from the top edge of the opening.
      3. Identify the gray plastic latch striker on the door itself – this is the protruding rectangular piece measuring approximately 1 inch wide by 1.5 inches tall with a metal pin through its center.
      4. Close the door slowly and watch where the striker aligns with the latch receptacle in the door frame – the striker should enter the receptacle opening dead center without touching the top, bottom, or sides.
      5. Listen for two distinct clicks as the door latches: the first click occurs when the door contacts the receptacle, the second click happens when the lock mechanism engages (approximately 0.5 seconds later).
      6. Grip the door handle and pull outward with moderate force (about 10 pounds of pressure) – the door should remain firmly closed and not open.
      7. Place a standard sheet of printer paper (8.5 x 11 inches) between the door gasket and the front panel at the 12 o’clock position.
      8. Close the door completely and attempt to pull the paper out – you should feel significant resistance, and the paper should tear rather than slide out easily.
      9. Repeat the paper test at the 3 o’clock position (right side), 6 o’clock position (bottom center), and 9 o’clock position (left side).
      10. Check the door gasket for the gray rubber seal making complete contact with the white painted metal front panel around the entire circumference – no gaps larger than 1/16 inch should be visible at any point.
      11. If the door fails to click twice, doesn’t seal paper firmly at all four positions, or shows gaps larger than 1/16 inch, the door latch or hinges require adjustment or replacement.

      ⚙️ Step 3: Replace if door won’t secure

      1. Open the washer door fully until it stops at approximately 90 degrees from the cabinet face.
      2. Locate the door strike on the right side of the door opening, positioned 3 inches down from the top edge of the cabinet opening – this is a black plastic component with a protruding hook mechanism.
      3. Use a T20 Torx bit screwdriver to remove the 2 screws securing the strike plate, positioned vertically 1.5 inches apart on the strike assembly face.
      4. Pull the strike assembly straight toward you with steady pressure – it will release from the cabinet slot after moving approximately 0.5 inches forward.
      5. Disconnect the single white 2-wire connector located behind the strike assembly by squeezing the plastic tab on top while pulling the connector halves apart.
      6. Remove the old strike assembly completely from the cabinet.
      7. Take your replacement door strike (part number 137353320) and connect the white 2-wire connector to the matching connector on the strike assembly – push together until you hear an audible click.
      8. Align the strike assembly with the rectangular mounting slot in the cabinet, ensuring the hook mechanism faces toward the door seal.
      9. Push the strike assembly into the cabinet slot until it sits flush with the cabinet edge – the mounting holes will align automatically.
      10. Thread both T20 Torx screws into the mounting holes and hand-tighten initially.
      11. Use the T20 Torx bit to tighten both screws in alternating passes (top screw, then bottom screw) until snug – approximately 8-10 inch-pounds of torque.
      12. Close the door and verify the hook engages with the strike mechanism – you’ll hear a distinct double-click sound when the door fully latches and the lock engages within 2 seconds.

      🔩 Step 4: Test lock operation

      1. Close the washer door completely until you hear it click into the latch mechanism.
      2. Press the Power button on the control panel located at the top center of the machine to turn the washer on.
      3. Press and hold the “Control Lock” button (shows a padlock icon with a smiling face) for 3 seconds until you hear a single beep and see “CL” or a lock icon appear on the LED display.
      4. Attempt to open the door by pulling the handle – the door should remain firmly locked and not budge at all.
      5. Try pressing various cycle buttons on the control panel – the display should show “CL” or the lock icon, and no buttons except Power and Control Lock should respond to your touch.
      6. Listen for the door lock solenoid engagement – you should hear a distinct clicking or buzzing sound from the door lock assembly located at the front right corner of the door opening, approximately 2 inches down from the top edge.
      7. Select any wash cycle (such as Normal or Quick Wash) and press Start/Pause – the door should remain locked, and within 3-5 seconds you should hear the lock mechanism engage with a second, louder click.
      8. Wait 10 seconds, then press Start/Pause to stop the cycle.
      9. Press Power to turn off the machine – the door lock should disengage within 2-3 seconds, indicated by a clicking sound.
      10. Pull the door handle to verify it opens freely.
      11. Repeat steps 2-10 two more times to confirm consistent lock and unlock operation.

      đź“‹ Step 5: Verify security

      1. Rock the washer drum forward and backward with both hands placed at the 3 o’clock and 9 o’clock positions on the drum opening. The drum should move no more than 1/4 inch in any direction.
      2. Grasp the drum at the top center (12 o’clock position) and pull straight toward you with moderate force (approximately 20 pounds of pull). The drum should remain firmly in place with no clicking or popping sounds.
      3. Locate the 4 suspension rods at each corner of the drum assembly – front left, front right, rear left, and rear right. Each rod connects from the top of the outer tub to the cabinet frame.
      4. Visually inspect each suspension rod connection point where it attaches to the cabinet frame. Look for the silver metal bracket with a white plastic bushing. The rod should be fully inserted through the bushing with no gap visible.
      5. Check each of the 4 shock absorbers located at the bottom corners of the tub assembly. Each shock absorber is a black cylindrical tube approximately 8 inches long. Verify the mounting bolts at both the top and bottom attachment points are tight.
      6. Use a 10mm socket wrench to test-tighten the shock absorber mounting bolts. Turn each bolt clockwise – if any bolt turns more than 1/8 turn, continue tightening until snug (approximately 15-18 ft-lbs).
      7. Spin the drum clockwise by hand for 3 complete rotations. Listen for any rattling, grinding, or scraping sounds. The drum should rotate smoothly and quietly.
      8. Check all wire harness connections you reconnected in previous steps. Pull gently on each connector – it should resist with no movement if properly seated.
      9. Verify the door boot (rubber gasket) is seated completely in the front panel groove around the entire circumference with no bulges or gaps visible.

      đź’ˇ 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.
