      • 🔧 Step-by-Step Repair Instructions

      🔍

      🔧 Step 1: Check suspension rods

      1. Unplug the washer power cord from the wall outlet.
      2. Turn off both hot and cold water supply valves located behind the washer by rotating them clockwise until fully closed.
      3. Pull the washer forward approximately 3 feet from the wall to access the rear panel.
      4. Locate the top rear access panel—a white metal cover measuring approximately 24 inches wide by 8 inches tall.
      5. Remove the three Phillips-head screws (#2 size) securing the top rear panel: one screw positioned at the center top edge, and two screws located 2 inches from each side edge.
      6. Lift the panel up and away to expose the four suspension rods.
      7. Identify the four suspension rods extending vertically from the washer tub to the top frame corners—they are silver metal rods approximately 12 inches long with black rubber bushings at each end.
      8. Inspect the top connection points where each rod attaches to the top frame—look for black rubber bushings that should be intact, circular, and compressed evenly around the rod.
      9. Check each top bushing by pressing firmly with your thumb—worn bushings will feel excessively soft, cracked, or missing chunks of rubber.
      10. Inspect the bottom connection points by looking down along each rod to where it attaches to the tub assembly approximately 18 inches below—the bottom bushings should appear identical to the top ones.
      11. Grasp each rod firmly at its midpoint and attempt to move it side-to-side—movement greater than 1/4 inch indicates worn bushings requiring replacement.
      12. Examine all four rods for bending—sight down each rod’s length to verify it remains perfectly straight without curves or kinks.
      13. Look for white or silver metal fatigue marks on the rods, which appear as discolored lines or cracks indicating structural failure.

      🛠️ Step 2: Verify tub not binding

      1. Unplug the washing machine from the electrical outlet and turn off both hot and cold water supply valves located on the wall behind the unit.
      2. Pull the washer away from the wall approximately 3 feet to access the rear panel and provide workspace around all sides.
      3. Remove the top panel by locating two Phillips-head screws at the rear top edge, approximately 2 inches from each side corner, and removing them with a #2 Phillips screwdriver.
      4. Lift the top panel up and tilt it backward to remove it completely from the washer cabinet.
      5. Look down into the tub area and locate the outer tub (white plastic tub) and inner wash basket (stainless steel drum with holes).
      6. Reach down and grasp the inner wash basket with both hands at the 3 o’clock and 9 o’clock positions, placing your palms on the top rim.
      7. Attempt to rotate the basket clockwise, then counterclockwise – it should spin freely with minimal resistance and no scraping sounds.
      8. Push down on the basket with moderate hand pressure (approximately 10-15 pounds of force) and release – it should compress approximately 1-2 inches and spring back smoothly without catching or sticking.
      9. Rock the basket side-to-side by pushing alternately at the 3 o’clock and 9 o’clock positions – you should feel 1-2 inches of movement in each direction with consistent suspension resistance.
      10. Listen for any metal-on-metal scraping, grinding, or rubbing sounds during these movements – complete silence or only soft suspension spring sounds indicate proper clearance.
      11. Shine a flashlight into the gap between the inner basket and outer tub, moving around the entire circumference – you should see a consistent gap of approximately 0.5-1 inch all around with no contact points.

      ⚙️ Step 3: Inspect load distribution

      1. Open the washer lid fully until it stops at approximately 85-90 degrees.
      2. Look into the drum and identify if clothing items are bunched on one side or wrapped around the agitator post in the center.
      3. Reach into the drum with both hands and pull apart any tangled or twisted items, separating sheets, towels, and clothing that have wound together.
      4. Redistribute the wet laundry evenly around the agitator by placing similar-sized items opposite each other – if you place a towel on the left side at the 9 o’clock position, place another towel on the right at the 3 o’clock position.
      5. Spread items in a circular pattern around the drum rather than loading them all on one side – aim for an even ring of clothing approximately 3-4 inches thick around the entire circumference.
      6. Check that no single heavy item (like a wet comforter or bath mat) occupies more than one-quarter of the drum’s circumference.
      7. Press down lightly on four opposite points around the load (12, 3, 6, and 9 o’clock positions) – the resistance should feel approximately equal at all four points.
      8. Verify the agitator cap in the center is visible and not completely covered by clothing piled too high.
      9. Look at the drum from above – you should see an even distribution resembling a donut shape with the agitator in the middle, not a pile on one side.
      10. Close the lid and press the Start/Pause button (located on the control panel at the top right, marked with a triangle symbol) to resume the cycle.
      11. Listen for 30-45 seconds during the spin – a properly balanced load produces a steady humming sound without loud thumping or the drum hitting the cabinet sides.
      12. If you hear repetitive banging sounds louder than normal operation, press Start/Pause again, wait for the drum to stop completely (10-15 seconds), and repeat steps 1-9.

      🔩 Step 4: Adjust suspension if needed

      1. Locate the four suspension rods at each corner of the tub assembly – they’re silver metal rods approximately 18 inches long, extending from the top of the outer tub down to the base frame.
      2. Check each rod’s connection point at the top where it attaches to the tub bracket – look for a hex nut (19mm) threaded onto the rod approximately 2-3 inches below the mounting bracket.
      3. Place a carpenter’s level across the top rim of the inner drum, positioning it front-to-back first, then side-to-side.
      4. If the bubble shows the drum tilting toward the front, identify which front corner sits lower – this indicates that front suspension rod needs lengthening.
      5. Use a 19mm wrench to grip the adjustment nut on the low corner’s suspension rod.
      6. Turn the nut counterclockwise (looking down from above) in quarter-turn increments – each quarter-turn lowers the tub approximately 3mm at that corner.
      7. Recheck the level after each adjustment until the bubble centers within the marked lines.
      8. Repeat the leveling process for the left-to-right orientation, adjusting the side suspension rods using the same 19mm wrench and quarter-turn method.
      9. Press down firmly on each corner of the tub rim with 20-30 pounds of force – the tub should bounce slightly and return to center position without binding or rubbing sounds.
      10. Verify all four adjustment nuts sit at similar heights on their respective rods – they should be within 1/4 inch of each other when measured from the top bracket.
      11. Tighten a jam nut (17mm) located directly below each adjustment nut by turning clockwise with a 17mm wrench – this locks the suspension setting in place and prevents future movement.
      12. Spin the inner drum by hand three complete rotations – listen for any scraping or contact between the drum and tub walls, which indicates further adjustment needed.

      📋 Step 5: Test with balanced load

      1. Open the washer lid completely until it rests against the back hinge stops.
      2. Place 6-8 identical bath towels into the drum, distributing them evenly around the perimeter rather than bunching them on one side.
      3. Add 2-3 T-shirts or similar lightweight items to fill gaps between the towels, creating an even ring of laundry approximately 3-4 inches thick around the entire drum circumference.
      4. Close the lid until you hear it click into the locked position.
      5. Press the Power button located on the top right of the control panel (the button will illuminate blue).
      6. Turn the cycle selector dial clockwise 3 clicks to the “Normal” cycle setting.
      7. Press the Temp button twice to select “Warm/Cold” water temperature.
      8. Press the Spin Speed button once to select “High” spin speed setting.
      9. Press the large Start/Pause button on the right side of the control panel (it will flash for 2 seconds, then remain solid).
      10. Stand directly in front of the washer and observe the entire wash cycle for 40-45 minutes, watching specifically for:
      11. During the final spin cycle, place your hand flat on the top center of the washer lid—you should feel minimal vibration, comparable to a running refrigerator compressor.
      12. When the cycle completes (the control panel will display “End” and beep 3 times), open the lid and verify the load remained evenly distributed and didn’t clump to one side of the drum.

      💡 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.
